Bimetallic Twin Screw And Barrel For Plastic Recycling Agricultural Making Extrusion Machine

Bimetallic Twin Screw and Barrel for Plastic Recycling Agricultural Making Extrusion Machine

Product  Description:

Bloom manufacture screw elements,barrels and other extruder machinesWe have provided machines with matching screw and barrel, such as engel (Engel), davis-standard (Davis standard), weber (Weber), berstorff (Berstorff), Battenfeld, Cincinnati, Taiwan Zhuyou, South Nanrong, Zhende, Haitian, Haitai, Hangzhou Tairui, Chenhsong, Korea Woojin, Japan Sumitomo, sumida, Liansu, Hongqi, Jugang, Yuanfeng, Xiongsu, etc. Domestic and foreign plastic machinery companies.

Conical twin-screw extruder is an efficient mixing and extrusion equipment. The machine has the characteristics of low shear rate, difficult material decomposition, uniform plasticizing and mixing, stable quality, high output, wide application range and long service life.

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.

Material
1)Base material of bimetallic barrel:45# 40Cr
2)Bimetallic type:centrifugal casting
3)Application: for injection molding machine and extruder
4)Products range: Inner diameter ø12- ø350mm
5)Effective length: 12000mm
6)Nitrided layer thickness: 0.50-0.80mm
7)Hardness: HV960
8)Straightness: 0.015mm/m
9)Suitable plastic material: PP, PE, ABS, AS, PS etc.

For our bimetallic screw ,we have adopted a new technology of surface hardening process by the whole screw surface insted of only hard facing the screw flights by PTA treatment.

For bimetallic barrel ,we have raised its tungsten car-bide content to 30%and 50% from the previous 10% of tungsten carbide and increased the processing length to 4000mm from the previous length of 3000mmm
