1. Unreasonable mold design: The characteristics of thin-walled injection molded parts are not fully considered in the mold design, resulting in improper mold structure or gate design, which is easy to cause deformation of injection molded parts.

2. Improper mold temperature control: In the injection molding process, the mold temperature is too high or too low will affect the cooling and shrinkage of the injection molded parts, resulting in the deformation of the injection molded parts.

3. Improper control of injection pressure and speed: Improper control of injection pressure and speed will lead to uneven flow of plastic in the mold cavity, resulting in a decrease in the fluidity of the plastic melt, resulting in underfilling or overfilling, and eventually leading to the deformation of injection molded parts.

4. Improper material formulation: improper selection and treatment of plastic materials, such as improper formula components such as reinforcing agents and tougheners added to the materials, will affect the shrinkage and thermal performance of plastics, resulting in deformation of injection molded parts.

5. Improper post-processing: Improper post-processing of injection molded parts after cooling, such as heat treatment, correction, etc., will also affect the stability and deformation of injection molded parts.

6. The technical level of the operator is not high: the technical level of the operator is not high or the experience is insufficient, which is easy to cause operation errors or improper adjustment, which will affect the quality and deformation of the injection molded parts.

In order to reduce the deformation of thin-walled mold injection molded parts, improvements can be made in the following aspects: optimizing mold design, reasonably controlling mold temperature, optimizing injection process parameters, improving material formulation, adopting appropriate post-treatment processes, and improving the skill level of operators. At the same time, it is also necessary to continuously accumulate experience in the actual production process, strengthen the monitoring and quality management of the production process, and ensure the quality and stability of thin-walled mold injection molded parts.
