Engineered for High Precision, Scaled for Demanding Industries
Guangdong Fenvix Technology Co., Ltd. maintains a vertically integrated production infrastructure in Guangdong, China. From initial heavy-gauge sheet metal stamping and copper busbar fabrication to high-frequency transformer winding and precision PCB surface-mount integration, our factory manages each engineering phase under stringent ISO 9001 quality management standards.
Unlike trading contractors, our completely self-reliant workshop guarantees absolute thermal stability, component traceability, and electrical conformity across all non-standard power units. Global industrial partners trust our proven capabilities in developing heavy-current electroplating rectifiers, high-voltage test supplies, and solid-state aviation ground power equipment.
Fabrication & Mechanical Processing Facilities
Our workshop is equipped with industrial metalworking and finishing machinery to construct heavy enclosures, high-current copper interconnects, and corrosion-resistant chassis tailored for electroplating environments.
Plate Shearing Machine
Heavy-duty hydraulic plate shearing allows rapid and precise cutting of sheet steel and aluminum alloys used for high-rigidity rectifier cabinets and sealed chassis.
Punching Machine
High-tonnage stamping and punching processes create ventilation slots, mounting louvers, and connector ports with consistent dimensional tolerances and clean edges.
Milling Machine
High-torque milling equipment accurately cuts thermal heat-sink surfaces and massive solid-copper conductors to eliminate contact resistance in high-ampere rectifier units.
Drilling Machine
Dedicated multi-head drill units establish accurate structural mounting apertures and ground bolt positions to guarantee cabinet structural integrity under continuous industrial duty.
Tapping Machine
High-speed, torque-monitored tapping systems process threaded connections across busbar blocks, water-cooling plates, and rack rails to prevent thread stripping under severe vibration.
Finished Rectifier Cabinets
Completed structural cabinets undergo multi-stage epoxy powder coating to deliver robust acid and alkali resistance, tailored specifically for aggressive electroplating line environments.
Multi-Stage Assembly & Quality Control
Every industrial power module built by Guangdong Fenvix Technology Co., Ltd. moves through sequential, standardized assembly gates to eliminate latent defects and ensure flawless operation.
Assembly Process 1: Module Integration
Technicians secure high-power IGBT modules, isolation transformers, and proprietary driver boards onto vibration-dampened sub-chassis frames with precision calibrated torque drivers.
Assembly Process 2: Interconnects & Harnessing
Installation of solid silver-plated or nickel-plated copper conductors, high-frequency filter capacitors, and noise-isolated communication wiring harnesses for PLC/RS485 modules.
Assembly Process 3: Cooling & Cabinet Finalization
Integration of water-cooling manifold loops or variable-speed industrial blower fans, complete with safety interlocking microswitches, current shunts, and clear digital meter displays.
Incoming Material Inspection
Rigorous verification of raw copper, IGBTs, diodes, capacitors, and microcontrollers to weed out non-conforming parts before production.
Chassis Mechanical Build
Precision punching, bending, tapping, and corrosion-resistant powder coating of heavy modular cabinet frames.
Electrical Assembly & Wiring
Systematic wiring of high-current power stages, driver control logic, and EMC-shielded low-voltage sensor harnesses.
Burn-In & Load Verification
100% full-load thermal stress testing and multi-hour burn-in cycles to ensure zero field failures for global industrial clients.
Comprehensive Testing, Commissioning & QA
No power system leaves our factory without exhaustive electronic wave validation, full dynamic load testing, and insulation withstand verification.
Full System Commissioning
Commissioning engineers configure firmware parameters, calibrate digital current/voltage readouts, adjust PID loop response rates, and simulate over-current, over-voltage, and thermal trip routines under working conditions.
Oscilloscope Waveform & Ripple Testing
Using high-bandwidth digital oscilloscopes and precision current probes, technicians verify IGBT switching rise/fall times, eliminate dead-time ringing, and confirm ripple factors meet specified tolerances.
