In the chilled process of casting, increase of organic matters in molding sand creates massive gas, thus flames / blowholes happen easily. There is a need of smooth gas exhaust channel to prevent, and avoid casting scrap. Ventilation ropes solve this problem effectively.
Choose proper ventilation rope as per the core size. The rope is covered in the core, with one-end broadening out.
Effective gas exhausting.
Prevents blowhole defects and improves casting output.
High efficiency, particularly in complex, bigger sand molds.
Easy removal, and no pollution.
