xiehe model

As the name suggests, plastic prototypes are prototypes made of plastic materials. What are the methods of making plastic prototypes? What is the product model plastic prototype usually used for proofing? Next, the Xiehe prototype manufacturer will give you a brief introduction.

The first step of plastic prototype proofing is to verify the appearance. The main purpose of the product is to check whether the appearance is good or not, and to verify whether the appearance of the design is perfect.

The second is the verification function, which realizes the same functions as the real machine and the rationality of operation.

The third is to participate in the exhibition. When the product is not on the market, use this prototype to obtain orders.

The fourth is direct sales. For example, some prototypes of medical equipment are made the same as those produced by molds, and can be directly sold as products in the market.

According to the production method, it can be divided into silicone composite prototype, low-pressure perfusion prototype, CNC prototype and 3D printing prototype.

1. Silicone composite mold prototype

What is silicone lamination? Silicone lamination can be made of many kinds of materials, such as PC and ABS, soft glue. Silicone laminating is also called vacuum complexing. First, a model needs to be printed or CNC processed, and then the original version is used to make a silicone mold, and then the liquid material is poured into the silicone mold. After the liquid material solidifies, a hand model is formed.

2. Low-pressure perfusion prototype

What is low-pressure perfusion? Low-pressure infusion, also known as low-pressure reaction injection molding, is to mix two-component polyurethane materials and inject them into rapid molds at room temperature and low pressure, and form products through chemical and physical processes such as polymerization, crosslinking, and curing of materials. It has the advantages of high efficiency, short production cycle, simple process and low cost. It is mainly used for small-batch trial production in the product development stage, as well as small-batch production of products such as covering parts, unevenness and wall thickness, and has been widely used in industries such as medical technology and automobiles.

3. CNC prototype: It is a way to produce prototypes through CNC lathe or milling machine engraving, which is the mainstream technology of prototype processing.

4. 3D printing prototype: SLA technology is mostly used at present. Using 3D printers is convenient, fast and cheap. Complicated prototype models can be produced quickly. It is that the strength and temperature resistance are poor, and it will change color after a long time.

The above content is the production method of plastic prototype proofing, I hope it can be helpful to everyone. If you want to know more about the prototype, please call the Xiehe prototype manufacturer for consultation.
