1,PVC control foam board introduction:
PVC/PVC-WPC 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 formworkers.
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.
usually foam board size 4' wide, 8' length, 5-25mm thickness, also some client want MAX to 35mm, or 40mm thickness, it is ok to be manufactured.
raw material mixing--feeding---extrusion----forming and cooling----cooling---hauling--cutting
1. SRL-Z500/1000 hot-cooling mixer,
capacity 500-700KG/H, driven by 75KW XIMO motor adjust by ABB inverter.
self friction & electric heating for hot mixer, water cooling for cooling mixer.
tank wall made by 8mm thickness stainless steel.
2. conical double screw extruder with screw loader
Benk's conical double screw extruder equiped with parallel twin screw feeder, which can avoid the PVC powder material block.
Screw feeder equiped with limit switch, which used to guarantee the material loading equal and continously. or equip with vacuum loader, which can help solve PVC powder dust problem for client.
Making 5-25mm thickness free foam board, just need 80/156 conical double screw extruder,
Making 25-45mm thickness free foam board, need 92/188 conical twin screw extruder
Making 5-25mm thickness skinning foam board, need 80/156 extruder + 65/132 extruder
Making 25-45mm thickness skinning foam board, need 92/188 extruder + 80/156 extruder
3. extrusion and forming mould + calibration table + cooling bridge
extruder die adopt T type design, board thickness adjustable, 5-25mm thickness board just one set T-die, 25-45mm thickness foam board need another set T-die.
forming die(sizing die) up and down move by hydraulic, cooling by water, cycling cooling water.
4, eight-roller haul-off
8 group rubber hauling roller, driven by 5.5KW motor, guarantee enough powder for foam board proessing.
front of haul-off add an small device can give protect film lamianted on the board.
behind the haul-off, equiped 4 cutting saw, up two is fixed to cutting the not good side of the foam board, center distance 4'.
down two cutter moveable, used to division the foam board to samll wide when requred, like 2' + 2' .
used to cut the board into wanted length, usually 8'.
