Case Presentation

LY believes that in the new product development stage, the core of CNC customized machining lies in ensuring that the structural design is economically reasonable, the process flow is finely planned, and the materials and surface treatment are accurately selected to lay the foundation for quality and ultimately achieve efficient and worry free machining.

Metal surface treatment is a key process to improve the performance and appearance of metal parts. In the CNC finishing stage, proper surface treatment can not only enhance the physical properties of the metal, but also significantly enhance its market competitiveness. The following is an optimized version of the article content you provided:

Metal Surface Treatment: Enhanced Performance, Improved Appearance

In the manufacturing industry, surface treatment of metal parts is an important means of improving product durability and appeal. By changing the external characteristics of metals, such as color, gloss, corrosion resistance and hardness, we can add unique selling points to products.

Defining Surface Treatment

Surface treatment is a value-added process that specifically adjusts the external properties of a metal part. This includes processes that remove material (such as grinding) and add material (such as coating) to achieve the desired performance and appearance effects.

Importance of Surface Preparation

The surface condition of a metal component is critical to its overall quality and performance. It not only affects the bonding and coating capabilities of the component, but also determines its surface texture, conductivity, and cleanliness. These characteristics are critical to the function and durability of the component.

Application examples of surface treatment

Enhanced gloss: In the automotive industry, chrome-plated engine parts, brightly colored grilles and hubcaps are all surface treatments used to enhance the appearance and appeal of products.

Increased Hardness: By hardening the surface of a metal, you can significantly increase the component’s service life and ability to withstand daily use. For example, case-hardened nails and gears are better able to withstand heavy impacts and hot engine conditions.

Improved corrosion resistance: Surface treatments can also improve the corrosion resistance of metals in harsh environments, thereby extending the service life of components.

Our Service Advantages

YL provides comprehensive metal finishing services, including:

Mechanical processing: such as honing, grinding and milling to improve the size and surface roughness of metal parts.

Heat treatment: including annealing to improve the strength, hardness and corrosion resistance of metal parts.

Other surface treatment: including electrophoretic coating, TiN coating, laser engraving and galvanizing, etc., to meet customers’ specific needs for the appearance and performance of metal parts.

Four important surface treatment operations

Electrophoretic coating: by immersing the metal workpiece in a charged paint bath, the charge is used to make the paint adhere to the part to form a hard, bright coating.

TiN coating: a layer of titanium nitride is applied to the metal surface to form a beautiful and very hard shell.

Laser engraving: using lasers to leave permanent marks or decorations on the workpiece, such as serial numbers.

Galvanizing: a layer of zinc is covered on the surface of steel or other base metals to protect it from corrosion.

Through these surface treatment technologies, we can provide customized solutions for your metal parts to meet specific performance and aesthetic requirements. Choose our services to enhance the competitiveness of your products in the market!
