Leading Electroplating Equipment Supplier
A premier manufacturer of acid-resistant wet process systems and automated plating lines.
The Challenge
Conventional PVC and PP sheets suffered from degradation and weld leakage in high-concentration sulfuric and chromic acid environments above 60°C. Frequent maintenance, downtime, and chemical contamination reduced plating efficiency.
Frequent Downtime & Chemical Cross-Contamination
The Qeehua Solution
QEEHUA upgraded the system with industrial-grade beige PP sheets, PPH piping, reinforced U-slot structures, and void-free PP welding technology. The solution delivers reliable operation from 0°C to 80°C with durable, leak-resistant performance.
