Stainless Steel Passivation Process: A Key Technology to Enhance Corrosion Resistance of Metal Components​In modern manufacturing, stainless steel parts are widely used in fields such as CNC machining and medical injection molding due to their excellent corrosion resistance and mechanical properties. However, even stainless steel may suffer from surface oxidation or contamination during processing operations like cutting and welding, which reduces its corrosion resistance. The stainless steel passivation process forms a dense oxide film on the metal surface through chemical treatment, effectively isolating external corrosive media and becoming a core technology to improve product lifespan and safety.

What is the Concentricity of Products: The Precision Mystery from CNC Machining to Injection Molding
​In the field of precision manufacturing, concentricity (symbol: ◎) is one of the core indicators for measuring product quality. It refers to the degree of coincidence between the geometric centers of two or more circular features (such as holes, shafts, cavities) and the theoretical axis, directly affecting the assembly accuracy, service life, and performance stability of products. Whether it is the metal parts created by CNC turning services or the plastic components produced by medical injection molding, the control of concentricity is the key to ensuring product reliability

In the modern industrial landscape, 5-axis simultaneous machining has emerged as a core technology that breaks through the bottlenecks in manufacturing complex parts. This technology coordinates the synchronous movement of three linear axes (X, Y, Z) and two rotary axes (A, B/C), enabling the tool or workpiece to be positioned and dynamically cut at any angle in space. It provides disruptive solutions to the high-precision demands of industries such as aerospace, automotive, and medical. High precision CNC machining suppliers play a pivotal role in bringing this advanced technology to the forefront of manufacturing.

In the field of High precision CNC machining, achieving micron - level surface roughness (Ra≤0.4μm) for Custom precision parts is crucial for enhancing the performance and reliability of parts.
