Battenfeld Injection Molding has moved to the testing phase on its four-year project to develop a ceramic screw.
The idea was recently awarded a prize in the Germany state of Hesse’s Technology Transfer Network (TTN).
The screws are designed for processing very abrasive materials, such as highly filled compounds. The project partners – which also include Aachen University and HC Starck Ceramics – have found new ways of producing metal-ceramic composites, and methods of joining them to metals.
“Ceramic screws will soon be ready for commercial production,” said the company.
The screws can also be used in extrusion equipment – and Extrusion for Ceramic Technology (ECT) is already building extruders using ceramic screws and barrels.
