Surface treatment ability

Anodizing can improve corrosion resistance, enhance wear resistance and hardness, and protect metal surfaces. Widely used in mechanical parts, airplanes, auto parts, precision instruments, etc.

Electroplating can be functional, decorative or corrosion related. Many industries use this process, including the automotive industry, where chrome plating of automotive steel parts is common.

Sandblasting will make the surface of the part smooth and rough texture. Mainly used for vision applications, then other surface treatments can be performed.

Polishing is the process of creating a smooth and shiny surface through physical friction or chemical interference of parts. The surface produced by this process has obvious specular reflection, but diffuse reflection can be reduced in some materials.

Polishing Image

Brushing is a surface treatment process in which, usually for aesthetic purposes, an abrasive belt is used to draw marks on the surface of the material. Most commonly used in aluminum。

Brushing Image

The powder coating forms a durable, wear-resistant and corrosion-resistant layer on the surface of the part. Powder coatings can be used to apply color to parts and are compatible with any metal.

Painting the surface of parts can improve their aesthetic appearance and can provide consumers with brand awareness. In addition, painting may have a protective effect on the parts.

High-end finishes made using diamond polishing technology can produce a shiny surface.

Grade B finishes are polished with sandpaper to produce parts that are slightly rougher than Grade A finishes. Products that have undergone B-level finishing have rough surface textures.

Semi-Glossy Finish Image

Grade C finishes use gravel polished stones to produce a rough, uneven surface. C-level finishing products have rough surface texture。

Matte Image

Class D finishes use coarse sand and dry glass beads or oxides to make very rough finishes. Depending on the type of material used, the product can have a satin or dull finish.

Textured Finish Image

Screen printing is a printing technique in which a net is used to transfer ink to a substrate, except in areas where the ink is impermeable through a closed template.

Quality report and certification

Full size inspection

Comprehensive inspection report

For each order on our platform, we will provide the customer's complete size inspection report & # 8217; request. Use precision measuring instruments (calipers or gauges) and use coordinate measuring machines to verify dimensions when needed. The report includes:

  • Number of parts
  • Key dimensions
  • Threads and tolerances
  • thickness and depth
  • Part appearance
Magnesium alloy material certification

Material certification

According to customer requirements, we can provide certification of materials used in the manufacturing process. The report comes from the raw material manufacturer and usually includes:

  • Material calorific value
  • Material grade
  • Material size
  • Mechanical characteristics
  • Chemical analysis
  • Heat treatment (if applicable)
