This video was captured at the MD&M Show. It features MicroCare VP Jay Tourigny explaining two important processes: (a) reducing friction between the components in medical devices, and (b) speeding assembly time of medical devices that use silicone tubing or polyurethane tubing. A good introductory video to these two product groups and the benefits they Read More
Silicone elastomers are widely used in the medical device industry. The remarkable physical properties of silicone — durable, flexible, low cost, structural versatility, resistance to bacterial growth, low extractables and easy sterilization — make it a desirable choice for medical-grade tubing and components. But mating silicone parts together can be problematic. Silicone lacks rigidity and Read More
After years of research and regulatory reviews involving numerous federal agencies, the U.S. Environmental Protection Agency, has approved the commercialization of a new molecule from Chemours (ex-DuPont) which is optimized for critical cleaning. With this approval, the new material now can be offered for sale in almost every country in the world. The specific molecule Read More
It can be time-consuming to insert silicone tubing over barbed fittings during the assembly of medical devices. This process can be simplified and made easier — in some cases, dramatically — with modern silicone tube swelling chemistry. Jay Tourigny, MicroCare Vice President, explains.
Engineers design minimum and maximum tolerances into almost every component, defining the allowable dimensional variation any component can carry. Stacked tolerances — when the accumulated tolerances restrict free movement — are a risk with multi-part mechanical assemblies caused when all of the components are at the high end of their dimensional limits. Modern cleaning and Read More
A novel new cleaning fluid from MicroCare has extremely low surface tension which may enable it to out-perform other cleaning choices. One of the biggest barriers to cleaning a surface is a chemical phenomenon known as “surface tension.” In liquids, molecules cling to each other with an “intermolecular cohesive force.” This force is balanced because Read More
In a perfect world, every component would be manufactured exactly to spec. But perfection drives costs higher so it makes sense to accommodate small variations — tolerances — as long as they do not compromise the finished assembly. But there is a catch. Tight-fitting parts from accumulated “stacked tolerances” can make assembly difficult and slow Read More
The cleaning experts at MicroCare have just completed a highly detailed study comparing the costs of aqueous cleaning to the costs of vapor degreasing cleaning. This study was managed by Mr. Rob Lee, of MicroCare, and incorporates the latest information from industry sources, customer experiences and equipment makers. The results of the study were surprising. Read More
The need to dilute the concentrated polydimethylsilxane lubricants used on medical devices is a global issue. The current leaders are flammable solvents which work well but incur substantial risks. A new, nonflammable choice can improve coating quality and eliminate a serious flammability problem for most medical device makers.
