1964Engineering 2 Oct. 438/2 A session at the fifth MTDRC was devoted entirely to high energy rate forming... The paper read last: ‘Petro-Forge Mk I-DRD’,..gave evidence of industry's keen interest in the development of a method of high energy operation which uses the internal combustion process for its power source. 1965Economist 18 Dec. 1354/3 The Petro-Forge has been sufficiently developed (it started under a DSIR grant in 1962) to show that even when working at slow speeds it will be cheaper and better than existing forging machinery. 1970Davies & Austin Devel. High Speed Metal Forming ii. i. 54 Multi-blow operation at one second intervals is..possible and enables the Petro-Forge to be used for large volume production of components. 1973E. C. Rollason Metall. for Engineers (ed. 4) vii. 129 In the Petro-forge the energy is derived from the combustion of a fuel/air mixture in the cylinder of an internal combustion engine. |
