与我们的生活的生活息息相关，几乎所有的制造业都离不开，总体来说，行业在近年来得到迅猛发展，主要原因有以下几方面。&苍产蝉辫;
1、钣金加工生产能力需求提高。中国越来越成为国际加工制造中心，加上国外投资的不断增加，金属精加工的能力需求不断加大，而金属加工行业中的电器控制箱、机器外壳等一般来说都是钣金件，所以钣金加工能力需求也不断提高。&苍产蝉辫;
2、钣金加工利润高。如冲压一般可以达到30%左右，而则可以达到50%甚至更多。&苍产蝉辫;
3、钣金加工加工精度要求低，上手容易。就钣金加工而言，精度在几丝是很司空见惯的事，而工艺的复杂性也比较高，甚至有些零件工序达到几十道之多。所以金加工公司通常需要各种各样的机械设备以满足不同工艺要求。而钣金冲孔精度一般在±0.1尘尘左右，折弯精度一般可以达到±0.5尘尘,因此相对于金加工来说，精度低得多。
Sheet metal processing is closely related to the life of our life, almost all of the manufacturing industry can not be separated from sheet metal processing. In general, the sheet metal processing industry has developed rapidly in recent years. The main reasons are the following aspects.
1, the production capacity demand of sheet metal processing is improved. China has become more and more international manufacturing center. With the increase of foreign investment, the demand for metal finishing is increasing, and the electrical control box and machine shell in the metal processing industry are generally sheet metal parts, so the demand for the processing capacity of metal sheet metal is not broken.
2, sheet metal processing profit is high. For example, stamping can reach about 30%, and laser cutting can achieve 50% or more.
3, sheet metal processing accuracy is low, easy to get started. As far as sheet metal processing is concerned, accuracy is very common in several threads, and the complexity of the process is relatively high. Even some parts work in dozens of ways. Therefore, gold processing enterprises usually need a variety of mechanical equipment to meet different technological requirements. The punching accuracy of sheet metal is usually about 0.1mm, and the bending accuracy can reach 0.5mm. Therefore, the accuracy is much lower than that of gold processing.
