How does the 718H mold core material of the Auto Filter Element affect the surface finish and durability of the final product?

718H mold steel is known for its high purity and uniform organizational structure, which enables it to show excellent performance during the polishing process. The uniformity of its internal material reduces the defects and unevenness that may occur during polishing, making it easy to obtain a highly smooth mold surface. This excellent polishing performance is directly reflected in the final product, which significantly improves the surface finish of products such as Auto Filter Element housings. The smooth surface not only improves the aesthetics of the product, but also helps to reduce the adhesion of dirt and impurities, thereby extending the service life of the product.
The polishing performance of 718H mold steel makes it particularly suitable for manufacturing transparent plastic product molds, such as Auto Filter Element housings. During the injection molding process of transparent products, any minor defects on the mold surface may be magnified and affect the transparency of the product. Using 718H mold steel can ensure that the mold surface achieves an extremely high finish, thereby producing filter element housings with high transparency and consistent appearance quality. This is of great significance to improving the overall quality and market competitiveness of the product.
718H mold steel has been pre-hardened before leaving the factory, and its hardness reaches HRC36~40°, which enables the mold to withstand greater pressure and wear during the injection molding process. High hardness and strength not only extend the service life of the mold, but also reduce the product size deviation and surface quality degradation caused by mold wear. This is essential to ensure the quality and consistency of products such as Auto Filter Elements.
718H mold steel has excellent wear resistance and can resist the wear of the plastic melt on the mold surface during the injection molding process. During long-term injection molding production, the mold surface may be worn and scratched due to the scouring and friction of the plastic melt. Using 718H mold steel can effectively reduce this wear and maintain the finish and precision of the mold surface. This helps to ensure that the products such as Auto Filter Element housings produced always meet the quality requirements and reduce the scrap rate caused by mold wear.
718H mold steel also has good corrosion resistance and can resist the erosion of chemicals. During the use of products such as Auto Filter Elements, they may come into contact with chemicals such as oil and coolant. If the mold material is not corrosion-resistant, these chemicals may penetrate into the mold and corrode the mold surface, thus affecting the quality and life of the product. Using 718H mold steel can effectively avoid this problem and ensure the long-term stability of the mold and product.
718H mold steel can maintain stable mechanical properties under high-temperature injection molding environment, and its thermal fatigue resistance can prevent the mold from cracking due to repeated heating and cooling. This feature is very important for the continuous production of Auto Filter Elements, which can reduce the frequency of mold maintenance and ensure production efficiency and product consistency.
