Finishing Capabilities

CNC milled parts can be left as-machined/as-milled, however, for projects that require more customization, post-processing or surface finishing, Firstmold offers a number of solutions that can change the appearance, surface roughness, chemical resistance and aesthetics of such parts. See some of our finishes below:

· Polishing

High polish with exemplary amount of detail and reflectiveness in the surface of the part. Surface is bright and shiny with a look and feel that is premium.

• Bead Blasting

Bead blasting delivers a satin surface finish or uniform matte finish on parts, removing all tool marks. Bead blasting can also impart textures on your part, and prepare the surface for further finish.

• Anodizing

Anodizing is used to increase corrosion-resistance, scratch-resistance and durability in mechanical parts. It is versatile and can be applied directly to a part, or used after bead blasting, brushing or bright dipping to achieve matte or glossy finishes as required. Firstmold offers Chemical film, type I, type II and type III anodizing sheet metal parts. Anodizing is also an ideal surface treatment for painting and priming.

• Powder coating

Powder coating delivers strong fatigue and wear resistance, and is compatible with virtually every metal material. It can be used as an alternative to anodizing finishes.

• Brushing

Brushing is an aesthetic surface finish used to draw traces and give a brushed feel on the surface of the material, usually metals. It is used on ABS, Aluminum, Stainless Steel and Brass

Other Post-Processing and Finishing Capabilities

Save time, money and logistic efforts by completing your parts final touches with Firstmold. We provide a range of secondary processing options post-molding to decorate, brand and customize your part. Our secondary operations currently include:

· UV coating

· Silk or Pad printing

· Chrome plating

· Laser etching

· Labelling

· Engraving

· Threaded Inserts

· Media blasting

· Assembly

· Painting/Spray painting

Additional Resources & FAQs

1. What is CNC Milling?

CNC milling is a type of CNC machining operation that uses a cutting tool to remove materials from the workpiece by moving the tool around the workpiece till the final design is achieved.

2.What materials can you use with CNC Milling?

CNC machining can machine just about any materials; however, the most common materials include plastic, brass, copper, steel, stainless steel and aluminum.

3.Why should I choose CNC Milling?

CNC machining is capable of making parts with high precision and accuracy. It can also deliver parts with complex geometries that will otherwise be difficult to make through other means. It is fast, and can be used for low-volume manufacturing without incurring heavy tooling cost.

4.How quickly can you produce parts using CNC Milling?

Our standard leadtimes for CNC machining operations is 1-7 days. This leadtime is dependent on the geometric complexity of the design, size, volume and tolerance levels required.

5. How is CNC milling different from CNC turning?

CNC milling is ideal for making smaller parts with complex geometries while CNC turning can process relatively larger parts that have cylindrical orientations. Also, while CNC milling operates by rotating the cutting tool around the part, CNC turning operates by rotating the part along a static tool.
