Who We Are

Industrial power solutions built around the process.

Guangdong Qeehua Industry Equipment Co., Ltd. is a specialized manufacturer of electroplating rectifiers and DC power supplies for surface treatment and wet processing lines.

QEEHUA focuses on the part of manufacturing that matters most: matching equipment to the actual process. From voltage and current requirements to cooling, automation and installation conditions, we work backward from the production goal rather than starting with a generic catalogue model.

Manufacturing Capability

From engineering review to final testing.

A clear production workflow keeps project information visible from the first technical discussion through delivery.

Requirement Review

Confirm application, voltage, current, cooling, communication and installation conditions.

Engineering Design

Match power modules, protection design and cabinet structure to the process.

Assembly Control

Follow component inspection, wiring and cabinet-assembly standards during production.

Final Testing

Check output stability, protection response, heat dissipation and operating performance.

Quality Control

Reliable output starts before final inspection.

For production lines, output stability can influence coating consistency, yield and operating cost. QEEHUA therefore places quality checks throughout production—not only at the end.

Material & Component ChecksIncoming material inspection and component selection based on project requirements.

Wiring & Assembly ControlStructured assembly and wiring inspection during cabinet production.

Full-Load TestingVerification of output behavior, protection functions and operating performance.

Delivery DocumentationClear project information for installation, commissioning and ongoing service.

ISO 9001 CE SGS Full-Load Testing

40+ countries Project communication from inquiry to after-sales support.

Global Service

A technical partner before and after the order.

QEEHUA supports customer projects with technical communication, equipment selection, specification confirmation, production updates and after-sales troubleshooting.

Before OrderReview industry, process, tank conditions, output requirements, cooling method and automation needs.

During ProductionConfirm specification details, cabinet layout, project documentation, packing and delivery requirements.

After DeliveryProvide commissioning guidance, parameter adjustment support, fault analysis and maintenance communication.

Let’s build the right power system for your process.

Share your application, voltage, current, cooling and control requirements. QEEHUA can review the project and recommend a suitable industrial DC power configuration.
