We have a long history of manufacturing plastic knobs, especially phenolic plastic knobs.  But we also mold phenolic custom plastic parts, such as the plastic butterfly valve for the oil & gas industry. We started manufacturing butterfly valves a few years ago because the company that needed them got fed up with their overseas vendor. 

Long lead times, poor communication, and inconsistent quality from their overseas vendor made them decide to source domestically, and Davies Molding got the call to quote. We were able to manufacture a butterfly valve that met their strict quality standards and short lead times.  We chose a compression molding process using a phenolic material that is chemical and water resistant – key attributes for a butterfly valve.  We now manufacture a large range of sizes of butterfly valves along with other custom compression molding.
