Why do the prices of prototype parts vary greatly?

The prototype model is a precision product, mainly used to verify whether the product can be applied. When customizing prototypes, different customers have different requirements. Some customers who have high quality requirements will even develop special materials or processing techniques to meet quality and cost control requirements. The manufacturing cost of the prototype is determined by the material, product quality and production process, so there will be some differences in the quotation of each part.

1. Material processing costs

In the manufacturing process of prototype models, different prototypes require different materials. Some plastic materials are more common, such as ABS, which are relatively cheap, while some materials are more troublesome, such as PPS materials, which are relatively expensive. In addition, in addition to the material, the size of the prototype will also affect the price of the material. The larger the size, the more raw materials are needed to make the prototype, so the higher the price. This is related to the size and structure of the parts. The simple structure means the processing cost is low. The complex structure means the processing is difficult and the processing time is long, so the cost is high. 
2. Material processing methods

In the prototype processing process, different production processes will lead to different costs. For example, CNC machining, 3D printing and vacuum composite models will have different price differences. For example, metal prototypes are more difficult to process than plastic prototypes, which will lead to price diversity.

3. Prototype post-processing process

Prototype post-processing processes include grinding, polishing, sandblasting, oil spraying, oxidation, powder spraying, painting, electroplating, passivation, screen printing, etc. Different post-processing processes have different prices, which will increase the price of a process accordingly. Customers can choose the corresponding post-processing process according to product requirements.
