Egg tray making machines transform waste paper into environmentally friendly paper pulp packaging containers. The core process mainly includes three steps: pulping, forming, and drying.
1. Core Process and Raw Materials
* Raw Materials: Various types of waste paper (waste newspapers, cardboard boxes, scraps).
* Process: Waste paper is pulped and the pulp concentration is adjusted → vacuum adsorption forming → drying and shaping.
* Environmental Protection: Production water is recycled, with no wastewater discharge; the finished product is biodegradable.
2. Equipment Types and Capacity
Based on scale and investment, egg tray making machine is mainly divided into two categories:
* Reciprocating Egg Tray Making Machine: Suitable for small to medium-scale or multi-variety production (flexible mold changing); Estimated capacity: Approximately 400-1000 trays/hour
* Rotary Automatic Egg Tray Making Machine: Suitable for large-volume production of a single product (high efficiency, automation); Estimated capacity: Approximately 4000 trays/hour up to 10000 pieces per hour
3. Investment and Cost Estimation (Taking a Medium-sized Line as an Example)
* Equipment Investment: Prices vary greatly, ranging from approximately 70,000 RMB for small equipment to hundreds of thousands or even millions of RMB for large fully automatic lines.
* Energy Consumption Estimation: A production line with a capacity of 3000 trays/hour has a total installed power of approximately 185kW, consuming approximately 110 kWh per hour.
* Labor Costs: A fully automatic line requires only 5-6 people per shift.
4. Real-world Cases and Benefits
* *Project Case: An investment of 3.1 million yuan was used to build a standardized factory, producing 100,000 egg trays per day, with an annual output value exceeding 9 million yuan, creating jobs for 10 villagers (monthly income of 2,000-4,000 yuan).
* *Project Case: An investment of 2.8 million yuan was used to produce 220,000 egg trays per day, with annual sales reaching 30 million yuan, creating jobs for over 20 people.
5. How to choose egg tray making machines ?
* *Consider Scale: Initially, a reciprocating egg tray machine can be selected; for large-scale egg tray production, a fully automatic rotary drum egg tray production line should be chosen.
* *Consider Products: If you plan to switch to producing fruit trays, cup holder trays, etc. in the future, you need to consider the flexibility of equipment mold changing and reserve a hot press interface.
* *Consider Energy: Drying can be done with diesel, steam, heat transfer oil, natural gas, coal, or wood chips. Choose the drying method and heat source fuel based on local energy costs.
