Description
EVA Foam Sheet Calendering Machine For Shoe Insole And Midsole
Product Overview

The EVA Foam Sheet Calendering Machine is a heavy-duty industrial machine designed for producing uniform EVA foam sheets used in shoe insoles, midsoles, and cushioning components. Through precision-controlled heated rollers, raw EVA compound is calendered into sheets of consistent thickness, density, and surface finish.

This machine features a four-roll inverted L-type calender configuration, with individually temperature-controlled rolls (up to 200°C) ensuring optimal material flow and surface quality. The gap between rollers is digitally adjustable from 0.5mm to 50mm, accommodating a wide range of product specifications. A motorized nip adjustment system maintains precise gap control under varying loads.

The integrated cooling section rapidly stabilizes the calendered sheet, preventing post-processing shrinkage and ensuring dimensional accuracy. Production speeds of 5-25m/min can be achieved depending on sheet thickness and material formulation. This machine is the backbone of any EVA shoe material production line.

Key Features
  • Four-roll inverted L-type calender configuration
  • Individual roll temperature control up to 200°C
  • Digital gap adjustment 0.5-50mm with ±0.02mm precision
  • Integrated cooling section for dimensional stability
  • Automatic tension control for wrinkle-free output
  • PLC control with production data logging
  • 1 Year warranty

Frequently Asked Questions
Q: What EVA compounds can this machine process?
A: It handles EVA compounds with various VA content (18-40%), including those with foaming agents, crosslinking agents, fillers, and colorants.
Q: How is thickness consistency maintained?
A: Each roll has independent temperature control with ±1°C accuracy. Digital gap sensors provide real-time feedback to the PLC, which adjusts nip pressure to maintain ±0.02mm tolerance.
Q: What surface finishes can be achieved?
A: Glossy, matte, or textured finishes depending on roll surface treatment. Embossing rolls can be installed for patterned surfaces.
Q: What is the typical material waste rate?
A: Under 3% with proper setup. Edge trimming waste can be recycled back into the compound.
Q: How long does it take to change sheet specifications?
A: Changing thickness, temperature, and speed settings takes approximately 15-20 minutes including warm-up/stabilization time.
