Egg tray manufacturing machines are core production equipment in the fields of poultry egg packaging and environmentally friendly pulp molding. The key to selecting one is matching production capacity, budget, available space, and long-term operational needs. The current market offers a wide variety of models, ranging from semi-automatic small machines to fully automatic high-speed production lines, with significant differences in parameters, configurations, and prices.
YG offers customized equipment configuration and factory layout planning services tailored to each client’s factory size, budget, target capacity, and energy availability. Furthermore, YG egg tray machines feature strong flexible production. In particular, simple mold replacement allows one machine to make egg trays, egg boxes, fruit trays, bottle trays, industrial liners, and seedling cups.

Working Principle of Egg Tray Manufacturing Machine
1. Raw Material Preparation – Waste Paper Pulping
Raw materials like waste cartons and newspapers enter the pulper with proportioned water and are stirred to form a uniform fiber suspension. The vibrating screen removes impurities, and the refiner improves pulp quality. Operators then add specialized processing additives to prepare a standard 1%–3% concentration of qualified pulp, and deliver it to the forming machine pulp tank for subsequent production. Besides, waste paper recycling effectively cuts raw material costs.
2. Vacuum Forming – Wet Tray Forming
The pulp is pumped to the forming mold. The vacuum system generates negative pressure, causing the pulp fibers to be evenly adsorbed onto the mold surface, forming a wet egg tray. Excess water is recycled. Rotary drum continuous forming and roller extrusion forming ensure uniform thickness and structural integrity of the wet tray, with a forming accuracy error of ≤0.1 mm.
3. Transfer and Dewatering – Wet Tray Transfer
The formed wet egg tray is demolded by a transfer mold using air pressure or mechanical force and transferred to the drying system’s conveyor belt. The transfer process completes preliminary dewatering. It reduces wet tray moisture to avoid drying deformation; meanwhile, it also keeps products perfectly intact.
4. Drying and Curing – Finished Product Shaping
Wet trays enter a multi-layer drying line, where they are dried in sections at 50℃-80℃ with hot air circulation, reducing the moisture content to the acceptable standard of 8%-12%. Meanwhile, waste heat recovery technology improves thermal efficiency by more than 30%; in addition, it keeps the drying cycle within 20 minutes. After drying, the trays are trimmed, smoothed, and stacked to become ready-to-use finished egg trays.
Key Considerations for Selecting an Egg Tray Manufacturing Machine
1. Matching Capacity and Production Scale
- Daily demand 10,000-50,000 pieces: Choose a YG semi-automatic model to control investment costs.
- Daily demand 50,000-200,000 pieces: Choose a YG medium-sized fully automatic machine to balance efficiency and cost.
- Daily demand 200,000-500,000 pieces and above: Choose a YG best-selling 8-sided rotary drum machine or a YG double-roller high-speed machine to meet large-scale production needs and ensure capacity and stability.
2. Focusing on Core Configuration and Quality
- Molding System: Vacuum degree ≥ -0.08MPa, ensuring uniform egg tray density and preventing breakage.
- Drying System: Temperature control accuracy ±5℃, segmented temperature control to prevent deformation and cracking.
- Control System: PLC intelligent control with fault alarm, parameter storage, and remote monitoring functions.
- Mold Material: Wear-resistant alloy steel with polished surface, lifespan exceeding 500,000 cycles.
3. Verify After-Sales Service and Technical Support
- Choose reputable egg tray manufacturing machine manufacturers like YG, which provide installation tutorials, technical guidance, and comprehensive after-sales service.
- 48-hour domestic response time, overseas remote assistance, and fast parts delivery ensure production continuity.
