Unscrewing Plastic Injection Mold

This article's cold runner injection mould for Unscrewing Plastic Molding made of TPU material fully considers the importance of material selection during the design and production process. Cold runner plastic molds using 718 mold steel, with reasonable design and production technology, are entirely possible to meet the mold tool requirements of 1 million times.

TPU material is very suitable for making such high-demand injection molds due to its high wear resistance, wide hardness range, high mechanical strength, good processing performance and good recyclability. Specifically, high wear resistance means that the mold can maintain stable performance for a long time and reduce wear during use; a wide hardness range and high mechanical strength ensure the structural stability and durability of the mold; good processing performance makes The mold manufacturing process is more efficient and precise; while good recyclability is beneficial to environmental protection and cost control.

The selection of mold steel is also an aspect that cannot be ignored in mold production. 718 mold steel is widely used in the field of injection mold manufacturing due to its high temperature strength, corrosion resistance, oxidation resistance, good processing performance, high toughness and good dimensional stability. This kind of mold steel can meet the needs of molds working in high-temperature and high-pressure environments, ensuring the life and stability of the mold.

In the design of cold runner injection molds, attention must also be paid to the design of the cold runner pouring system, including the selection and layout of flanges, spouts, runner plates and other accessories to ensure that the molten TPU material can flow smoothly into the mold. cavity and smoothly demolded after cooling.
