How can the prototype model not deform

prototypes are involved in many fields, by making the prototype, we can see more intuitively whether the product has fluidity or aesthetics in the design, which is also a direct reason why designers consider making the prototype, make them more smooth in the process of product development. However, after all, the prototype is a prototype, and the quality of the real product is still different. In the process of use, the influence of external force, temperature, environment and other factors will cause the prototype to crack or deform. So, how to ensure that the prototype model is not deformed? The following is introduced by the extension model.

The three major methods for preventing prototype deformation:

I. Prevention of prototype deformation requires uniform thickness and symmetrical shape of the prototype during design. The method of simultaneous solidification is used in the casting process. This method reduces the internal stress of the prototype to prevent deformation. In addition, the prototype model with long shape and its measures to prevent deformation are the measures of anti-deformation method, and its principle is to eliminate the stress of the prototype by pre-deformation with equal deformation but opposite direction in the prototype.

there is a certain residual stress inside the prototype after deformation. Stress should be eliminated before the prototype is processed. Stress annealing and natural aging can be used to make the internal stress disappear.

2. Most of the prototype thermal cracks are caused by mechanical stress and are caused by metal solidification. The solution is to improve the prototype structure so that it has less surface contact with the metal. Another way is to increase the thermal fragility of the metal by controlling the sulfur content of the metal.

3. The cold crack of the prototype is the crack of the product at low temperature. This is caused by prototype deformation, which often occurs where the prototype is stretched. Cold cracks are generally small. Cold cracks often occur when making large and thin prototypes. Similarly, the precautionary approach is also to reduce internal stress and control the content of phosphorus in metals.
