Standard screw elements and barrels
Twin screw barrel is gradually adopted by many manufacturers
because of its high efficiency. Compared with single screw barrel,
twin screw barrel has higher requirements for machining clearance.
Our company has a professional team to help users solve design
problems, and can also process according to the samples or drawings
provided by customers.
injection screw barrel and bimetallic injection screw and barrel by
materials 38CrMoAlA or 42CrMo and so on,for many type of injection

Types of Barrels
Standard for classification: Design geometry Standard for classification: With inner or not
* Feeding barrel * Solid barrel
* Closed barrel * Barrels with inners
* Vent barrel
* Combi barrel
* Extended degassing barrel
* Combi barrel with backward venting
We offer a broader choice of materials:
Solid barrels
*Nitrided steel barrels *Tooling steel barrels *Bimetallic
Barrel with installed inner
* made of PM-HIP solid *WR13
By working closely with customers in choosing optional materials,we
can minimize wear and tear and associated costs.
