Rapid prototyping at H T Brigham adds value for customers
The benefits of 3D printing have been widely reported; fast, low-cost and kind to the environment. This rapid prototyping allows working concepts to be ruled in or out more quickly, speeding up the development process and reducing the project lead time as a whole.
Celebrating 70 Years of Presswork Success
Birmingham metal pressing manufacturer, H T Brigham celebrates 70 years in business this year. The company was established in 1947 by Hugh Terrence Brigham who, with just £80 start-up capital, operated a single hand-press from a garage shed in Birmingham, delivering components locally using his motorcycle and sidecar. He was paid £9 9s 8d on the completion of his first order.
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.
