How Orders Are Reviewed
01
Confirm the product family and order target.
02
Check whether the required structure fits current tooling and process control.
03
Then move to sample checking or repeat supply.
Process control
Production review is based on actual factory process, not only catalog wording.
Inspection checkpoints
Profile, tension, and surface condition are checked before release.
Repeat supply
Sample approval and repeat orders follow the same process.
Factory & QC | Industrial Belt Production and Inspection | INJ
Production areas
Rubber belt molding and vulcanization, PU timing belt processing, belt cutting and finishing, and timing pulley machining where applicable — organized for repeat industrial supply.
Inspection steps
Incoming material inspection, dimension checks, tensile/tension testing, surface and tooth profile review, final packing inspection, and batch traceability before release.
Pre-shipment confirmation
Before shipment, we check belt model, width, length, surface condition, marking, packing, and quantity according to the customer's order. For distributors, consistent quality is more important than one-time low price.
The practical value is simple: fewer surprises during sampling, clearer communication during technical review, and more confidence when an order moves from prototype to repeat production.
