Our Quality Control Measures

Raw Material Procurement: We rigorously select suppliers to ensure the quality and consistency of raw materials. We also conduct random inspections on raw materials to comply with national standards and customer needs.

Production Process Control: We effectively control the production process using methods similar to those for auto parts, developing production control documents for Product Part Approval Process (PPAP) to ensure process stability and uniformity. We monitor and record critical stages during production to ensure product quality meets standards.

Product Inspection: We utilize advanced heat treatment inspection equipment and methods to test metallography, hardness, etc. We use ultrasonic non-destructive testing to identify cracks in raw materials and subsequent processing, covering appearance, performance, and safety of products. Only products that pass these tests are allowed to be delivered to our customers.

Quality Management System Certification: We meet and exceed the requirements stated in the ISO 9001: 2015 quality manual, and established a comprehensive quality management system to ensure the stability and reliability of product quality and services.

Through these measures, we can produce quality products and we will continuously improve product quality and service levels to exceed expectation of customers worldwide!
