Single Thread Screw:
Screws are specially designed with different compression ratios for different end products.
Products : PVC Film (Soft/Rigid/Shrink), PVC Profile (For wood pattern), Compounds (All kinds of compounds), Injection Molding Screws.
Vented Screw
It is best suitable for recycling of PP /HD / LD /HIPS /PC /ABS and other engineering compounds. The screw is designed for maximum efficiency and maximum mixing in conveying of the material with negligible heat. It is used for degassing of moisture and volatile through vent.
Mallifer:
Mallifer original Nokia design for high output & better mixing for cables.
Bimetallic Screw & Barrel:
Bimetallic layer on surface on screw and barrel gives high wear resistance to abrasive material. This results in long life period of screw and barrel. The maximum layer of bimetallic can go up to 6 mm. It is highly beneficial for manufacturers using high filled compounds such as calcium carbonate, glass filled.
ShengLong Machinery can supply almost any size of Extrusion Screw for almost any application and also offer a comprehensive rebuilding service too.
Just remember the most important element in any Extrusion system is the Feed Screw and is responsible for the critical functions of feeding, solid conveying, melting, mixing and pumping.
