CNC Milling for Plastic Parts, Panels, and Precision Assemblies
Architectural Plastics provides CNC milling for plastic components where dimensional accuracy, edge quality, and repeatability matter. We machine acrylic and engineered plastics for parts, panels, fixtures, and assemblies—supporting everything from one-off prototypes to repeat production runs. Our focus is not just cutting parts, but producing components that assemble cleanly, finish correctly, and hold tolerance over time.
We run both 3-axis and 5-axis CNC machining depending on geometry, tolerance sensitivity, and downstream fabrication requirements. Typical work includes hole patterns, pockets, profiles, complex cutouts, and alignment-critical features that must fit without field modification. Email drawings, CAD, or a sketch with key dimensions and we’ll respond quickly with feasibility feedback, material guidance, and a clear path to quote.

CNC Milling Machines
We use 3-axis and 5-axis CNC machining depending on part geometry, tolerance sensitivity, and downstream fabrication requirements. The goal is consistent fit, clean edges, and repeatable results from prototype through production.
3-axis CNC milling with a 5′ × 12′ bed, built for flat panels, parts, and repeat production runs.
3-axis CNC milling in process, holding consistent tolerances and edge quality.
5-axis CNC milling with a 7′ × 12′ bed for complex geometry and multi-surface machining.
5-axis CNC milling at an angle, enabling complex profiles and features not possible on 3-axis machines.

Material Availability and Large-Format Sheet Capacity
We maintain a large in-stock inventory of acrylic sheet to support fast CNC turnaround and reduce delays tied to material sourcing. Our material handling and storage infrastructure allows us to machine standard sheet sizes as well as oversized acrylic sheets up to 88″ × 150″, supporting large panels and single-piece components that would otherwise require seams or secondary assembly.
This capacity is especially valuable for architectural panels, display components, and projects where visual continuity or dimensional stability matter.
3-Axis vs 5-Axis CNC Milling
We select 3-axis or 5-axis CNC machining based on part geometry, tolerance sensitivity, and downstream fabrication requirements. Using the correct machine reduces setups, improves feature alignment, and delivers more predictable results from prototype through production.
Automated Tool Changes and Multi-Operation CNC Programs
Our CNC programs are built to run multiple operations in a single setup. Automated tool changes allow us to switch between cutting tools, drill bits, and even saw blades without stopping the machine or re-fixturing parts. This reduces handling, improves feature alignment, and supports tighter overall consistency—especially on complex parts and repeat production runs.
The result is fewer setups, cleaner transitions between operations, and better control over tolerance-sensitive features.
Edge Quality and Finishing Strategy
Machining is only half the result. Edge quality depends on geometry, tooling, feeds, and how the part will be seen and handled in real use. We plan edge expectations early so parts aren’t over-specified or under-finished.
When polished edges are required, finishing requirements are built into the machining strategy from the start.
What We CNC Mill
We CNC mill plastic parts, panels, and assemblies where dimensional accuracy, edge quality, and repeatability matter. This includes hole patterns, pockets, profiles, recesses, and alignment-critical features that must assemble cleanly.
Typical cnc milling outputs:
profiles and perimeters for parts and panels
hole patterns, countersinks, and counterbores
pockets, steps, recesses, vents and openings
repeat runs with consistent reorders
Quality Control and Repeatability
Repeatability is built into the process. We control fixturing, program consistency, and inspection so reorders match the original and assemblies fit as intended.
This approach minimizes variation, rework, and surprises during downstream assembly or installation.
Materials We CNC Mill
We CNC mill a wide range of plastics based on performance requirements such as clarity, impact resistance, wear, chemical exposure, temperature, and finish expectations. If you’re unsure on material selection, we’ll recommend an option based on the application and machining requirements.

FAQS
Do you do prototypes and production runs?
Yes. We support one-off prototypes, short runs, and repeat production work.
What file formats do you accept?
Send what you have. PDF drawings are fine. CAD is welcome.
Can you hold tight tolerances in plastic?
Yes, up to +/- 0.005” or within material-appropriate limits. We confirm tolerance sensitivity during quoting.
Can you machine clear acrylic without chipping?
Yes. Tooling and process selection are matched to geometry and edge expectations.
Do you provide complete fabrication builds too?
Yes. If CNC milling is one step in a larger assembly, we can fabricate and deliver complete components and assemblies.
