Surface Finishes
Available Surface Finishes for You Choosing
Part surfacing finishing techniques can either be for functional or aesthetic purposes. Each technique has requirements, such as materials, color, texture, and price. Below are the specifications of the plastic finishing techniques rendered by us.

CNC Machining Metals
It creates a linear pattern with a consistent and uniform texture on your part’s surface. Suitable for architectural components and automotive parts.
Parts are bead blasted with glass beads which results in a grainy texture and reduced machining marks.
Powder coating is a strong, wear-resistant finish that is compatible with all metal materials.
Conversion coating forms a magnetite layer on the material’s surface, providing a dark, matte black finish. Its process involves dipping the metal part into a hot solution of blackening chemicals, followed by rinsing and oiling to seal the surface.
A uniform finish demonstrating excellent wear and corrosion resistance properties is produced by depositing a nickel-phosphorus alloy onto a material without an electrical current. The surface obtained is hard and lubricious, providing outstanding electrical conductivity.
Parts are bead blasted, anodized type II and bright dipped. Results in glossy color. Ideal for cosmetic parts needing an increase in corrosion resistance.
Parts are anodized (type II) directly after machining. The most cost-effective anodizing option; ideal for non-cosmetic, functional parts. Used to improve wear and corrosion resistance.
Brushing the material to create a uniform directional grain, followed by anodizing it with a glossy finish. It creates a hard, wear-resistant oxide layer on your part’s surface to enhance its durability and corrosion resistance.
Bead blasting followed by anodizing (type II) matte surface finishing to create a uniform matte finish. It provides excellent wear and corrosion resistance to your CNC machined parts and improves their surface hardness.
By anodizing the surface of your as-machined parts from CNC milling, CNC turning, or 2-, 3-, or 5-axis CNC machining with type III anodization, a thick and durable oxide layer is created that offers exceptional resistance to abrasion, corrosion, and chemical damage.
A combination of brushing and electropolishing creates a uniform directional pattern with a surface roughness of Ra 0.8μm or Ra 32μin. It’s ideal for applications that require a high degree of surface finish, such as medical equipment, aerospace components, and semiconductor manufacturing.
Through a chemical conversion process, metals such as aluminum and magnesium are coated with a thin, protective film that bestows superior corrosion resistance and enhances adhesion for subsequent coatings of your CNC machining parts.
Injection Molding Plastics
The SPI grade A1, A2, and A3 surface finishes are made with diamond buffing for a glossy and shiny surface finish.
The SPI standard B1, B2, and B3 grade surface treatment uses grit sandpaper paper to yield a semi-glossy surface finish.
The C1, C2, and C3 SPI grade surface treatments use grit sanding stones to achieve rough texture and uneven surface.
D1, D2, and D3 grade treatments use dry blast glass beads, and oxides for the surface finish to produce a very coarse and textured surface.
Sheet Metal Fabrication
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.
Bombarding a material’s surface with tiny glass beads or ceramic particles results in a uniform, matte finish that can eliminate surface imperfections and machine marks while simultaneously improving the part’s resistance to wear and corrosion.
To create a robust and uniform coating, dry powder is applied to the material and baked at high temperatures. This process endows the parts with superb resistance to corrosion, chipping, and fading. Depending on the type of powder, the texture of the coating can be either glossy or matte.
