The two-color injection molding industry in my country is developing rapidly and is currently popular in the market. The two-color injection molding process can make the appearance of the product more beautiful, easy to change the color without spraying, but it is expensive and requires high technical requirements. However, the matching materials for two-color injection molding must meet two basic compatibility conditions, adhesion compatibility and processing compatibility. In addition, the following requirements must also be met:
1. The injection unit, parallel and opposite, parallel opposite, horizontal and vertical L-shaped, Y-shaped single-cylinder injection structure.
2. Clamping mold, standard type, vertical turntable type, horizontal turntable type, shaft type, manipulator rotation type and other mechanisms.
3. Feeding, in addition to the standard hydraulic motor drive, there is also an ESD (ElectricScrewDrive) electric feeding structure.
4. Mixed nozzles, special nozzles such as patterns, waves, flow marks, gradients, and interlayers.
5. The oil circuit has ACC accumulator high-speed injection and closed circuit design.
Let me share with you what requirements the two-color injection molding materials must meet. The two-color injection molding achieves high response, high repeatability, and improved speed stability; using two raw materials or two colors can be molded at the same time, which greatly reduces the process and manpower. Realize cost saving; parameter setting and system adjustment are very simple digital operations.
