Gypsum casting is suitable for small batch production. It produces castings with a casting tolerance grade of CT4 to CT5 without the need for molds.
Gypsum casting is a casting method using gypsum molds. It allows for a beautiful surface finish and dimensional accuracy comparable to die-cast products. It has good transferability and can reproduce raised and recessed characters (such as part numbers and company logos) with a φ0.3 tool. It is suitable for the production of prototypes, single items, and small lots, as well as for low-volume, high-variety manufacturing. Since no molds are required, it can be provided with short lead times and at low costs. It is ideal for complex shapes, thin-walled, and hollow shapes that are difficult to manufacture with 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.
