At the same time of high efficiency production, the most important thing for mold manufacturers is how to ensure the quality. Mold processing is an enterprise with strict requirements on technology and equipment. It is very suitable to use it here. Therefore, enterprises should strictly control technology and do a good job in management.

First: reasonably use the cooling lubricating liquid, play the three functions of cooling, washing and lubrication, keep the cooling lubrication clean, so as to control the grinding heat within the allowable range, and prevent the workpiece from thermal deformation. To improve the cooling conditions of grinding, such as the use of immersion grinding wheel or internal cooling grinding wheel and other measures. By introducing cutting fluid into the center of grinding wheel, cutting fluid can directly enter the grinding area, play an effective cooling role, and prevent workpiece surface burn.

Driven by the drive system, the screw will transport and compact the materials from the hopper forward. Under the mixed action of the heater outside the barrel, the screw and the barrel, the materials will gradually melt. A certain amount of molten plastic has accumulated at the head of the barrel. Under the pressure of the melt, the screw will slowly retreat. The backward distance depends on the amount required by the metering device for one injection. When the injection amount reaches the predetermined amount, the screw stops rotating and backward.
