THIEME Corporation, St. Charles, IL. www.thieme-us.com. Basic Reaction Injection Molding Operation showing rigid light density foam encapsulation of metal inserts for an automotive application (EA knee bolster). Use of robot technology and several endforms are used. The video shows the basic premise of RIM polyurethane foam molding. We specialize in large format RIM molding and have capabiliy to make single shot parts up to 75 lbs in a single shot (or 6' x 6' x 2'). With our higher density foam systems, such as Prism, Bayflex or Baydur products, this is an excellent process for medical device enclosures, analytical housings and structural parts needing low annual volume production (200-20,000 parts per year). This video shows an automotive part that is mid to high volume in annual use (1000-1,000,000 parts per year).

Reaction Injection Molding (RIM) is using the polyol and isocyante raw materials and "injecting" them into a mold cavity. This starts an isothermic reaction causing the materials to "foam" and fill the mold cavity when the tool is closed. In this case the process begins with the tool open (for an open pour application).
Give me a call if you would like to learn more about Reaction Injection Molding using Polyurethane materials either in a closed or an open injection application.

Why dont you cut out the music and tell us the process stage by stage. I worked on injection moulding machines 40 yrs ago but know very little about this process.

We are working a new video that will do just that for you. Please watch for our forthcoming video this spring.

Yes we currently mold about 6,000 bumpers a year out of this technology and material. Call me to learn more about this at: Thieme Corporation, St. Charles, IL 248-628-2930. Mike Young
You can also see larger parts being made on my other video call "Reaction Injection Molding (RIM) and Polyurethane (PUR) "
