Descriptions
Twin screw barrel is gradually adopted by many manufacturers because of its high efficiency. Compared with single screw barrel, twin screw barrel has higher requirements for machining clearance. Our company has a professional team to help users solve design problems, and can also process according to the samples or drawings provided by customers.
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.
Bloom supplies cylinder barrel suitable for the following extruder products lines :
-APV -KOBE -OMC
-Buhler -KraussMaffei -Theysohn
-Buss -Berstorff- -Toshiba
