What this machine can do?
Just put the raw material grain into the Funnel.and via the machine heat and water cooling,then produce the plastic sheet.
PET sheet extrusion machine:
Processing material: PET virgin pellets(APET or PETG) plus flakes; Or 100% flakes
Thicknes range: 0.15-1.5mm
Net sheet width: 650-1550mm(or as per cusotmer's requirement)
Layer structure: Signle layer or multi-layer
Capacity: 500-700kg/h
Application: Thermoforming(cup, bowel, etc. ), food box, fruit/egg tray, cup, electric tray, stationery, printing sheet, packaging, etc.
Production:
plastic sheet material extruder is composed of extruder,net transducer,die head,calender roller,takein machine,electric controller etc.The operational principle of the unit is as below:According to the tristate change of thermoplastic under different temperatures and take advantage of screw’s push effect,turning physical appearance into high pellet state,and then transform into plastic liquid.After flowing from the mould,then wind in received volumes via pressure-ray cooling stereotypes.The main fratures of this crew as below:feed cylinder,screw and mould are made of high quality alloy structure with the nitrogen.It has high hardnenss,corrosion protection,and long use span.The frame head adopts racks of guns and over.The flowing channel is suitable for the fluxion of liquid,non stagnation phenomena,the thickness of products are homogeneous,the pressure-ray roller adopts big screw shafts.It has excellent effect of adopting water cycle to cool,the temperature of feed cylinder and mould head are controlled by controller separately.The rotational speed of screw,pressure-ray machine rotational speed,rotational speed of received volumes can be adjusted respectively to ensure the speed of the whole set synchronous.
This machine is applicable to the production of PP, PE ,PS,environmental protection biological degradation plastic sheet etc.It is widely used for forming of plastic sheet,packaging products,office supplies,antiseptic adhesive tape such as packaging boxes,cup,bowl,salver and so on.
