Black Electrophoretic Surface Stamping Parts

Dazhe’s China Black Electrophoretic Surface Stamping Parts is a surface treatment process that deposits metal ions onto the material surface via electrochemical reaction. Its working principle is as follows: the material is immersed in an electrophoresis tank, and under the action of electrodes, a smooth and dense electrophoretic film is formed on the material surface. By adjusting parameters such as current density and temperature, the thickness of the electrophoretic film can meet the required specifications, and a uniform black oxide layer is formed on the surface of the film.

Our Black Electrophoretic Surface Stamping Parts Process Chain:

Blanking → Punching → Bending → Drawing → Flanging → Shaping. Multi-station high-speed presses (25–600 tons) enable automated mass production, with a cycle rate of up to 18 strokes per minute and a defect rate reduced to below 0.3%.

Black Electrophoretic Surface Stamping Parts Core Advantages:

1.High Efficiency: Suitable for large-scale automotive mass production. The daily output per mold exceeds 2,000 units, with a material utilization rate of 60%–75%.

2.Lightweight Design: The proportion of aluminum alloy stamped parts has increased from 12% in traditional fuel vehicles to 28% in new energy vehicles, achieving a weight reduction of 20%–30%.

3.Superior Strength: Stamped parts made of hot-formed steel and high-strength steel significantly improve vehicle body crash energy absorption (+40%) and structural rigidity.

4.Complex Forming Capability: Deep curved surfaces, multi-edge lines and reinforcing ribs can be formed in one single operation, meeting the requirements of vehicle body design and aerodynamics.
