With its operation of different kinds of wood raw materials, wood pellets could be squeezed and produced through these holes in a certain length. On account of high quality of the alloy steel, die set in GEMCO would serve for almost 800 hours. More than that, every details have been done a comprehensive test strictly so that all the errors and flaw have been narrowed in a minimum value.
