The plate extrusion must be perfectly coordinated however, so that these benefits can be taken in advantage. Precise systems with a uniform material allowance should be used especially, to reduce cost and to ensure best quality. The fluctuations in bulk density, the edge incision, the quick and precise change of additives have to be considered.
The start-up times and number of rejects are also considerably reduced by using a technically sophisticated gravimetric dosing. In the extrusion of foam plates as well as in the production of compact plates.
