In the field of injection molding processing, product deformation is a widespread and complex issue. After deep analysis, we find that relying solely on adjusting equipment is not enough to completely solve the problem. The key to deformation lies in the formulation and supervision of mould design. The following is a summary of the actual causes of deformation and corresponding solutions:

Key Research Findings Overview:

1. Deformation Caused by Injection Molding Standards:

• Solution: Reduce injection pressure, increase the ambient temperature for medical mould injection, ensure uniform mould temperature, raise the epoxy resin temperature, or use annealing methods to effectively reduce stress and solve the deformation problem.

2. Deformation Induced by Improper Demoulding Behavior:

• Solution: Increase the number or area of ejector pins, adjust the demoulding slope, etc., to optimize the demoulding process and reduce deformation caused by improper demoulding.

3. Deformation Due to Uneven Cooling or Insufficient Cooling Time:

• Solution: Adjust the cooling method, increase the cooling time, and try to set the cooling circuit close to the deformation area to improve the deformation problem.

4. Deformation Caused by Molding Shrinkage:

• Solution: Modifications to the medical mould injection are required, especially to ensure consistent thickness of the equipment. When necessary, the mould must be adjusted in the opposite direction based on precise measurements of part deformation.

The deformation problem in medical mold injection molding is a result of the joint action of many factors. In order to solve this problem effectively, we need to start from the formulation and supervision of mold design, and adopt corresponding solution strategies for different types of deformation causes. By reducing the injection pressure, optimizing the process of mold release, adjusting the cooling method and changing the mold design, we can effectively reduce and avoid the deformation problem in medical mold injection molding, so as to improve the product quality and production efficiency.
