Hard Chrome Plating Line

Our Hard Chrome Plating Line is engineered for applications requiring extreme wear resistance, hardness (800-1000 HV), and low friction coefficient. This equipment is widely used for hydraulic piston rods, industrial rolls, printing cylinders, molds, dies, and heavy machinery components.

The hard chrome plating system features a gantry-type structure with PLC automatic control, precise current regulation, and bath temperature control. Our advanced design incorporates lead-free platinized anodes, eliminating lead contamination and reducing environmental impact.

Common Challenges in Hard Chrome Plating Production

Manufacturers often face several challenges when operating conventional hard chrome plating processes:

● Uneven coating thickness affecting product quality

● Excessive labor costs caused by manual operation

● Poor current distribution leading to inconsistent hardness

● Environmental concerns related to chrome mist emissions

● Difficult process control for large workpieces

● High maintenance and operating costs

JUNDA Hard Chrome Plating Line is designed to solve these challenges through intelligent automation, precise process control, and integrated environmental protection systems.
