Ce·DUR Shakes are produced with a manufacturing process known as Reaction Injection Molding (RIM).

       Molding because the process is, in fact, molding-not hot rolling, not extruding and not the more widely used high-pressure plastic injection process. Molding permits the Ce·DUR Shake to exactly replicate the wood shake look and texture/finish including the tapered shape that provides many of the product's unique protective features and after installation appearance.

       Reaction because it involves a chemical reaction of several chemical raw materials mixed together in the mixhead at high pressure and then injected into the mold.
 

       The RIM process is not a new idea. It has been used for over forty years to produce other urethane foam products primarily in the auto and seat cushion industries. Highest volume usage is for the energy absorbing interior components (head and armrests, headliners, and dashboards) in automobiles and trucks. Recent innovations are now permitting the molding of large products such as complex shaped one-piece molded pickup truck bed liners. It is a proven high volume, cost effective, highly automatable process requiring relatively small manufacturing floor space per output unit.

       RIM manufacturing is a perfect process marriage with ENDUR·ALL's patented urethane based material formulation (DURATHON) for producing the tough, durable, high quality rigid foam Ce·DUR Shake.
