DEYI Machinery Co.,Ltd.professional manufacturer of screw and barrel of key enterprises,the company is committed to:conical twin screw,parallel twin-screw,single-screw extruders,injection molding machines,rubber melt glue machine,fiber machine,Del foam extruder barrel screw------main components of professional production.Materials used 38CrMoALA steel,the quenching and tempering,qualitative, nitrogen,a polishing process,refined,with long life,wear resistance,good corrosion resistance,etc.,it can be used to replace foreign advanced equipment and Equipment domestic high-performance devices.

Technology Advantage

38CrMoAIA Screw and Barrel for Plastic Injection Molding

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 tool speed 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.
