Key Points for Thin-Wall Product Mold Design
The design of thin-wall product molds requires considering many factors to ensure product quality and production efficiency. Here are some important design points:
1. Product Structure Design
Product shape should be as simple as possible, avoiding complex structures such as undercuts and through holes.
Product wall thickness should be uniform and consistent, avoiding local thinning or thickening.
The product surface should be as smooth as possible, avoiding bumps, sharp corners, etc.
Consider designing vents and vent holes in the product structure to facilitate venting.
2. Mold Structure Design
Mold steel should be selected from materials with high hardness, high strength, high toughness, and good wear resistance, such as S136, 2344, SKD61, etc.
The surfaces of the mold cavity and core should be smooth flat, and polished.
The sprue system of the mold should be designed reasonably to ensure that the molten plastic can fill the cavity smoothly.
The cooling system of the mold should be designed reasonably to ensure that the product can be cooled evenly.
The exhaust system of the mold should be designed reasonably to ensure that the air in the mold can be discharged in time.
3. Process Parameter Design
Injection pressure should be selected reasonably according to factors such as product wall thickness and material properties.
Injection speed should be selected reasonably according to factors such as product structure and material fluidity.
Holding pressure should be selected reasonably according to factors such as product wall thickness and material properties.
Mold temperature should be selected reasonably according to factors such as material properties.
4. Other Considerations
When designing thin-wall product molds, fully consider the product's usage requirements and conduct necessary simulation analysis.
When processing thin-wall product molds, strictly control the processing accuracy to ensure the quality of the mold.
When using thin-wall product molds, strictly follow the operating procedures and perform regular maintenance.
