Parallel twin screw barrel for twin-screw extruder machine

Application:
For the production of pipes, profiles, sheets, such as SPC floor, PVC wall board, PVC wood plastic, PE wood plastic, high molecular sheet, baking-free brick plate, high calcium plate, high calcium pipes, high calcium profiles, soft PVC sheet, PVC foam board, PP, PE, ABS, PVC, granulation and etc.

Specification:
Screw diameter: Φ45mm-Φ200mm, L/D ratio from 16-45.
we can produce twin parallel screw and barrel for all brand extrusion, experienced engineer can be sent to your factory for measuremnt.

Quality:
1: Nitriding quality------ base material: 38CrMoAlA(JIS SACM645)
2: Bimetallic quality-----Good abrasive& corrosive resistance.

Heat treatment:
Advance hardening and tempering
Nitriding treatment

Advantages of bimetallic parallel twin screw barrel:
1.Advanced nitriding technology
2.Duplex alloy spraying technology
3.High corrosion&abrasion resistance to prolong lifetime of screw and barrel
4.We use special alloy powders being sprayed and welded on the screw's ridge/flight,and use different alloy and welding methods for the screw of different functions.
5.For good plasticizing , it has many designs to meet customers' demand . Such as granual type , mutant type , wave type , barrier type , double screen typr ,shunt type , separation type , exhaust type and so on .
