An electroplating rectifier is the “heart” of the plating line. It converts ordinary AC into stable, controllable, high-precision DC, enabling more uniform deposition and making the chain’s plating quality controllable, reproducible, and improvable.
Without a stable rectifier, achieving high-grade coatings is difficult. Common consequences include:
- ✘ Blooming
- ✘ Uneven coatings
- ✘ Burns
- ✘ High defect rates
These issues directly drive order losses and rising production costs.
2. What core industry pain points does it address?
Electroplating and surface-treatment firms routinely face four major challenges:
Pain Point 1: High electricity costs and energy consumption
- Older rectifiers are inefficient, consume more power, and run up long-term electricity costs.
Pain Point 2: Unstable output leading to high rework
- Large ripple and current drift cause coating defects.
Pain Point 3: Poor heat management and short equipment life
- Moist, sour-gas environments corrode internal structures.
Pain Point 4: Lack of smart management
- No remote monitoring, no parameter traceability, no integration with automated lines.
3. How does QEEHUA solve it?
- Energy savings of 20–30% — immediate reduction in electricity costs
