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.
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.
As previously discussed in our Automation Blog Series, building a robotically assisted process requires evaluating your surface finishing system along with its problems and goals and selecting the right machine and consumables. Automating a mass finishing or shot blasting process also requires selecting the automated hardware that will best achieve your overall goals and provides the most efficiency in terms of time and manual labor.
An experienced partner such as Rosler Metal Finishing can provide insight and advice on the numerous material handling tools specially designed or adapted to mass finishing and shot blasting process improvement.
Work Piece Loading Systems
Including skip loaders, lift and tip loaders, vibratory feed hoppers, and other tools, work piece loading systems are ideal for small- to mid-sized work pieces handled in bulk.
To this day, the surface of large structural
aircraft components is frequently finished by hand. This process is not only
costly, but extremely inefficient and hard to replicate with absolute
Rosler Metal Finishing is changing the notion that suitable mechanical finishing equipment is not available for large, structural aerospace components by offering mass finishing technology capable of solving this problem and providing fully automatic finishing of work pieces up to 30 feet long.

Thanks to the development of large, powerful vibratory tubs manual deburring and grinding of large aircraft components can now be eliminated. The development of perfectly controlled mechanical finishing systems offers finishing solutions for applications where the biggest rotary vibrator, because of the size of the parts, might still be too small.
