Description

CNC Milling Stainless Steel Parts Machined As Machined After machining, stainless steel parts maintain their original state. At MQJM, a surface roughness of 125 Ra or better can be achieved and further improved through finishing passes. For stainless steel parts, visible tool marks and sharp edges can be removed upon request.

CNC Milling Stainless Steel Parts Polishing Polishing Achieve a smooth and glossy surface on stainless steel through manual polishing in multiple directions or the application of a chemical polish treatment. Polishing not only enhances the aesthetic appeal of metalwork but also strengthens stainless steel's resistance to harsh environments. Additionally, polishing plays a crucial role in shaping the mold and manufacturing the final product using the polished mold.

CNC Milling Stainless Steel Parts Nickel Plating Nickel Plating Nickel plating has two common types: decorative nickel (bright nickel) is mainly used for aesthetic decoration, while electroless nickel (chemical immersion nickel) is suitable for mechanical parts requiring corrosion resistance. The cost of these two coatings almost doubles, with decorative nickel commonly used for general decoration and electroless nickel for mechanical components with higher corrosion resistance requirements.

CNC Milling Stainless Steel Parts Blacked Blacked Blackening treatment is widely applied to various tool components, aiming to enhance product corrosion resistance while maintaining precision. This treatment method is commonly seen in different tool parts, providing them with increased corrosion resistance and ensuring excellent performance and longevity in various environmental conditions.

CNC Milling Stainless Steel Parts Plating Plating Stainless steel electroplating is a process that involves applying an electric current to deposit a metal coating onto the surface of stainless steel. This can include various electroplating methods for stainless steel, such as chrome or zinc plating, aimed at improving appearance, enhancing corrosion resistance, or adding specific properties.

CNC Milling Stainless Steel Parts QPQ Treatment QPQ The QPQ treatment is a process designed for stainless steel components, involving two key steps: carbonitriding and high-temperature oxidation. By introducing nitrogen and carbon, a robust nitriding layer is formed to enhance the hardness and wear resistance of the components. Subsequent high-temperature oxidation further enhances corrosion resistance.

CNC Milling Stainless Steel Parts PVD (Physical Vapor Deposition) PVD PVD (Physical Vapor Deposition) is an advanced surface treatment technology that deposits thin films onto stainless steel parts in a vacuum environment, altering their appearance, hardness, and corrosion resistance. Stainless steel parts treated with PVD typically exhibit a bright appearance, exceptional hardness, and increased wear resistance.
