Warpage deformation of PLA injection molded products
Problem Phenomenon
The product warps severely after demolding.
Cause Analysis
Uneven crystallization shrinkage and asymmetric molecular orientation of PLA cause warpage, and uneven mold temperature aggravates the problem.
Solution
Optimize the mold temperature uniformity; design the product with uniform wall thickness; optimize the gate position.
Key Takeaway
PLA warpage is the result of uneven shrinkage.
