Say plastic hand plate processing mode and processing characteristics

Plastic handboard model is made of plastic material through cnc processing, 3D printing and complex mode to produce, plastic handboard processing technology: CNC handboard processing, silicone mold complex mold hand board, 3D printing hand board, RIM low pressure perfusion, CNC processing manufacturers say plastic handboard processing methods and processing characteristics.

First, CNC hand plate

Machining accuracy can reach 0.05mm. The main materials of CNC processing are: ABS, PC, PMMA, PA, POM, PA+ glass fiber, bakelite. ABS is a common and commonly used plastic material. PC and PMMA are used for adding transparent parts. PC is translucent and PMMA is fully transparent, such as lenses and glasses of mobile phones. The ABS raw material density of plastic hand plate is lower than that of injection product ABS. After processing, the internal molecular chain is cut and broken.

Two, compound mold hand plate

The machining accuracy is +0.15mm/100mm. Its material is liquid PU, performance has ABS, PC and so on. For small batch of 10~100 sets of plastic products, this processing technology is suitable, the price cycle has an advantage, is a good method of short-term small batch products.

Three, 3D printing hand board

The processing accuracy is 0.1mm. For some complex shape surface fine parts is more suitable, such as toys, crafts and so on. But because its processing accuracy is lower than CNC hand board, the material is brittle, the plastic hand board produced is not conducive to structural certification, so we think that the use value of SLA laser rapid prototyping is that he can form a good complementary role with CNC processing, it can complete the details of CNC processing.

Four, RIM hand board

Machining accuracy is +0.2mm/ 100mm. At present, ABS mold and aluminum alloy mold are used in this process. ABS mold life (about 300 pieces), aluminum alloy mold life (about 1000 pieces). The material is liquid PU, and the finished product copied out is also plastic products. It is mainly suitable for large plastic hand plate models with simple structure, such as car bumpers, medical panels and so on.
