Rapid prototyping: Rapid prototyping is a manufacturing technique based on three-dimensional models. By converting the three-dimensional model into a physical model, a part of the sample or mold can be quickly manufactured, shortening the manufacturing cycle. At the same time, rapid prototyping can also be used for complex structures, hard-to-process materials or customized mold manufacturing.
3D printing: 3D printing is a technology that uses materials to build three-dimensional entities layer by layer. By converting three-dimensional models into two-dimensional slices, and then stacking the material layer by layer to form the entity, the manufacture of complex structures can be achieved. 3D printing is suitable for small-batch, customized mold manufacturing, which can improve production efficiency and reduce costs.
Precision casting: Precision casting is a technology that uses a precision casting process for mold manufacturing. By controlling parameters such as the composition of the investment mold material, pouring temperature and cooling speed, high quality and high precision castings can be produced. Precision casting is suitable for high-volume, high-demand mold manufacturing, which can improve production efficiency and reduce costs.
