At Laserage, we can easily accommodate requests for complex components requiring multiple laser fabrication techniques and secondary processes.
The drawing depicted here is a cannula tube that is used as part of anesthetic delivery system for medical applications. The cannula is constructed of a white polycarbonate tube that we mark and drill using laser-based technologies. The laser marking is used for orientation of the tube and the 24 holes are drilled in a spiral pattern for delivery of the anesthesia. After drilling, the tube is cleaned using a deionized surface cleaning process and the end of the tube is melted to form and cap the cannula end according to the customer-provided specifications.
The finished tube measures 0.12” in diameter and is 7.875” long. We are required to hold hole tolerances to as tight as ±0.002” for this precision application. The tubes are 100% inspected using an automated inspection system to verify the relation of the holes with the orientation laser marking. AQL inspections are performed on the offset of the holes at the end of the tube, the hole diameter, and the total number of holes, and additional inspections are regularly performed to verify the rotation of the hole pattern.
Through 35 years of service, we have produced more than one million of these cannula tubes annually for this internationally-based customer—which illustrates that we have exceeded the customers’ expectations every single delivery.
