Model RC Crimper

Models RCC, RCD, RCJ

The Blockwise type RC radial compression stations are simple, low-cost crimpers with no electronics, suitable for a wide variety of applications in medical device manufacturing, R&D labs, and catheter labs. Designed with low-cost fabrication as the primary goal, these are a bit less accurate and less powerful than the more expensive Blockwise mechanisms.
  • Low Cost
  • Variety of Actuation Types
  • Simple, no Electronics


All type RC compression stations have 10 dies made from POM acetal copolymer. The design is type of Zero-G™ mechanism, with essentially zero die-to-die gap. RC compressions stations are commonly used to “size” balloon-expandable stents – to permanently reduce a stent’s diameter, for example to make it fit snugly over a balloon. These machines are not strong enough to do the high-force part of a stent crimping process – i.e. to attach stents to balloons.
