batte pvc extrusion mould pvc sheet dies
pvc extrusion mould/ pvc sheet dies
· Adopting high-quality alloy steel,coat-hanger flow channel and unique design of restrictor-bar without dead corner, effectively overcome the corrosivity of PVC. It can be co-extruded through feed block to get perfect composite foamed board.
· Special design for the flow channel and die lip, suitable for different types of foamed materials.
· Die lip temperature control unit, ensures to get foamed board with different foam rates.
· Can produce co-extruded foamed board,with rigid surface layer and foamed inner layer.
