Test methods
Bars in the automotive industry require special properties and machining. We offer these in a variety of materials with the tightest tolerances.
The bars undergo multiple eddy-current tests and, if required, can also be ultrasonically tested using the latest technology. Steel bars are used in a variety of automotive components.
Our wear and corrosion resistant powder metallurgical tool steels are often used in the demanding food and pharmaceutical industries. They are used for the manufacture of tableting tools, knives and blades used within the packaging of food, and the processing of packaging materials.
Bars with an optimized surface for piston rods in pneumatic cylinders are used in machine and plant engineering. The same applies to soft magnetic steels for solenoid valves. Choose from our wide range of materials. Due to the diverse production options, Zapp products have numerous applications in pneumatics.
