CNC Machining Plastic

Plastic prototype parts ensure the product design is sound when starting a new injection-molding project. For most plastic parts, a CNC machined prototype will provide exactly what is needed for testing. CNC machining plastic parts allows customers to test the form, fit, and function of injection molded parts without the required expense and time to produce injection mold tooling. CNC machining is also an ideal low-volume manufacturing process for producing up to 100 pieces. Consider CNC machining plastic as a cost-effective route for smaller projects.

ICOMold’s multi-axis, high-speed CNC milling machines can produce complex CNC parts and prototypes quickly. CNC prototype parts can be at your doorstep within a couple of days. There are no size limitations on CNC machined plastic parts. Secondary processing is available for most CNC parts, including painting, assembly, and packaging. ICOMold by Fathom only uses high-quality plastic resins for CNC plastic prototype parts. 


ICOMold by Fathom believes that quality comes first. This is affirmed by our commitment of engineering resources to our Quality Control (QC) Department. Our highly trained QC staff ensures top-notch production by painstakingly reviewing designs and certifying raw materials. We perform dimensional and appearance checks, then document all results in a QC report. ICOMold by Fathom is ISO 9001:2015 Certified.
