For over 85 years Walther Trowal has been a pioneer and market leader in various surface treatment technologies. The company offers modular and custom engineered solutions for a wide range of surface treatment problems.
Initially only making vibratory finishing equipment, over the years Walther Trowal has continuously broadened its product range and today offers a wide portfolio of equipment and services for improving all kinds of surfaces, e.g. mass finishing, part cleaning, shot blasting and drying of a wide spectrum of work pieces, last but not least, the coating of mass produced small parts.
Walther Trowal offers not only various types of equipment but complete surface treatment systems: By linking the various equipment modules and automating the complete process, we are able to precisely adapt our process technologies to the technical requirements of our customers.
This also includes various types of peripheral equipment and process water cleaning and recycling systems.
As a surface processing specialist, Walther Trowal offers a wide range of processing types to help you achieve the perfect result.
Whether you want to evenly blast your workpieces, clean components or coat small parts made from a variety of materials, we can develop the ideal process that allows you to work productively and efficiently to stay competitive.
From deburring and rounding to high-gloss polishing, circular vibrators are universal mass finishing machines that can help you process a wide range of materials. You can use them for roughly pre-grinding workpieces, for example, or for producing surfaces ready for electroplating. Circular vibrators work extremely efficiently, making them suitable for use as both stand-alone units or as part of automated production procedures.
Continuous blasting – Excellent, highly automated processing. The selected blasting medium is directed towards your workpieces at high speed using blast wheels. This ensures high blasting performance and optimum use of energy. Using this technology in a continuous process offers several advantages over batch processing:
Continuous workpiece feeding
Easy to integrate into production processes
Simplified parts flow
The Rotamat coaters are the economic solution for improving the surface of mass produced small parts by coating made from elastomers, metal or wood – for example, O-rings, handles, springs or screws.
Even parts that have a complex shape or are extremely delicate are discharged from the machine with a perfect coating and completely dry.
The coating process in the rotary drum is full automatic.
