- Hardware automatic welding supporting production line


Core Advantages
Uniform Pneumatic Key Clamping, No Thin Plate Deformation
Multiple independent cylinders press synchronously with even clamping force. 0.3-5mm thin stainless steel won't wrinkle during welding; weld flatness improves by 60% compared with single-point clamping.
