High-Quality Custom PMMA (Acrylic) Machining Services
In medical diagnostics, semiconductor equipment, optical instruments, and high-end display systems, Acrylic (PMMA / Plexiglass) is the preferred material to replace glass and other transparent plastics, thanks to its exceptional light transmittance (over 92%), high weather resistance, and good mechanical machinability.
However, acrylic is hard, brittle, and thermally sensitive. During CNC milling, turning, and drilling, it is highly susceptible to edge chipping, micro-cracks, severe tool marks, or localized melting, which compromises both aesthetic appearance and optical clarity.
We specialize in high-precision custom acrylic machining. By utilizing dedicated plastic cutting tools, strictly controlling processing temperatures, and offering multiple polishing techniques, we deliver crystal-clear, chip-free precision parts.

Our Manufacturing & Process Advantages
-
Precision CNC Machining: We utilize high-speed spindles with dedicated high-rake, high-gloss cutting tools for smooth chip evacuation, preventing edge chipping and surface melting.
-
Stress Relief (Annealing): Raw sheets and rods are thermal-annealed before and after machining to eliminate internal stresses, preventing craze cracks (crazing) during use or chemical contact.
-
Multiple Post-Polishing Options:
-
Flame Polishing: Ideal for quick, high-gloss restoration on complex contours and external edges.
-
Diamond Polishing: Delivers mirror-grade optical clarity for straight edges and large flat surfaces.
-
Buffing / Hand Polishing: Suitable for complex 3D surfaces and intricate internal details.
-
-
Strict Tolerance Control: Standard tolerances are maintained within $\pm 0.05 \text{ mm}$, ensuring precise assembly and sealing for fluidic and structural components.
Service Process
