The egg carton making machine is the most important machine in the egg tray production line. This machine adopts the principle of hot press forming. The paper pulp transformed into fiber suspension is evenly coated on the surface of the mold, and then it is pressed to form the egg tray.
The egg carton making machine can be divided into single-sided egg tray machines and multi-sided egg tray machines. The multi-sided egg carrier can also be divided into the 4-sided egg carton making machine, the 8-sided egg tray machine, and the 12-sided egg tray machine.
Shuliy egg tray machines have a production capacity of 1,000–7,000 pcs/h, meeting the needs of both small and large businesses. According to your requirements, we can provide either semi-automatic or fully automatic production line configurations.
So far, we have supplied egg tray machines to more than 50 countries and regions, including Tanzania, Saudi Arabia, Mexico, Chad, Uzbekistan, Cameroon, Zambia, and the Philippines. Our products have been highly praised by customers worldwide.
The structure of the egg carton making machine
The egg carton making machine is mainly composed of the drum-type molding motor, forming mold plate, transfer mold plate, vacuum pump, air compressor, storage tank, fuselage, and some other parts.
Drum-type molding motor
- Function: Provides stable power to drive the molding drum, ensuring uniform pulp adsorption on the mold.
- Data: Power range 7.5–15 kW, speed up to 1440 rpm, supporting a production capacity of 1000–7000 pcs/h.
- Key point: Motor power and speed directly determine production output and tray uniformity.
Forming a mold plate
- Function: Contacts the pulp and uses vacuum suction to form the initial shape of fruit trays.
- Data: Mold accuracy within ±0.05 mm; tray thickness 1.0–3.0 mm; one mold plate can form 2–12 trays per cycle.
- Key point: Surface precision affects tray smoothness and load capacity. High-quality stainless-steel molds last over 1,000,000 forming cycles.
Pulping Machine
- Function: Breaks down waste paper or plant fibers into pulp by dispersing, separating, and homogenizing fibers, providing uniform raw material for tray forming.
- Data: Pulp concentration 3–5%; fiber separation efficiency ≥ 95%; impurity removal rate up to 90%; suitable fiber length 0.2–1.5 mm.
- Key point: Ensures high pulp uniformity, improving tray strength by 20–30% and reducing thickness errors to within ±0.2 mm.
Vacuum pump
- Function: Provides negative pressure to吸 pull pulp fibers onto the mold surface.
- Data: Pumping capacity 100–300 m³/h; vacuum degree -0.06 to -0.09 MPa.
- Key point: Higher vacuum levels improve fiber density and tray strength.
Air compressor
- Function: Supplies compressed air for mold release, ensuring trays detach quickly and completely.
- Data: Operating pressure 0.6–0.8 MPa; air output 1–3 m³/min.
- Key point: Stable air pressure reduces breakage rates and increases efficiency.
Storage tank
- Function: Stores compressed air and stabilizes air pressure for continuous operation.
- Data: Tank volume 0.3–1.0 m³; stable output pressure 0.6–0.8 MPa.
- Key point: Prevents frequent compressor starts and prolongs system life.
Fuselage
- Function: Houses the motor, molds, pipelines, and control systems, ensuring overall machine stability.
- Data: Constructed from carbon steel or stainless steel; designed for continuous 24/7 operation.
- Key point: Strong structure ensures long service life (≥10 years).
Other auxiliary parts
- Pipeline system: Connects the vacuum pump, compressor, and molds; pipe diameter Φ25–Φ50 mm, ensuring fast air circulation.
- Electrical control system: PLC automation with timing precision ±0.5 seconds, offering one-button start/stop, production counting, and fault alarms.
How does the egg carton making machine work?
- Put the raw material into the pulper, add an appropriate amount of water, and make a fiber suspension after a long time of stirring.
- The water pump will suck the adjusted pulp into the water storage tank of the fruit tray forming machine.
- The pulp is adsorbed onto the forming mold by a vacuum system, and excess water slurry is transferred back to the storage tank via the vacuum adsorption system for reuse.
- Under the action of the air compressor, the molding die and the transfer mold are combined to press the pulp into the egg carton.
- The pressed egg tray will be sent out by the transfer mold to enter the next drying process.

Classification of egg carton making machines
Next, I will introduce the egg tray machines as single-side egg tray machines and multi-side egg tray machines in sequence, along with their technical parameters.
Single-sided egg carton forming machine
Introduction
The single-sided egg tray machine is also called a single-sided fruit carton forming machine, and the output is about 1000-2000 per hour. This machine has only one forming die plate, so it is also called a flap-type egg carton making machine. This model is currently one of the most popular models and is ideal for small and medium investors and novices.
