Thermoplastics:
Thermoplastics are used for the production of plastic parts for the electrical and car industry.

When injection moulding plastics with a filler rate of > 30 % it makes sense from the economical point of view to invest in cemented carbide extrusion sets.The high utilisation rate and the enhanced quality of the injection moulded products warrant the overall profitability of any investment in our tools.

High-temperature resistant Thermoplastics:
The high working temperatures may generate a thermal decomposition of the plastics. Plastic particles get stuck on the screw and penetrate into the plastic moulding material.
The result is impure products and a substantially higher scrap rate. Because of the higher thermal conductivity of cemented carbides, there is no accumulation of heat and consequently no breakdown of the extrusion set due to thermal cracks.

It is precisely this ability to maintain a high hardness in an extreme temperature working range which constitutes the essential advantage of our tools over the conventional steel tools.

Oxide Ceramics::
When injection moulding ceramic parts, abrasion causes a rapid wear of the extrusion tools. Compared with the average life of 700 h for steel tools, our cemented carbide tools have totaled a 50 times longer running time.

Problems such as the abrasion of metallic particles, their penetration into the ceramic moulding material, the ensuing impurity and pigmentation of the finished product – a common phenomenon with steel tools – could be eliminated by using cemented carbide tools.

Permanent Magnets:
The production of barium-, strontium- and rare earth-based magnets is subject to a heavy wear of the screws and the cylinders. Conventional steel extrusion sets were worn after 800–1000 hours of use in the entry zone, whereas our cemented carbide tools have totaled a running time of 23000 h since 1987.

Cemented Carbides:
When injection moulding cemented carbide
parts, cemented carbide extrusion sets have proved to be extremely efficient. Well-known cemented carbide producers have used our extrusion sets for years, whereas steel tools were no longer usable after 3–4 month running time.
