Multi-Cavity Two-Color Bottle Cap Injection Mold
The matching materials for two-color injection molding must meet two basic compatibility conditions: adhesive compatibility and processing compatibility. In addition, the following requirements must be met:
(1) Injection unit, parallel in the same direction, parallel in the opposite direction, horizontal and vertical L-shaped, Y-shaped in the same direction single cylinder injection structure;
(2) Mixed nozzle, special nozzles with patterns, waves, flow marks, gradients, interlayers, etc;
(3) Clamping mold, standard type, vertical turntable type, horizontal turntable type, rotary shaft type, mechanical arm rotating type and other mechanisms;
(4) Feeding, in addition to standard hydraulic motor drive, there is also ESD (ElectricScrewDrive) electric feeding structure;
(5) Oil circuit, with ACC pressure storage high-speed injection and closed-loop design.

Two color injection molding
Two color injection molding is the process of using two types of plastics to inject a component.
Generalized two-color injection molding includes overmolding, which is achieved through two injection molding processes using a regular injection molding machine. Narrowly defined, two-color injection molding refers to the use of a two-color injection molding machine to inject two different plastics into a component on the same machine, commonly using a rotary type.
The former does not have high requirements for equipment, but has low production efficiency and is basically only suitable for molding materials that do not require high levels of soft or hard glue. The latter has good applicability and product quality, high production efficiency, and is currently the trend
Strong performance and high energy saving: After the energy-saving transformation of the injection molding machine, the system can respond quickly, and the injection molding machine can adjust the supply quickly according to its own needs, which can effectively improve the utilization rate of the injection molding machine's electrical energy and achieve high efficiency and energy saving.
Good stability: The system adopts dual closed-loop control of pressure and flow, which determines the supply of the injection molding machine according to its demand. The system can reach a new equilibrium state or return to its original equilibrium state after a brief adjustment process under given input or external interference.
Fast responsiveness: Fast responsiveness is one of the important indicators of the dynamic quality of servo systems. Due to the short production transition time, generally within 200ms, in order to achieve overshoot requirements, the front edge of the transition process is required to be steep, and the rise rate after energy-saving transformation should be large. The injection molding machine can reach 1500 revolutions per minute in less than 0.03 seconds.
