Egg crate making machine is a paper pulp molding machine that uses molds to form waste paper pulp into trays. Since egg trays account for most applications in this product category, the equipment is commonly used as an egg tray machine or egg tray production line.
The documented models range from 1500 to 7000 pcs/h, with different power requirements, paper and water consumption, drying configurations, machine weights, and dimensions. The available models include YG-1500-4X1, YG-2500-3X4, YG-3000-4X4, YG-4000-4X8, YG-5000-5X8, and YG-7000-6X8.
The equipment consists of three main sections: pulp preparation, forming, and drying. The forming section uses a main machine, vacuum pump, and air compressor to shape pulp on the mold before transferring the finished trays to trays or a conveyor.

Egg Tray Manufacturing Machine Working Process
The egg crate making machine works through three main sections: pulp preparation, forming, and drying.
1. Pulp Preparation
Waste paper and water are processed in the pulper at a documented ratio of 1:10. The pulp then enters the mixing tank, where materials such as pigments and waterproof adhesive can be added. A pulp pump transfers the mixture to the supply tank, where water is added to reach a pulp concentration of 3%-5%.
2. Pulp Forming
The forming section consists of the main machine, vacuum pump, and air compressor. Negative pressure from the vacuum pump draws the pulp onto the mold while excess water passes through the stainless steel mesh.
After vacuum dehydration, the molded paper tray is transferred by positive air pressure to the transfer mold and then blown onto trays or a conveyor.
3. Drying and Stacking
The formed trays enter the drying section through trays or a conveyor. The documented drying process uses temperatures of approximately 180-220 degrees C for 15-20 minutes, depending on the drying configuration. After drying, the trays are counted, stacked, and packed.

Egg Paper Tray Making Machine Drying Options
The egg crate making machine can use different drying methods according to the documented equipment configuration.
| Drying Method | Main Characteristics |
| Natural Drying | Uses sunlight and natural air; requires more space and labor |
| Drying Box | Uses drying boxes and carts; production can continue in windy or rainy weather |
| Civil Construction Drying | Conveyor-based drying tunnel; generally 40- 70 m long |
| Multi-Layer Metal Drying | Six-layer drying chamber; approximately 18m long |
Natural drying does not require an external energy source but requires significant drying space and manual labor.
The drying box can accommodate 10-12 carts, with each cart carrying approximately 90-100 trays according to the supplied document.
For civil construction drying, the formed trays pass through a drying tunnel for approximately 15 minutes at 180-200 degrees C. The tunnel is generally 40- 70 m long.
The multi-layer metal drying system uses six layers and approximately 25 minutes of drying at 180-200 degrees C. Its documented drying chamber length is 18m with six layers.
Egg Carton Machine Core Features
1. Multiple Production Capacities
The egg crate making machine series covers capacities from 1500 to 7000 pcs/h. This gives buyers several documented configurations for different production requirements.
The YG-1500-4X1 is rated at 1500 pcs/h, while the YG-7000-6X8 reaches 7000 pcs/h.
2. Waste Paper as Raw Material
The egg crate making machine uses waste paper products as the main raw material for pulp preparation.
The supplied document lists waste paper, cardboard, books, newspapers, magazines, paper bags, and other paper products as available raw materials. A4 paper and books are specifically identified as suitable materials.
3. Integrated Forming Process
The equipment combines pulp preparation, vacuum forming, positive-pressure transfer, drying, counting, stacking, and packing into a continuous production process.
The exact configuration depends on the selected model and drying method.

Egg Tray Manufacturing Machine Application
The machine is primarily intended for molded paper trays. Because the document states that egg trays account for more than 80% of this industry, the equipment is commonly referred to as an egg tray machine or egg tray equipment.
The same pulp molding technology can also be used for other molded paper products, such as coffee cup holders and fruit trays, when equipped with the corresponding molds.
Before selecting a model, customers should confirm:
- Required production capacity
- Available raw materials
- Required mold
- Drying method
- Available production space
- Required power configuration
