38CrMoAlA Conical Twin Screw Barrel with HV900-1000 Hardness for PVC WPC Profile

Product Description:

Bloom manufacture screw elements,barrels and other extruder machines. We 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.

The main products are precision screw barrels (nitrided screw barrels, double alloy screw barrels, stainless steel screw barrels, fully hardened screws, high-speed tool steel screw barrels): injection molding machine screw barrels, extruder screw barrels, Blow molding machine screw barrel, chemical fiber machine screw barrel, single screw barrel, parallel twin screw barrel, conical twin screw barrel, screw barrel accessories;...

The products are made of high-quality 38crmoala; high-quality sacm645; high-quality skd11; high-quality skd61; 9cr18mov and other high-quality materials, which are tempered and formed. The surface can be nitrided, hard-plated, spray-welded hard alloy and other processes. The product has the advantages of high wear resistance, corrosion resistance and long service life. Widely applicable to various rubber and plastic raw materials, such as: pe, pp, pvc, ps, abs, pa, pom, pc, psv, ptfe, pvr, pr, up, pec, pf, vf, mp, pmma, pet, pbt , pps, mppo, pi, lcp, etc.
