Surface Finishing Capabilities

Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.

Anodizing Image

Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.

Electroplating Image

Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.

Bead blasting Image

Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.

Polishing Image

Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. Most commonly applied to aluminum.

Brushing Image

Powder coating forms a durable, wear resistant and corrosion resistant layer on the surface of parts. Powder coating can be used to apply colors to parts and is compatible with any metal.

Powder Coating Image

Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.

Painting Image

A grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces.

Glossy Finish Image

B grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Products that undergo B grade finishing have a matte surface texture.

Semi-Glossy Finish Image

C grade finishes use grit sanding stones to produce a rough, uneven surface. Products that undergo C grade finishing have a matte surface texture.

Matte Image

D grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish.

Textured Finish Image

Screen printing is a printing technique where a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil.

Quality Reports & Certifications

full dimension inspection

Full Dimensional Inspection Report

For every order on our platform, we provide a full dimensional inspection report on customers’ request. Dimensions are verified using a precision measuring instrument (caliper or gauge) and with a Coordinate Measuring Machine when required. The report includes:

  • Quantity of parts
  • Critical dimensions
  • Threads and tolerances
  • Thicknesses and depths
  • Part appearance
material certification

Material certification

On the request of customers, we can provide the certification of the material used in the manufacturing process. The report comes from the raw material manufacturer and usually includes:

  • Material heat number
  • Material grade
  • Material dimensions
  • Mechanical properties
  • Chemical analysis
  • Heat treatment (if applicable)
