The most difficult problem to solve in the design and production of plastic parts injection molding is the warpage.
Causes:
(1)Mold structure: pouring, cooling system and ejection system
(2) Product structure: plastic parts wall thickness changes, with curved or asymmetrical geometry, ribs and BOSS column design is not reasonable
(3) Production process: the plastic parts are not fully cooled, and the injection and pressure holding curves are unreasonable
(4) Plastic materials: plastic materials have, no added fillers, and the size of the shrinkage is.
Remedies:
(1) The mold temperature is unstable. Provide cooling/heating balanced mold
(2) Irregular section thickness Redesigned product shape and size according to resin characteristics
