1．what is thin wall mold
Thin-wall injection mold is a mold used to produce plastic products with a wall thickness less than 1mm.
Thin-wall injection molds are widely used in the following fields:
Electronic products: such as mobile phone cases, tablet cases, earphone cases, etc..
Auto Parts: Used to produce lightweight, high-strength automotive parts.
Medical Devices: Produces precision medical device components
2．what is thin wall parts
Thin-wall injection molding refers to designing the wall thickness of plastic parts to be thinner than conventional parts. Injection molding parts with a wall thickness less than 1mm are usually called thin-wall injection molding parts.
3．To make thin-walled products, how to choose an injection molding machine and how to design a mold?
When producing thin wall products, a high-speed injection molding machine should be used to ensure stable injection speed, cycle time and opening and closing mold structure.
a.Choose suitable materials.
When designing molds for thin-walled products, material selection is crucial. Compared with ordinary mold materials, thin-walled product molds require higher hardness and better wear resistance and thermal stability. Common mold materials include P20, H13, S7, etc. The specific selection needs to be analyzed based on the material, shape, size and other factors of the product.
b. suitable structure design:
The structural design of thin-walled product molds needs to consider factors such as appearance, process performance, and cost. In order to ensure the appearance and accuracy of the product, the mold needs to have complex structures, such as parting, secant lines, pushers, and sliders. At the same time, in order to improve production efficiency, the structure of the mold also needs to be as simple as possible.
c.Proper cooling system design:
The high-speed production of thin-walled product molds requires a good cooling system to ensure that the mold does not overheat and affect product quality.
4．The key point for thin wall Mold design
The mold is required to have good rigidity, strict control of product vibration and deformation, and the hot runner system needs to be coordinated to improve product quality.
Thick wall mold: You need to consider the shrinkage rate of the product, ensure the rigidity of the mold, control the mold temperature to avoid shrinkage and deformation of the product, and also ensure the fluidity and consistency of the plastic.
5．Difference in process between thin wall products and thick wall products
a. Production of thin wall products: It is necessary to reduce the injection pressure and time, increase the injection speed, and use cooling to increase the temperature to make the plastic temperature uniform to achieve lightweight products.
b. Production of thick wall products: It is necessary to extend the injection time, increase the injection pressure, keep the temperature stable, and ensure product volume and quality.
