xiehe model

No matter what material the prototype is made of, when it exceeds certain usage conditions, the prototype may be deformed or cracked. What should I do when the prototype is deformed or cracked? Is there any way to remedy it? ?The following Shenzhen Xiehe Prototype Processing Factory will tell you about the remedial measures for deformation or cracks in the prototype model. You can read the content to understand.

1. After the prototype is deformed, there is a certain residual stress inside it. The stress should be relieved before the hand plate is processed, and the internal stress can be eliminated by using stress annealing and natural aging.

2. Most of the hot cracks of the prototype are caused by mechanical stress, which are cracks caused by the solidification of the metal. The solution is to improve the prototype structure so that it has fewer surfaces in contact with the metal. Another way is to increase the hot brittleness 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 the deformation of the prototype, which often occurs in the place where the prototype is stretched. Cold cracks are generally small, but such cracks are irreversible defects and can only be redone. Cold cracks often occur when making large and thin prototypes. Similarly, preventive measures are to reduce internal stress and control the phosphorus content of the metal.

It can be seen that once the prototype model is deformed and cracked, the remedial measures are very troublesome, and even some deformation and cracks cannot be remedied. The major defects of the prototype model, so the deformation and cracks are mainly preventive measures, and try to avoid deformation and cracks.

The above is an introduction to the remedial measures for deformation or cracks in the prototype model. If you encounter such a situation, you can use the above three methods. Pay attention to Shenzhen Xiehe Prototype Processing Factory to learn more about the prototype model.
