Pulp-Formmaschine

The wet forming section consists of a series of wire screen covered wet forming dies mounted on a molding drum, and a matching set of transfer dies mounted on a transfer mechanism.The egg tray forming die is made up of rigid corrosive resistant metal or ABS engineering plastic and consists of many component parts that are drilled with small drainage holes and covered by pre-formed stainless steel screens.The forming die, mounted on the molding drum is rotated at a uniform speed, immersing it in a taper flow vat containing the pulp slurry of about 1% consistency of fibres in recycled water. A vacuum system attracts the fibres to deposit on the forming die screens as the suspending recycle water is drawn through the screen and drainage holes.When the matching transfer die comes into contact with the freshly formed fibre product on the forming die, there is a gentle puff of air from the forming die and a vacuum in the transfer die that gently lifts off and transfers the delicate wet formed products (about 75% water at this stage) onto the transfer die.
