Blow molding molds are generally made of engineering plastics or metal materials with high hardness, high wear resistance, high corrosion resistance and high thermal stability. Commonly used engineering plastics include polystyrene (PS), polypropylene (PP), polyvinyl chloride (PVC), polyethylene (PE), polycarbonate (PC), etc.; commonly used metal materials include aluminum alloy, steel, etc. According to the requirements of different blow molding products, it is very important to choose the appropriate mold material. For example, for products that require high gloss, molds are usually made of materials with high surface finish to ensure the surface quality of the finished product; for products that require high strength, it is usually necessary to use materials with high hardness to make molds to ensure the strength of the finished product. Blow molding molds are made of metal materials with excellent wear resistance, high hardness, and high corrosion resistance. There are usually the following options, such as: Steel: ordinary die steel, alloy steel, stainless steel, tool steel, etc. Aluminum alloy: high-strength aluminum alloy, high-hardness aluminum alloy, etc. Copper alloy: such as hard copper, tin copper, etc. Cast iron: gray cast iron, ductile iron, etc. Titanium alloy, molybdenum alloy, etc. Among them, the selection of suitable blow mold materials depends on factors such as the shape, size, quantity, production cycle and service life of plastic products. For example, for high-demand products, stainless steel or titanium alloys are often used to make molds, while for simple low-demand products, ordinary mold steel or cast iron can be used.
