During the metal molding process, the lubricating fluid is a good thing. When the metal is molded, the workpiece and the mold are inevitable to occur serious impact, squeeze and scraping. The instantaneous temperature and pressure of certain parts of the mold may be large enough to cause the workpiece-mold contact zone to indicate softening and large elastic deformation, after multiple repeating extrusion, resulting in a permanent partial collapse of the mold. There is no isolation of the lubricating fluid, and the workpiece metal can even be coldly welded to the mold metal to form galling.
In the process of punching the sheet, the good lubricating fluid can make the plate metal more easily slid on the surface of the mold, more uniform, which makes the heat generated by the friction be taken away.
But now many of the Western host plants have many non-technical factors Metal Stamping for the use of lubricants. For example, a very popular statement in Europe has been used in the use of no lubrication of the stamping process. It is said that this is correct and friendly environment. Some people publish some articles to advocate these views. In the United States, the situation is similar, in our company, if you want to introduce any new lubricant, its review approval process is very harsh. In fact, in 10 years we don’t have any new lubricating fluid through the review approved. There is also a trend is that the stamping manufacturer is convenient for management, and tends to minimize the type of lubricating liquid, hate can not use only one lubricant, whether it is Blank Washing (Plate cleaning) or Re- LUBE (lubricated), only one lubricating fluid. Workers on our stamping lines don’t like to use lubricants. Too many lubricants dripped, making it greasy. The welding, rubber and painting processes behind stamping also do not like lubrication. At the main plant, cleaning is almost impossible after stamping.
Other host plants in the United States, making any new lubricating fluid through review and approval, it is also very difficult. GM even passes a joke, saying if you want to introduce a new lubricant, only in the spot, prove that it is mighty, and it is possible to obtain approval.
In summary, the current environmentally friendly and political correct atmosphere makes the technical bureaucratic system of the US Main Factory, almost unable to accept any new lubrication. There is no way, you can only let suppliers in their own plants, use new high-efficiency lubricants to produce those difficult parts, then wash the product, and send them to work.
