CNC processing of plastic hand model is a commonly used method of making hand model with the characteristics of fast forming. The manufacturing process of plastic hand model is CNC numerical control processing and silicone mold. There is also a kind called laser rapid prototyping, which has a fast production speed. However, it is not recommended because of poor precision of finished products and poor surface quality. So do you know how to deal with the flaws of the plastic hand model? Next, the Xiehe prototype processing factory will give you a brief introduction.

There are four kinds of materials for making plastic prototypes: ABS, PC, PMMA, and PU. ABS is the most commonly used material for making prototypes; PC and PMMA are used for making transparent parts; PU is the material for making small batches of silicone molds. ABS is machine-made into blocks, and its density is lower than that of injection-molded ABS. After it is processed, the internal molecular chains are cut and broken. Therefore, the prototype made of ABS has low strength and is easy to break. It cannot be used as a product for sale. Usually, CNC processing of plastic hand model mainly includes the following three designs.

1. For product copy design, experienced engineers use a precision laser three-dimensional measuring instrument to capture product data with high precision and complete product design. Also known as reverse engineering.

2. Appearance design, through market research and analysis, continuous communication with customers, screening, and improvement, until the concept of appearance is accurately positioned to adapt to the market and consumers.

3. For product structure design, on the basis of fully understanding its functional principles, follow the appearance and shape, and refer to various original devices to determine the most reasonable structural design in all aspects of the product.

The defects left by CNC processing of plastic prototype models need to be manually removed. The specific method is: it can be polished with sandpaper or polished with polishing paste. During this period, some ash spraying treatments can also be used to detect the effect and quality of artificial polishing. Hand grinding is basically a necessary process for hand products. After a part is processed by CNC machine tools, there will be many burrs and knife marks on the surface. These machines are unavoidable. The production of cnc prototype model cannot guarantee the perfect appearance of the product, so it needs to be processed by manpower.

The above content is the method to deal with the defects of the plastic prototype model, and I hope it can be helpful to everyone. If you want to customize the prototype, please call the Xiehe prototype processing factory, we will serve you wholeheartedly.
