🔬 Working Principle

I. Melting Phase (Gentle Start)

Spinnerets and filters are gradually heated under vacuum to 320 °C, melting and draining most of the polymer residues before decomposition begins.

II. Pyrolysis Phase (Core Removal)

Remaining polymers are vaporized and chemically decomposed under a −0.085 MPa vacuum. This low-oxygen environment prevents oxidation and ensures clean vapor exhaust via the dual-stage scrubber system.

III. Controlled Oxidation Phase (Final Polish)

A precise airflow is introduced to oxidize residual carbon into ash, leaving a bright, residue-free surface ready for production use.
