Selection Guide

How to Select the Right Chemical Surface Treatment Line?

Four design factors that determine coating quality, throughput, and operating cost.

01
Tank Materials

Tank Material & Chemical Compatibility

Match each tank to its chemistry and temperature: PP, PVDF, PFA, titanium, or stainless steel. Avoid titanium in fluoride baths.

02
Takt Time

Hoist Automation & Throughput

Capacity is set by the longest process step and hoist transfer time. Simulate scheduling before fixing the layout.

03
Bath Control

Temperature, Agitation & Dosing

Automated dosing and continuous filtration keep every bath within its operating window.

04
Ripple < 1%

Rectifiers & Current Density

Hard anodizing and precision plating need low-ripple rectifiers with controlled current density.
