高Volume Injection Molding Manufacturer

高容量设计部分

1. Transitions between wall thickness should be gradual to reduce flow problems, such as back fills and gas traps.
2. 深,unventable blind pockets or ribs should be avoided.
3. Long draws should have a 3-5° draft per side to aid component ejection.
4. The TPE thickness should be less than or equal to the thickness of the substrate to prevent warpage; this is especially critical for long, flat geometries.
5. Uniform wall thickness in product is preferred to obtain the best molding cycle time and avoid shrink mark. Wall thicknesses ranging from 1.5 mm-3 mm will ensure good bonding in most overmolding applications. If the part requires the use of thick TPE sections, they should be cored out to minimize shrinkage problems, reduce the part weight and lower cycle time.

高Volume Injection Mold Design

We insist mold construction design, steel quality and precise manufacturing is the key to achieve molds with excellent performance. Our mold design principle is the mold must be durable, high efficiency and easy to do the maintance and manufacturing.

1. Shrinkage factor for both materials.
2. Plastic component wall thickness, uniform wall thickness preferred.
3. Number of cavities in the mold
4. Plastic material feeding systems. Runner and Gate
5. Core and cavity cooling system
6. Component ejection system.
7. To avoiding burn mark, air vent is necessary.
8. Injection Molding Type
