The WPC granulate from the German company JELU has proven its optimal performance in comprehensive tests even in injection-moulding techniques. In the past, JELU has developed a process for manufacturing WPC granulate. JELU processes wood fibres, polypropylene and additives to manufacture a high-quality, homogenously compounded WPC mix using machines specifically designed for this purpose.
WPC for injection moulding and extrusion
The WPC granulate has already proven its optimal performance in panel pressing and extrusion techniques. With further tests, the company was now able to ensure that its WPC granulate can also be metered without difficulty in injection-moulding processes and that it is able to fully fill the injection moulds. The tests were performed using conventional injection-moulding machines for plastics. Hardened and corrosion-protected screws prevent the screw surface from abrasive wear.
The properties of the end product are determined by the quality and type of the ingredients. They can be customised by means of filler concentration and additives according to the application field:
- melting point
- tensile and flexural strength
- impact strength
- elongation at break
- weather resistance
- insect resistance
