Application of laser cutting machine in medical stent cutting process analysis

Laser cutting is a processing technology that utilizes focused high power density energy. Compared with traditional mechanical knives, laser cutting has the characteristics of high accuracy, fast speed, automatic typesetting and material saving, smooth incision and low processing cost.

The cutting quality of medical stent mainly depends on the cutting dimensional accuracy and cutting surface quality, including incision width, incision surface roughness, heat affected zone width, incision section ripple and slag hanging on the lower surface. There are many factors that affect the cutting quality of support. So, what are the advantages of laser cutting machine in the application of vascular stent microporous structure?

The raw materials used in the first production of the stent are usually medical thin-wall metal pipes, and seamless pipes are used to ensure the consistency and coherence of the material. The metal can be 316LVM medical stainless steel, cobalt-chromium alloy or nickel-titanium shape memory alloy. As a stent for three types of medical devices, while taking into account the uniformity of the chemical composition of the material, it is also necessary to consider its size requirements and shape requirements, such as pipe diameter, wall thickness and various dimensional deviations. For micro-devices such as vascular stents, the smaller the slit width, the better, in order to achieve high power density and fine incision, the focus spot diameter needs to be small. Therefore, femtosecond laser cutting machines are often used for cutting metal vascular stents.

Men-luck super fast femtosecond laser cutting machine has stronger stability, the cutting surface heat affected zone is very small, often used in polymer materials, brittle materials, heat sensitive ceramics and so on. The section is smooth and smooth, reducing carbonized dust particles, and is more suitable for processing products with high requirements. As a professional laser equipment manufacturer, Men-luck mainly has laser cutting machine, laser welding machine, laser marking machine, etc., which is widely used in medical equipment, sheet metal processing, 3C, auto parts machining and hardware and other industries.
