· Standard/As manufactured

The standard finish of any part is the basic cosmetic appearance of the part immediately it is manufactured. It refers to the state of the part when ejected, machined, printed, or cast. This finish will have visible tooling marks, resin, or powder remnants as applicable to the production method.

It is suitable for parts that will form a bigger machine's inner components and will be situated in areas where they do not contribute to the overall cosmetic appearance of the piece.

· Bead Blasting

Bead blasting involves the application of glass beads to specific parts with the aid of a high-pressure technique without damaging the surface of the project. Our bead blasting process can also be used to remove machine marks, scratches and other scars and obtain a uniform process in a short period of time.

Machined, 3D-printed, Extruded, Die-casted, or Injection-molded, All manufactured parts can be finished in many ways using a variety of techniques. The applicable finish will depend on the end-use of the part, the production technique, and the material used in making the part. At First Part, the following finishing options are available to transform and beautify your part:

What is Surface Finishing?

 

Surface finishing is the umbrella term for the many processes used to modify the surface appearance and texture of a manufactured product, and convey the desired feel and look to the part. Generally, a part may be finished to improve appearance introduce customization, and convey specific characteristics (functionality)

 

The most common surface finishes are used to improve abrasion-resistance, increase oxide layers, improve hardness, conductivity, adherence, and corrosion-resistance. The texture of a part may also be modified to make it smoother, grittier, or engrave or etch details into its surface.

 

Mechanical

· Tumbling

The tumbling process is used to smoothen and polish rough surfaces. In this process, the target unit would be tumbled with plastic pellets or oilstones. Here, the sharp edges, machine and tool marks are removed and the defects in small sized components are eliminated to leave a smooth surface.

· Anodizing 

Anodizing is primarily used to increase the thickness of the natural oxide layer on your part's surface. It is prevalent for electronic products made from magnesium, aluminum, and titanium parts. It can be used for decorative, anti-corrosion, heat dissipation, or surface hardness treatments. Anodizing is also very ideal as a priming and painting surface treatment. At First Part, we offer Type 1, 2, and 3 anodizing. We also have chemical film anodizing options.

· Hard Coat Anodizing

This process is similar to the anodizing. Hard coat anodizing uses a thicker anodizing thickness to enhance the properties of wear resistance, corrosion resistance and electrical insulation performance of your project.

· Passivation 

Our passivation process is one of the best available in the industry. We use high quality passivation methods to add a light coat of protective material, such as a metal oxide, to provide a shell against corrosion on your project.

Plating

 

· E-Coat/ ED-Electrophoresis Deposition

E-coating is a specialized system of painting that utilizes electric current to deposit the desired paint and coating on the project. The aim here is to generate a uniform and smooth coating, thereby increasing the hardness and impact resistance.

· Shot Blasting

Our shot blasting technique is used to blast to blast concrete surfaces with steel shots (small steel balls) at high velocities. This process is aimed at removing the contaminants and laitance (soft concrete) to reveal a mechanical profile that promotes improved bonding.

Conversion Coat

· Brushing

Our brushing technique is used for metals that have a unidirectional (one-direction) satin finish. The process is carried out with the aid of a 120-180-grit paper or a belt for grinding. The process can also be used as a method for decoration.

· Grinding/Lapping

Grinding, also referred to as Lapping is a method of utilizing a grinding wheel as the cutting tool for the process of precision machining.

· Alodine

The "Alodine" is an international brand name used to describe the Henkel Adhesive Technologies conversion, anodizing and functional coatings that are applicable for use on Aluminium, Magnesium and a host of other non-ferrous alloys. Alodine coatings are excellent for providing improved protection against corrosion and easing paint adhesion on light metals and their alloys. The film can also be conductive.

Painting

 

· Painting

Manufactured parts may be masked and spray-painted to any color with top-grade automotive paints after sanding and polishing have been carried out to smoothen their surfaces. Painting is one of the best ways to beautify a part and is very flexible for creating different textures. From satin to matte, semi-gloss, gloss, textured, or custom mixes, we can help you deliver or replicate any color and finish in a range of tint, shade, or hues. All painting operations are carried out in our dust-free, weather-controlled bake and spray rooms.

· Powder Coating 

Powder coating involves the application of dry powder to the project by electrostatic adsorption. The coating then settles and becomes perfected on drying.

· Silk screen  

Silk printing is a printing technique applied by utilizing a mesh to transfer ink onto the substrate. This type of printing is popularly applied for patterning or logo printing.

· Silk screen  

Silk printing is a printing technique applied by utilizing a mesh to transfer ink onto the substrate. This type of printing is popularly applied for patterning or logo printing.

· Pad Printing

Our Pad printing technique is a special printing used for on otherwise difficult products and projects across many industries. The procedure involves the transfer of an image from the pattern from a silicone pad onto a substrate with the aid of an indirect offset printing process. Pad printing can be applied to medical and automotive industries, serving promotional, apparels, electronic objects, appliances, toys and sport equipment.

Others

 

· Etching
