About us.

The leading sand casting engineering and foundry business globally.


Grainger & Worrall continues to be at the global forefront of castings development and innovation. 

The world is demanding ever-lighter, ever more efficient means of propulsion and we are helping to drive that trend. We are only able to do this because of almost three quarters of a century of accrued know-how. No other castings organisation has the same resource or history of delivery.



Our Values.

Culture is incredibly important in any organisation. These values represent ours.



We are privileged to have world-class customers, organisations that lead the world in their respective spheres – and we continue to deliver innovation in order to help them stay there.

We are very open minded to change – market change, regulation change, fundamental energy change. In many respects, we think we’re unique, underpinned by an underlying ethos of humility and respect, to our clients, our employees and our suppliers. Yet that does not compromise on an insatiable desire to keep delivering ground-breaking innovation to our client-base now, and in the future.

Our history.



The company dates back to 1946 when brothers-in-law Vernon Grainger and Charles Worrall initiated their venture in post-war Britian. Operating in the Midlands, they began as pattern makers and casting manufacturers. Ownership of the company had been held by Vernon Grainger’s three grandsons – Matthew, James, and Edward.

However, a more recent development saw a change in ownership through a management buyout, leading to the creation of an umbrella company known as Evolution Castings Group Limited.

Founded 1946


In post-war Britain Pattern Makers and Brothers in Law Vernon Grainger and Charles Worrall went into partnership establishing their first Master Pattern Shop at the Laurels (Stable Annexe) Clarence Street, Upper Gornal, and by 1951 the company had grown to 6 people.


A business move to Hydes Quarry, Rock Street Upper Gornal, permitted further expansion and in 1974 the workforce numbered 18 supporting the local foundry industry with the manufacture of high quality patterns and tooling.



The company built its own premises in Holloway Street, Lower Gornal employees at this time continued to grow with 56 staff on site by 1989.


New premises were built to establish both the pattern shop and foundry under one roof and by 1994 there were a skilled workforce of 90 located at Heath Mill, Wombourne.



The company had outgrown the Wombourne site and set up the Stanmore foundry on the outskirts of Bridgnorth, Shropshire as an additional facility: In total Grainger & Worrall were employing more than 150 people.


The expanding workforce had grown to 325 staff and during this year HRH Prince Edward visited presenting The Queen’s Award for Export to the company.
