Custom Acrylic (PMMA) CNC Machining Services

Custom machined acrylic parts with optical clarity. From rapid prototyping to low-production runs.

Why Choose Acrylic for Your CNC Projects?

Acrylic, also known as PMMA (Polymethyl Methacrylate), is a transparent, high-gloss engineering plastic, commonly known as “organic glass”. It has excellent transparency (transmittance up to 92%), good machinability, impact resistance and weather resistance, and is widely used in CNC machining.

Acrylic CNC machined parts are widely used in various industries, focusing on scenarios requiring transparency, aesthetic appearance and precision, mainly including the display industry (display shelves, display cases, display panels, nameplates, acrylic display frames), electronic & electrical industry (acrylic shells, sensor covers, instrument panels, light covers, insulating parts), decorative & architectural industry (decorative panels, acrylic artworks, window decorations, light guide plates), medical & laboratory industry (medical instrument covers, laboratory test tubes, transparent operation panels (non-toxic grade)) and other fields (toy components, auto interior decorative parts, acrylic molds, customized craft parts).

As-Machined Optical Clarity

We utilize 5-axis CNC machining centers equipped with specialized monocrystalline diamond tools to process acrylic (PMMA) components. This manufacturing method cuts the material with minimal surface roughness, achieving high optical transparency directly from the machine.

Why No Post-Processing?

Our direct-machining process eliminates the need for secondary flame or vapor polishing, which are known to compromise part integrity. By avoiding these thermal and chemical processes, we prevent:

  • Dimensional Deviation: Altered tolerances and rounded edges.
  • Internal Stress: Increased risk of crazing or cracking.
  • Material Degradation: Surface yellowing and reduced optical clarity over the component’s lifecycle due to thermal oxidation.

Instead, our approach maintains the original geometric accuracy and optical properties, achieving 92% light transmission directly from the machine.

FAQs About CNC Machining Services

Standard lead times are typically 10–15 business days. Expedited services (Rapid Prototyping) can be completed in as little as 3–5 business days, depending on part complexity and material availability.

In most cases, we source materials from our approved suppliers to ensure quality control. However, we can machine customer-supplied materials for specialized alloys or specific requirements upon engineering review.

Unless otherwise specified, our general tolerance standard is ISO 2768-m (±0.125 mm) for metals and ±0.25 mm for plastics. Precision tolerances ±0.005 mm are achievable but must be explicitly stated in 2D technical drawings.

Our facility can accommodate parts up to 4000 x 1500 x 600 mm for milling and Ø200 mm x 500 mm for turning.

Yes. We can install inserts (e.g., Helicoils, PEM fasteners) and perform basic mechanical assembly of machined components prior to shipment.

To provide an accurate quote, we require a 3D CAD file (STEP, IGES, or X_T format). If the part has threaded holes, tight tolerances, or specific surface finish requirements, a 2D PDF drawing must also be provided.

We take IP protection seriously. All files are stored securely, and we are willing to sign a Non-Disclosure Agreement (NDA) prior to receiving your data.

Yes. We can provide material certificates (COA) and dimensional inspection reports upon request. Please specify this requirement when placing your order.

We ship globally using major carriers (DHL, FedEx, UPS). Shipping terms are typically Ex Works (EXW) or DAP, depending on the agreement.
