Precision Coils

Due to our advanced grinding and welding equipment we offer a one stop shop for making advanced guidewires. Modern Grinding's equipment is tailored to quick product turnover and high repeatability. We can help with a small coil prototype runs or large runs (50,000+) alike.

Medical Quality Coils

Modern Grinding understands the high level quality demands of the FDA and we help make sure our customers adhere to these demands. We work with each large customer to make sure that our process and quality standards meet your needs for getting a coil project from inception to the mass market.

Custom Engineered

Customers come to us because they know we are experts in the field. Either send us a drawing or come to us with an idea for your coil and we can help you through the process of engineering the perfect coil for your application. Some of the options that you have for coils include coil wire size (.002"-.032"), coil size (.010" to .3"), closed end, open ended, continuous wound, dead coils, multi taper, multi-diameter coils and wide variety of other options.

Speaking of custom engineered, our coil winding machines are also custom designed for top of the line performance. We start with common machines from the market but add our own special design to improve quality and throughput.

From Unifilar to Multifilar

Modern Grinding has the capability to coil up to 8 separate wires into a single coil. The majority of the wires that we make are unifilar but don't hesitate to reach out with your next multifilar coil manufacturing project. We can make coils out of stainless steel, nitinol springs, radiopaque materials and a variety of other materials.
