选择好的锻件产品跟锻造工艺或者锻造厂家肯定是有关系的，现在有越来越多的锻件厂走向市场，对此，用户挑选锻件产品的难度就增加了。如果对锻件缺乏***的认识，那么，在选择的时候就会多很多顾忌。
The selection of good forging products is closely related to forging process or forging factories. Now more and more forgings factories are going to the market. Therefore, users" difficulty in selecting forgings is increasing. If the forgings are lack of professional knowledge, there will be a lot of scruples when choosing.
锻造是指把加热后的金属材料锻制成各种形状的工具、机械零件或毛坯。锻造过程中要对这些滚烫的金属坯料进行各种加工，因此加工过程中高温、***、振动和噪声是避免不了的。所以锻造过程安全防护很重要。
Forging is a tool, mechanical part, or blank that is forged from a heated metal material to a variety of shapes. In the process of forging, these hot metal billets should be processed, so high temperature, dust, vibration and noise can not be ***oided during the process. Therefore, the safety protection of the forging process is very important.
