Die casting mold seat is a device used to fix die casting molds, usually made of high-strength materials, with the ability to withstand high pressure and high temperature. Its design and manufacturing require precision tolerance assurance to ensure accurate positioning and stability of the mold. Firstly, the external dimensions of the die-casting mold base need to be customized according to customer needs. This includes the size, aperture, and spacing of the base. Each mold base needs to accurately meet the dimensional requirements of the mold to ensure that the mold can be accurately installed on the base and remains stable during use. Secondly, the aperture tolerance of the die-casting mold seat also needs to be strictly controlled. The aperture on the mold base must match the positioning pin or hole on the mold to ensure that the mold can be accurately positioned on the mold base. This requires strict control of aperture tolerance during the manufacturing process to ensure the accuracy of the fit with the mold.
