heat sink insulated thin silicon nitride ceramic substrate 

heat sink insulated ultra thin silicon nitride ceramic sheet substrate 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 in…
