Deformation of products of injection molding processing enterprises is a relatively common and difficult problem. Through analysis, we want to solve our social problems. From the perspective of machine adjustment, the feasibility is actually not great. The problem of deformation must be solved from the mold structure design management. The reasons for the specific deformation and the teaching methods for solving are as follows :
The main findings are as follows:
1. When the injection molding conditions cause deformation, reduce the stress by reducing the injection pressure, increasing the mold temperature, making the mold temperature uniform, increasing the resin temperature or using annealing methods.
2. When the bad behavior of demolding causes stress to deform, you can continuously increase the number or area of the push rods, and correct the demolding slope.
3. When the cooling is uneven or the cooling time is insufficient, adjust the cooling method to extend the cooling time. Setting the cooling circuit as close to the deformation as possible can also improve the deformation problem.
4. Due to the deformation caused by molding shrinkage, it is necessary to modify the mold design. Among them, the most important thing is to pay attention to making the product wall thickness consistent. Sometimes, if necessary, the mold must adjust the opposite direction by measuring the deformation of the part.
The above are the four major countermeasures to solve product distortion, have you learned? I hope to help you, and there will be more consultations in the future, and interested friends can pay more attention. deformation solution in injection molds
