acrylic sheet can be drilled, but speed, support, tool geometry, and hole position must be controlled. Excessive pressure or heat may cause chipping, melting, stress whitening, or cracks, especially near an edge.
Keep the protective film on and support the sheet on a clean backing board. Mark the hole, clamp the workpiece, and use a bit prepared for plastics. Drill with light pressure, clear chips regularly, and reduce pressure near the exit surface. For large or repeated holes, a step drill, plastic hole saw, or CNC milling usually provides better consistency.
A standard metal bit may grab the sheet and create radial cracks. Hole diameter, edge distance, countersinking, and fastener clearance should therefore be defined before machining.
ISO 7823-1 covers general-purpose cast PMMA sheets from 1.5 to 25 mm. ISO 7823-2 covers extruded PMMA sheets from 1.5 to 20 mm. Cast and extruded sheets may machine differently, so the material type should be confirmed during project review.
A manufacturer controls resin selection, extrusion, masking, drilling, CNC machining, polishing, inspection, and packing. A trader normally relies on separate workshops, making tolerance control and corrective action less direct.
With more than 10 years of experience in acrylic, polycarbonate, and polystyrene sheets, we support OEM and ODM projects from drawing review and sample approval to production and shipment inspection. Our automated lines provide monthly processing capacity of about 600 tons.
Confirm material grade, thickness, hole diameter, tolerance, hole spacing, edge distance, finish, protective film, packaging, and order volume. Quality checks should cover position, burrs, cracks, stress whitening, dimensions, appearance, and carton protection. Export projects may also require ISO 9001 controls, RoHS or REACH documents, traceability, labels, and pallet protection.
