Frequently Asked Questions

What are the main advantages of acrylic over glass?

Acrylic offers 92% light transmission comparable to glass while being 50% lighter and 10 times more impact-resistant. It’s easier to mold into complex shapes, shatter-resistant, and has better UV resistance than standard glass, making it ideal for automotive, lighting, and display applications.

Does acrylic require special drying before molding?

Yes, acrylic (PMMA) is hygroscopic and must be dried at 80-90°C for 3-4 hours to reduce moisture below 0.02%. Proper drying prevents bubbles, splay marks, and optical defects. We use dedicated dehumidifying dryers to ensure optimal material condition.

What tolerances can be achieved with acrylic molding?

We achieve tolerances of ±0.02mm to ±0.1mm for acrylic parts depending on size and geometry. Acrylic has low shrinkage (0.4-0.7%) and good dimensional stability. Proper mold design, temperature control, and gradual cooling minimize stress and warping.

Can acrylic parts be colored or transparent?

Yes, acrylic can be produced in crystal clear, transparent colors, translucent, or opaque finishes. It accepts pigments excellently while maintaining optical properties. We offer custom color matching services and can achieve vibrant, light-diffusing, or privacy-enhancing effects.

How does acrylic perform in outdoor applications?

Acrylic has excellent outdoor weatherability with UV stabilizers preventing yellowing and maintaining clarity for years. It resists environmental degradation better than most plastics. For outdoor lighting, signage, and architectural applications, UV-stabilized grades ensure long-term performance.

Can you produce scratch-resistant acrylic parts?

Yes, we can use scratch-resistant (SR) grade acrylic or apply hard coating post-processing for enhanced surface durability. While standard acrylic is more scratch-prone than glass, SR grades significantly improve abrasion resistance for high-touch applications like displays and protective screens.
