Abstract

Methods and apparatus for manufacturing a moulded fibre part include: immersing a wire mesh mould in a slurry bath comprising water and fibre particles; drawing a vacuum across the wire mesh mould to cause fibre particles to accumulate at the wire mesh mould surface yielding a moulded fibre part; transferring the moulded part from the slurry bath to a die press assembly; and drying and die cutting the moulded part in the die press assembly.
