The technology is relatively mature compared with the traditional over-molding tech, double color can be injected at the same time, high efficiency and good stability, this  technology can be applied to a variety of products.

Multi-component molding is an efficient and cost effective technology for molding custom plastic parts with two or three plastic resins or colors in a single operation, and at faster cycle time and flash free.

ASM has mastered this technology and has manufactured parts using multi-component molding process for many years. With 4 sets 2K injection machines in house, and with our leading 2K technology, we are capable of manufacturing different types of 2K molds.

2. Good quality stability: the two molding steps can be done in one cavity and it can avoid part warpage issue during the mold open and part transfer. It is more stable than over-molding method.

4. Mold rotates on horizontal turn table, which is more stable than vertical rotation and has no inclination. It helps for life of mold, especially large molds.

1. Use robot arm to switch the molding part instead of rotary table method, it will be helpful to save investment cost of equipment.

2. With rotation core method, it can realize the various injection of material / color. Especially for small product, it will be more controllable on part dimension than rotary table method.

2. The disadvantage is that the injection molding of product #1 and product #2 cannot be injected at the same time, resulting in loss of efficiency.

1. Production in same machine with double time of cavities compared with normal mold. It can increase production efficiency.

Successful micro tooling is just a halfway. We use variothermal and vacuum molding to overcome polymer melt flow hesitation

When there is more deviation in the measurement than in the actual molded part, quality control is even more challenging.

1. Cost efficiency, it reduced core side compare with transfer method, but it still can achieve the 2k injection process in one mold.
