Vacuum Cleaning Furnace for the Film Industry — Fully Automatic Polymer Removal System

🎬 Vacuum Cleaning Furnace for the Film Industry | Automated Polymer Removal System

Product Overview

The Vacuum Cleaning Furnace for the Film Industry utilizes vacuum pyrolysis and oxidation technology to completely remove polymer buildup from die heads, rollers, and filters used in film extrusion and coating lines.

By precisely controlling temperature (up to 450°C) and vacuum levels (−0.085 MPa), it ensures safe, residue-free cleaning without damaging parts. The fully automated cleaning cycle minimizes manual labor, reduces downtime, and extends equipment lifespan — essential for maintaining consistent film thickness, clarity, and quality.

Technical Specifications

Working Principle

I. Melting Phase
Components are slowly heated to 320°C, melting polymer residues that flow into the collection base.

II. Pyrolysis Phase
Remaining polymers undergo thermal decomposition under vacuum, with generated gases processed through a water-based scrubber for clean exhaust and condensate removal.

III. Oxidation Phase
Residual carbon and ash are oxidized under limited air supply, leaving the parts bright, clean, and ready for production reuse.
