I want to achieve a uniform appearance when directly applying black chrome to aluminum die casting.

Conditions for current density that result in a matte finish! A successful case of stable blackening of aluminum die-cast materials.

We would like to apply a blackening treatment to aluminum die-cast materials, but with other companies' plating, the black color did not develop well and resulted in a light gray appearance. As a workaround, we have been using oil to eliminate surface irregularities, which has been a concern. Therefore, we proposed to adjust the component ratio of black chrome plating to achieve a matte black appearance while maintaining the plating state. To also address cost reduction, we considered eliminating the nickel plating that was previously applied as a base layer and directly applying black chrome plating to the material, successfully achieving stable blackening of aluminum die-cast materials. 【Issues】 ■ The appearance of current products from other companies is uneven. ■ An additional step of applying oil becomes necessary. ■ Oil is not required for product assembly and becomes a cost-increasing factor. ● For more details, please visit our company website and contact us.
