The quality of the prototype will directly affect the product quality, yield, cost, production of the new products, the cycle of the product updating, the adjustment of the product structure and market competition, therefore, the economic situation put forward higher requirements on the quality of the prototype.
How to improve the quality of the prototype reasonably, which is the key to realize a leap in the manufacturing. How to make qualified prototypes efficiently under the condition of high accuracy and low cost, which has gained much attention increasingly.
The quality of the prototype includes the following four aspects:

1. The quality of the products: the stability of the product size, compliance, the smoothness of the product surface, and the utilization of the product material, etc.
2. The use of the life: in the premise of ensuring the product quality, the times of the cycle finished by the prototypes or the units of making products.
3. The maintenance of the prototype: whether it belongs to the most convenient to use, demoulding easily, the time of the auxiliary production as short as possible.
4. The cost of the repair, and the cycle of the repair, etc.

The basic way to improve the quality of the prototypes:

1. The design of the parts should be reasonable, choosing the structure scheme as best as possible, the designer must take the technical requirements and structure into consideration, which must meet the process and feasibility of the prototype.
2. The design of the prototype is one of the most important step to improve the quality of the prototype, which need to take many factors into consideration, including the selection of the prototype material, the available of the prototype structure and safety, the process of the parts and the convenience of the repair, which should consider thoughtfully before the beginning of the design.

The selection of the prototype material should not only meet the customers’ requirements on products equality, but also need to consider the costs of the material and the strength of the set period, of course, we should according to the types of the prototype , working mode, processing speed and the main failure forms ,etc. to choose the material. For example, the main failure form of the blanking die is the blade wear, so we should choose the material with high hardness on surface and good abrasion resistance. While the stamping die mainly subjected to the cyclic loading, easy to cause the fatigue crack on the surface, leading to the surface spalling, so we should choose the material with good tenacity. In addition, the drawing die should choose the material with low coefficient.
