Fast, clean edges — without the micro-cracks

Laser processing is the fastest route for flat parts: gaskets, windows, spacers, masks and engraved scales. The risk in acrylic is heat-affected edge whitening and delayed stress cracking — we engineer that risk out.

Capability 02 — Laser Cutting & Engraving

Clean edges, no micro-crazing

We control power, speed, assist gas and cut sequencing per material and thickness, then anneal parts where the application demands it. Edge quality is treated as a specification, not an accident.

CO₂ cutting up to 25 mm acrylic with polished, flame-like edge quality straight off the bed.
UV laser marking for fine scales, part IDs and alignment marks without micro-cracks or whitening.
Cut-to-bond accuracy edge straightness within 0.05 mm so laser-cut layers stack cleanly for solvent bonding.
Kerf compensation applied from measured cut data, so nested parts hold drawing dimensions.

Process route

How we run it, step by step

File preparation. Vector geometry checked, kerf compensation applied, common-line nesting planned where it saves material.
Parameter qualification. Power, speed, assist gas and focal position set per material brand, thickness and color.
Cut sequencing. Internal features before outlines, cool-down pauses on thick sections to limit heat build-up.
Cleaning & annealing. Residue removed, parts annealed where bonding or optical use demands low residual stress.
Edge inspection. Edge clarity and straightness checked against the agreed acceptance criteria.

Process envelope

Typical values. Tighter limits are available after a drawing review — share the functional requirement rather than a blanket tolerance.

Max. cutting thickness (PMMA)	25 mm	—	Thicker sections sectioned in steps on request
Edge straightness	0.1 mm	0.05 mm	Critical for solvent-bonded stacks
Typical kerf	0.15 mm	0.1 mm	Compensated in tooling files
Engraving minimum line width	0.2 mm	0.1 mm	UV marking for fine scales and IDs
Min. hole / slot width	0.3 mm	0.15 mm	Material-dependent

Applications

Where this process earns its keep

Gaskets, spacers & insulators Fast, low-cost parts from PMMA, PC, PETG and PTFE sheet.
Optical windows & light guides Flame-polished edges, angle-controlled bevels, engraved alignment marks.
Encoders & scales UV-engraved graduations readable under transmission or reflection.
Cut-to-bond layers Layers cut with straightness held for subsequent solvent or thermal bonding.
