Who Are We?

Sumitomo (SHI) Demag Plastics Machinery UK Ltd.

Everything from a single source

Sumitomo (SHI) Demag UK Ltd, is a wholly owned subsidiary of Sumitomo (SHI) Demag Gmbh, Schwaig, Germany.


Hamilton Machinery Sales was the original agency company for Ankerwerk injection moulding machines in the U.K. and Ireland and started trading with Ankerwerk in 1957. In 1971 Demag acquired one hundred per cent of Ankerwerk Gebr. Goller GmbH and Albert Stübbe, two of the major suppliers of injection moulding machines in Europe. As a result of the acquisition of Ankerwerk, the manufacturing facility in Nürnberg was closed and production was transferred to its second plant in Schwaig, 15 km from Nürnberg, where a major expansion was implemented.

At the time the Ankerwerk machines were sold in the U.K. and Ireland by Hamilton Machinery Sales and Stübbe machines were sold by Mortimer Machine Tools Limited. As a result of the outright purchase of Ankerwerk and Stübbe by Demag AG, Demag formed a joint company with Hamilton Machinery Sales in 1974 in the U.K. to sell both ranges of machines. The new company, Demag Hamilton Limited successfully integrated the sales of both types of machines within the organisation and in 1979, as a result of AG purchasing Demag, the Company changed to Demag Hamilton Limited.

In 1980 the Ankerwerk and Stübbe ranges were superseded by the Demag 'D' series of machines.

In 1990 in another major move to establish them in the small machine market Demag purchased the Kuasy factory situated in Wiehe in the former eastern Germany. This company in Wiehe had been a major supplier of injection moulding machines to the eastern bloc and had delivered more than 10,000 injection moulding machines to Russia. A DM 50 million investment was made in the Wiehe factory by Demag which has resulted in one of the most automated injection moulding machinery factories in the world.

At the K'92 Düsseldorf exhibition Demag Kunststofftechnik introduced the current ERGOtech range of injection moulding machines to supersede the very well-established 'D' machine range. These new ERGOtech models were introduced in both the Wiehe and Schwaig factories. The Wiehe factory builds machines up to 110 tons locking force and the Schwaig factory builds machines from 120 to 4000 tons clamp force.

In 1993 purchased the Van Dorn company in Strongsville, Ohio, U.S.A. The new company was called Van Dorn Demag and at the time Van Dorn was the second largest manufacturer of injection moulding machines in the U.S.A. (Cincinnati being the largest).

In 1994 a major investment was made in the Van Dorn Demag company to double the size of the assembly plant for its toggle injection moulding machines. In 1994, the Demag Wiehe factory produced more than 900 machines, the Demag Schwaig factory 600 machines and the Van Dorn Demag factory 850 machines.
