· 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.
