The 8 side egg tray machine, also known as a large-scale egg tray forming machine, is equipped with an 8-sided rotary drum. It enables high-speed, continuous production, making it especially suitable for factories with medium to large-scale output requirements.
SL-4000-4X8 can produce about 4000pcs egg shells per hour. Egg plate molds can be customized according to the buyer’s requirements. This equipment can be continuously produced and ensures production capacity. In addition, because the whole production process is recycled waste paper, no pollution sources, so it is called green environmental protection machinery.
Model SL-5000-5X8 egg tray machine can produce about 5000pcs egg trays per hour. It is 45 angle and an eight-plate rotary tray machine. Eight plates form a board, and all systems can be connected. This transfer arm makes a 90-degree reciprocating motion. The working efficiency is very high.
The SL-7000-6X8 is our company’s highest-capacity egg tray forming machine, with an output of up to 7,000 pieces per hour. It features an 8-sided rotary drum with 6 egg tray molds on each side, making it ideal for efficient, large-scale production in big factories.

How Does an 8 Side Egg Tray Machine Work? Structure and Production Process
The 8-sided tray making machine mainly consists of the pulping system, forming system, drying system, and packing system.
8 Side Egg Tray Machine Structure
An 8 side egg tray machine uses an octagonal rotary drum as its forming core. Each of the eight drum faces carries a row of aluminum forming molds, and the whole drum rotates continuously through the pulp vat, vacuum forming station, and ejection zone.
The mold layout depends on the model:
- SL-4000-4×8: 4 molds per side × 8 sides = 32 forming molds
- SL-5000-5×8: 5 molds per side × 8 sides = 40 forming molds
- SL-7000-6×8: 6 molds per side × 8 sides = 48 forming molds
This high-density layout is what allows the machine to reach 4,000–7,000 pieces per hour. The drum is driven by a heavy-duty gear system with wear-resistant bearings. A vacuum pump, air compressor, PLC control cabinet, and transfer conveyor are integrated into the same frame.
The complete production system also includes:
- Pulping system – hydrapulper, pulp pump, and consistency regulator
- Forming system – 8-sided rotary drum with vacuum molds
- Drying system – sun drying racks, brick kiln, or multi-layer metal dryer
- Packing system – hydraulic press and strapping unit
Production Process
Step 1: Pulp Preparation
Waste paper, cardboard, or pulp board is loaded into the hydrapulper with water at a ratio of about 1:4. The blades run for 15–20 minutes until the mixture becomes a smooth fiber slurry. The pulp concentration is adjusted to 2–3% before it is pumped into the machine’s pulp tank.
Step 2: Mold Immersion and Vacuum Forming
As the 8-sided drum rotates, each mold face dips into the pulp tank one after another. A vacuum pump draws pulp fibers onto the mold screen, shaping the wet tray inside the mold cavity. Because eight sides are working in sequence, forming never stops.
Step 3: Dewatering
After leaving the pulp tank, the formed tray stays on the rotating drum for a few seconds. Gravity and vacuum suction remove excess water. The wet tray still contains about 50–60% moisture when it reaches the ejection point.
Step 4: Automatic Transfer
At the transfer position, the vacuum is released and positive air pressure blows the wet tray off the forming mold onto a transfer conveyor or a transfer mold. The empty mold then continues to the next forming cycle.
Step 5: Drying
Wet trays move into the drying system. Depending on the setup, this can be:
- Sun drying – trays dry on racks in open air for 2–3 days
- Brick kiln dryer – hot air at 80–120°C dries trays in 45–90 minutes
- Multi-layer metal dryer – automatic belt dryer with the smallest footprint
Moisture is reduced from 50–60% to below 12%.
Step 6: Stacking and Packing
Dried trays are stacked and fed into a hydraulic packing machine. The press compresses the stack by 30–40% and straps it for transport. This reduces shipping volume and warehouse space.

How to Make Egg Trays with an 8 Side Egg Tray Machine?
Raw materials are mainly straw pulp, slurry, bamboo pulp, wood pulp, waste paperboard, waste paper box paper, waste white paper, paper mill tail pulp waste, etc. The raw material has a wide range of source and is easy to collect. The egg tray machine is the main machine for the egg tray production line.
Feeding the pulp in the pulp pool into the molding machine. The pulp is absorbed by the vacuum system, and the pulp is molded by the mold on the equipment. The water is absorbing and transporting back into the pulp pool through the vacuum pump. The water can be recycled.
After the mold adsorbs the water slurry, the transfer mold is discharged through the air compressor. The finished product is blown from the forming mold onto the transfer mold, and then it is sent out by the transfer mold.
How Much Does It Cost to Produce Egg Trays? Cost Analysis
| Cost Item | Description | Unit Cost per Tray (RMB) |
| Raw Material | 1 ton of waste paper can produce 12,000–15,000 trays (based on tray weight). Based on 80g per tray: 1,000,000g ÷ 80g = 12,500 trays Waste paper price: ¥1500/ton → 1500 ÷ 12,500 = ¥0.12 per tray | ¥0.12 |
| Labor | Sun drying: 6 workers; drying by machine: 4 workers. In China, Labor is often calculated by piecework: approx. ¥0.02 per tray. | ¥0.02 |
| Electricity | Varies with capacity and power consumption. Higher output means lower cost per tray. | ¥0.02 |
| Drying Fuel | Coal (5000 kcal/kg) Wood (4000 kcal/kg) Natural Gas (8900 kcal/m³) Diesel (11,900 kcal/liter) | ¥0.03/pc ¥0.03/pc ¥0.06/pc ¥0.08/pc |

Frequently Asked Questions
What is the difference between a 4-side and an 8-side egg tray machine?
A 4-side machine has four forming faces on the rotary drum and is ideal for 2,000–3,000 pcs/h. An 8-side machine has eight forming faces and higher mold density, making it suitable for 4,000–7,000 pcs/h.
How many workers are needed to run an 8 side egg tray machine?
A complete 8-side line normally needs 3–5 workers per shift. One operator monitors the control panel, one handles raw material feeding, and the rest manage drying and packing.
What is the power consumption per 1,000 trays?
Power use is approximately 0.0125–0.013 kWh per tray, or 12.5–13 kWh per 1,000 trays. Drying fuel is calculated separately based on coal, diesel, gas, or electricity choice.
Can the 8 side machine produce products other than egg trays?
Yes. By changing molds, the same machine can produce fruit trays, shoe trays, wine bottle trays, electronic component trays, and disposable food containers.
How much floor space does an 8-side egg tray production line need?
The forming machine itself needs about 30–50 m². With a brick kiln dryer, the total workshop area is usually 600–800 m². A multi-layer metal dryer reduces this to 200–300 m².
What is the typical delivery time after placing an order?
Standard models need 20–30 working days. Custom voltage or special mold designs may add 5–10 working days. Sea shipping time depends on the destination port.
What spare parts should be kept in stock?
We recommend keeping mold screens, vacuum pump seals, air compressor filters, bearings, and conveyor belts in stock. These parts wear gradually and are easy to replace.
Can the machine run in hot and humid climates?
Yes. The electrical cabinet is waterproof and dustproof. Stainless steel parts resist corrosion. In very humid areas, we recommend a metal dryer instead of natural sun drying.
