We are equipped with a full set of high-precision inspection equipment and a professional quality inspection team to provide comprehensive quality control support for our products. The main inspection equipment includes:<\/p>

Coordinate Measuring Machine (CMM): Used for high-precision dimension detection of precision parts, with an error range of \u00b10.005mm, which can accurately measure the geometric dimensions, surface roughness and other key indicators of the parts, ensuring the accuracy of product size.<\/p>

Vision Measuring Instrument: It is used to detect the surface finish, edge smoothness and structural integrity of parts, and record the inspection data in real time to ensure the consistency of each batch of products.<\/p>

Hardness Tester: Used to detect the hardness of parts, match the material performance requirements, and ensure that the parts can meet the application needs of different scenarios such as automotive and medical.<\/p>

Surface Roughness Tester: It is used to detect the surface finish of parts, avoid surface defects such as burrs and scratches, and ensure the surface quality of products.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Raw Material Inspection<\/a><\/h4>

For the raw materials entering the factory, we will conduct strict incoming inspection, verify the material composition and performance through professional testing equipment, and only the qualified raw materials can enter the production link.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t

First Article Inspection<\/a><\/h4>

Before mass production, we will conduct a full inspection of the first article of the product, confirm the dimensional accuracy, surface quality and other indicators, and start mass production only after passing the inspection.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t
