OEM Service for Bimetallic conical twin screw
1)Make the screw & barrel as per customers' drawings;
2)Provide engineers to your factory for measuring the old screw and
barrel, then make new one.
Our Bimetallic conical twin screw barrel is very popular with
domestic pvc foam board manufacturer. And also they are exported
along with plastic extruder machinery to other countries. It is our
honor to receive your message.
They are special used for different density of PVC products which
acquired through PVC material mix with certain proportion chemical
foam agent by certain recipe. They are widely used because the
products have low density and light weight. Such as advertisement
board, cabinet bath board in home decoration industry, floor,
building templates. The foam products are the ideal products
replaced wood for plastic.
Technical parameter for the conical twin screw barrel
We can make the machine by our drawings if you give me the
nameplate of the machine you use; Or we produce or according to
The material we adopt is 38CromoAIA, the nitride deepth is 0.5-0.7,
the quality guarantee period is 6 month. But according to our
customers' experiences, our products can be totally used in 12
Material of the screw barrel
Screw barrel adapt high quality 38Cromaia raw material and due to
different plastic material , screw barrel can spray bimetallic
treatment which with more long service life.
Surface Treatment--PTA Machine
The bimetallic treatment of our screw by the PTA machine. It is a
advance equipment which has not been broadly used in bimetallic
treatment. Compare to the manual process the advantage is better
temperature stability, dense structure and uniform thickness and
not liable to crack.
Centrufugal Barrel Bimetallic
The bimetallic barrel is centrifugally cast a 2~4mm thick alloy
coat on the output section of barrel inner wall which has excellent
corrosion resistance, abrasion resistance and high working
temperature. And its useful service life is greatly improved
contrast to the common nitrided barrel. Bimetal has more obvious
advantages when processing high calcium carbonate powder PVC
mixture to enhance the abrasion life.
The screw can be work for PVC UPVC pipe tube extrusion, for sheet
film extrusion and for profile extrusion.
The screw barrel will design according to customer demand like raw
material, final product and output.
plastic injection screw dapt high quality 38Cromaia raw material
and due to different plastic material , screw barrel can spray
bimetallic treatment which with more long service life.
1. Be brushed anti-corrosive oil on screw barrel.
2. Packed with film.
3. Packed in the wooden carton.
