Manufacturing Process & Production Facilities

Direct Industrial Factory

Integrated Manufacturing Engineered for Zero-Defect Power Conversion

At Guangdong Fenvix Technology Co., Ltd., we maintain full proprietary control over every phase of production. Unlike trading intermediaries that outsource cabinet design or rely on third-party sub-assemblies, our 3,000 m² Guangdong facility integrates precision mechanical sheet metal processing, copper busbar milling, electrical harness manufacturing, and specialized power electronics testing under one roof.

From 15,000A high-frequency electroplating rectifiers and high-voltage DC sources to solid-state 400Hz static frequency converters and 28.5V aviation ground power units (GPUs), our production capacity guarantees dimensional accuracy, thermal dissipation efficiency, and compliance with CE, EMC, and LVD industrial safety directives.

Standard Operating Procedure

Four-Stage Quality-Driven Manufacturing Workflow

Every industrial power unit progresses through documented standard operating procedures (SOPs) designed to ensure mechanical rigidity, high dielectric strength, and long-term operating stability.

1

Cabinet & Busbar Machining

Cold-rolled steel sheets and high-conductivity copper busbars are sheared, punched, drilled, and milled with high-precision machine tools for optimal enclosure fit and minimal contact resistance.

2

Precision Modular Assembly

Trained technicians install IGBT switching modules, high-frequency nanocrystalline transformers, water-cooling heatsinks, and isolated gate driver boards following strict ESD protection protocols.

3

Oscilloscope Waveform Calibration

Digital storage oscilloscopes examine PWM gate driving pulses, output ripple coefficient, phase balance, and voltage transition profiles to verify clean power conversion without harmonic distortion.

4

Full-Load Burn-In Commissioning

Every unit undergoes continuous 100% full-load burn-in at rated voltage and amperage inside our testing bays. Thermal imaging monitors temperature rise across semiconductor junctions and magnetic cores.

Buyer Questions

Frequently Asked Questions Regarding Manufacturing & Quality

Can overseas buyers inspect our production lines or commission units via video?
Yes. Guangdong Fenvix Technology Co., Ltd. regularly facilitates live video factory tours and remote FAT (Factory Acceptance Testing) sessions. Customers can witness their exact ordered equipment undergoing load tests, oscilloscope waveform validation, and thermal camera imaging in real time before approving final shipment.
What is the typical production lead time for custom power supplies and frequency converters?
Standard configuration units generally complete production within 7 to 15 business days. Highly customized, high-power systems (such as 10,000A+ water-cooled rectifiers, 100kV capacitor chargers, or 930kVA aircraft GPUs) require approximately 20 to 30 days depending on component availability and dedicated enclosure fabrication.
How does in-house sheet metal processing benefit international buyers?
By operating our own plate shearing, punching, milling, drilling, and tapping machines, we retain complete control over production schedules and mechanical customizations. This eliminates external subcontracting delays, allows custom footprint adaptations for tight spaces, and guarantees rugged mechanical construction.
What third-party verifications and certifications does our facility hold?
Our production facility operates under an ISO 9001 certified Quality Management System. The workshop and trade capabilities have been audited and verified on-site by TÜV Rheinland. Export products conform to relevant European CE directives, including Low Voltage Directive (LVD) and Electromagnetic Compatibility (EMC), as well as RoHS compliance.
