PLC-Controlled Vacuum Cleaning Oven for Extrusion Tools — Fully Automatic Polymer Removal

🧰 PLC-Controlled Vacuum Cleaning Oven | Extrusion Tool Maintenance

Product Overview

The PLC-Controlled Vacuum Cleaning Oven is engineered for automated, precise cleaning of extrusion tools, dies, and molds in plastic manufacturing. Using electric heating under vacuum (−0.085 MPa), it gradually removes polymer residues through a three-phase process—melting, pyrolysis, and oxidation—without damaging tool surfaces.

Equipped with PLC temperature control, high thermal efficiency, and automated operation, this system is ideal for plastic extrusion facilities, tooling workshops, and manufacturing plants that require consistent, safe, and efficient tool maintenance.

Technical Specifications

Working Principle

I. Melting Phase
Tools are heated to 320°C under vacuum, melting polymer residues that drain into the collection system.

II. Pyrolysis Phase
Remaining polymer undergoes pyrolysis under vacuum, with gases processed through water scrubbing for clean emission.

III. Oxidation Phase
Final carbon residues are oxidized with controlled air supply, leaving tools completely clean and residue-free.
