Driven by the drive system, the screw conveys and compacts the material from the hopper. Under the combined action of the heater, screw and barrel outside the barrel, the material is gradually melted, and the material is gradually melted at the head of the barrel. A certain amount of molten plastic has accumulated in the part. Under the pressure of the melt, the screw slowly retreats. The retreat distance depends on the amount required for one injection of the metering device. When the predetermined injection volume is reached, the screw stops rotating and retreats
The shrinkage coefficient of each material is different, and the plastic mold must have a reasonable shrinkage rate.
The plastic mold must have sufficient rigidity, otherwise it will deform during clamping and holding pressure, causing "flash".
If the product is ejected while opening the mold, the ejector page of the injection molding machine can be set (but some injection molding machines do not have this function).
