This machine is a single-plate automatic sorter that performs the most important single-plate sorting that determines the quality in the plywood manufacturing process. Just 10 years after having exhibited at Wood Eco Tech 2009, it became a model with a delivery record of 20 units in various specifications to date. From Ten years ago, with the development of camera performance and computer processing power, our unique algorithm can be realized further, and treasure hunters have continued to evolve. In addition to new image processing technology, in order to meet the needs of users, we have expanded and updated the defect detection elements (cracks, holes, nodes, nests, stains, molds and worms) of discrimination criteria in veneer sorting.
