The NHTS series injection molding machine includes mixed color injection, sandwich injection, etc. It is composed of two independent injection units. It has a variety of injection modes to choose from. It has a unique barrel precursor and nozzle design. It can be injected separately or in sequence according to requirements. Simultaneous injection to meet different color mixing effect designs and sandwich injection requirements. It can be used for single-color production, or mixed production of plastics of different colors and transparency. At the same time, some products are injected with high-quality materials through the surface layer, and the core layer is injected with secondary recycled materials, which can reduce residual stress, increase product strength, and reduce production costs. The power is equipped with two sets of servo servo control systems, which can meet precision injection and reduce energy consumption.
