Egg trays fail when eggs are supported at isolated contact points instead of along their natural curvature. Poorly designed molds create stress concentrations that increase cracking during stacking and transport.

This mold uses controlled cradle geometry and consistent depth to distribute load evenly across each egg. When combined with stable nesting design, this significantly improves tray performance without increasing material usage.

Engineered for Egg Tray Production Lines

Cavity geometry is developed based on egg size standards, stacking height, and transport conditions. Draft angles and flange dimensions are tuned to support smooth de-nesting and reduce line stoppages on automated equipment.

Tool layouts are created using 3D CAD, allowing optimization for cavity count, sheet utilization, and cycle time. Surface polishing and edge radiusing improve plastic flow and reduce stress marks, particularly when running recycled PET.

Es importante señalar que rPET variability can affect clarity and thickness consistency. In most cases, these issues are addressed through forming parameter adjustments rather than tooling changes.

Preguntas frecuentes

Can this mold be customized for different egg sizes or tray counts?
Yes. Cavity dimensions and layout are customized based on egg size standards and packaging requirements.

What plastic materials can be used with this mold?
The mold is suitable for PET, rPET, and PS, depending on regulatory and cost considerations.

How does the mold affect tray nesting and de-nesting?
Draft angles and flange geometry are designed to control nesting depth and support reliable de-nesting on automated lines.

Is this mold suitable for recycled PET?
Yes, but forming parameters may need adjustment due to rPET sheet variability.

What is the typical tooling lead time?
Lead time depends on cavity count and complexity and begins after design approval.
