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.
