Practical Test of a Manual Powder Coating Gun

Ice Clean

Martin Bilz

Blasting with dry ice and CO snow are becoming increasingly popular as alternatives to conventional cleaning processes in a wide range of applications. Many people are unaware of the differences between the various types of CO blasting or of the areas in which they can be used, their benefits and their limitations. This article provides a basic introduction to the procedures and gives examples of new applications, in particular in the automotive industry. PDF-Download

Positioning Complex Small Parts Securely

Metallform Wächter GmbH

In the optical industry, plasma processes are often used for the final cleaning of complex assemblies and small parts. The essential factors for producing successful results include ensuring that the parts are precisely positioned and, at the same time, keeping the surface area of the cleaning container to a minimum. To meet these requirements, special workpiece holders have been developed. PDF-Download

Rigorously Implemented

Rudolf Knott

Commercial vehicle manufacturer MAN will from now on be using a chrome (VI)-free coating from Dörken for the surface protection of high-strength steel fasteners. Its layered structure made up of a zinc flake coating with coordinated post-lubrication achieves the specified high level of corrosion resistance and at the same time fulfils the coefficient of friction requirements.
