How steel mold work? Steel molds are mainly used in high-volume injection molding manufacturing. It mainly uses different processes. First, the steel is drilled, milled, ground and so on.And then the molten plastic is injected into the mold cavity through a high-pressure injection molding machine which will cooled and solidified it under high pressure. Advantages: Compared with aluminum molds, steel molds have the advantages of extremely long service life, strong durability, high manufacturing precision, and the ability to withstand high pressure. Steel molds are not easily deformed and worn, and can withstand high-frequency use. Disadvantages: The manufacturing cycle of steel molds is long and requires relatively high manufacturing costs. It is not suitable for scenarios such as small batches or initial trial production. Steel molds are suitable for high-volume injection molding manufacturing. It can be used to produce high-strength, high-precision, and high-quality injection molded products, such as automotive parts, TV casings, and other products that are in high demand.
