With an illustrious past, South Yorkshire based Sizer Limited have combined engineering, innovation and quality manufacturing to produce a comprehensive range of pelleting press solutions. Originally established by Richard Sizer in 1899, a pioneering British engineer in Hull, England. His son, Albert Sizer, is recognized as the designer of the first ever pelleting press named 'the Cuber'. The design was patented in 1912 and Richard Sizer Ltd grew to becoming the global leader in animal feed pelleting systems. Approximately two decades ago, the company was bought by Sheffield-based Walden Engineering to become Walden Sizer Ltd. Since then the company has thrived in Sheffield, with support from firstly OSL Group Ltd and now the Newburgh Group. At Sizer, we pride ourselves with manufacturing the famous 'Orbit' Pellet Presses. The simple, robust designs have been continually improved to meet modern demands for cost effective quality and efficiency.
