Product deforms on demolding or dimensions unstable
Problem Phenomenon
The product deforms on demolding or dimensions unstable, related to the cooling time setting
Cause Analysis
Cooling time insufficient, product not fully solidified, deformation on demolding
Cooling time too long, low production efficiency
Uneven cooling, large differences in cooling rates at various parts
Unreasonable cooling water channel design
Cooling water temperature too high, low cooling efficiency
Solution
Reasonably set cooling time according to cellulose acetate butyrate and wall thickness
Optimize cooling water channels to ensure uniformity
Control cooling water temperature at 15-25°C
Extend cooling time at thick-walled parts
Avoid too short cooling causing deformation
Key Takeaway
Cooling time needs to be reasonably set according to material and wall thickness
