In industries such as polymer production, nonwoven textiles, plastics extrusion, and filtration manufacturing, equipment contamination is one of the biggest causes of production downtime and quality defects. Melt residue buildup in spinnerets, filters, die heads, and mould tools not only reduces flow efficiency but also directly impacts product quality and output.
To address this global industry challenge, manufacturers are now shifting from traditional manual cleaning and chemical cleaning to a more advanced solution:
The Vacuum Pyrolysis Cleaning Furnace
This blog explains what it is, how it works, why global factories prefer it, and how it can improve your production efficiency.
π₯ What Is a Vacuum Pyrolysis Cleaning Furnace?
A vacuum pyrolysis cleaning furnace is a high-precision industrial cleaning system designed to remove polymer, carbon, and organic residues from:
- Nonwoven spinnerets
- Meltblown spinnerets
- Extrusion die heads
- Melt filters
- Breaker plates
- Gear pump components
- Mould heads & fine nozzles
It uses electric heating + vacuum pyrolysis + controlled oxidation, ensuring that even micro-level residues are removed without damaging sensitive metal surfaces.
Unlike chemical baths or fluidized beds, this method is clean, safe, and fully automated.
βοΈ How a Vacuum Pyrolysis Cleaning Furnace Works (Simple Explanation)
The cleaning process occurs in three automated phases:
1οΈβ£ Melting Phase (Around 320Β°C)
Polymer residues melt under vacuum and flow into the collection tray.
β Prevents overheating
β Removes 70β80% of contaminants
2οΈβ£ Pyrolysis Phase (β0.085 MPa Vacuum)
Remaining polymers vaporize safely under low pressure.
β No metal oxidation
β Clean breakdown of polymer chains
3οΈβ£ Controlled Oxidation Phase
A minimal amount of air oxidizes carbon residues.
β Leaves surfaces bright, smooth, and residue-free
The entire cycle typically takes 3β6 hours, depending on contamination level.
π Why Manufacturers Are Switching to Vacuum Pyrolysis Cleaning Furnaces
1οΈβ£ Zero Damage to Precision Components
Spinnerets and die heads contain micron-level holes.
Chemical cleaning and mechanical scraping often deform or scratch them.
Vacuum pyrolysis is stress-free and contact-free.
2οΈβ£ Cleaner Than Fluidized Bed or Chemical Cleaning
No abrasive media
No acid fumes
No chemical waste
This is the most environmentally friendly cleaning method available today.
3οΈβ£ Fully Automatic β No Skilled Labor Needed
Workers only load the parts and press START.
The PLC system handles all phases:
- Heating
- Vacuum control
- Pyrolysis
- Oxidation
- Cooling
Perfect for factories struggling with labor shortage.
4οΈβ£ Saves Energy & Reduces Maintenance Costs
With β₯98% thermal efficiency, the system requires minimal energy to operate.
Components last longer because there is no mechanical wear.
π Which Industries Benefit the Most?
A vacuum pyrolysis cleaning furnace is essential for:
β Nonwoven & Meltblown Production (PPE, diapers, filtration media)
β Plastics Extrusion Plants
β Chemical Fiber Manufacturing
β Polymer & Resin Production Lines
β Injection Molding & Gear Pump Maintenance
β Laboratory R&D for Polymer Processing
If your factory works with PET, PP, PA, PE, TPU, EVA, ABS, this cleaning method gives you the highest ROI.
