Forge & Foundry, Part 12 – Media and Compound Selection, Effluent Handling Drive Success

Regardless of the industry , the selection of media and compounds utilized in mass finishing can elevate or hinder finishing results. The handling of effluents – used process water – also factors into a process’ efficiency and end results. With more than 80 years of experience, Rosler understands the demands of the forge and foundry industries specifically and how to achieve precise and consistent finishing results by combining the latest technology, well-designed machines, and consumables . This installment of the Forge & Foundry Blog Series highlights how careful media and compound selection along with proactive handling of effluents assist in producing mass finishing efficiencies. Ingredients for Success Media and compounds are more than just “rocks” and “soap” thrown into a mass finishing machine. Instead, these consumables are sophisticated tools that can make a mass finishing process a success or a failure. Media choice with regard to shape, size, composition, and abrasiveness is as important as selecting the right machine. Selecting the wrong media could be detrimental to the process. The level of media in a machine is equally important. If not introduced in the prescribed ratio, even the best suited media will fail to deliver the desired results. For example, increasing the ratio of media relative to the work pieces has a cushioning effect and helps prevent unwanted work piece damage in the form of nicking. Conversely, skimping on media levels can produce ineffective finishing as well as work piece damage. Much like media, the compound selection must match the work piece material. For example, aluminum die-castings require a different compound than die-castings made from magnesium. Applying compounds in the prescribed dosage is also key to maintaining finishing results. For example, insufficient compound usage can cause foaming in the machine and discoloration of finished work pieces. Handled with Care Mass finishing produces an effluent containing media and metal fines, various chemicals from the compounds, and sometimes even chelated metals. At this point a decision must be made; will the effluent be cleaned and recirculated or discharged as waste? In either case, contaminants must be removed first. When discharging as waste, all contaminants must be removed to prevent pollution issues and discharge fines. Additional mass finishing process efficiency and greater ROI can be attained by cleaning effluent for reuse. The use of centrifugal filters is an excellent treatment method for effluent which factors in added benefits including reduced water usage and compound longevity. Rosler Centrifuge Technology By removing all solids in the form of media and metal fines from the mass finishing effluent, centrifuges allow the cleaned liquid, now free of any solids, to be reused by recycling it back to the mass finishing machine. This can result in water consumption savings of more than 90 percent. Since centrifuges do not degrade the compound in the process liquid, drastically reduced usage of compounds may also be achieved.

Rösler cleaning centrifuge in the glass industry reduces costs by 90%

Easy operation thanks to fully automatic processing The automatic RZ 150 A is designed to handle a throughput of 150 liters per minute. In conventional systems the peeling knife, driven by a gear motor, is constantly rotating with the drum. In contrast to this the peeling knife of the Rösler RZ 150 A, located in the center of the sludge drum, is stationary. Only when the sludge deposits in the drum must be discharged, is the peeling knife moving towards the drum wall with a pneumatically actuated linear guide system. This allows peeling the sludge from the drum wall without placing any additional load on the drum bearings. After completion of the peeling cycle the drum is automatically rinsed to remove any residual sludge deposits. This prevents imbalances during the subsequent cleaning cycle, which could lead to premature wear of the drum bearing. The fully automatic process helps saving costs and reduces the consumption of valuable resources. Mr. Stepa, general manager of HART-SM, explains: „The new cleaning centrifuges helped us to reduce our energy consumption and achieve substantial cost savings. For example, we could reduce our idle machine times by 90 percent. And since only the water losses due to evaporation must be replenished, we could significantly reduce the costs for water exchanges. Last-but-not-least, we could reduce the monthly consumption of coolant from about 1,500 liters down to 150 liters, a reduction by nearly 90 percent. In addition to the considerable financial and technical benefits we also achieved a significant improvement of the water quality, an important factor for us as a progressive, future-oriented company. The water system is clean, because it is no longer overloaded with calcium. As a matter of fact, it is totally free of solid particles, which has an extremely positive effect on the overall quality of our products.” Mr. Stepa continues: “The cleaning centrifuge from Rösler represents an innovative solution that brings about a significant added value to our operation. And, of course, it is perfectly in line with our vision for a clean environment. We are pleased to have a company like Rösler as our reliable partner!” Rösler cleaning centrifuges – efficient and effective cleaning of industrial liquids Whether a company has to deal with coolants, sludge from paint processes, the water from industrial work piece cleaning operations or other process liquids, the treatment of the contaminated liquids always depends on the quality of the applied cleaning technology. No doubt the innovative, well-designed centrifugal filtering technology from Rösler offers excellent solutions. To achieve optimum cleaning results for the various industrial liquids, the centrifugal systems are specially adapted to the individual customer requirements. The Rösler centrifuges offer not only numerous technical and financial benefits, but through significant savings of water and other production materials they also help protect the environment. With decades of experience in the field of centrifuges Rösler is a competent, qualified partner for the efficient, energy-saving cleaning of all kinds of industrial liquids.

Mass Finishing Success Requires Constant Operational Focus

When most companies take on capital expenditure projects such as purchasing mass finishing equipment, very careful attention is paid to investing in the most productive, cost‐efficient equipment as possible to achieve the best possible quality. Operational efficiency is often another story. Once the equipment is up and running routine takes over and less attention is paid to keeping the equipment operating at its peak performance. Whether the machinery is never calibrated to reach its fullest potential or the on-going process is not carefully monitored once the process is dialed in, lacking operational focus can be costly and counterproductive. Figuratively speaking, poorly managed mass finishing operations are pouring money down the drain! Rosler works with its clients to ensure that our machinery delivers initial success and continues to provide precise, repeatable results long into the future by promoting operational attention and heading off costly mistakes. Consequences of Inattention For mass finishing processes, the lack of operational focus may take many forms individually or simultaneously, including: Reduced capacity because of processing times becoming unnecessarily longer. Overall poorer finishing qualities. Unstable processes with erratic finishing. Work pieces requiring additional reprocessing and higher rejection rates. Equipment not providing expected results and return on investment. Such operational deficiencies can cost a lot of money in the short-term when it comes to meeting client expectations and standards as well as the long-term life expectancy and usefulness of the process and machinery utilized. Identifying Issues and Opportunities Careful monitoring of the key process parameters, quick correction of any process abnormalities or “trouble shooting,” and regular preventive maintenance will ensure that a finishing process runs as intended in a cost‐efficient manner. Of course, this should not prevent a company from looking for further improvement and optimizing its current finishing operation. Technical upgrades or new, improved media and/or compounds may have become available for existing equipment which could help increase productivity, reduce costs, and improve the finishing quality. When working with a trusted partner and mass finishing expert such as Rosler, upgrades and advances can often be implemented without completely overhauling a process or purchasing entirely new systems. Optimizing Mass Finishing Operations Achieving the best results from a mass finishing process requires understanding the interaction between the various process components, including: The finishing machine itself. Compounds (liquids, recycling, powder, grinding, polishing, dry polishing, and cleaning/degreasing) and process water. Media – whether ceramic , plastic , or polishing and drying . The success of mass finishing depends on the successful pairing of machines, media, and compounds/water. The desired finishing results – deburring, edge radiusing, cleaning (de‐oiling, descaling) , and surface smoothing and/or polishing – can only be achieved if these process components are carefully calibrated with each other. More than a dozen factors are in play in a mass finishing process and enough complexity to warrant involving experts with experience. Process water from the finishing machine must also be addressed and monitored for optimum results. Depending upon the work piece’s material and original condition as well as the processes performed and consumables used, process water may be contaminated with media and metal fines, chemicals from the compounds, and even chelated metals. Before the process water can be discharged to drain or re‐used in the finishing process, it must be cleaned with a centrifuge .

New Vibratory Finishing System Enhances Existing Material Handling & Drying Equipment

When it comes to high-volume production of complex aluminum die-castings, Kovolis Hedvikov a.s. (Kovolis) is a sought after partner by numerous car manufacturers and their suppliers. To expand its capacity and achieve more flexibility in the overall manufacturing process, the company purchased a continuous flow vibratory finishing system from Rosler designed to handle a wide work piece spectrum and custom engineered to fit into the available space at the customer’s premises. About Kovolis Founded in 1816 as an ironworking operation, Kovolis has focused entirely on aluminum die casting since 1945. Today, Kovolis produces components from nine different aluminum alloys weighing between 7 oz (200 grams) and 18 lbs (8 kg) with different casting technologies including vacuum investment casting and rheocasting. Their product range includes brakes, power steering systems, turbo chargers, and compressors for air conditioning systems. Kovolis customers are renowned car manufacturers and tier-1 suppliers that also utilize the company as an important partner for product development, machining, heat treatment, and surface finishing services. New Needs Call for a New System Jiri Buzek, manager of foundry III at Kovolis, explained the need for a new vibratory finishing system. “Our product portfolio underwent a drastic change in the past years. The trend goes more and more to larger and more delicate components, which require a vibratory finishing step after punch deburring for their downstream handling. Our existing finishing system was not designed for this and had also reached the end of its productive service life.” The new system not only had to cope with larger work pieces, but the finishing process also had to be a lot gentler. Additional customer requirements were high equipment uptimes and cost efficiency. And, above all, the new finishing system had to be integrated into the existing manufacturing operation, utilizing the existing work piece loading device and hot air belt drier. The planning engineers at Kovolis submitted these specifications to two German equipment suppliers. “We decided to go with the Rosler continuous feed vibratory finishing system, because it offers ample capacity, and Rosler met all our special technical requirements. Of course, the fact that our company has had excellent experience with other equipment from the same supplier certainly helped,” Buzek said. The single curve U-shaped cross section of the processing channel guarantees the optimum movement of the media and work pieces through the machine. Kovolis also appreciates that Rosler can supply the equipment as well as all compounds and finishing media needed. This allows the perfect adaptation of the finishing process to the customer’s work pieces. A Customized Solution The new finishing system consists of a linear continuous feed machine, type R 550/4600 DA, with a usable length of 15 ft (4.6 m). The functions of the existing work piece loading system and hot air belt drier were integrated into the overall system controls. “Rosler met all our technical requirements and provided valuable support in optimizing our finishing process,” Buzek said. The system offers a number of features and capabilities, including: Fully automatic feeding of the work pieces every 30 seconds. Accommodation of parts with diameters of up to 16 in (400mm). Adjustable processing times. Dual-stage separation with rinsing station. Process water cleaning with an automatic centrifuge. The processing bowl angle can be adjusted to change the processing time. Kovolis was especially impressed with the centrifuge technology Rosler offers. “In the past we cleaned our process water chemically or with a semi-automatic centrifuge. This was highly labor intensive and costly” Buzek said. “With respect to process water-cleaning, Rosler provided us again with the optimum solution. “We are certain that with the new equipment we will not only improve the quality of our finishing operation but, at the same time, will become more cost efficient.” The Rosler Way As the international market leader, Rosler offers total solutions in the field of mass finishing and shot blasting, painting and preservation systems, and mass finishing consumables.

Forge & Foundry, Part 11 – Top Mass Finishing Machines for Cleaning Die Castings

Rosler Metal Finishing has decades of experience in the forge and foundry industries, especially when it comes to mass finishing for die-casted work pieces. Our Forge & Foundry Blog Series continues with an overview of our top five mass finishing machines for precise cleaning of die castings. Standard Rotary Vibrators Media and parts are placed into a circular processing bowl in standard rotary vibrators . The energy from a vibratory motor causes the media and parts to freely tumble over each other. Some models are equipped with an internal separation device for separating the finished work pieces from the media. Rotary vibrators can be used for batch and continuous feed processing. The R620 Euro is one of Rosler's standard rotary vibrator models Rosler’s standard rotary vibrator models include the models EC, Euro, A, and R. Ideal Work Pieces — Small to fist-sized die-castings such as shoe buckles, furniture fittings, gear shifter forks, electrical components Work pieces processed by one of Rosler's standard rotary vibrators Learn more about these machines in our Rotary Vibrator Guidebook (PDF) . Long Radius Rotary Vibrators Built upon the rotary vibrator technology, long radius machines feature much bigger overall diameter and larger processing bowls. The expanded processing area allows for considerably longer cycle times in continuous feed mode. Known as the LR models at Rosler, these machines allow for batch and continuous feed processing. Rosler's LR models are long radius rotary vibrator machines Ideal Work Pieces — Small- to mid-sized die-castings including small gear boxes, bearing housings, mirror frames for cars, all kinds of engine and transmission components Work pieces processed by one of Rosler's long radius rotary vibrators Learn more about Rosler’s LR capabilities in our Long Radius Guidebook (PDF) . Multi-Channel, Continuous Flow Rotary Vibrators The major difference between a multi-channel, continuous flow rotary vibrator and a standard rotary vibrator is the processing channel’s spiral arrangement to create extremely long processing channels of up to 31 ft (9.5 m). The unique channel design draws work pieces apart so they almost never touch each other during the finishing process and always features continuous feed processing. Rosler’s linear, continuous flow vibrators are known as the SE models. The Rosler SE model is a multi-channel rotary vibrator Ideal Work Pieces — Small to mid-sized somewhat delicate components, particularly parts with critical sealing areas that must not be damaged including parts for espresso machines and model train cars Model train cars processed by one of Rosler's Multi-channel continuous flow rotary vibrators machines More information is available in our Multi-Channel Continuous Flow Systems Guidebook (PDF) . Linear, Continuous Flow Vibrators Powerful vibratory drive systems are mounted underneath rectangular processing bowls in linear, continuous flow vibrators. They always feature continuous feed processing. Known as DA models at Rosler, these machines are the largest and most powerful mass finishing machines available. Rosler's linear continuous flow vibrator machine offerings include this DA 650 6600 Ideal Work Pieces — Mid-sized to large, somewhat sturdy, die-castings that are not damaged by tumbling over each other including power drill housings, cylinder head covers, oil pans, transmission housings, disks for automatic transmissions Impact wrench housings processed by one of Rosler's linear continuous-flow vibrators Learn about Rosler’s DA capabilities in our Linear, Continuous Feed Systems Guidebook (PDF) .

Automation, Part 6—Environmental Considerations of Automation

Technology has transformed almost every aspect of life and the shop floor is no exception. As explored in previous Automation Blog Series posts, Rosler Metal Finishing believes automation represents the new norm in mass finishing and shot blasting . In the face of increasing competition, manufacturing interests will continue to demand lower cost, higher efficiency, and greater flexibility from their chosen surface finishing partner. Though it would appear that any downsides of automation are outweighed by its benefits, there’s a delicate balance to be struck when it comes to a symbiotic relationship with the world outside of the machine. Having previously discussed how human effort and ingenuity will work in harmony with automated processes, we now turn our attention to environmental considerations—namely, how automated machines used in mass finishing and shot blasting can impact the earth’s resources, and how manufacturers can mitigate that impact. The International Institute for Sustainable Development notes that the rise of automation has thrust us into a “Fourth Industrial Revolution,” citing energy use, resource use, and ecosystems as the three most critical factors to watch as more automated processes are implemented. These are important considerations, given that manufacturers often are targeted in headlines about waterway pollution and even global warming, but responsible manufacturing practices can help avoid the most egregious impacts and keep manufacturing operations in compliance. Process Water Handling In the process of mass finishing and wet blasting, the biggest consideration is with regard to the process water discharged from the finishing machines. Often, this water is tinged with metal and media fines; at times, it can also contain oil and dissolved metal. Of course, process water will carry the compound being used in the specific finishing process. Mass finishing process water in different cleaning stages. So how can operators of automated mass finishing machinery take special consideration to limit the contamination of any process water discharged from the plant? There are two main ways to effectively curtail such constituents. Central Treatment The establishment of a protocol that includes a central wastewater treatment plant is quite effective in removing contaminants. Also, such facilities require fewer dedicated staff members, which adds to the efficiency of this approach. Centrifuges This universal cleaning system is deployed to separate, purify, extract, and wash various materials using centrifugal force to generate 2,000 times the earth’s normal gravity. These systems also require little operator attention, can be acquired in completely automated or semi-automated configurations, and can be used for most standard mass finishing applications. Rosler offers two centrifuge models; the semi-automatic Model Z 800 and the fully automatic Z 1000. Rosler's Z 800 centrifuge is semi-automatic. Rosler's z 1000 centrifuge is fully automatic. With the right approach to treating discharged process water, you can ensure you are a good steward of your environment, while also maximizing the efficiencies and benefits to be gained from automating your mass finishing and wet blasting operations. The Rosler Way The experts at Rosler are uniquely qualified to develop an automated finishing process for your surface finishing needs that is both effective and ecologically responsible.

Rosler & Lumag – Combining Multiple Solutions in a Single Finishing System

Finding a solution to our clients’ needs is nothing new for Rosler , nor is combining multiple solutions into a single finishing system. Take our work with Polish brake pad manufacturer Lumag Sp. z o.o. (Lumag) , for example. When they faced the challenge of de-oiling, deburring, and surface roughening brake pad carrier plates as part of their punch press process, they turned to us for a cleaning and mass finishing solution. The Situation Upon its founding in 1988 by Marek Zak, Lumag specialized in the production of brake linings. As the company implemented its own brake pad manufacturing technology, their products and offerings evolved. In addition to achieving enormous technological progress and applied engineering solutions, Lumag amassed a collection of machinery in need of constant upgrades and integration. In order to meet the continuous rise of quality and safety standards for its brake pads for drum and disk brakes for commercial vehicles as well as brake pads for passenger cars and motorcycles under the trade name Breck , Lumag needed a partner with automotive expertise who could combine multiple solutions in a single system. De-Oiling, Deburring, and Surface Roughening With the change of its production method for the brake pad carrier plates from casting to stamping , Lumag decided to install a new in-house manufacturing line for these products. The new system must allow for stamped carrier plates with lengths of 8-10 in (210-250 mm) and widths of 3-5 in (90-110 mm). The work pieces also have a slit or drilled hole to allow a sensor to monitor brake pad wear after installation and must undergo de-oiling, deburring, and surface roughening during the finishing process. These steps are necessary to ensure that the delicate stampings provide optimum adhesion characteristics for the subsequent bonding of the brake pads. Another requirement presented by the customer was to directly link the finishing equipment with the punch press while providing extremely gentle processing and the complete automation of the cleaning (de-oiling) and mass finishing stages in a continuous feed operation. In addition to an excellent reputation in the industry, Rosler’s ability to supply the equipment for both processes and the finishing media and compounds from one single source was a bonus for Lumag. Intelligent Media Selection Allows for Cleaning Without Drying After the stamping process, a conveyor belt transfers the work pieces to the drum washing machine equipped with an internal transport auger. In the drum the carrier plates initially pass through an un-perforated zone into which cleaning liquid is applied by spray nozzles. This creates an immersion bath for de-oiling. In the following perforated drum section, the cleaning liquid is drained, and in a secondary de-oiling step the work pieces are spray washed. This cleaning zone is followed by a drip-off section, a rinse station, and another drip-off section. Complete Rosler system with transport container Subsequently, a conveyor belt transfers the work pieces into the mass finishing machine. Replenishment of the cleaning liquid takes place with a Dosatron proportional dosing pump. Since the cleaning liquid and the compound for the mass finishing process have practically the same chemical characteristics—including the placement of a temporary corrosion protection—carryover of the cleaning liquid into the mass finishing machine presents no issue. This clever trick eliminated the need for a drying stage after the cleaning process, resulting in significant savings in the overall capital expenditure as well as reducing operating costs. For proper maintenance of the cleaning liquid the washing machine is equipped with filtration units and an oil separator. Gentle Mass Finishing Deburring and surface roughening of the work pieces takes place in a linear, continuous flow vibrator R 550/6600 DA with a specially adapted work piece loading system. Loading actually takes place at the rear end of the processing bowl instead of on the lateral bowl side with greatly reduced dropping heights. Similar gentle work piece transfers were incorporated in the vibratory screening unit and the drier filled with Supervelat drying media. After drying a certain work piece quantity based on precisely measured weight, components are discharged into a transport bin. The process water from the mass finishing machine is continuously cleaned in a fully automatic peeling centrifuge Z 1000 equipped with automatic sludge discharge.
