Automated Stent Crimping Workcell

Machine Solutions is the world leader in stent crimping automation. Our “workcell” technology combines 10 individual process stations into a single integrated machine to increase production rates and reduce labor cost. The system features industry leading stent positioning capabilities so stents are accurately aligned between marker bands. The system can be configured with standard or film integrated stent crimping heads to protect drug coatings from damage and contamination.


  • Single operator can run multiple production processes
  • Parallel processes run simultaneously to optimize takt time and production output
  • Vertical product handling reduces equipment footprint

Stent Crimping Equipment

MSI’s stent crimping equipment has become the industry standard to manufacture most approved stents and scaffolds. All of our stent crimping equipment emphasizes user-control and repeatability, with robust PLC control systems that automate repetitive steps with minimal operator dependency.

By using the best-in-class materials and equipment to produce our machines, our automation platforms increase throughput, improve yields, reduce cycle times and cost. We also offer optimal customer support by providing quality inspection reports and software verification and documentation.

Machine Solutions offers multiple Stent Crimping Machines such as:

  • Drug Coated Stent Crimping
  • Automated Workcell
  • Benchtop Stent Crimping
  • R&D/Pilot Production Stent Crimping

Stent Loading Solutions

MSI’s superior stent loading equipment uses segmental compression technology to reduce the diameter of self-expanding stents. Our robust equipment is used by manufacturing companies all over the world from R&D applications to fully-automated manufacturing equipment. With automated platforms our stent loading equipment provides medical device manufacturers with a more efficient process by increasing throughput, improving yields, reducing cycle times and cost.

Our variety of stent loading equipment includes:

  • Automated stent loading
  • R&D Stent loading
  • Handheld stent crimping tool
  • Disposable heart valve crimping tool

Heart Valve Crimping

MSI’s heart valve crimping tools use proprietary segmental compression technology to reduce the diameter of large stents that have living tissue attached. These tools come in various lengths and diameters and can also be customized to work in various cath labs around the world.

Radial Force Testing

Machine Solutions radial force testing equipment is specifically called out in ASTM standard F3067 – 14 Guide for Radial Loading of Balloon Expandable and Self Expanding Vascular Stents as a preferred apparatus for collection of radial force or hoop force of a stent like device. MSI’s patented compression technology is used to compress cylindrical stents and measure the diameter change and hoop force. This provides characteristics including radial stiffness and strength, chronic outward force during expansion and radial reactive force.

Stent Securement Testing

Machine Solution’s stent testing equipment is proven to produce the most repeatable results compared to tape and shim methods. Our self-aligning system limits operator use so tests results will not be impacted, reducing the number of samples required to get statistically significant results. This equipment can be used for regulatory submissions, competitive product testing, R&D device evaluation and inline manufacturing quality assurance. Our stent testing machines,.give direct feedback on how adjustments to the crimping parameters may impact stent securement results, allowing  R&D engineers to quickly optimize crimper processing settings.
