Drilling & Perforating

A successful CO2 laser drilling and perforating application requires a balance of high peak power and good rise/fall times to ensure fast throughput. When drilling and perforating, coupling the energy into the material efficiently yields clean, accurate holes through the material. The energy balance is especially critical for materials like ceramics. The laser operates in a pulsed mode to remove material steadily, until penetration occurs and a hole forms. Pulses with discreet durations and energy levels create very small, repeatable hole diameters. Synrad offers pulse lasers with the industry's best peak pulse power and exceptional rise and fall times, for precise pulsed laser beams.

Paper & Paperboard

Paper and paperboard converting often involves perforating and/or drilling. Using lasers in this application provides the advantages of faster, easier set-up with no new tooling expenses. Synrad offers a variety of pulse laser options in the 100W to 400W range for high-speed processing with the industry’s best peak pulse power at these power ranges. Further, fast rise/fall times and the high peak power minimizes the heat affected zone avoiding discoloration around the holes. Recommended paper and paperboard drilling and perforating lasers:

Ceramics

High beam quality and peak power is necessary for creating tight, symmetrical holes in ceramics. Scribing ceramics requires a precise series of deep symmetrical holes and pulsed lasers often used for this process deliver highly focused pulsed energy into the ceramic material. Recommended ceramics drilling and scribing lasers:

Metals

To create symmetrical holes that are free of dross with minimal discoloration, a CO2 laser with 200W – 400W with high peak pulse power is required. Oxygen assisted cutting improves cutting speed but results in dull oxidized edges, nitrogen assisted is slower but yields shiny edges free of oxidation. Recommended thin metals drilling lasers:

Rubber & Compounds

Rubber weather stripping found in many automotive and industrial applications is not produced from natural rubber, instead manufactured primarily from polymer compounds. Although cut speeds vary slightly depending on the exact chemical makeup, rubber compounds in general exhibit similar behavior when drilled (trepanning) with CO2 lasers. Rubber’s absorptivity at the CO2 wavelength is high enough that the cutting process is by vaporization—instantaneous absorption of the beam’s energy causes the rubber to simply vaporize into a gas. Recommended rubber and compunds drilling lasers:

Thin Films

Thin films used in many packaging processes require drilling (hole cutting) and perforating to facilitate opening or promote breathability. Synrad lasers excel at high-speed precision drilling and perforating operations. With a wide range of pulse lasers in multiple wavelengths, and exceptional peak pulse power for mid-power (100 Watt – 600 Watt) lasers, Synrad lasers can accurately drill/perforate thin films at high speeds. Recommended thin film drilling and perforating lasers:

Plastics

High-speed drilling/perforating in many plastics yield holes that are smooth and free of rough edges. Synrad lasers with high peak pulse power, fast rise/fall times, and excellent beam quality deliver clean, tight holes. Avoid discoloration or extensive melt lips with a minimal heat affect zone resulting from efficient delivery of pulsed energy to the target material. Recommended plastics drilling lasers:

Wood

Drilling precise holes in wood with a pulse laser ensures exact repeatability and minimizes discoloration on the surface. Some discoloration along the inside edge of the hole(s) will occur. Synrad offers several pulse laser options in the 200W to 400W range for wood through-hole drilling with exceptional peak pulse power at these power ranges. Recommended wood drilling lasers:
