Quality Management
Quality Management Precision Through Process. Trust Through Traceability.
Quality is Beyond One-Time Inspection, a Continuous Commitment in Every Step! At MATECH, quality is not just a checkpoint, it’s a promise embedded in every stage of production. Our end-to-end quality management system, with ISO 9001:2015 certified, ensures that every process (from incoming raw materials to final product delivery) is strictly controlled. Each batch of products is fully traceable to its raw material furnace number, production records, and inspection data, guaranteeing that every component you receive is consistent, reliable, and verifiable.
Quality Policy
Sincerity· Quality · Competence· Enterprising
Put customers first, consistently meet and surpass customer expectations.
Managing quality systematically through a process-driven approach, ensuring every procedure is under control.
Driving continuous improvement with real data, enhancing product consistency and reliability.
Engaging all employees to foster a culture of excellence in quality.
Full-Process Quality Control System
MATECH enforces rigorous quality management across every stage of production, without compromise.
Every raw material undergoes strict inspection and is only accepted into inventory if it meets customer standards.
| Inspection Item | Equipment / Method | Acceptance Criteria |
| Chemical Composition | Spectrometer, carbon-silicon analyzer, chemical composition testing platform | Meet customer-specified standards (ASTM, DIN, GB, etc.) |
| Mechanical Properties | Universal testing machine, hardness tester | Tensile strength, yield strength, elongation, hardness |
| Material Certificate | Review MTC from materials Supplier | Traceable to furnace number, supports third-party re-inspection |
During the manufacturing process, deviations are promptly identified and corrected through a combination of first article inspection, operator self-inspection, and in-process patrol inspection.
First Article Inspection (FAI): The first part of every batch and every process must undergo full-dimensional inspection. After it’s qualified, mass production can begin. Operator Self-Inspection: Operators measure and record critical dimensions in accordance with work instructions. In-Process Patrol Inspection: Dedicated quality inspectors perform sampling inspections at defined intervals, to monitor process stability. SPC (Statistical Process Control): Control charts are established for critical characteristics (such as hole diameter and flatness), with process capability maintained at CpK ≥ 1.33.All inspection data is recorded in real time within the quality management system. In the event of abnormalities, alerts are triggered and corrective and preventive actions (CAPA) are implemented promptly.
Before shipment, finished products undergo 100% or batch sampling inspection. Types of inspection include:
100% Critical Dimension Inspection: Each part is individually measured for customer-specified critical features, with all data recorded for traceability.
| Inspection Type | Inspection Content | Equipment |
| Full-Dimension Inspection | Length, diameter, angles, threads, and all drawing dimensions | Coordinate Measuring Machine (CMM), height gauge, micrometer, projector measuring instrument |
| Geometric Tolerance Inspection | Flatness, roundness, concentricity, position tolerance | CMM, roundness tester, contour measuring instrument |
| Surface Quality Inspection | Surface roughness, appearance defects, color difference | Roughness tester, visual inspection, colorimeter |
| Hardness Testing | Overall hardness, case depth | Rockwell / Brinell / Vickers hardness testers, PS analyzer |
| Special Testing (as Required) | Airtightness, salt spray resistance, non-destructive testing | Airtightness testing bench, salt spray chamber, ultrasonic / magnetic particle flaw detector, penetrant testing (PT) equipment |
Matech Quality Traceability System
Matech has established a comprehensive product traceability system, enabling bidirectional traceability for every production batch.
Forward Traceability: Raw material batch number → Production batch → Processing records → Inspection data → Shipment order number
Backward Traceability: Shipment order number → Inspection reports → Machine operators → Raw material batch
Traceable Information Includes:
• Raw material certificate number
• Casting / heat treatment process parameters
• CNC program number, operator, and equipment ID
• Inspectors, testing equipment, and measured values
• Shipment date, packaging method, and logistics tracking number
Traceability records are retained for a minimum of 10 years, and are available for internal verification or customer review at any time.
Continuous Improvement & Customer Feedback
Quality improvement is not a one-time task but a daily management habit.
•Corrective and Preventive Actions (CAPA): For any internal or external quality issues, conduct 8D or 5‑Why analysis, implement corrective actions, and deploy them across relevant departments.
• Management Review: Led monthly by core management, reviewing quality objectives, evaluating past performance, and planning improvement initiatives.
• Customer Satisfaction Surveys: Regularly collect customer feedback and convert the voice of the customer into internal improvement projects.
• Employee Quality Proposals: Encourage frontline employees to submit improvement suggestions and reward valuable contributions.
Our Quality Commitment
At Matech, every employee is both accountable for and a contributor to quality. We believe that only by embedding quality awareness into every operational detail, can we deliver products that withstand the test of time.
We are committed to:
• Every drawing is thoroughly reviewed.
• Every material batch undergoes composition verification.
• Every process step is controlled and traceable.
• Every production batch is strictly inspected.
• Every customer receives an inspection report for delivered products.
