CNC Milling

Architectural Plastics provides CNC milling for plastic parts, panels, and assemblies that require precision, repeatability, and clean finishing. We support projects from one-off prototypes through production runs, and we keep part programs on file for repeat orders.

Our CNC router is built for large-format sheet processing (up to 86” x 144” in size) and includes 5-axis machining capability, a multi-tool changer, drilling, and saw cutting capacity. That combination lets us machine complex geometry, hold tight tolerances reliably, and move fast without sacrificing finish quality.

What We Do on CNC

• CNC routing and profiling for plastic parts and panels

• Drilling, countersinks/counterbores, and hole patterns

• Saw cutting for efficient straight cuts and repeatable panel breakdown (click here to learn more about cut-to-size panels)

• 5-axis machining for angled features, compound geometry, and hard-to-reach details

• CNC edge polishing (flat and beveled) for presentation-grade edges (click here to learn more about our automated edge polishing solutions)

Precision and Repeatability

CNC milling is only valuable if it’s consistent. We build programs for repeatability so parts fit as intended across single parts, short runs, and ongoing reorders. If your project requires tight tolerances, send the critical dimensions and we’ll build the machining plan around them.

Production Runs and Stored Part Programs

When you need the same parts monthly, quarterly, or annually, we keep your part files and programs on record so you can reorder without starting over. This reduces lead time, improves consistency, and avoids revision confusion. Click here to learn more about our product design and project planning assistance.

What to Send for a Quote

To quote CNC milling quickly, send: material, thickness, quantity, deadline, ship-to city, and a drawing or CAD file. If you don’t have CAD, send a dimensioned sketch plus photos or reference links and we’ll advise the fastest path.

FAQs

Do you offer 5-axis machining?

Yes. We use 5-axis machining for angled features, compound geometry, and details that aren’t practical with standard 3-axis routing.

Can you handle prototypes and production runs?

Yes. We support single prototypes, short runs, and high quantity production with consistent part programs.

Do you polish CNC edges?

Yes. We offer CNC edge polishing for both flat and beveled edges when presentation-grade finish is required.

What tolerances can you hold?

Generally, we can hold a +/- 0.005” tolerance which can vary slightly depending on material, thickness, geometry, and part size. If you call out critical dimensions, we’ll confirm a realistic tolerance plan before cutting.

Can you work from my CAD files?
Yes. Send your file format and we’ll confirm compatibility and any needed revisions before machining.
