The Consideration of 2K Injection Molding

The Consideration of 2K Injection Molding

The Advantage of 2K Injection Molding

• Stable production processes and high efficiency

• Lower part cost compared with overmolding and assembly parts

• Enhanced tactile and cosmetic product features

• High precision and stable part quality

• Improve the touch feel

• Expanded design possibilities

• Optimum bonding with minimum time and labor

2K 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

Variations of two shot moulding

There are a few variations of two shot moulding, including rotary platen, movable core, and overmold. The first two require a second injection unit, two runner systems, and two processes. The latter, in most cases, involves two separate molds—one for each material—but can also be run with one mold, two runner systems, and pick-and-place part transfer, either manually or with a robot.

Disadvantage of 2K Injection Molding

• 2K injection mold and 2K injection molding process cost is higher than single injection molding, but the cost can be covered because of the assembly cost.

• The combination between 2 plastic materials must be good
