deep drawing is a metal part produced by a deep drawing die, and deep drawing is a kind of stamping process. deep drawing parts are a kind of stamping parts with relatively technical content, and it is also more difficult to produce. Stamping and drawing processing plants need to know how to use lubricants when producing drawing parts. INVITECH Precision has focused on custom processing of precision metal drawing parts for more than 10 years, and has accumulated rich experience in drawing processing. Next, INVITECH Precision will give you an analysis of what to pay attention to when using lubricants during the metal deep drawing process.

Pay attention to the following when using lubricating oil in the processing of drawing parts:

1) There is no need to apply lubricant on the entire surface of the material.

2) Lubricant is only applied to the place where the material is in contact with the mold, and it is applied every few times.

3) It is not allowed to apply lubricant on the surface of the punch and the material in contact with the punch, because this will cause the blank to slide along the surface of the punch, which will cause the stretched part to elongate and thin.

4) When the thin material is stretched for the first time, there is no need to apply lubricant on the material, because the lubricant will reduce the friction between the flange and the mold and cause the formation of wrinkles. However, this way you can apply lubricant to the rounded corners of the cavity of the cavity.

5) During one stretch before the shutdown, you only need to apply lubricant on the outer surface of the stretched part or the cavity of the cavity.

6) Lubricant-coated materials or blanks should be stained or contaminated, otherwise it will damage the drawing parts and drawing molds.
