At Motion Dynamics, we meet every challenge that comes before us head on, and because of it, we’ve developed some of the most unique and innovative products in the industry – products no one else in the world can make or would even consider trying. We don’t stop at producing these high-quality products, either. We back everything we do with what could only be called a customer service obsession. We are proud of our reputation for delivering excellent service on top of expertly designed and manufactured products with tight tolerances and high precision applications for multiple industries.

The following is a list of some of the main products and solutions we deliver:

Micro Wire Components

We craft some of the smallest wire components in the world – including Micro Springs, Medical Coils and Guidewires – working with any cold formable material in sizes down to 0.0005″. The design of wire components in this scale can be very difficult and different than conventional sizes, which is why much of our technology is proprietary and developed by the Motion Dynamics team who specializes in this micro capability. Some of the types of Micro Springs we manufacture include:

  • Compression Springs
  • Torsion Springs
  • Extension Springs
  • Wire Forms
  • Garter Springs

Nitinol Components

Nitinol is the common name used for the shape memory alloy Nickel Titanium (NiTi) and is derived from its place of discovery (Nickel Titanium Naval Ordnance Laboratory). It is uniquely different then typical wire alloys used for cold forming or coiling wire components. A reversible, solid phase transformation (known as martensitic transformation) is the force behind shape memory alloys. The material forms a crystal structure, which is capable of undergoing a change from one form of crystal structure to another. Temperature change typically initiates this transformation in the following way:

  • Above the transformation temperature – Nitinol is super-elastic, able to withstand deformation when a load is applied and return to its original shape when the load is removed.
  • Below the transformation temperature – Nitinol displays the shaped memory effect: when deformed, it will remain in that shape until heated above its transformation temperature, at which time it returns to its original shape.

Nitinol is typically composed of approximately 50 to 55.6% nickel by weight with the balance being titanium. Making small changes in the composition can change the transition temperature of the alloy significantly. These unique properties make Nitinol suitable for many different types of applications, particularly in medical devices.

Spring Products

Manufacturing Micro Springs is one of our specialties. We often assist our customers in developing their micro spring designs, however, ultimately we build products to their drawings and specifications. We operate under a comprehensive quality program (ISO Certified) and support our processes with solid documentation, traceability and service. With every shipment you get the following documentation (unless specified differently):

  • Final Inspection Report – includes critical dimensional data
  • Material Certification – Motion Dynamics’ certification of material size and tolerance, chemical properties and tensile strength.

Wire Forms

A wire form is a general term used for almost any shape of wire component other than the conventional compression, torsion or extension springs. These forms are designed for custom applications and typically perform some spring function. Motion Dynamics Corporation has designed and built custom machinery dedicated to manufacturing tight tolerance, high precision wire forms at a fast and efficient rate. From the simplest to the most complex geometries, we have the equipment to provide you with either a prototype or millions of pieces, and the expert team to assist you with…

  • Wire forms from any alloy including Nitinol
  • Wire forms from any shaped material
  • Straightening and cutting wires to any length
  • Wire sizes from 0.001″ to 0.070″ depending on shape and material type


Wire windings are wire components manufactured by winding the wire around a mandrel or arbor to produce the final product. This process offers some advantages over deflection coiling by driving the wire into tooling that deflects the wire into the desired coil diameters. Winding can provide tighter OD/ID tolerances while deflection coiling offers greater variation in design. Types of windings we provide include:

  • Closed
  • NiTi Coils
  • Ends Ground & Not Ground

Motion Dynamics also recognizes that lead time and design options are critical factors during product development. To accommodate this, we have set up the Rapid Catheter/Endoscopic Coil program that is designed to meet your development needs in the shortest possible time frame. You can take advantage of this service by simply filling out an online form and submitting your request via our contact us link. We will review your request and provide pricing and lead time, doing our best to meet your requested delivery date. You can also reach us by calling 231-865-7400 for direct service.

Expertise and Attention to Detail = Peace of Mind

Motion Dynamics Corporation is ISO certified, ITAR registered, and devoted to delivering high-quality products and the highest level of customer service you can find.
