Manufacturing medical devices successfully require a deep understanding of the welding process and a stable laser source. But most importantly, it is important to have an integrated solution that includes the laser, motion, vision, tooling, and software. We recommend that you only purchase all of these resources from one vendor.
Designers of medical products continue to develop smaller and more advanced devices. Laser welding medical devices laser welding presents new challenges for both the manufacturer as well as the supplier.
Many professionals offers medicine device laser welding services if you need to, have a peek at this website.
These devices can be as small and delicate as 35 microns in size. For example, guidewire assemblies and catheters are usually made from Nitinol or304 stainless wire, with an outside diameter between 50.8 and 127 microns.
Some flat ribbon wires used in emerging medical applications can be as thin as 25.4 microns. Wire coils with IDs of 127 microns or less are also common in new products. These products can have different dimensions along their lengths, which could be as high as two meters.
In addition to these microdot applications, there are classic applications for welding, such as hermetic sealing implant devices – applications that focus more on automation and reducing cycle times.
