What are the ways to make a prototype model
At present, in our prototype industry, there are three commonly used methods for making prototype models: cnc processing, 3d printing and silicone compound molds. Each processing method has different characteristics, and you should choose which one according to your own product requirements. Method, the following is the production of prototype model manufacturer Tai Tengxin to explain to you:
1. Cnc processing: The prototype model made in this way has high accuracy. If you have high accuracy requirements, it is recommended to choose cnc processing. The main processing materials are: ABS, PC, PMMA, PA, POM, PE, bakelite, aluminum alloy , Stainless steel, brass, etc., PC, PMMA are used for processing transparent parts, PC is semi-transparent, PMMA is fully transparent.
2. Silicone compound mold: Generally, it is made by vacuum silicone compound mold. The production cycle of silicone compound mold is short and the price is cheap. Under normal circumstances, the service life of silicone mold is about 10 times. Under vacuum conditions, the casting material is processed Defoaming, stirring, preheating, injection molding, and secondary curing molding in a thermostat; suitable for small batch production of prototypes, the cost is lower than CNC processing, but the quality is not as good as CNC processing.
3.3D printing: Laser rapid prototyping. The two production methods like SLA/SLS belong to 3D printing. In the current 3D printing technology, metal materials can be made, but the surface effect is relatively rough, which is more suitable for processing those appearances and structures. Complicated prototypes can produce prototypes that cannot be processed by cnc.
To sum up: you need to choose the production method of the prototype according to your own requirements. CNC processing is suitable for high-precision prototypes, and silicone compound molds are suitable for small-batch prototype production with low cost. 3D printing is suitable for processing complex prototypes.
