Notre Dame Football Taught Me Important Lessons About Rubber Molding For Medical Devices

It is well known that Notre Dame football has a devoted following and is looked upon to contend for the national championship year in and year out. But how did they get to achieve such lofty status? I like to think it all started on November 1, 1913. That was the day Notre Dame changed football forever. No, it was not the first forward pass (that happened seven years earlier), but an innovation on this basic strategy that would leave an indelible mark on the game. On this day, coach Jesse Harper used his normal power running game, but also deployed a deftly styled passing attack from quarterback Charles “Gus” Dorias to future coaching legend Knute Rockne. The difference? Previously all forward passes had the receiver stop and stand in place to catch the pass. Harper had Rockne catch passes in stride. The Cadets of Army could not adapt to this new tactic and fell to Notre Dame 35 – 13. Soon after all receivers adopted this tactic.

To illustrate this need for constant innovation, we recently worked with a large medical device company to solve a challenge on one of their x-ray machines. They had designed some molded bladders for use in the system, but they were having some trouble. The fit of the rubber bladders was perfect, and they functioned correctly, holding the designated fluids. However, the original nitrile material they used for the prototype molding included carbon black. Carbon black is conductive and was causing sparking in the machine and shorting out x-ray heads. They had tried several other materials on the prototype with another rubber molding team, but were unable to find the solution. To overcome this, our team at Allstates Rubber put our years of knowledge together to develop a proprietary material to remove the carbon black and maintain the properties required to hold the fluid correctly. Innovation carried the day and allowed for a successful custom molded product. The end result was a very happy medical device manufacturer and a new piece of equipment going out into the world to help with diagnosing patients correctly.

Take Advantage of Allstates’ New Rubber Material Selection Guide

One of the most frequently asked questions we receive from a customer is “what’s the best material for this project?” As rubber molding and fabrication experts, we have the experience and knowledge to help you match the right rubber material to meet the final component’s requirements.

rubber-molding-material-guide-thumbWhen selecting the proper material, there are many factors to consider, such as type of elastomer for the application and durometer (hardness).  To help you understand the qualities of the most commonly requested products, we have created a Rubber Molding Material Selection Guide. This guide is designed to give you background information on many of the most commonly used products and their strengths and weaknesses.

The comprehensive guide provides properties of each material such as:

  • Operating temperature range
  • Hardness
  • Abrasion, chemical, sunlight/weather, electrical, tear, and water resistance
  • Tensile strength
  • Metal adhesion

A material overview succinctly describes the material and its uses. The materials advantages and disadvantages are listed.

Setting this guide apart from general material information that can be found in other resources is the addition of “Mike’s Tips.” Mike refers to our own President of Allstates Rubber, Mike Burke, who shares his own experiences and recommendations about each material. The benefit of these tips is in the real-world expertise of someone who has been in the business and understands how rubber materials react. With this information, choosing a material is made a little simpler.

Going beyond basic information is what sets this guide above other references. The valuable information included will help the reader select the correct custom rubber material to meet the requirements or certifications for their application.

Allstate’s Rubber Molding and Material Selection Guide is a free download from our website. If you have a material question or a project you would like to discuss with Mike or any other knowledgeable Allstate professional, please feel free to contact us.
