Epoxies Win Favor in Short-run Tooling
Cambridge, Mass.—Aircraft and missile makers, facing high tooling costs and short production runs, are slashing fabrication costs 70% and more through use of plastic tooling. Favored tooling resins, according to a study carried out at the Harvard University Graduate School of Business Administration, are the epoxies, a versatile group of plastics that are also proving their merit to the aviation industry in structural laminates, adhesives, coatings and encapsulating agents.
