  • The expansion of the manufacturing sites in Hobart and Bendigo.

  • Further opportunities for regional jobs across the Hobart, Wodonga and Bendigo manufacturing facilities - an estimated 18 per cent increase in jobs across these sites over the next three years.

Derwent News - Derwent Foundry Turns 180

180 Years.png

The Tasmanian Foundry was purchased by the Evans family in 1997 and since then has been upgraded and modernised on a continuing basis.

Derwent Foundry is now a registered entity of Derwent Industries Pty Ltd.

Clamp News
Aust Made.jpg

Derwent Clamps® and Derwent Couplings® were recently added into the Derwent range with a new state of the art robotics manufacturing facility being established in North East Victoria.

The Stainless Steel Clamps (Kawandah®TM - Cocky Clamp) were developed for the Australian and export markets  by the Evans Group of companies in 1981, in Wangaratta Victoria. The iconic logo of the cockatoo (Current trademark) is the logo we are still proud to use today to represent the range. The stainless steel couplings were originally developed in the 1990’s by the Evans Group, which was an iconic change to how the market saw the traditional coupling. A world leading Australian innovation, that revolutionized coupling design and manufacture and one that has stood the test of time.


Derwent Industries new facility in North East Victoria, will integrate multiple elements to form complete custom-automated production cells in line with Industry 4.0 concepts, maximising automation and data exchange in the manufacturing process. This signals a major advancement over its previous technology advancements and manufacturing capability and will enable the company to not only look to replacing the imported products currently supplying the Australian Industry but to move towards the establishment of a major export capability.
