ASA product warpage deformation
Problem Phenomenon
ASA flat plate and box-shaped products warp after demolding, assembly gaps are uneven, and deformation direction changes after adjusting holding pressure and cooling but is not eliminated.
Cause Analysis
ASA warpage originates from the combined effect of uneven cooling, orientation stress and structural asymmetry; front-rear mold temperature difference and water channel layout determine the temperature field; gate position affects the orientation stress distribution pattern.
Solution
①Independent temperature control of front and rear molds for targeted compensation; ②balanced cooling water channel modification; ③gate position optimization for symmetric orientation; ④structural reinforcing rib design suppresses deformation; ⑤mold flow analysis verifies the scheme.
Key Takeaway
ASA warpage treatment requires simultaneous efforts on temperature, structure and gate; independent temperature control compensation is a quick-acting means; mold flow analysis predicts deformation trends in advance.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
