Pulping
- Ingredients added to giant blender
- Recycled paper of all kinds
- 65 deg C water
- Blend for 20 minutes
The pulp exits from bottom through a screen that screens out plastic & metal
Cavity Mold
- Cavity mold (formation mold) descends into paper pulp mixture
- Vacuum pulls fiber on to mold
- Water jets rinse off the excess
Transfer Mold
- Transfer molds are lubricated with a water based lubricant
- So flats do not stick
- Vacuums the mold off of the cavity mold
- Vacuum off / blow into mold to place on conveyer
Mold Constuction
- Made from bronze, aluminum, or plastic
- Covered with stainless steel mesh
- For even vacuum
Drying Parts
- 6-12 minutes at 205C Heat
- Time depends on weight
- Evaporates water
- Bonds fibers for strength
Watertight Parts
- Chemicals added to make liquid tight
- Molded like reverse blow mold
- Mesh on inside of mold
- Vacuum applied sucks pulp into mold
- Water jet washes excess pulp
- Dried longer so water tight chemicals cure
Please tell me who can make one of these mesh molds for me.
I can make the vacuum table. I am a DIY person.
Thanks
