YITAI is a global one-stop die-making solution provider, offering a comprehensive supply chain that covers everything from laser cutting machines, CNC routers, benders, and sponge cutters to cutting rules, plywood, rubber, sponge, and more.
In the die-cutting industry, sponge plays a crucial role in ensuring precision, protecting blades, and improving production efficiency. Sponge is a versatile cushioning material designed to safeguard delicate surfaces during cutting while maintaining sharp, accurate die cuts. It is widely used in processing materials such as paper, cardboard, plastics, and foils, ensuring high-quality finished products.
Sponges are available in various densities, thicknesses, and materials, allowing customization for different industrial packaging needs. Their excellent compressibility and resilience ensure even pressure distribution, enhancing die-cutting performance. Additionally, sponges are lightweight and easy to handle, making them ideal for high-speed production environments.
By integrating high-quality sponges into die-cutting operations, manufacturers can boost productivity, reduce material waste, and improve cost-efficiency. Below, we explore the different sponge grades used in industrial packaging die-cutting.
Standard PU Foam
Density: Low (20-30 kg/m³), moderate elasticity, cost-effective.
Grades: Soft, medium, and hard variants for light-duty die-cutting.
High-Resilience PU Foam
Density: 30-50 kg/m³, superior rebound and durability, suitable for high-speed die-cutting.
EPDM Sponge
Properties: Excellent weather & ozone resistance (-50°C to 150°C).
Grades: Medium-high density (40-60 kg/m³), Shore A 20-90 hardness.
NBR Sponge
Properties: Oil-resistant, ideal for food packaging and oily material processing.
Cross-Linked PE Foam (XLPE)
Properties: Closed-cell structure, waterproof, dustproof.
Grades: Medium-high density (30-200 kg/m³), available in standard & anti-static versions.
Low-Density Sponge (20-40 kg/m³)
Best for lightweight materials (e.g., paper, adhesive films).
Medium-Density Sponge (40-60 kg/m³)
General-purpose use (cardboard, PVC, thin plastics).
High-Density Sponge (60+ kg/m³)
Heavy-duty cutting (corrugated board, rubber sheets).
Anti-Static Sponge
Prevents static buildup (surface resistance: 10⁶–10⁹ Ω), used in PCB & electronics die-cutting.
High-Temperature Sponge (Silicone Foam)
Withstands 200°C+, ideal for laser die-cutting & hot processing.
Food-Grade Sponge
FDA-compliant, non-toxic, odorless—suitable for food packaging.
Strip Sponge
Installed along die blades (Shore A 30-50 hardness).
Perforated Sponge
Improves air release, ideal for film & adhesive materials.
