Medical stent laser cutting machine: the perfect balance of precision and speed
In the field of vascular stent manufacturing, the core of minimally invasive interventional devices, laser cutting machines have become precision cutters for shaping "life channels" with their unparalleled precision and controllable efficiency. Its core performance indicators - cutting accuracy and speed, directly determine the safety and mass production capacity of stents.
The ultimate pursuit of micron-level precision
Ultra-fine spot: Using femtosecond/picosecond ultra-short pulse lasers, combined with precision optical systems, the focus can reach several microns to more than ten microns, comparable to the diameter of a hair.
"Cold processing" advantages: extremely short action time (picosecond/femtosecond level) almost no heat diffusion, the incision is extremely smooth without burrs, slag, and the heat-affected zone is extremely small, perfectly retaining the superelasticity and biocompatibility of materials such as nickel-titanium alloys.
Complex structure control: accurately depict the fine grid units, support rings and connecting ribs on the stent, with a stable accuracy of ±5 microns, to ensure that the mechanical properties of the stent after expansion are uniform and reliable, greatly reducing the risk of fatigue fracture and restenosis.
Intelligent improvement of speed and efficiency
High dynamic response: The high-speed galvanometer system drives the laser beam to move precisely on the surface of the tube at extremely high acceleration, achieving fast scanning and cutting of complex trajectories.
Optimize process parameters: By precisely controlling the laser power, frequency, pulse overlap rate and auxiliary gas, the single-piece cutting efficiency is significantly improved while ensuring the quality of the incision.
Automation and intelligence: Integrate automatic loading and unloading, visual positioning calibration, and online quality monitoring to achieve continuous and stable production, shorten the processing cycle, and improve overall output efficiency.
The medical stent laser cutting machine combines the ultimate micron-level precision with the continuously optimized high-speed processing capability. While ensuring the safety and reliability of each stent, it meets the growing clinical needs and becomes a precision manufacturing engine to promote the development of minimally invasive interventional treatment.
