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.
