Backup for die-cast mold delays: [gypsum casting]

Gypsum casting is ideal for backup in case of mold delays due to its short lead time and precision comparable to die casting.

Gypsum casting is a casting method using gypsum molds. It is capable of achieving a beautiful surface finish and dimensional accuracy comparable to die-cast products. It has good transferability and can reproduce embossed characters (such as part numbers and company logos) with a φ0.3 tool. It is ideal for producing prototypes, single items, and small lots, as well as for low-volume, high-variety production. Since no molds are required, it can be provided with short lead times and low costs. It is particularly suitable for complex shapes, thin-walled, and hollow shapes that are difficult to manufacture through machining. The finished cast products are dimensionally measured using a three-dimensional measuring machine to ensure quality assurance. Zero draft angles and undercuts can also be accommodated, which are characteristics of gypsum casting.
