Xinhaisen Technology Limited: Rigorous Quality Control from Raw Materials to Delivery
Xinhaisen Technology Limited implements a meticulous, certification-driven quality management system aligned with ISO 9001, ISO 14001, and IATF 16949 standards, ensuring excellence at every stage:
1.Material Sourcing & Inspection:
- All raw materials (stainless steel, copper alloys, etc.) are sourced from certified suppliers, with batch-specific chemical composition verification via XRF spectroscopy.
- Compliance with RoHS/REACH and material traceability documentation are strictly enforced.
2.In-Process Control:
- Real-time monitoring of critical parameters (e.g., etching depth, welding temperature) using automated systems and statistical process control (SPC) tools.
- Dimensional accuracy checks with optical comparators and CMMs (Coordinate Measuring Machines) at defined intervals.
3.Final Product Verification:
- 100% functional testing (e.g., tensile strength, leak tests) and visual inspection per customer specifications.
- IATF 16949-compliant PPAP (Production Part Approval Process) for automotive components.
4.Packaging & Shipping:
- Anti-corrosion treatments and customized packaging to prevent transit damage.
- Final audit with quality certificates and full documentation (COC, material reports) included.
5.Continuous Improvement:
- Closed-loop corrective actions (CAPA) based on defect analysis and customer feedback.
- Eco-conscious practices (ISO 14001) minimize waste and energy consumption.
Our integrated ERP/MES systems ensure full traceability, while dedicated QA teams guarantee that every product meets global regulatory and performance benchmarks.
