Elm Industries is a leading expert in Custom Thermoset Plastic Molding using compression, transfer and extrusion tools. Thermosetting is a process in which plastic becomes irreversibly hardened upon being cured. Curing is caused by the action of heat and high pressure, which results in extensive cross-linking between polymer chains to give an infusible and insoluble polymer network. A cured thermosetting polymer is called a thermoset.
Elm Industries utilizes unique thermoset materials from suppliers that manufacture exclusively in the USA. Elm specializes in the molding and extrusion of: Glass and fiber-filled phenolics, Diallyl Phthalates (DAP), Urea, Epoxy, and Bulk Molding Compounds (BMC). Temperature, application environment, and the material itself all factor into the construction of molds for these materials. Insert molding is a specialty at Elm Industries.
Parts molded for the military, aerospace, and electronics sectors, and other demanding applications leaves no margin for error; every part must meet exact specifications. Fabricating and running molds that are crucial to today’s industries, Elm knows the importance of product assurance and guarantees the quality of every part that leaves our shop floor.
