| 1 | Vacuum mold | There are limited materials to choose from. If there are requirements for high temperature resistance and chemical corrosion resistance, it is difficult to find suitable materials. | The surface color can be changed by spray painting, polishing, electroplating, etc. | |
| 2 | Injection molding | The material selection is very wide, and you can find materials suitable for almost every scene. | If it is a conventional glossy or matte surface, it can be polished on the mold or directly copied on the product after texturing. It can also be spray-painted to change the surface color, or it can be polished, electroplated, etc. | |
| 3 | CNC machining | There are certain restrictions on material selection, but most common plastics are available, such as PC, ABS, PA6, POM, PPS, PMMA. | The surface color can be changed by spray painting, polishing, electroplating, etc. | |
| 4 | 3D printing | The main material is resin, not real plastic. It just feels similar to plastic. If there are special requirements, such as high temperature resistance and chemical corrosion resistance, it cannot replace plastic. | Can be spray painted to change surface color | |
