Reputation depends on quality,  quality comes from Hard!

Silicon Nitride Ceramic:

The temperature of the nozzle is usually slightly Molded Tablets Focusing Potentiometer Ceramic Substrate lower than the maximum temperature of the barrel. This is to prevent the “salivation phenomenon” that may occur in the straight-through nozzle. The temperature of the nozzle should not be too low, otherwise it will cause the premature solidification of the melt and block the nozzle, or the performance of the product will be affected due to the premature solidification of the material injected into the cavity. Mold temperature has a great influence on the internal performance and apparent quality of the product. The mold temperature depends on the crystallinity of the plastic, the size and structure of the product, performance requirements, and other process conditions (melt temperature, injection speed and injection pressure, molding cycle, etc.). The Molded Tablets Focusing Potentiometer Ceramic Substrate pressure in the injection molding process includes plasticizing pressure and injection pressure, and directly affects the plasticization of plastics and product quality. Plasticizing pressure: (back pressure) When a screw injection machine is used, the pressure on the top of the screw when the screw is turned back is called plasticizing pressure, also known as back pressure. The size of this pressure can be adjusted by the overflow valve in the hydraulic system. During injection, the size of the plasticizing pressure is constant with the screw speed. When the plasticizing pressure is increased, the temperature of the melt will be increased, but the speed of the plasticizing will be reduced. In addition, increasing the plasticizing pressure can often Molded Tablets Focusing Potentiometer Ceramic Substrate make the temperature of the melt uniform, the mixing of the pigments and the discharge of the gas in the melt. In general operation, the decision of plasticizing pressure should be as low as possible under the premise of ensuring the quality of the product. The specific value varies with the type of plastic used, but usually rarely exceeds 20㎏/c㎡.
