What is the wear protection for screws and barrels?
The standard wear protection for all EJK screws is provided by the optimized screw design and the special nitration of the steel surface. For applications with, for example, rice husks, wood flour, glass fibre additives or barium sulphites as filler, EJK offers wear protection with a tungsten carbide coating on all surfaces in contact with the product. For the US market we supply a special tungsten carbide coating in PTA on the running surface of the screws. These screws are only suitable for use in bimetallic cylinders (X-800 cylinders).
What about warranty?

Can EJK provide references?
EJK could give references, but does not do so. We protect our customers with complete confidentiality and respect for all information we receive. We not only discuss machines, but also optimise recipes and products.

What is the other way of thinking at EJK?
A core part of our thinking is environmental protection. The EJK philosophy puts the customer in the foreground, but directly next to it, the environmental aspect. For example, we reduce the number of sales flights and trips to a minimum.
Does EJK have experience with WPC?
Several of our process units are the heart of extruders for the production of profiles with wood flour additives or natural fibres. In addition, our screws and barrels can be found in many areas of WPC pelletizing.
