Automotive Mold Quality Management System

Through systematic control include design, manufacturing, and validation—combined with advanced inspection technologies—we ensure every delivered automotive mold is reliable, precise, and durable.

Quality Management for Automotive Mould

At SINO, quality is the responsibility of every employee. Our “Zero Defects” philosophy is embedded in every stage of the mold lifecycle, building an impregnable line of quality defense through scientific, rigorous, and traceable measures.

Source:
Strategic-Level Raw Material Control

We have established strategic partnerships with world-leading steel mills such as Baosteel and Thyssenkrupp to ensure excellent quality at the material source. All incoming raw materials must pass 12 stringent inspections, including spectral analysis, hardness testing, and ultrasonic flaw detection. A quality record is created for each material, tracing it from the steel mill to the finished mold, laying the foundation for long life and high stability in terms of both physical and chemical properties.

Process:
Digitalization & Statistical Process Control (SPC)

During production, we establish Key Control Points (KCP) for critical processes. First Article Inspection (FAI) is performed after each step. More importantly, we extensively apply Statistical Process Control (SPC) methods for real-time monitoring and trend analysis of machining dimensions, achieving a shift from “post-process inspection” to “preventive control,” ensuring process stability and precision.

Final Inspection:
Comprehensive Validation Based on Data & Empirical Evidence

Before mold delivery, it must pass three ultimate tests:

1.Full digital dimensional inspection (CMM);

2.Empirical mold trial validation (continuous production of 500 sample parts for dimensional consistency analysis and CpK calculation);

3. Mold action simulation testing. Only when all data and sample parts 100% meet the customer’s technical specification requirements is the mold approved for shipment.

After-Sales:
Lifelong Maintenance & Customer-Driven Improvement

The end of quality management is not delivery. We establish a lifelong quality record for each mold and proactively conduct regular customer follow-ups on usage. We provide lifelong maintenance services, and each service execution follows a “one service, one evaluation” mechanism. It is this closed loop management oriented towards customer satisfaction that has maintained our customer satisfaction score above 95 (out of 100) for five consecutive years and drives our continuous improvement.

Controllable Risk

Prevention and inspection throughout the entire process minimize quality risks, safeguarding your project timelines.

Optimal Cost

High-precision and high-stability molds directly reduce your production defect rates and maintenance costs.

Sustainable Trust

Transparent data, empirical validation, and lifelong service provide you with a long-term, stable partner.
