Can An Egg Tray Machine Make Biodegradable Pulp Seedling Trays With Custom Molds?
Many pulp molding factory owners run egg tray machines and look for new profitable products. A frequent question: can an existing egg tray machine produce pulp seedling trays just by installing custom molds? This post covers its feasibility, mold requirements and business benefits.
How an egg tray machine produces pulp seedling trays?
Egg tray machines and pulp seedling tray equipment share the same pulp molding principle: waste paper pulp, vacuum forming and drying.
You only replace the egg tray molds with custom seedling tray molds. Wet pulp forms the grid cell structure of pulp seedling trays, then goes through dewatering and drying to get compostable paper nursery trays.
The main host, pulp tank and dryer stay the same, only minor parameter tuning is needed. Check our machine page: versatile egg tray forming machines.
Key design requirements for pulp seedling tray molds
Pulp seedling tray molds differ from egg tray molds:
- Independent planting cavities, available in 6/8/12/24 cell sizes
- Bottom drainage holes for irrigation
- Anti-stick surface coating for smooth demolding
- Stackable structure for easy packing and shipping We support custom molds based on your samples or drawings.
Important limitations to consider
Switching is possible, but there are constraints:
- The machine’s forming area must fit your tray outer size
- Pulp seedling tray is often thicker; adjust drying settings
- Adjust pulp formula to improve tray toughness for nursery use
- Hourly output will change with the new mold layout
Pulp seedling trays VS plastic plug trays
Pulp seedling trays are fully biodegradable. Farmers can transplant seedlings together with the tray directly into soil to avoid root injury and boost survival rate.
Plastic trays face tighter plastic bans worldwide and require cleaning and recycling. This makes pulp seedling tray a high-demand eco alternative for greenhouses.
Simple steps to switch production
- Confirm your machine’s max forming dimension
- Send samples or drawings for mold quotation
- Produce and test the custom seedling mold
- Install the mold and adjust pulp, vacuum and drying settings
- Run trial production and start mass production after passing tests
Should you invest in seedling tray molds?
If you already own an egg tray machine, adding custom molds is a low-cost way to expand your product line. You can flexibly switch between egg trays and pulp seedling trays based on market orders.
When egg tray competition is intense, pulp seedling tray open new sales channels for nurseries and agricultural suppliers.
Final verdict
Yes, an egg tray machine can make biodegradable pulp seedling trays with suitable custom molds, as long as the forming size matches your specs. It is a great upgrade to tap into the fast-growing eco nursery supply market.
