Design For Manufacturability: Rubber and Cast Polyurethane Raw Material Selection

Posted on December 14, 2015 by Nick Cusatis

13-046_362One of the most important items in the design for manufacturability process is selecting the lowest cost rubber or urethane material capable of meeting the application requirements.  Design Engineers are often not elastomer experts, although they have the most direct impact on part cost.  Certainly you could choose a fluoroelastomer for a simple wire grommet application in ambient temperatures with no chemical or fluorocarbon exposure, and it would function.  But why would you spend upwards of $15 per pound on material when you could spend $3 per pound to do the same job?  Molded Dimensions believes in not over specifying the elastomeric material.  Choosing a cost effective rubber or urethane compound not only saves money at project start up, but keeps on giving for the life of the project.  Continue reading


What’s In A Rubber Formula?

Posted on September 11, 2015 by Nick Cusatis

13-046_066Multiple components make up the rubber formula or recipe. The biggest component and determining factor is the base polymer. The base polymer might be Nitrile, Neoprene, EPDM or Natural Rubber for example. This determines many of the formula’s physical properties and is also the biggest cost driver within the formula.
