Injection molding machine leakage can be divided into internal leakage and external leakage. Internal leakage means that a small amount of liquid inside the hydraulic component leaks from the high pressure cavity to the low pressure cavity. The greater the internal leakage, the greater the heat gene... read more
A.Temperature control 1. Barrel temperature: The temperature that needs to be controlled during the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The first two temperatures mainly affect the plasticization and flow of plastics, while the latter tempe... read more
1. General rules for safe production in injection molding workshop: 1. When the equipment is operating normally, it is strictly prohibited to touch any part of the equipment except the safety door and control panel in front of the injection molding machine. 2. The treatment of any abnormal productio... read more
The entry technology of injection molding machine adjustment: injection molding is an engineering technology that involves transforming plastics into useful products that can maintain their original performance. The important process conditions of injection molding are the temperature, pressure and ... read more
1. Clean the cartoning machine, not only lubricate the rolling bearing and other transmission systems, try to maintain it on time, add mechanical red oil when needed to keep the chain running 2. The cartoning machine prevents rusting, retesting treatment, waterproofing and other maintenance work. In... read more
Items to be checked when starting up the vertical injection molding machine: 1. Check of operating oil: determine whether the amount of operating oil of the vertical injection molding machine is between the low limit and the high limit of the oil gauge. Whether the amount of oil in the automatic lub... read more
An injection molding machine is a device that combines the thermal processing characteristics of plastics and the principle of molten die casting of metals. In the late 1940s, the pre-plasticized screw injection molding machine was developed. Since then, the development is mainly centered on the pre... read more
There are many plastic products factories that need to use chillers to cool the machines, but when many friends buy industrial chillers, they often don’t know what type of chillers to use to achieve the cooling effect they require, or say no Know what kind of machine is more suitable for your produc... read more
Even if I have been repairing hydraulic injection molding machines for many years and I am quite confident in maintenance technology, using the experience of repairing hydraulic injection molding machines in the past to repair all-electric injection molding machines will feel powerless when working.... read more
The requirements of injection molding machines for the production of small and light parts have made thin-wall injection molding machines the required performance for injection molding machines. "Thin wall" is generally defined by lightweight electronic device parts with a wall thickness of less tha... read more
High-speed production of vertical injection molding machines requires large thin-walled speeds; we need speed curves for thick-walled parts to avoid some defects; to ensure that the quality of the parts meets the standards, the injection speed should be set to keep the flow rate of the melt forward ... read more
As the plastic flows through different parts of the injection molding machine and the mold, due to the influence of resistance and friction, the pressure on the plastic flow front will be lost. In addition, as the plastic contacts the mold wall, it begins to cool, increasing the viscosity of the pla... read more
