The main methods of hand model production include CNC machining, 3D printing and silicone replica. ‌ These methods have their own characteristics and are suitable for different needs and scenarios.

First of all, ‌CNC machining ‌ is one of the main processing methods in the current hand plate industry. CNC machining accuracy is very high, can reach 0.01mm processing accuracy, suitable for a variety of materials, including metal and plastic. The hand plate machined by CNC has high strength and is suitable for products with very high precision requirements. Common processing materials include ABS, PC, PMMA, PA, POM, PE, bake lite, aluminum alloy, stainless steel, brass, etc .

Secondly, ‌3D printing ‌ is a kind of rapid prototyping technology by laser. 3D printing has a short production cycle, which is suitable for machining complex structures and appearances, especially those parts that CNC machining cannot handle. 3D printing can use metal materials, but the surface effect is rough, suitable for small batch production and complex structure of the hand plate production .

Finally, ‌ silicone duplicate ‌ is a method of copying by silicone mold. This method has short production cycle, low cost and is suitable for small batch production. The advantage of silicone mold is that a prototype can be made quickly, but the service life of the mold is limited, usually about 10 times. Suitable for hard adhesive, soft adhesive, metal powder mixture ‌.
