* Residual stress in plastics parts


The reasons for residual deformation are generally observed as detailed below:

(1) Deformation due to flow speed of resin in the cavity or uneven flowing speed

(2) Deformation due to indentation pressure

(3) Heat deformation due to huge temperature gap between cavity and core

(4) Deformation due to uneven cooling speed caused by shape or irregular thickness

(5) Mechanical deformation due to ejector pin or ejection problems
