Custom Made CNC Lathe Milling Machining OEM Machining Extruder Barrel And Screw
Main parameters of screw and barrel:
||38 CrMoAlA(JIS SACM645); 42CrMo(JIS SCM440)
|Hardness of nitrogen treatment
||HV240 ° ~280°
|Depth of nitrogen layer:
||above 1 stage
|Hardess of surface chromium-plating after Nitriding
|Chromium plating Depth
||nitrogen ,electroplated hard -chrome finish,high frequency quenching
Remarks :We can design and manufacture various kinds of screw barrel according to the customers requirement.
1. Parallel twin screw and barrel has the advantage of lower rotation speed, smaller shear stress between the small screw
2. Good plasticization, high productivity, small shear force, stable pressure , less wear and tear and low cost.
3. Parallel twin-screw and barrel is widely used in PVC products processing, especially for the production of PVC products with the output over 350Kg / h, because the parallel twin-screw and barrel costs less than conical twin-screw and barrel while it has more mature technology.
4. Parallel twin-screw and barrel is successfully applied in PVC plate, pipe, profile, pellet and mould, at the same time, it solved the technical problem of low foaming, high foaming, high filling, wear and corrosion.
Q: What information should be provided when inquiry price of screw and barrel?
- Conical / parallel twin screw barrel
