不管是什么材料制作的手板模型，当它超出了一定的使用条件限制，可能就会出现手板模型变形或是裂纹，那么遇到手板模型产生变形或是裂纹应该怎么做?还有没有方法可以补救?下面济南手板加工厂就来给大家说说手板模型产生变形或是裂纹的补救措施，大家可以看看内容了解一下。

No matter what kind of material is used for the prototype, when it exceeds certain service conditions, the prototype may be deformed or cracked. What should we do if the prototype is deformed or cracked? Is there any way to remedy it? Next, Jinan Handboard Processing Factory will talk about the remedial measures for the deformation or crack of the handboard model. You can have a look at the contents to understand.

1、手板发生变形后，其内部存在一定的残余应力。在对手板加工前应该应力。可以使用应力退火和自然时效来使内部应力消失。

1. After the hand board is deformed, there is a certain residual stress in it. The stress shall be relieved before the fabrication of the handboard. Stress annealing and natural aging can be used to eliminate internal stress.

2、手板热裂纹多数是由于机械应力造成，是在金属凝固所造成的裂纹。解决办法是改良手板结构，使其与金属接触的面更少。另外一种办法是在控制金属的含硫量而增加金属的热脆性。

2. Most of the hot cracks in the hand board are caused by mechanical stress, which is caused by metal solidification. The solution is to improve the structure of the hand board so that it has less contact with the metal. Another method is to increase the thermal brittleness of metals by controlling the sulfur content of metals.

3、手板冷裂纹是在低温下所产品的裂纹。这是由于手板变形引致的，常常出现在手板受拉伸的地方，冷裂纹一般比较细小，但这种裂纹是不可逆的缺陷，只能重做。在制作大型而薄的手板时，常发生冷裂纹。相似，预防办法也是减小内部应力和控制金属中磷的含量。

3. The cold crack of the hand board is the crack of the product at low temperature. This is caused by the deformation of the hand board, which often occurs in the place where the hand board is stretched. The cold crack is generally small, but this crack is irreversible and can only be redone. Cold cracks often occur when making large and thin hand boards. Similarly, the preventive measures are to reduce the internal stress and control the phosphorus content in the metal.

可以看出一旦手板模型发生变形和裂纹，补救措施非常麻烦，甚有些变形和裂纹是无法补救的，是手板模型的重大缺陷，所以变形和裂纹是以预防措施为主，尽量避免出现变形和裂纹。更多相关内容就来我们网站http://m.metferro.com咨询了解吧！

It can be seen that once the hand model is deformed and cracked, the remedial measures are very troublesome, and even some of the deformations and cracks can not be remedied, which are major defects of the hand model. Therefore, the deformation and cracks are mainly preventive measures to avoid deformation and cracks as much as possible.
