New patent application published for: A PROCESS FOR FORMING A MOULDED PULP FIBRE PRODUCT

A process for forming a moulded pulp fibre product involves creating a slurry deposit, reducing the liquid content of the slurry deposit to form a pulp fibre pre-form having an initial form, and pressing the pulp fibre pre-form in a tool set to further reduce the liquid content of the pulp fibre pre-form and deform the pulp fibre pre-form from the initial form to a secondary form. A first mould tool has a surface that includes primary regions to apply a first reduction in material thickness, and secondary regions in which the surface is shaped to cause a change in the material thickness of the pulp fibre pre-form that is less than the first reduction. Portions that are formed between the primary regions and a second mould tool have higher density, compared with portions that are formed by the secondary region and the second mould tool.
