Solutions for Restoring Permeability in PM-35 Ventilated Breathable Steel

Over time, the permeability of PM-35 Ventilated Breathable Steel may degrade due to clogging or contamination. Below are professional solutions to restore its performance:

Plastic Residue or Tar Clogging: If micro-pores are blocked by plastic debris or tar, apply a suitable plastic-dissolving solvent. Allow it to sit for one hour, then use high-pressure air to clear the pores and verify permeability.
Oil Contamination from Mold Additives or Release Agents: Clean the surface with acetone or a similar solvent to remove oil-based contaminants. Follow up with high-pressure air to test the restored permeability.
Advanced Restoration with Soft Machining: If the above methods fail, employ soft machining techniques such as wire EDM or laser processing to repair the surface. After machining, clean the material with acetone and ensure it is completely dry before reuse.
Addressing Flow Marks or Stains: Flow marks and stains are often caused by factors such as inadequate venting, improper cold slug well design, gate geometry, mold temperature, or material properties. While PM-35 effectively resolves venting issues, other factors require separate analysis and adjustments to the mold design or process parameters.
