Production Design Plan
Twin Screw and Barrel
PVC powder granulation, do products(pvc pipe, profile,etc)
Some flat twin screws, according to the design can also do other plastic materials, such as: pe, pp
Application
01 Conical Twin Screw and Barrel
1. Nitrided screw and barrel:
Material: |
38CrMoAIA |
Surface hardness: |
≥HV900 |
Nitriding depth: |
0.5-0.8mm |
Conical twin screw and barrel types: |
φ45/97,φ51/105,φ55/110,φ60/125,φ80/156,φ92/188,φ95/191,φ105/216 |
2. Bimetallic screw and barrel:
Imported high-strength alloy steel material, the vulnerable parts of the screw are plasma surfacing, the thickness of the shackle base and the Ragi alloy is 1-1.5 mm, and the service life is increased by more than 1.5 times.
3.Conical twin screw and barrel types:
φ45/97,φ51/105,φ55/110,φ60/125,φ80/156,φ92/188,φ95/191,φ105/216
The material used for screw and barrel are subject to the demand of customers.
We can design the twin screw and barrel according to the customer's requirement
02 Parallel Twin Screw and Barrel
1. Nitrided screw and barrel:
Material |
38CrMoAIA |
Surface hardness: |
HV900 |
Nitriding depth: |
0.5-0.8mm |
Screw Diameter: |
φ45/2 -φ250/2 |
L/D ratio: |
16/40 |
2.Screw alloy material:
Basic material is 38CrMoAIA, bimetallic is welded on the screw flight, prolonging the life of the screw.
We Can Design The Twin Screw And Barrel According To The Customer's Requirements.

2. Fe-based alloy
3. Co-based alloy
4. NiCo-based alloy
5. Tungsten carbide
Specification: |
|
Screw diameter: |
φ10mm-φ350mm |
Screw maximal length: |
8000mm |
Barrel inner diameter: |
φ10mm-φ350mm |
Barrel maximal length: |
7000mm |
Advantages of bimetallic screw and barrel:
Wear-resisting,extending lifetime of screw and barrel.especially aiming at recycle material,raw material compound high percents calcium powder,30% glass fiber,the effects are perfect.Different bimetallic alloy materials are available for different raw material.
