Defined checkpoints from incoming parts to packed goods.

Quality control is organized as a traceable five-stage system, supported by torque, function, durability and shipment checks.

Five-stage control

Prevent issues early.
Verify every release.

Checks are positioned where they can prevent defects, confirm performance and protect the shipment—not only at final packing.

Motors, batteries, PCBs, S2 / CR-V bits, plastic and metal parts are checked before production.

Supplier qualification · AQL sampling · rejection control

Assembly accuracy, torque calibration, process parameters and operator standards are monitored through production.

Real-time checks · abnormality correction · traceable records

Finished units receive torque, function, appearance and noise checks, with durability sampling as required.

100% core function checks · appearance · performance

Continuous operation, temperature, drop and life-cycle testing simulate real operating and shipping conditions.

Aging · high / low temperature · drop · cycle life

Packaging integrity, labels, barcode, quantities and final samples are verified before dispatch.

Pack integrity · identification · quantity · final sample

Compliance support

The supplied company materials list CE, FCC and RoHS compliance. Applicability and product-specific reports should be confirmed for each order.
