Our chemical plating tanks are the largest in the city. We offer zinc and manganese phosphate coatings. We use an immersion process in which the solution reacts chemically with the surface of the part being coated to form extremely thin layers of crystalline phosphates. Thickness for both coatings is 0.0002″–0.0006″.
Both zinc and manganese phosphate are used to prevent corrosion. They also help to avoid galling or scoring of threads.
Our systems are fully vented to allow for clean, safe working environments.
