Custom Acrylic Parts – Precision CNC Machining for Transparent and Durable Plastic Components
When clarity, strength, and dimensional accuracy are essential, custom acrylic parts offer a reliable solution across a wide range of industries. At our CNC machining facility, we manufacture custom CNC parts from acrylic (PMMA) using advanced routing and milling technologies. From prototypes to production quantities, we ensure your acrylic components meet your specifications with consistency and precision.
Acrylic, also known as polymethyl methacrylate (PMMA), is a transparent thermoplastic often used as a lightweight or shatter-resistant alternative to glass. Its optical clarity, weather resistance, and ease of machining make it ideal for both functional and decorative applications.
Applications of Custom Acrylic CNC Parts
Machined acrylic parts are used in diverse industries due to their clean appearance, durability, and adaptability. Here are some common application scenarios:
-
Retail & Display: Product stands, shelf dividers, custom signage, and brochure holders
-
Electronics & Enclosures: Transparent control panels, light diffusers, device housings
-
Medical & Laboratory: Protective barriers, test tube racks, fluidic manifolds
-
Architecture & Interior Design: Decorative panels, edge-lit signage, lighting fixtures
-
Prototyping & Engineering: Clear component models for design validation or user testing
-
Automotive & Marine: Gauge covers, dashboard overlays, and trim parts
Acrylic is available in clear, tinted, and colored options, which makes it versatile for visual branding or optical use cases.
Choosing the Right Machining Process for Acrylic
The correct manufacturing method for custom CNC parts made of acrylic depends on factors such as part size, tolerance requirements, and complexity. Our team evaluates each design to recommend the optimal process:
-
CNC Milling: Ideal for flat or contoured parts with multiple features. Milling allows for tight tolerances and smooth finishes.
-
CNC Routing: Suitable for larger or thinner sheet-based parts with 2D geometry, such as signs or panels.
-
Laser Cutting (for hybrid orders): Offers fast processing of detailed cuts but is used primarily for non-CNC-specific shapes.
-
Polishing & Edge Finishing: Flame polishing or buffing is available for enhanced optical clarity on edges and surfaces.
-
Drilling & Tapping: For acrylic assemblies, clean and precise holes can be machined and threaded without cracking.
Tolerances for machined acrylic parts typically range from ±0.1 mm to ±0.05 mm, depending on geometry and thickness.
CNC Machining Acrylic vs. Other Plastics
While other plastics like polycarbonate or ABS are often used in industrial applications, acrylic excels in optical and aesthetic-focused designs. It has better clarity than polycarbonate and polishes to a higher gloss, making it the material of choice for see-through panels and displays. However, it is more brittle, which is why machining strategy—including tool selection, feed rates, and fixturing—is crucial.
Our CNC systems are equipped with sharp, high-speed tooling specifically optimized for thermoplastics. This ensures clean edges, minimized burring, and reduced internal stress during machining.
