Plastic Fabrication Services for Precision, Finish Quality, and Repeatability
Architectural Plastics provides custom plastic fabrication for B2B and private clients who need clean aesthetics, tight tolerances, and repeatable results. We support projects from early prototypes through production runs, with in-house machining, forming, bonding, and finishing.
We’re built for real execution. Our 16,000 sq. ft. facility in Petaluma, California is set up for efficient throughput on both one-off builds and scaled production. When your project requires it, we also integrate wood and metal components to deliver complete, installation-ready assemblies.
Architectural Plastics fabricates plastic parts, panels, and assemblies for project teams who can’t afford surprises. We specialize in acrylic (including clear-bonded seams), tight-tolerance CNC machining, thermoforming, and premium finishing—supported by real process control so parts fit, look right, and install cleanly. From one-off prototypes to repeat production, we build around manufacturability and delivery constraints from day one.

How Clients Typically Work With Our Fabrication Team
Most fabrication projects use multiple processes. The sections below explain how each fits into a complete build.
CNC Machining and Cut Components
Best for:
Tight tolerances, repeatability, clean edges, hole patterns, and precision cutouts. We machine plastics for parts, panels, fixtures, and assemblies using repeatable programs and controlled outputs. The goal is consistency—so reorders match the original.
You receive:
CNC-routed parts with stable dimensions and repeatable geometry
Drilling, countersinks/counterbores, and accurate patterns
Finish planning that matches the application (show edges vs functional edges)
Bonding and Seam Construction
Best for:
Clear acrylic enclosures, display components, structural acrylic assemblies, premium visual requirements. Clean seams don’t happen by accident. We plan seam strategy early—so the finished piece looks intentional, performs correctly, and installs without stress.
You receive:
Seam strategy aligned with geometry, viewing angles, and handling
Controlled bonding for clear assemblies where fit and finish matter
Assembly planning that reduces visible stress and “surprise seams”
Finishing and Polishing
Best for:
Premium optics, museum-grade viewing, edges seen under real lighting, high-touch surfaces. Finish is where plastic projects succeed or fail. We build around edge quality, polish level, and durability requirements so parts look right in real-world use.
You receive:
Polished edges and surfaces matched to viewing distance and lighting
Finish consistency across sets and production runs
Clear guidance on what “show finish” means for your part geometry
Thermoforming Plastic Parts
Best for:
Curved geometry, formed covers and shields, repeatable formed parts, large-format plastic components. When geometry demands it, thermoforming produces complex shapes with controlled results. We design and fabricate with forming constraints in mind so the end product stays consistent.
You receive:
Forming approach aligned with geometry, material, and finish targets
Mold/method planning for repeatability
Formed parts that fit without “fight” during installation
Multi-Material Assemblies
Best for:
Complete deliverables that require plastic + wood + metal integration. We build integrated assemblies when the project requires a complete, installation-ready deliverable. Fit-up, finishing transitions, and delivery constraints are managed as part of the build.
You receive:
Coordinated fit and finish across materials
Assembly sequencing that reduces install friction
Packaging and delivery planning for high-value assemblies
Shipping & Logistics
Best for:
Finished parts and assemblies that need to arrive intact, on time, and ready to install.
Fabrication doesn’t end when a part leaves the machine. We plan packaging, handling, and shipping as part of the build—especially for finished, high-value, or oversized components where damage or delays aren’t acceptable. Crating, palletization, and carrier selection are coordinated to match the geometry, finish sensitivity, and delivery conditions of the project.
You receive:
Packaging and crating designed around part geometry and finish sensitivity
Palletized, crated, or dedicated-load shipments as required
Coordination with carriers for LTL, FTL, or white-glove delivery
Clear labeling, documentation, and delivery sequencing when needed

Multi-material assemblies (plastic + wood + metal integration)
Packaging, crating, and shipping coordination
How Projects Run
Start with a sketch, reference photos, CAD, or drawings. We confirm material selection, manufacturability, finish targets, tolerance sensitivity, and any assembly or installation constraints. From there, we move into fabrication with repeatability in mind—so parts fit, finish, and install the way they should.
If the project is high-visibility or high-risk, we’ll recommend prototyping to validate seams, finish level, fit, and handling before committing to full production.
Materials We Work With
We fabricate a wide range of plastics and sheet goods, including acrylic (PMMA), polycarbonate, HDPE, UHMW, PVC, ABS, and related materials. Material selection is driven by clarity, impact resistance, wear, chemical exposure, temperature, and finish requirements. If you have a specific material requirement, we’ll confirm suitability and availability for the application.

FAQs
Do you handle prototypes and production runs?
Yes. We support one-off prototypes, short runs, and repeat production work.
Can you work from a sketch or do you need CAD?
Either works. A clear sketch with dimensions and reference photos is enough to start. CAD files are welcome.
Do you fabricate only plastics?
Plastics and wood are our core. We also build multi-material assemblies that integrate wood and metal when the project requires a complete deliverable.
Can you ship nationwide?
Yes. We build around packaging and handling requirements from the start, especially for finished, high-value components.
What information do you need to quote?
Overall dimensions, quantity, deadline, ship-to city, finish expectations, and any drawings/photos/CAD.
