PVC co-extruded foam board making machine /PVC co-extrusion foam sheet production line

PVC co-extruded foam board machine production line
PVC foam board can be used for furniture & construction function.
--used for furniture, it is free foam type. one extruder with T die is ok.
--used for construction, it is surface co-extruded with pure PVC,no foam, so surface is more stronger than free foam type, it is good used for concrete frameworkers. 
Free foam & surfacce co-extruder (also called skinning foam ) is there one more extruder and division connection part for die. others are same.  so it means you invest an skinning foam board line, it also can produce free foam type board.
