Company History

MMD Summerfield Ltd, formerly Summerfield Engineering Ltd was formed in 1967 by three brothers Roger, Mike and Jerry Summerfield. They started out in a small workshop and over the years kept expanding, moving into a purpose built factory in 1976. This has since been extended three times to incorporate larger machinery and an expanded workforce. Heavy investment in modern CNC machinery has helped move the company to a higher level of quality and service.

Over the last 30 years Rogers’s three sons Glenn, Scott and Ashley have been working in the business gaining valuable experience. In 2004 they bought out the company from the founders.

In 2023 the company was acquired by global mining equipment designer and manufacturer, Mining Machinery Developments (MMD). To mark the purchase and align with the MMD brand Summerfield Engineering Ltd underwent a name change to ‘MMD Summerfield Ltd’.

Moving forward as part of a successful global group will not only strengthen MMD Summerfield’s business and secure its long-term future for all its customers and employees, but will also fortify the MMD group’s expertise and experience developed by Summerfield Engineering in over 40 years of manufacturing high quality critical components for MMD. This stamps an exciting new chapter for both companies, securing our prospects for sustained success.
