The metal stamping factory solves the problem of stretching and wrinkling, and customers fall in love with you more [Hardware]

Many of the stamping parts produced by the metal stamping factory require a drawing process, and drawing is a problem with a relatively large coefficient of difficulty in mold manufacturing and production. Therefore, in many metal stamping factories, the stretched products may wrinkle. What is the original cause? How should we deal with it? Reason: The blank holder force at the flange is too small to resist excessive tangential compressive stress; it causes tangential deformation, which causes wrinkles after losing stability. Thinner materials are easier to form wrinkles. Countermeasures: 1. Increase the blank holder force of the blank holder and appropriately increase the thickness of the material. 2. Add stretching oil. 3. Adjust the pressing precision of the concave and convex molds, so that the mold can make the raw materials evenly stressed during the stretching work. Hardware, 15 years of ingenuity focused on hardware stamping factory, 20000+ sets of mold making and production experience, 3 million production capacity per day, 16 quality inspections are strictly for quality control. It can quickly solve the problem of your precision requirements, your urgent problems of time, and your quality requirements.
