Product Description
Egg tray machine is designed to be with 4 or 8 faces rotating drum, pulp mold die numbers on each drum can be 3, 4, 5, 6 pieces. We supply 8 models of eggtray making machines, such as ZMW3, ZMG4*4, ZMG3*8, ZMG4*8, ZMG5*8. Contact us now for the latest design and price if you are interested!
The well-ground paper pulp is conveyed to the egg tray machine through pipelines. Different styles of egg trays can be produced by using different molds on the egg tray molding machine, and molds can also be replaced to produce industrial packaging such as apple trays, wine trays, and seedling trays. After successful shaping, the basic shape of the egg tray is formed, but they are still wet and need to go through the next step.
The Egg Tray Forming Machine is the core host of a pulp molding production line that converts recycled waste paper into strong, shock-absorbing, 100% biodegradable paper egg trays. Using hydraulic pulping, vacuum negative-pressure forming, and hot-air drying, this egg tray forming machine produces 30-hole pulp trays, egg cartons, fruit trays, and industrial cushioning inserts from old newspapers, cartons, and office paper-at a raw material cost close to zero. For poultry farms, packaging factories, and recycling entrepreneurs in Nigeria, Kenya, India, Indonesia, Mexico, and Egypt, the egg tray forming machine is the most practical gateway into the fast-growing molded pulp packaging market.
How the Egg Tray Forming Machine Works
Pulping – Waste paper is shredded and beaten with water (0.8%–1.5% consistency) into uniform fiber slurry.
Vacuum forming – The slurry is drawn onto perforated molds by negative pressure (≈0.06 MPa); water drains away and fibers interlock into a wet tray blank in 12–25 seconds per cycle.
Transfer & press-dewatering – Semi-wet trays are demolded, squeezed to remove 60%+ moisture, then conveyed to the dryer.
Drying & curing – Natural sun drying, brick-kiln tunnel, or multi-layer metal dryer reduces moisture to 10%–12%.
Stacking & packing – Auto counter, stacker, and bundler finish the line.

Typical Buyer Questions We Answer
Can the egg tray forming machine run on waste cardboard only? → Yes, with a hydrapulper and consistency control.
Does it need a metal dryer? → Not always; sun drying works for small units in dry climates, metal dryer is for 24/7 automatic lines.
Can I produce egg cartons with lids? → Yes, by swapping to carton molds and adding a hot-press station.
