  • CASE STUDIES - Cast Urethane Prototypes & Products
    From portable toilet nozzles to MRI tables, cast urethanes are ideal for marketing samples, test prototypes, or other situations where 1-100 pieces are required, but time and money do not allow a prototype injection-molded tool to be produced. Cast Urethane | Case Study | Quickparts.com

    , not thermoplastics, the number of its applications is not limited. In fact, the wide variety of highly engineered urethanes that are on the market offer a vast array of mechanical, thermal, and electrical properties that can match those of injection molded plastics. In some cases, urethanes offer

  • White Paper: Mold Releasing Process and Silicone
    With the increasing use of cast and injection molded wheels, questions of how these molded wheels are released from their molds and whether or not silicone is used in the process often arise. To answer this, it must first be understood that the release process for casting and injection molding
