How to deal with the deformation of plastic injection products
2023-12-20
The deformation of injection molded products may exist in the following situations. According to the situation, we give the corresponding handling suggestions as follows: 
1. The plastic injection molding process of raw materials is not even, the feed is too full or too little - adjust the screw backward position to reduce the feed 2. The gate position of the plastic injection mould is not good, asymmetry or insufficient number - change the gate or control the flow rate at the gate 3. Mold strength of the mould is not enough, easy to deformation, accuracy is not enough or wear or positioning is unreliable or improper ejection position - modification 4. The demoulding system of the plastic injection mold is not designed or installed well, and the force is not uniform during demoulding -- modification 
5. During the injection molding process, the material temperature of the plastic is too low, the mold temperature is low, the nozzle aperture is small, the injection pressure and speed are high, the shear stress is large - heating, reducing pressure, slowing down, reducing pressure 6. Uneven thickness of injection products, improper adjustment of parameters, uneven cooling or contraction - check whether the mold is heated evenly, or repair or adjust parameters In addition, there may be uneven mold temperature during injection molding, uneven cooling, slow cooling of thick wall part, fast cooling of thin wall part, or fast cooling of convex part of plastic parts, slow cooling of concave part, cooling time parameter setting is too short during injection molding, release product deformation, poor post-processing or preservation, self-adjustment.
