Biaxially Oriented Die

Suzhou Jwell precision machinery co., ltd. is a profession-al  T-die extrusion manufacturer. Specializing in the man-ufacturing of different kinds for sheet, plate, film, coating single-layer and multi-layer co-extrusion die series, Various kinds of  distributors, melt pumps and hydraulic screen changer, mirror roller etc, we devote ourselves work for plastic producer to provide the most value of the extrusion system; With the abundant manufacturing experience and continuously technical innovation, equipped with modern CNC processing machines,our company is making the products more perfect. Our prod-ucts widely used in PP, PE, PET, GPPS, HIPS, ABS, PC, PMMA, PVC, EVA, PVB etc  raw material production.

Each T-die manufactured by our company’s engineer that according to customer requirement. Our engineers coordinate with the customer to confirm the T-die design, material to be used, flow channel, temperature control. Thickness adjustment, witdh adjustment and other factors of the T-die.

"Excellent quality, perfect as one" is our company quality policy "Honesty and treat people" is JWELL's core concept. We will try to create more superior die series with high-quality, provide thoughtful services, to help custom-ers and cooperation partners to create more value.

Biaxially Oriented Die:

The die is crucial part of the biaxially oriented cast sheet, directly decided to cast sheet shape and thickness uniformity. This biaxially oriented casting sheet die adopt coat hanger flow channel design, and equip with professional computer fluid analysis software, Flow channel CFD analysis and optimization, to obtain the best fluid parameters. Die openings adjustment adopts the push-pull type automatic die lip adjustment，through online thickness gauge of the thickness of the detected data through computer program processing after feedback to the special die lip thermal expansion regulating bolts, for the opening of the die lip thickness automatic fine-tuning, effective control of product precision. This die applicable for: BOPP, BOPS, BOPA, BOPET,  BOPI products etc. 

The die lip straightness, roughness and the size of the lip sharp angle is direct impact on the quality of products. After experiments and repeated demonstration, using short-wave pulse local hardening treatment can be effective in improving the quality of the die. so that hardened surface hardness, microstructure refinement, wear resistance superior to conventional quenching process. The die lip straightness and abrasion resistance is better.
