What is Machined Acrylic (PMMA)
Machined acrylic, also know as PMMA (polymethyl methacrylate), it is the most common transparent plastic that often used as alternative to glass. Acrylic machining parts are widely used in many applications, especially when you need clarity, good impact strength, and weather resistance.
Types of PMMA Machining We Offer

Key Benefits of Acrylic CNC Machining
- Excellent optical clarity makes it ideal for lenses, covers, and viewing windows.
- Machined Acrylic parts can meet tight tolerances
- PMMA material is stable and rigid, it can holds shape well under light mechanical load.
- Arcylic is resitant to UV and weather makes it suitable for both indoor and outdoor applications.
- Arcylic machining parts are easily to achieve good surface finish and clean edges with proper feeds an tools.
-
Shortcomings of Acrylic CNC Machining
- Arcylic is brittle compared to other plastics, it can get crack or chip during machining.
- It is not suitable for higt-heat environments as it get soften at relatively low temperature.
- If not handled properly, the surface can scratch easily.
- PMMA requires longer machining time to avoid creacking.
