BJM Mix-color Series

BJM Mix-color Series


POWERJET BJM series two-color special injection molding machine uses the first plastic injection molding. After the mold is opened, the entire moving mold and the workpiece are rotated by 180° from the turntable. After the mold cavity is aligned and the mold is closed, the second injection is performed for co-plastic molding; The first plastic injection and the second plastic injection are carried out simultaneously to produce two-color products with distinct colors.
 



Features:


·The machine has a turntable mechanism, suitable for the production of distinct two-color products;
·Turntable mechanical positioning, accurate and reliable;
·External mold oil and water distribution pipeline, easy to use and maintain;
·Hydraulic servo system, energy saving and environmental protection, high control accuracy;
·Optional turntable and shaft mechanism to realize the production of various products;
·Different ejection control methods;
·Two shots are controlled independently, which can realize simultaneous injection and shorten molding time.
·Two raw materials or two colors can be formed at the same time, greatly reducing the process and manpower to achieve cost savings;
·Parameter setting and system adjustment are very simple digital operations;
·High response, high repeatability, and improved speed stability;
