Detailed Product Description

38CrMoALA Nitriding Conical Twin Double Screw And Barrel / Twin Conical Screws And Cylinder For PP

1 . Description

We are the manufacturer of supplier of screw and barrel in china,including designing,manufacturing and sales for these products,we can make any specification of extruder screw barrel and injection molding screw barrel for Engle,Nigrobossi,KMD,NPM,BOY,Haitian,Demag,HUSKY, Nippon Steel, Toshiba, Nissei,Mitsubishi and etc. We also can supply all types of screw and barrel according to your different requirements.

Main Charactors:

Using machining center finishing, reasonable processing technology, advanced testing equipment, to ensure that the processing accuracy of each product.
Twin-screw extruder screw element:
- convenient interchangeability by agile combination.
- fulfill efficient self-cleaning, transmission, compounding, pressure-forming and etc.
- made of high speed tool steel W6Mo5Cr4V2, or anti-corrosion steel 38CrMoAlA by speed treatment.
The flexible modular principle is realized with screw barrel sections from the wide range of different designs possible. Fast, intensive and uniform heating of the screw barrel section is ensured by electrical heaters. The barrel sections are cooled with water by means of an internal bore system with bores arranged close to the inside barrel wall.

Screw diameter:Φ15mm-Φ360mmL/D=15-56

Length of screw and barrel/cylinder:8000mm

According to different material and plastic products to design different screw structure ,compress rate and L/D.
According to different material and plastic products to design different Barrel with exhaust system and IKV force load system.

The cross-sectional area is changed by adjusting the flight lead and thread depth, effectively eliminating sudden cross-sectional deformation and impeding resin pooling and extrusion fluctuations. Our (Barrier Mixer) with its high rolling and chaos effects can be mounted on the barrier outlet and screw tip to further enhance kneading and output rate.

3 . Comparsion of the output (LDPE)

Pressure is generated if resin passes over the barrier, forcing any air in the melted resin back to the feed side and effectively preventing the intrusion of air bubbles on the sub flight side. This is highly effective with resins that generate bubbles such as PS, PA, PET and EVOH.

4 . Material & Processes of screw barrel for plastic extruder

Alloy-steel of High-quality
1)38CrMoAlA
