1. Bottleneck of traditional injection molding
a. The injection pressure cannot be effectively transmitted continuously - the injection pressure is high, so
- Uneven pressure distribution
-Warping problem
-Multiple glue ports to solve the pressure drop problem (three-plate mold design)
b. Shrinkage problem - the thickness of the product must be uniform and there cannot be local thickness design.
- Uneven shrinkage
-Shrinkage issues
- Complex rib structure
2. Advantages of gas-assisted design
a. The injection pressure has penetrated into the finished product, so the pressure can be effectively transmitted
-Uniform injection pressure
-More uniform residual stress
- Smaller deformation
- Fewer glue points
-Effectively solve the problem of pressure shadow (external air molding)
-Effectively reduce the joint line (external air forming)
3. Types of gas-assisted
-Short shot molding: suitable for thicker finished products
-Full injection molding: suitable for 3C thin shell products
-PEP: Suitable for finished products with multiple cavities and shapes
-External air molding: suitable for finished products and thin shell finished products that require beautiful appearance
4. Energy saving
During the injection molding stage, the stage of holding pressure of the injection molding machine is usually the period of greatest power consumption. However, due to the introduction of gas-assisted injection, the injection holding pressure is replaced by gas, which can save a lot of power.
