We perform high-density laser perforation on sheets, films, or plates to make tiny holes that increase the material’s breathability, wear time, and moisture vapor transmission rate. The advantage of laser perforation is that it maintains the integrity and strength of the material while leaving no working residue behind. It is used in various medical applications, including advanced wound care products, wearable biosensors, advanced diagnostics, and drug delivery devices.
Dedicated engineers and equipment to help you quickly prototype innovative medical devices.
Advanced manufacturing technologies, purpose-built equipment, and vertically integrated capabilities.
Technology to collect critical data and power implantable medical devices.
Focused solutions for medtech and life sciences.
Laser Perforation
Laser Perforation Process
High-density laser perforation involves using the energy from a laser to make tiny holes in sheets, films, or plates. The process begins with a laser that generates a pulse at a fixed repetition rate. Then a beamsplitter is used to convert the single laser beam into a controlled array of high-intensity beams that perforate the material with holes up to 5 microns in diameter. A rotating web carries the material set for perforation to specified locations for each laser pulse. As a result, high-density laser perforation offers precision cutting, high throughput, and accurate positioning. Unlike mechanically powered perforation techniques, no working residue is left on the material.
