The automotive industry stands out from other industries due to the particularly wide variety of components made from different materials.
Whether they are cast, forged, stamped or turned parts requiring surface treatment, or plastic parts that need to be coated: each one poses specific challenges for surface treatment.
At Walther Trowal, we understand the requirements of the Automotive industry, drawn from hundreds of successful applications, and we quickly develop component- and application-specific solutions for surface treatment. In doing so, we always keep a close eye on the integration of the machines into your production processes and on cost-effectiveness.
Processing of cast, forged, stamped or turned parts
Decorative coating of control buttons or knobs
Descaling of connecting rods and edge rounding of belt lugs
Polishing of high-performance components for motorsport
Functional coating of seals and O-rings, for example with lubricants
For complex geometries
Mass finishing technology
Mass finishing is the method of choice for deburring, edge rounding and smoothing steel and light-alloy components fitted in vehicles, such as turned and milled parts for gearboxes, the chassis, bearings or clutch components.
Efficient Descaling and Cleaning
Blasting technology
Blasting is frequently used on forged and die-cast components, for example to remove scale and perform Cleaning on connecting rods, cylinder head covers, steering knuckles, pump casings or wheels.
Efficient coating of large quantities
Small parts with a perfect finish
Small parts produced in large quantities are given the perfect finish in Rotamat machines. Small control buttons are given a decorative coating; in the case of O-rings or flat gaskets, the focus is usually on functional coatings, such as anti-seize coatings.
