For anyone outside of the presswork industry and looking into the world of metal pressings, presswork terminology can sometimes be confusing. That’s why we have included a Glossary of commonly used presswork terms on our website – which will explain exactly what is meant by terms such as pressing, stamping, deep drawing. If you require any further explanation, please contact a member of our team.
