Problem & Solution
Practical answers to common plastic material challenges
Compression molding is used to reduce warpage and internal stress but the parameters are set improperly
Large shrinkage difference between the melt flow direction and the perpendicular direction
Product partially not filled
Thin-wall products with wall thickness <1mm have many short shot, warpage and deformation problems
Thin flash appears at the parting line or moving parts of the product
Gas-assisted injection is used to reduce shrinkage and warpage but parameters are set improperly
Irregular deformation of the product after demolding
Linear marks appear around multiple gates or holes of the product
Glass fiber PA requires special process parameters to avoid floating fiber and property fluctuation
Front zone temperature directly affects the temperature and flowability of the melt entering the cavity
