Quality & Certification
Engineered to pass. Built to last.
Every WOERDI® tool moves through a multi-stage quality system covering incoming materials, in-process inspection, finished-product testing and pre-shipment audits. We test what we ship — and document it.

Quality Pillars
Five gates. Zero shortcuts.
Quality is not a final inspection — it is a sequence of checkpoints we refuse to skip, even under deadline pressure.
Incoming Materials (IQC)
Cells, motors, copper, electronics and plastics verified against supplier specs and sampled per batch.
In-Process Inspection (IPQC)
Live audits across motor winding, PACK assembly, molding and final integration lines.
Performance Lab
Torque, RPM, vibration, noise and runtime measured against datasheet under standardized loads.
Environmental Stress
Drop, salt-spray, dust, temperature and humidity cycles for export-ready durability.
Pre-Shipment AQL
Final audit before packing. Reports archived per batch and available to customers on request.
Test Capabilities
A lab inside the factory.
Torque Bench
Calibrated bench for impact and screwdriving spec validation.
BMS Diagnostics
Cell-level monitoring, over-current and over-temperature simulation.
Battery Cycling
Charge / discharge cycling to validate runtime and longevity.
Thermal Chambers
Operation tested from −10 °C to +50 °C ambient.
Vibration & Drop
Drop testing from working height; simulated jobsite vibration profiles.
Material Inspection
Plastic, gear and bearing inspection under magnification.
Safety Validation
Insulation, leakage, EMC pre-check on every new design.
AQL Sampling
Standardized acceptance quality limits per shipment and per SKU.
Certifications
Compliance, anywhere.
We manage labs and submissions in-house — your products clear customs and retail audits without surprises.
