A practical factory process, close to the shipment.
PartDorin operates from an 8,000 m² facility in Shenzhen. We focus on the checkpoints that help buyers prepare component requirements, review packing and reduce surprises before export.
Discuss Your Requirements
Production that stays connected to the part.
For automotive components, production control starts with recognizable product details. Teams work from the agreed application, reference and handling requirements rather than treating every part as interchangeable.
Inspection is part of the handoff.
A practical automotive-parts process needs more than a production schedule. We work through product identity, relevant requirements, packing condition and shipment-ready information with the detail level agreed for your order.
- Incoming material and part identity checks
- In-process inspection for assigned requirements
- Final shipment inspection before export packing


Customer requirements translated into shop-floor checkpoints.
A brake-component request may arrive with an OE number, sample, drawing, packaging requirement or target application. Before work begins, the useful question is which details need to travel with the order.
- Requirement
- Align the relevant reference, dimensional focus and requested packaging.
- Coordination
- Use the sample or drawing to guide internal preparation and inspection points.
- Handoff
- Confirm the agreed product identity and presentation before shipment release.
Documents matched to the project.
We do not use generic compliance language as a substitute for buyer requirements. During qualification, ask us which quality-system documents, material records, inspection reports or product-specific certificates are applicable to your requested parts.
- Quality-system and factory documentation
- Material, test and inspection records where applicable
- Product-specific compliance documents on request
