Bending machine is an industrial equipment used to bend metal sheets or profiles into a specific shape. It applies pressure to the workpiece through the cooperation of the upper and lower molds to achieve precise bending processing. Bending machines can be divided into mechanical bending machines, hydraulic bending machines, CNC bending machines and pneumatic bending machines according to the driving mode; bending machines are widely used in many industries, including but not limited to: automobile manufacturing, aerospace, construction industry, home appliance manufacturing, machinery manufacturing, used to manufacture various metal structural parts and produce electronic equipment casings; the metal materials processed by bending machines include: stainless steel, carbon steel, aluminum alloy, copper, titanium alloy. Production advantages: high precision, high efficiency, versatility (suitable for a variety of materials and thicknesses, able to handle complex shapes), strong flexibility and high safety.
