What This Machine Solves
Three production problems eliminated by this machine — with engineered, measurable solutions.
Standard EPS beads cannot achieve density below 8 kg/m³ — limits product cost optimization for low-density applications
High-expansion beads achieve 4-8 kg/m³ density for super-light packaging — 40-50% lighter than standard insulation grade.
Lightweight packaging customers (fish boxes, large protective inserts) need lowest possible density for shipping cost optimization
High-expansion variant cuts material cost per unit volume by 30-40% — directly improves margin on low-density products.
Engineered Performance Advantages
Every advantage backed by measurable specs — no marketing claims without data.
Higher expansion = lower density = lower material cost per unit volume.
Lowest densities for super-light packaging.
Direct margin improvement on low-density products.
