A paper pulp molding machine turns used paper into strong, eco-friendly packaging. YG Machinery builds these systems for egg trays, fruit trays, and egg crates. Our range includes the small egg tray machine for startups and fast, high-output models for large factories. You feed in waste cartons or newspapers, and the machine pulps, forms, and shapes the product. With a paper tray forming machine, you can also make cup carriers and industrial packs. We design every unit to run with low labor and steady output. This guide shares key parameters, seasonal tips, drying comparisons, and troubleshooting steps. You will find practical advice to help you choose the right egg crate system for your budget.

Paper Pulp Molding Machine Technical Parameters
The table below lists our standard models. Each one works as an egg tray line or, with a mold change, an egg crate production unit.
| Model | YG-1*3 | YG-1*4 | YG-3*4 | YG-4*4 | YG-4*8 | YG-5*8 | YG-6*8 |
| Capacity (pcs/h) | 1000 | 1500 | 2500 | 3500 | 4500 | 5500 | 7000 |
| Forming Mould Quantity | 3 | 4 | 12 | 16 | 32 | 40 | 48 |
| Total Power (kW) | 40 | 40 | 50 | 60 | 130 | 140 | 186 |
| Electricity Consumption (kw/h) | 28 | 29 | 35 | 42 | 91 | 98 | 130 |
| Worker | 3-5 | 4-6 | 4-6 | 4-6 | 4-6 | 5-7 | 6-8 |
Capacity tells you how many pieces the machine forms in one hour. More forming moulds mean higher output per cycle. The worker count covers pulping, forming, and drying steps. Total power shows the installed motor load. Electricity consumption reflects real average use. These numbers help you calculate cost per tray and pick the right model.
How Seasons Affect Egg Tray Production?
- Hot and Humid Weather
High humidity slows natural drying. Wet trays may grow mold. Workers also tire faster in heat. You can add a metal drying line to keep production steady. Store dry pulp bales in a covered area. Clean forming moulds more often. This stops sticky buildup and quality drops. - Cold and Freezing Conditions
In low temperatures, wet trays can freeze and crack outdoors. Cold pulp slurry forms less evenly. Hydraulic oil thickens and the system may start slowly. Build a simple insulated room around the machine. Use a brick kiln or metal dryer to avoid freeze damage. Heat the pulp tank with a small electric heater. These steps protect your production line and let you run all year.


Egg Crate Manufacturing Machine Drying Methods Compared
- Natural Sun Drying
You spread trays on open ground or racks. The upfront cost is very low. Yet, you need a lot of land and many workers to collect trays. Rain, wind, and dust cause high losses. This method only fits a small egg tray machine with output under 1,500 pieces per hour. - Brick Kiln Drying
A brick chamber uses coal, wood, or gas for heat. It costs more to build than sun drying. Workers still load and unload trays by hand. Temperature control is rough. Some trays over-dry while others stay wet. Fuel and labor expenses add up over time. - Metal Drying Line
A single-layer or multi-pass metal dryer runs automatically. You need only two to three workers to watch the line. Trays move on a conveyor through controlled heat zones. Quality stays consistent. This dryer pairs well with medium-capacity egg crate machines. It costs more at first, but saves labor and cuts waste. - Multi-Layer Drying System
Trays travel on stacked conveyors inside an enclosed chamber. Heat recycles from one layer to the next. You save up to 60 percent of floor space. Power and fuel use per tray drop sharply. For high-output lines above 4,500 trays per hour, the multi-layer system delivers the lowest cost per piece over three years. The initial price is higher, yet long-term savings make it a smart choice.
When you plan your investment, think about land costs, labor costs, and yearly output. For many medium producers, the metal drying line offers a practical balance. For large-scale egg crate manufacturing, the multi-layer system brings the best efficiency.
Common Paper Pulp Molding Machine Faults and Troubleshooting
- Wet Trays Stick to the Mould
Dirty mould surfaces or weak vacuum cause sticking. Spray clean water on the forming dies each shift. Check vacuum lines for leaks. Clean out the filter. Adjust pulp consistency if fibers are too short. - High Breakage After Drying
Thin pulp, sudden high heat, or low-quality fibers raise breakage. Mix in long-fiber carton material. Lower the drying temperature in the first zone. Test different pulp blends. Keep a simple log to find the best mix. - Uneven Tray Thickness
Blocked nozzles or worn mould mesh lead to uneven pulp distribution. Flush the pipe system weekly. Replace damaged forming screens quickly. Thickness becomes uniform after these fixes. - Machine Trips or Motor Overheating
An overloaded chain or unstable power supply often trips the system. Lubricate all bearings and chains every day. Check voltage. Install a regulator if needed. Regular cleaning and inspections stop most breakdowns before they start.
How to Select an Egg Tray Machine or Larger System?
- Startups and Small Farms
If you produce fewer than 1,500 trays per hour, choose a small egg tray machine like YG-1*3 or YG-1*4. Pair it with sun drying or a simple brick kiln if you have cheap land and labor. This setup keeps your initial spend low. It recovers investment quickly. - Medium-Scale Suppliers
Output of 2,500 to 4,500 trays per hour fits a YG-3*4 or YG-4*4 with a metal drying line. The automatic dryer saves workers and raises quality. You can run a regional egg crate business with steady supply. The forming machine also allows you to make fruit trays and cup carriers with a quick mold swap. - Industrial High-Volume Producers
For 4,500 to 7,000 trays per hour, pick YG-4*8, YG-5*8, or YG-6*8. Add a multi-layer drying system and an automatic stacker. This full line gives you low unit cost and high daily output. Exporters and large farms trust these heavy-duty systems.
Think about your market, available space, and budget. Start with a clear production target. Then match the machine and dryer. Our team helps you draw a full layout and plan every step.
