Warpage deformation of PLA injection molded products
Fenómeno do problema
The product warps severely after demolding.
Análise das causas
Uneven crystallization shrinkage and asymmetric molecular orientation of PLA cause warpage, and uneven mold temperature aggravates the problem.
Solução
Optimize the mold temperature uniformity; design the product with uniform wall thickness; optimize the gate position.
Conclusão principal
PLA warpage is the result of uneven shrinkage.
