As a key component of plastic bottle forming, blow molding molds have always occupied a very important position in the packaging market.In order to develop a beautiful new bottle-shaped blow mold, it usually requires a high cost.Choosing a high-quality mold manufacturer to produce high-quality molds will save you a lot of money.In particular, the longer the service life of the blow molding mold, the higher its cost performance.The most important factor that determines the service life of the mold is often the wear resistance of the mold material.The mold must withstand considerable compressive stress and friction during work, which requires the mold to maintain dimensional accuracy even under strong friction.There are three main types of mold wear: mechanical wear, oxidative wear and melt wear.In order to improve the wear resistance of the die steel, it is necessary not only to maintain the high hardness of the die steel, but also to ensure that the composition, shape and distribution of carbides or other hardened phases in the steel are reasonable.For molds that are in service under heavy-duty and high-speed wear conditions, it is required that a thin and dense oxide film with good adhesion be formed on the surface of the mold steel to maintain lubrication and reduce melt wear such as adhesion and welding between the mold and the workpiece, and at the same time reduce oxidative wear caused by oxidation on the surface of the mold.Therefore, the working conditions of the mold have a greater impact on the wear of steel.
