Double colorinjection molding technology has for many years, but has been in many problemsin the application of large injection molding products. Bandung, with years ofexperience in injection mold manufacturing, product production as thefoundation of technology, organization of the company's research anddevelopment team, break through the double color injection molding technologyin the application of large plastic products problems. Developed a 19 inch - 32inch of two-color injection TV shell, and successfully apply large plasticdouble color promotion in air conditioners, refrigerators, cars and otherproducts. At present, the company has Taiwan prosperous xin 1420 tons doublecolor large rotary injection molding machine equipment, can deal with all kindsof large double color mould production and equipment support.

Double shot molding mainly double color molding machine two tube with two sets of moulds according to the order made after two forming double color products. Compared with the traditional injection molding, the double shot of injection molding process has the following advantages:plastics to reduce weight.1. The core material can use low viscosity materials to reduce the injection pressure2. From the environmental consideration, core can use recycling secondary material.3. According to the different use of features, such as the cortex thickness unit is expected to use soft material, core core use hard material or material can use foamed plastics to reduce weight.4) can use lower quality of core materials to reduce costs.5. The cortex or core material can use expensive and special surface properties, such as preventing electromagnetic interference and high conductivity materials in order to increase product performance.6. The cortex and core material with appropriate can reduce residual stress and increase the mechanical strength moulded part or product surface properties.7. Products such as marble grain.

The advantage of double color molding products are as follows:1. Products with high precision and stable quality.2. Good structural strength, excellent durability.3. Cooperate with small gap, good appearance.4. Greatly reduces the cost.
