Machining and molding acrylic requires strict thermal control and specialized tooling to avoid stress cracking, heat discoloration, and surface hazing.
Stress-Relief Annealing Cycles
PMMA easily develops internal stresses during CNC milling, cold-cutting, or laser beam thermal inputs. We perform programmed oven annealing cycles pre- and post-machining to prevent crazing when parts contact cleaning solvents or alcohol.
Diamond & Vapor Polishing
Standard cutting leaves cloudy tool marks. We deploy single-crystal diamond fly-cutting for planar optical windows, combined with solvent-vapor polishing for deep internal chambers, microfluidic channels, and complex manifold ports.
Cast vs. Extruded Material Selection
We guide engineers on raw material grades: Cast PMMA offers superior thermal stability, machinability, and craze resistance, while Extruded PMMA provides tighter thickness uniformities for cost-effective sheet fabrication.
