Classification of injection molding machines

Do you know the types of injection molding machines? Injection molding machine is divided into the following five types: Vertical injection molding machine Features: Easy to achieve insert molding. Because the surface of the mold is facing up, the inserts are easily placed and positioned. The lower template is fixed and the upper template is movable. If the pull-belt conveying device is combined with the mechanical palm, the automatic insert molding can be easily realized. The weight of the mold is supported by the horizontal template for up and down opening and closing action, will not occur similar to the horizontal machine due to the mold gravity caused by the forward fall, so that the template can not open and close the phenomenon.

How to Control the Injection Pressure of Injection Molding

All movements in the injection molding process, whether hydraulic or electric, generate injection pressure. Appropriate control of the required injection molding pressure produces a great product with good quality. The injection pressure regulation and metering system is on the hydraulic injection molding machine, and all movements are performed by the oil circuit responsible for the following operations: 1. Screw rotation in the plasticizing stage. 2. Slider feeder (the nozzle is close to the nozzle bushing). 3. Axial movement of the injection screw during injection and pressure holding. 4. Close the base material on the injection rod until the toggle rod is fully extended or the piston mold clamping stroke is completed. 5. Start the ejection table of the assembly ejector to eject the components. On full electric injection
