Incoming parts
Motors, switches, cells, PCBs, housings and gearboxes are checked by lot before release to the line.
Manufacturing & quality control
Manufacturing discipline built into every cordless tool.
From incoming components to final packing, VoltForge keeps production, testing and export documentation on the same line of sight.
One integrated operation
Production facilities, quality gates and export readiness under one roof.
Our Ningbo operation combines cordless-tool assembly, motor matching, battery testing, in-process inspection, aging, packaging and technical support for OEM programs.
28Ksqm facility
12assembly lines
4quality gates
24hRFQ response
Production system
From component matching to shipment-ready cartons.
Each stage is set up around cordless-tool repeatability, safe battery handling and reliable retail presentation.
Assembly & calibration
Fixtures, torque tools and work instructions keep core assembly steps stable across each batch.
Load & aging
Finished tools, batteries and chargers move through functional, load, heat and charging checks.
Packing & release
Accessories, labels, manuals, cartons, barcodes and pallet marks are verified before shipment.
Walk the operation

A factory review can cover the line, motor cell, aging rack, test room, packaging stations and engineering office.
- Final assembly for drills, drivers, grinders and charger kits
- Brushless motor balancing and battery-pack preparation
- Live review of inspection records, packaging and shipment labels
Four quality gates
Quality control follows every batch from incoming parts to outgoing inspection.
Measured checkpoints protect tool performance, battery stability, packaging accuracy and traceability.
IQC
Incoming component inspection
Motor, switch, battery cell, charger PCB, housing and gearbox lots are checked before line release.
IPQC
In-process line control
Torque, speed, clutch function, trigger response and battery contact stability are checked at key assembly stations.
AGING
Load, heat and battery cycling
Finished tools run under work-like load; batteries are charged, discharged and checked for voltage drift.
OQC
Outgoing AQL inspection
Appearance, accessories, label, carton, barcode and random functional tests are completed before loading.
Key test points
Tests tied to performance, safety and shipment condition.
Test records are matched with the model, battery pack, charger and packaging configuration.
| Test item | What is checked | Typical record |
|---|---|---|
| Torque & speed | Output curve, speed setting, trigger and clutch response | Torque curve and functional result |
| Battery protection | Over-current, over-charge, over-discharge, temperature and short-circuit protection | BMS test report |
| Tool & carton drop | Tool retention, tray protection and carton corner strength | 1.2 m drop-test record |
| Charger safety | Charge behavior, plug route, heat rise and labelling | Charger check sheet |
| Outgoing packing | Manual, accessories, barcode, carton mark and pallet label | Pre-shipment photo set |
Sample quality report
Batch records ready for technical and purchasing review.
A typical report links model, batch, quantity, test items, pass/fail results, packaging records and photo evidence.
Release control
Issues resolved before shipment release.
When a control point does not meet the agreed standard, the batch stays at the station until it is corrected and rechecked.
Hold
Torque drift
Output falls below the approved curve after load testing; line calibration is required before release.
Hold
Battery contact gap
Vibration reveals intermittent power; spring pressure and housing tolerance are reviewed.
Hold
Carton damage
Corner crush after drop testing; inner tray and carton structure are adjusted before mass packing.
Hold
Label mismatch
Manual language or charger label does not match the agreed market documentation.
Engineering & export team
Product, packaging and documents reviewed together.
Export sales, engineers and quality personnel work from the same product configuration before a sample or production run is released.
