1. What is Sheet Forming?
Sheet Forming is a manufacturing process that plastically deforms a sheet metal by applying an external force without removing the material, and is widely used in the automotive, aerospace, and consumer electronics fields
Core processes include:
Bending: The Kunshan plant uses AI simulation rebound compensation technology to control the angle error within ±0.1° to achieve complex bending such as V-shaped and U-shaped bending through punch/die combination.Hydraulic Forming: Replacing rigid molds with liquid pressure reduces scratches on the surface of parts and increases the forming limit (e.g., 30% increase in the elongation rate of aluminum alloys).
Deep Drawing: Used for the production of cylindrical and box-shaped parts, the multi-station linkage technology of the Kunshan factory can complete 3-5 processes of the traditional process at one time.
