Quality Assurance

The Quality Assurance Department is our core pride and shoulders the mission of maximizing quality. Based on international certification, combined with advanced measurement technology and strict inspection processes, we ensure that every product can meet or even exceed customer expectations.

International quality certification

We have passed the following two most credible quality management system certifications in the world:

• ISO 9001: a globally accepted quality management system to ensure that our products and services comply with international standards.

• IATF 16949: A quality management system standard developed for the automotive industry, demonstrating our leading position in high precision and high reliability requirements.

These certifications prove our excellence in quality management, process control and continuous improvement, and win the high trust of customers at home and abroad.

Professional measuring equipment

The Quality Assurance Department is equipped with a series of high-precision testing equipment, covering all-round testing needs from tiny sizes to large structural parts:

Rigorous inspection procedures and standards

We have established a comprehensive set of inspection standards, incorporating a four-stage quality control system (IQC, IPQC, FQC, OQC) to ensure that every batch of products undergoes thorough testing and data-driven recording.

1. Incoming Quality Control (IQC)

Upon arrival, all raw materials undergo strict inspections for material composition, dimensions, and appearance to prevent defective materials from entering the production line.

Supplier Evaluation: We regularly assess our suppliers to ensure they consistently meet our quality requirements.

AQL Sampling Standard: We adopt the international Acceptance Quality Limit (AQL) standard for sampling inspections.

Precision Measurement: We utilize precision instruments such as CMMs (Coordinate Measuring Machines) and optical projectors to verify dimensional tolerances.

Material Property Analysis: We validate material composition and physical properties through methods like spectral analysis and hardness testing.

2. In-Process Quality Control (IPQC)

We employ Statistical Process Control (SPC) to continuously monitor the stability of each process, complemented by real-time inspection systems to minimize abnormalities.

First Article Inspection (FAI): Before mass production of each batch, the first product is inspected to confirm it meets all standards.

Self-Inspection: Production line operators are required to conduct self-inspections to identify issues promptly.

Patrol Inspection: Quality assurance personnel regularly patrol all workstations to audit process parameters and operational methods.

Anomaly Management: A standard operating procedure (SOP) is in place for the rapid analysis, handling, and correction of any process anomalies.

3. Final Quality Control (FQC)

Finished products are inspected individually or via sampling for appearance, dimensions, and performance to ensure 100% compliance with customer requirements. Functional testing is strictly controlled to guarantee reliability under extreme conditions.

Reliability Testing: We conduct environmental simulation tests, including drop, vibration, high/low temperature, and salt spray tests, to ensure product durability.

Functional Testing: We perform 100% functional testing on key aspects such as electrical characteristics and mechanical performance.

Full Appearance Inspection: Each product is visually inspected according to established cosmetic standards.

4. Outgoing Quality Control (OQC)

A final random inspection is conducted before products are shipped to ensure the quality of the outgoing shipment.

Packaging Inspection: We verify that the product packaging, labeling, and quantities are correct.

Customer Specification Confirmation: We double-check that the products meet all specific customer requirements.

Inspection Report Consolidation: All inspection records for the batch are compiled to serve as the basis for shipment approval.

5. Customized Inspection Reports

We provide fully transparent inspection reports, including full inspection results, testing data, and suggestions for improvement, to enhance customer trust.

Customizable Report Formats: We can provide inspection reports in specific formats as requested by the client.

Data Traceability: All inspection data is fully documented and traceable.

Continuous Improvement: We provide improvement suggestions based on inspection results and track their implementation and effectiveness.

Data-driven quality improvement

We have introduced an advanced quality management system (QMS) to realize full digital tracking and immediate improvement:

• Automatically record detection data, conduct trend analysis, and prevent problems in advance.

• Continuously improve the quality of products and services through data-driven improvement plans (PDCA).

Professional team and commitment

Our team consists of experienced and internationally certified quality management experts and testing technicians. They not only master the latest technology in the world, but also adhere to the attitude of "keep improving" to provide every customer with services that exceed expectations.
