Owen Greenings & Mumford Ltd (OGM) was founded in 1962 in a workshop in Oxford with a single injection moulding machine.

Over the next 40 years, Bev Wightman developed the business successfully with growth based on outstanding customer service, continuous innovation, the highest quality and a commitment to long term partnerships that add real value to every customer.

In 2001, Paul Wightman took over the business from his father and as Managing Director has continued to uphold the same core values.

More recently, ongoing success has led to the creation of a diversified group of companies within the OGM Holdings Group. Manufacturing from four factories in the UK, OGM now operates in Oxford and South Wales, and owns businesses in Bedford and Derby producing catering consumable products and printed films for packaging.

OGM founded – the business was founded by Bev Wightman along with Ivan Owen,  John Mumford and Don Shepherd. The company operated with one moulding machine and one tool to produce its own design of plastic door handle. Premises were shared with Owen Mumford Ltd in Woodstock.


The trend for stainless steel tableware in homes in the UK leads to the development of the OGM TableMat range – a fusion of a plastic injection moulded base and a hand woven stainless steel top. Sales grow with 6 assembly workers employed to produce the TableMat. Profits from this product  and others in the range enable further investment in injection moulding machines and eventually new premises.


Trade moulding for other companies starts. Ever Ready Ltd become the company’s largest customer. We produce their torches and cycle lamps.


The business moves to a new 300 m2 factory in Eynsham as Trade Moulding grows.


The business is extended by 600 m2 to meet demand for Trade Moulding.


The business is further extended and new offices are added to the building.


Another extension of the buildings – this time we increase the warehouse.


Our relationship with Siemens begins as we start to supply 50,000 Housings pa for the MM1 range of products.


A lease is signed for new buildings in Eynsham adjacent to the existing factory adding a further 600 m2 of warehouse space. Planning permission is granted for a further 600 m2 extension to the building and conversion to a factory.


We sever ties with our largest customer in the automotive industry as calls year on year for price reductions means the business is not considered viable for the future. We focus on growth with electronics, general industrial and medical customers.


The new factory and offices are completed and production starts.


The cleanroom is built for Medical product assembly of wound drainage devices. Eventually 12 people are employed on 3 shifts to produce 50,000 assembled devices per month. We handle the post assembly irradiation and the devices are supplied as sterile product.


We extend again – a tool room is added.


We win Siemens Supplier of the Year.


The formation of OGM Holdings Ltd and acquisition of Terinex Ltd in Bedford doubles the size of the company and provides diversification into new sectors.

By May the complete move of all operations and staff has occurred and we have a company ready for the future.
