Details about products
The extrusion lines consists of SJZ conical twin screw extruder and SJ single
screw extruder, equipped with corresponding MSYF-series profile auxiliary
accessories and moulds, the following products can be produced: PVC/PP/PE
plastic & wood profile, plastic & wood sheet, foamed profile, panel and others.
Specially designed screw, advanced and reasonable production process can protect
the filing stuff made of polyolefine, polyvinyl-chloride wood fiber or fiber
made of other cellulose from over-burning or color fading, and improving the
fluidity of the composite material, helping the wood fiber be dipped in plastics
well, making more equal mixture of wood fiber and plastics, therefore, operation
at relatively low temperature is feasible, which is good for the mould to
release the material and minimizes cracks of melted material and edge tearing
during forming the filling stuff of plastic & wood fiber composite material.
Performance and characteristics
1. Optimized high efficiency conical twin screw extruder and parallel twin screw
extruder are applicable to extrude PVC product with many kinds of prescription
of raw material. The advantages are compact structure, equal plasticity and
mixture, stable quality, wide application range, long service life, free of
maintenance for screw temperature control, low compression ratio, low speed &
high output, high rated torque, low maintenance cost, excellent quality and
2. The forced material feeding system is specially designed to match the twin
screw , so as to make sure stable high-speed plastic & wood product extrusion.
3. Strong and durable hard-surface drive system makes sure the stable pressing
amount and good quality.
4. The temperature system keeps stable output at different speed of the screws.
5. Automatic closed-loop control is realized via smart modular C4 control
6. For those customers who request screw & barrel and gearbox critically, the
European imported products are the reasonable option.
7. Vacuum calibrator table is designed on the basis of ultra-long quick cooling
technique; quick vacuum adjustment system assures the stable vacuum degree and
quick shaping of PVC/PP/PE plastic & wood profile and sheet.
8. The Haul-off is double driving mechanism, all the caterpillar bands are
driven separately by AC motors and controlled by digital controllers, which is
very important for accurate speed adjustment and removes the possibility of
slipping due to unequal driving force distribution, and therefore, the stability
of plastic & wood profile extrusion is gained.
9. Horizontal/vertical cutter and saw cutters are the options, which can be
controlled by PLC.
