Egg Tray Production Machine
An egg tray production machine forms prepared pulp into molded egg trays using dedicated product molds. It is the main forming unit between pulp preparation and drying, completing pulp forming, vacuum dewatering, and wet-tray transfer.
AGICO offers several machine configurations for new egg tray production lines, capacity expansion, and integration with existing pulp preparation or drying systems. The suitable model depends on the required output, tray design, mold arrangement, and overall production conditions.
How Does an Egg Tray Production Machine Work?
Prepared pulp is delivered to the forming section, where forming molds enter the pulp and vacuum draws the fibers onto the mold surfaces. At the same time, water is removed from the pulp to create the basic structure of the wet egg tray.
After forming, the wet tray is released or transferred from the mold and sent to the selected drying system. The forming cycle therefore connects pulp supply, mold forming, vacuum dewatering, wet-product transfer, and drying.
The mold determines the shape and cavity layout of the tray, while the machine configuration influences the production capacity and forming arrangement.
Main Functions of the Forming Machine
Pulp Forming
The machine uses dedicated molds to shape prepared pulp into egg trays. The mold design establishes the cavity arrangement, tray dimensions, and basic product structure.
Vacuum Dewatering
Vacuum removes part of the water from the formed pulp. This helps the wet tray retain its shape during transfer to the drying stage.
Wet-Tray Transfer
After forming, the wet trays are transferred from the forming position toward the next process. The transfer arrangement should be coordinated with the selected drying method and the layout of the production line.
Production-Line Integration
The forming machine can be used as an individual unit in an existing factory or as part of a complete egg tray production line. Depending on the project, supporting equipment may include pulp preparation, vacuum and air systems, drying equipment, stacking equipment, and packing equipment.

Mold and Product Planning
Mold selection should begin with the actual egg tray to be produced. A physical sample, drawing, or clear product specification can be used to confirm the cavity layout, tray dimensions, and intended egg arrangement.
If several tray designs will be produced in the same factory, each design should be reviewed separately. Different products may require different molds and may affect production changeover arrangements.
The mould quantity shown in the technical table should be considered together with the machine output and the required tray design. It is not sufficient to select a machine based on output alone.
Egg Tray Production Process
Pulp Preparation
Recovered paper or another suitable fiber material is processed into pulp and prepared for the forming stage.
Forming and Dewatering
The forming machine shapes the pulp on the installed molds and removes part of the water through vacuum.
Drying
Wet trays are dried using the selected drying method. The choice depends on production capacity, available space, energy conditions, and the factory layout.
Stacking and Packing
After drying, the finished trays can be stacked, counted, packed, and transferred for storage or shipment. The final handling arrangement depends on the required level of automation.

Choosing the Right Equipment Scope
The equipment scope should be determined by the condition of the existing factory and the intended production plan.
- For a forming-machine-only project, the main points to review are the existing pulp supply, vacuum and air systems, wet-tray transfer arrangement, drying equipment, and available connection conditions. For a new production line, the project should be planned as a connected system covering pulp preparation, forming, drying, stacking, and packing. The capacity and operating method of each stage should be compatible with the required production output.
Confirming the forming machine and its supporting processes together helps avoid gaps between individual equipment units.

FAQ
Q: What is an egg tray production machine used for?
A: It is used to form prepared pulp into molded egg trays and complete the initial dewatering and wet-tray transfer before drying.
Q: Is the forming machine supplied with a complete production line?
A: The forming machine can be supplied as an individual unit or included in a complete production-line solution. A complete line may also contain pulp preparation, vacuum and air systems, drying, stacking, packing, and other supporting equipment.
Q: What determines the output of an egg tray production machine?
A: Output is affected by the selected machine model, mold arrangement, tray design, forming cycle, and the conditions of the connected production processes.
Q: Can one machine produce different egg tray designs?
A: Different tray designs may require different molds. The feasibility of producing several designs should be reviewed according to the product dimensions, mold requirements, and production changeover arrangement.
Q: Can the machine be connected to an existing pulp preparation or drying system?
A: Integration can be considered after reviewing the existing pulp supply, equipment connections, transfer arrangement, drying method, and site conditions.
Q: What information should be provided before requesting a quotation?
A: Please provide the tray sample or drawing, target output, required equipment scope, raw-material information, drying preference, factory conditions, destination, and details of any existing equipment.
