WPC-Extrusion - KraussMaffei Berstorffcomplex expertise from a process tech- nology standpoint. What kinds of products are manufac- tured at the PinUFORM plant? Cascorbi: First, we use the residual pro- ducts from the wood production to pro- duce wpc pellets, which are suitable for all common technologies for additional processing such as extrusion, injection molding and compression molding. We, PinUFORM, see ourselves as devel- opers, not just as processors. Together with our customers we develop the pro-.

Wood Plastic Composite Foam Applications - Springer Linkreinforced polymer composites can be obtained by different processes (batch, injection molding, extrusion, and compression molding process) by using physical or chemical foaming agent. Matuana et al. [15] investigated the processing of microcellular-foamed structures in PVC/wood fiber (silane treated) composites by a batch-foaming pro- cess. They have established the relationships between cell morphology and processing conditions, as well as between the cell morphology and ...
