Injection Molding Surface Finishes
SOMI offers a diverse range of surface finishes, each tailored to meet the specific needs of your projects. Here's a closer look at some of the options.
As-machined
The standard finish of our parts, the "machined" finish, has a surface roughness of 3.2 μm (126 μin), which removes sharp edges and cleanly removes burrs from the part.
Machining Texture:There are slight scratches on the visible surface.
Smooth machining
A finishing CNC machining operation can be applied to the part to reduce its surface roughness. The standard smoothing surface roughness is Ra 1.6 μm (64 μin). Light surface scratches are visible.
Machining Texture:Visible, light surface scratches.
Fine machining
Refers to the process of precision treatment of raw materials or semi-finished products. The standard smoothing surface roughness is Ra 0.8 μm (32 μin).
Machining Texture:Slightly visible.
Bead blasting
Bead blasting refers to the use of round spherical media that, when impacted against the surface of a part, will leave a more uniform finish caused by the sphere “dimpling” the surface.
Machining Texture:Frosted grain.
Brushing
Brushing is a surface treatment process that uses abrasive belts to draw traces on the surface of a material, usually for aesthetic purposes.
Polishing
From Ra 0.8 to Ra0.1, the polishing process uses abrasive materials to rub the surface of the part, making the surface of the part more shiny, depending on your requirements.
Machining Texture:Smooth, glossy finish
Anodizing
Aluminum and its alloy in the corresponding electrolyte and specific process conditions, due to the action of external current, the process of forming an oxide film on the aluminum product.
Machining Texture:Smooth, matte finish.
Electroplating
Electroplated coating preserves the surface of parts and resists rusts and other defects from causing decay by applying electric currents to reduce metal cations.
Machining Texture:Smooth, glossy finish.
Electroless nickel plating
Electroless nickel plating is a process that deposits an alloy of nickel-phosphorus onto the surface of a metal. This process is chemical only, so does not involve the use of electricity.
Machining Texture:Reduced but visible.
Black oxide
Black oxide is a conversion coating similar to Alodine that is used for steel and stainless steel. It is used mainly for appearance and for mild corrosion resistance..
Machining Texture:Smooth, matte.
Powder coating
Using corona discharge, we make the powder coating adsorbed to the part, creating a more wear-resistant layer with a typical thickness ranging from 50 μm up to 150 μm.
Machining Texture:Glossy.
Chromate conversion coating
Chromate conversion coating is a type of conversion coating, used on aluminum as a corrosion inhibitor, as a primer for paint due to increased adherence or to preserve electrical conductivity.
Machining Texture:Visible.
Electrophoresis
In the solution under the action of direct current electric field, the charged resin moves to the opposite electrode phenomenon. Strong corrosion resistance, can be on different colors.
Machining Texture:Visible.

Frequently Asked Questions
If you have any further questions, please contact us. We look forward to working with you.
- Q: What is injection molding?A: Injection molding is a manufacturing process used to produce parts by injecting molten material into a mold. It is commonly used with plastics but can also accommodate metals, glasses, and elastomers. The process begins with melting the material, which is then injected under pressure into a mold cavity. Once the material cools and solidifies, the mold is opened to eject the finished part. This technique is favored for its ability to produce large volumes of identical parts with high precision, complex shapes, and excellent surface finish. Injection molding is efficient and cost-effective, particularly suitable for mass production.
- Q: What is the difference between plastic injection molding and 3D printing?A: 3D printing is better for small batch, complex parts that may require frequent design changes or customisation. Injection moulding, on the other hand, is better for large volume production of less complex parts that have successfully completed the design stage.
- Q: What is the main advantage of plastic injection compared to additive manufacturing?A: The main advantage of injection molding compared to additive manufacturing is the production of large volumes of identical parts. However, injection molding faces significant challenges, notably in setup time and initial investment.
