Egg Tray Mold

In pulp egg tray production, the egg tray mold is a core piece of equipment in the forming process. It directly affects the tray’s shape, production efficiency, and cost, while its size and design are key concerns for customers.

Shuliy offers egg tray molds in various specifications and sizes, such as 6, 12, 20, and 30 cavities. The cavity diameter and depth can be customized according to egg size. Customers can also choose mold materials, including aluminum alloy, stainless steel, plastic, or combinations of these. Multiple tray styles and surface finishes are available for customization.

Our egg tray molds are durable, corrosion-resistant, and capable of continuous operation in humid environments. They produce uniform, sturdy trays with neat appearances, effectively protecting eggs and enhancing product competitiveness.

We have designed many egg tray mold for different customer to export to foreign countries. Such as shoe tray, electronic tray, wine tray, fruit tray, egg carton, etc, to foreign countries. Such as a shoe tray, an electronic tray, wine tray, fruit tray, egg carton, etc.

Design Features of Egg Tray Molds

What Makes a Good Egg Tray Product？

A good egg tray should balance protection, structural stability, and appearance consistency. Key characteristics include:

• Standard dimensions: Uniform cavity size and depth, with consistent overall tray dimensions for easy stacking, packing, and transport.
• Proper strength: Even wall thickness and good load-bearing capacity, reducing breakage during handling and stacking.
• Stable stacking: Well-designed single-layer or stackable structure that prevents slipping or collapse.
• Neat appearance: Smooth edges with no obvious burrs or damage, and clear, well-defined shaping.
• Good shock absorption: Cavities fit the egg shape closely, effectively cushioning external impact and lowering breakage rates.
• Eco-friendly and recyclable: Made from pulp materials that are recyclable and biodegradable, meeting environmental requirements.

How to Customize a Pulp Egg Tray Mold？

Define Egg Tray Specifications

• Number of cavities (e.g., 6, 12, 20, 30).
• Cavity size and overall tray dimensions to ensure compatibility with your production line.

Choose Mold Material

• Aluminum Alloy: Cost-effective with fast heat conduction.
• Stainless Steel: Corrosion-resistant, strong, suitable for high humidity or continuous production.
• Plastic: Low cost, ideal for trial runs or small batches.
• Combination Materials: Stainless steel in key areas and aluminum elsewhere for a balance of durability and cost.

Determine Tray Style

• Stacking type: Stackable or single-layer.
• Frame design: Standard or reinforced.
• Appearance customization: Embossed logo or special patterns.

Provide Production Parameters or Samples

• Forming machine model, capacity requirements, pulp characteristics.
• Samples or CAD drawings to ensure accurate dimensions.

Confirm Design and Proceed with Manufacturing

• Discuss material, dimensions, tolerances, and special requirements with the supplier.
• The supplier provides a 3D rendering or design confirmation before processing.

Mold Testing and Production

• CNC machining or wire-cutting followed by sample testing.
• Adjust edges, thickness, or drainage holes as needed.
• Once samples pass, the mold is ready for full production.

Application of Egg Carton Molds in Egg Tray Production Lines

Egg tray molds are the core components of an egg tray production line. They shape trays by water absorption or pulp pressing, ensuring consistent cavity and tray dimensions. Molds can be customized in various sizes and stacking structures to improve product quality and production efficiency.
