EVA + EPDM Die Ejection Foam - High Rebound Foam for Die-Cutting Applications

What Is Die Ejection Foam?

Die-cutting ejection foam provides stable and rapid rebound and ejection performance for high-speed die-cutting processes.

In flatbed die cutting, rotary die cutting, and other die-cutting applications, the foam quickly returns to its original thickness as the die moves away. This helps eject the cut material from the die, reducing the risk of material sticking to the die, remaining in the cutting area, or interfering with smooth cutting operations.

It is an important auxiliary material for maintaining stable and efficient production, particularly in high-speed, continuous die-cutting applications.

Die-Cutting Ejection Foam Features

1. Helps quickly release cut materials from the die
2. Improves material handling and ejection efficiency
3. Reduces the risk of materials sticking to or remaining in the die
4. Provides appropriate support between the die and the material being processed
5. Helps maintain process stability during high-speed, continuous die cutting
6. Allows rebound force to be adjusted according to different materials and die-cutting conditions

Select the Right Ejection Foam For Various Die-Cutting Requirements

A harder foam or stronger rebound does not necessarily mean better performance.

The appropriate ejection foam should be selected based on several factors, including die structure, cutting rule height, material type and thickness, die-cutting pressure, and production speed.

PHINOMENAL’s EVA + EPDM Foam for Ejection

Different die-cutting applications need various ejection foam characteristics. PHINOMENAL develops composite foam materials using EVA + EPDM, adjusting the formulation, density, hardness, and thickness to suit specific die-cutting materials and equipment conditions.

Our composite formulation blends the stable structure and processability of EVA with the elasticity and recovery features of EPDM. Through thoughtful formulation design, we balance support, rebound, and compression recovery performance for various temperatures, humidity levels, and industrial processing environments.
