CNC Prototyping Cases
Materials for CNC Prototyping
CNC prototyping is essentially using CNC machining to quickly make prototypes. This means any material that can be CNC machined can also be used for CNC prototyping. If you break it down to specific material grades, there are literally hundreds of them to choose from.
ABS
A general-purpose prototyping plastic that CNC machines cleanly for durable consumer-product housings
PC
A tough transparent plastic for CNC machined shatter-resistant prototype lenses or guards
PMMA
An optically clear plastic for CNC polishing into glossy display prototype parts
POM
A dimensionally stable slippery material ideal for CNC prototyping low-friction gears and bearings
PA6
A tough wear-resistant nylon for CNC prototyping durable mechanical sliding components
PA66
A higher-strength nylon variant for CNC machining heat-resistant functional test parts
PA6 GF30
A glass-filled nylon that stays rigid under load for CNC machined structural insulators
PP
A lightweight chemical-resistant plastic for CNC prototyping living hinges and tank linings
HDPE
An impact-resistant easy-flow plastic for rapid CNC cutting of budget-friendly large covers
PTFE
An ultra-low-friction fluoropolymer for CNC prototyping non-stick chemically inert seals
PEEK
A high-temperature engineering thermoplastic for CNC prototyping aerospace and medical load parts
Surface Finishing Options for CNC Machined Prototypes
Experience the convenience of 天美影院's one-stop service with our full range of surface finishing options and competitive pricing
As-Machined (Raw)
La superficie de la pieza pasa de áspera a lisa y refinada. En el caso de materiales transparentes, la claridad aumenta considerablemente tras el pulido.
Granallado
Removes all visible machining marks to give the prototype a smooth, uniform, and non-reflective matte finish with a subtle frosted texture.
Anodizado
Adds a protective layer to aluminum prototypes, resulting in a premium, metallic-tinted appearance in custom colors without hiding the metal’s natural texture.
Recubrimiento en polvo
Covers the raw material entirely with custom Pantone colors, making the prototype look exactly like a colorful, retail-ready mass-produced product in either a glossy or matte finish.
de molde
Smooths the surface completely, giving metal prototypes a highly reflective mirror-like shine, and turning clear plastics (like Acrylic) into a fully transparent, glass-like state.
Galvanoplastia
Coats the prototype with a thin layer of metal (such as chrome or nickel), transforming its exterior into a shiny, ultra-smooth, and highly reflective premium metallic finish.

If you need high precision, a fine surface finish, and parts that are transparent or made of metal, CNC is your best choice.
If your design is complex, still being updated often, and you need to keep costs down, 3D printing is the way to go.
If you only need 10–50 plastic parts, want a rubber-like feel or clear material, and don’t want to pay for a mold, vacuum casting is the best option.
If your design is final and you need thousands of parts for market testing, rapid injection molding is the top choice.

FAQ for CNC Prototyping Services
What should I do if the CNC prototype dimensions are out of tolerance?
We carry out full inspection before shipment. If you find any dimensions exceeding the drawing tolerance after receipt, please provide the inspection report. Once confirmed, we will immediately rework or remake the parts free of charge and cover the related shipping costs.
I'm not familiar with materials. Can you recommend suitable plastics or metals for CNC machining based on my application?
Certainly. Just tell us the intended use of the prototype, such as high temperature resistance, high toughness, transparent display, or food contact, and our engineers will recommend suitable materials (e.g., ABS, PC, POM, aluminum alloy 6061, 7075, etc.).
Will your thin-walled parts deform during CNC machining?
Can you apply spray painting according to Pantone color codes? Will there be a noticeable color difference?
Are there any set-up fees or programming fees for CNC prototype sampling?
After successful prototype testing, can you undertake small-batch CNC production?
How long is the CNC prototype quotation valid?
Our quotation is valid for 30 days. Due to price fluctuations in raw materials such as aluminum alloys and plastics, the price may need to be reconfirmed after expiry. If raw material market prices experience extremely large fluctuations during a certain period, the validity period may be relatively shortened accordingly.
