7075 aluminum plate can be used for automobile stamping parts. When in use, there may be mucous membrane problem, mainly in the pull delay. The mucous membrane will cause traces of strain on the surface of 7075 aluminum plate workpiece.Next 7075 aluminum plate manufacturers to give you advice.

1. When the sticky mold problem occurs, the surface texture of 7075 aluminum plate can be processed to improve the surface morphology and achieve the purpose of hiding oil on the surface of 7075 aluminum plate.For example, shot peening, electric sparks, lasers, and other methods are used to roughen the surface of a finishing roll.7075 aluminum plate before entering the different coiler, the surface is like a fingerprint technology, leaving us countless micro pits.For the stamping process, these pits are numerous storage tanks.When the surface is slightly pitting, more lubricating oil system can slip into a deformation zone;The greater the contact social pressure in the deformation zone, the more lubricating oil is extruded from the micro-storage tank.After long-term use, if the surface of the fine roll is not rough or the surface of the rough roll is worn, the oil carrying capacity is reduced, and after entering the deformation zone, there is no oil available when the lubricating oil is needed to reduce friction, and the problem of sticking mold may occur.

2, another way to hide oil on the surface is phosphating.Galvanized sheet surface by phosphating treatment can be attached to lubricating oil, when the need for lubricating oil, can be extruded through the high contact pressure in the deformation zone.

3, again in 7075 aluminum plate surface coated with dry lubricant, is also a good way.Dry lubricant can effectively isolate the contact between 7075 aluminum plate and the surface of the mold, greatly reducing friction. It should be noted that dry lubricant has poor fluidity and is not easy to run on the side of the mold. There is no oil film protection on the side of the mold, and shear debris is easy to accumulate on it, causing the problem of side hair-raising.
