Push Pull Type Plastic Extrusion Line Biaxially Oriented Die For BOPP / BOPS
Descriptions :
This die applicable for BOPP, BOPS, BOPA, BOPET, BOPI products etc.
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.
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, micro-structure refinement, wear resistance superior t conventional quenching process. The die lip straightness and abrasion resistance is better.
We will provide you a whole set standard service with general maintenance, die clean, examination, repair, upgrade, renovate and so on. After renovates the die, it can achieve or very close to the initial standard. Every need to repair the die we will strictly according to the following steps :
Die remove, cleaning.
Inspection, evaluation and communicate with customer requirements for renovation.
Faded except the original chromium plating.
Repair damaged surface defects or change the defects in design.
Replace damaged parts.
Repairing mold body joints.
The mold flow channel to polish.
