How much do you know about the alloy screw of precision injection molding machine?

The alloy screw of the precision injection molding machine adopts imported high alloy steel fully hardened, which can effectively withstand high torque and high pressure impact, wear resistance, surface plating, corrosion resistance, smooth and non-porous, reduce surface adhesion and degradation, and meticulous structural treatment.

How does the alloy screw prevent it from slipping?

When the alloy screw is difficult to compact the material at the feed inlet, or when there is not enough adhesion to convey the material along the length of the barrel, the alloy screw will slip. In the pre-forming stage of the alloy screw, when the alloy screw rotates in the barrel to convey the material in the direction of the screw and retreat to accumulate the material for the next injection, the screw will also slip. If the screw starts to slide during the pre-forming stage, the axial movement of the alloy screw will stop as the alloy screw continues to rotate. Usually, the screw slip will lead to the degradation of the material before injection molding, and there will also be product quality problems such as short injection and prolonged processing cycle.

What are the reasons for the easy damage of the flat double barrel

Since the resistance of the cylinder head and the splitter plate in front of the cylinder remains unchanged, the leakage flow rate when the extruded material advances, that is, the flow amount from the diameter gap to the material supply direction increases. As a result, the extruder output decreases. As a result, the residence time of the material in the cylinder increases and the material is decomposed. When the material is polyethylene, the gas produced by decomposition strengthens the corrosion of the screw and the cylinder, forming a vicious circle. Then, let's understand the reasons why the lower flat double barrel is easily damaged!
