Silicon Nitride Ceramic:

The processing temperature of the plastic is controlled by the barrel of the injection machine. The correct selection of the barrel temperature is related to the plasticization quality of the plastic. The principle is to ensure smooth injection molding without causing partial degradation of the plastic. Generally, the maximum temperature at the end of the barrel should be higher than the flow temperature (or melting temperature) of the plastic, but lower than the decomposition temperature of the plastic. In addition to strictly controlling the maximum temperature of the injection machine barrel during production, the residence time of the plastic melt in the barrel should also be controlled. When Laser Cutting Ceramics determining the barrel temperature, the structural characteristics of the product and mold should also be considered. When forming thin-walled or complex-shaped products, the flow resistance is large, and increasing the barrel temperature helps to improve the fluidity of the melt. In the injection molding process, the mold temperature is controlled by the cooling medium (usually water), which determines the cooling rate of the plastic melt. The lower the mold temperature, the faster the cooling rate, and the faster Laser Cutting Ceramics the melt temperature decreases, resulting in an increase in melt viscosity and injection pressure loss, which may even cause insufficient mold filling in severe cases. As the mold temperature increases, the melt fluidity increases, the required filling pressure decreases, and the surface quality of the product improves; but due to the increase in cooling time, the productivity of the product decreases and the molding shrinkage rate of the product increases. For crystalline plastics, since higher temperatures are conducive to crystallization, increasing the mold temperature can increase the density or structural crystallinity of the product. At higher mold temperatures, the relaxation process of polymer macromolecules in the product is faster, and the molecular orientation and internal stress will be reduced.
