How to reserve the deformation allowance of die heat treatment? Kunshan Aoma Xiaobian tells you that our industry regulations are based on the normal theoretical allowance method (for the thickness direction) for the template allowance: 3 ‰ of the length direction, but considering the actual situation of the customer, it is adjusted as follows:

一、厚度为正常厚度（不是太薄也不是很厚），长宽比（长度除以宽度）也为正常数值情况下：根据长度方向的千分之二来放（0.5mm为下限）

1、 When the thickness is normal (not too thin or too thick), and the length width ratio (length divided by width) is also normal, it is placed according to two thousandths of the length direction (0.5mm is the lower limit)

比如：a、一块净尺寸为20x200x300的SKD11模板，厚度就可以按300乘以千分之二（0.6mm来放）

For example: A. for a SKD11 template with a net size of 20x200x300, the thickness can be 300 times two thousandths (0.6mm)

b、一块净尺寸为10x100x150的SKD11模板，厚度就按0.5mm的下限来放，因为如按千分之二来放相当于只有0.3mm那肯定不够

b. For a piece of SKD11 formwork with a net size of 10x100x150, the thickness shall be placed according to the lower limit of 0.5mm, because if it is placed according to two thousandths, it will be only 0.3mm, which is certainly not enough

模具热处理变形余量怎么留？

二、如果厚度特别薄或者长宽比太大，模板的热处理余量就要另放余量了：

2、 If the thickness is extremely thin or the length width ratio is too large, the heat treatment allowance of the formwork shall be added:

比如：a、一块净尺寸为8x300x300的薄板如按理论值应该是放0.6mm，但由于模板太薄很容易变形可以适当再加个0.2mm以确保后续做的出来

For example: a. a thin plate with a net size of 8x300x300 should be placed 0.6mm according to the theoretical value, but because the template is too thin, it is easy to deform, so it can be added 0.2mm to ensure the follow-up

b、一块净尺寸为15x30x800的细长板如按理论值应该放1.6mm，但由于长宽比太大也容易变形也要适当再加些余量以确保后续做的出来

b. A slender plate with a net size of 15x30x800 should be placed 1.6mm according to the theoretical value. However, it is easy to deform due to the large length width ratio. It is also necessary to add some allowance to ensure that it can be made later

c、一块净尺寸为6x30x800的细薄长板，由于板又薄、长宽比又太大那更容易变形（这个在原材料铣磨加工时就会产生变形，再加上热处理应力的释放那就更多的变形了）

c. A thin and long plate with a net size of 6x30x800 is easy to deform because the plate is thin and the length width ratio is too large (it will deform when milling raw materials, and it will deform more when heat treatment stress is released)
