Comprehensive knowledge of the properties and the process parameters in polymer-extrusion together with the rheologic data of the melt are necessary to analyse and correct the design of the flow-channel with simulations using a CAE software. These simulations are the key factor of design for high-quality extrusion-dies. In addition, relies GMA on the many years of experience of the engineers in design of co-extrusion adapters and multichannel extrusion-dies.

Besides excellent design steel quality and chrome plating is very important for the quality of extrusion dies. GMA manufactures the extrusion dies and feedblocks with European steel.
