Technical FAQ

Questions Engineers Ask Us

Straight answers to the technical questions that matter in your design and sourcing process.

Can PMMA windows be used with capacitive touchscreens?

Yes. PMMA has a dielectric constant of approximately 3.0-3.5, which is compatible with most projected capacitive (PCAP) touch controllers. For optimal touch sensitivity, we recommend keeping the cover glass thickness under 3mm and can provide custom dielectric testing reports. We also offer ITO-coated PMMA for resistive touch applications.

What is the minimum order quantity for custom PMMA windows?

Prototyping starts at 5-10 pieces with no tooling fee for standard cuts. Production MOQ is typically 50-100 pieces depending on complexity and surface treatment. We support scaling from NPI through mass production with consistent pricing tiers documented in your quote.

How does PMMA compare to Gorilla Glass for display cover applications?

PMMA offers comparable light transmission (≥92% vs ~91% for Gorilla Glass) at 50% lower weight and significantly lower cost. Gorilla Glass has superior scratch hardness (6H Mohs vs 2-3H for PMMA) and better chemical resistance. We recommend PMMA for cost-sensitive, lower-abrasion environments and can supply both materials -- we'll help you select the right one based on your application requirements and budget.

Do you provide AR (anti-reflective) coating on PMMA?

Yes. We apply vacuum-deposited AR coatings (single-layer and multi-layer) achieving reflectance <0.5% per surface. AR-coated PMMA can reach >98% transmission. We also offer combined AR+AF (anti-fingerprint) and AR+HC (hard coat) stacks. Coating durability is tested per MIL-C-675C and ASTM D1044 standards.

Can you handle complex shapes with internal cutouts or countersunk holes?

Absolutely. We use 5-axis CNC routing and precision laser cutting for complex profiles, internal cutouts, slots, and countersunk or through-holes. Minimum internal radius is 0.5mm for CNC; laser cutting achieves tighter radii. All cut edges are polished to prevent stress cracking. Submit your DXF and our engineers will confirm feasibility within 24 hours.
