Application: In the chilled casting process, the increase of organic matters in molding sand brings massive gas in the sand mould, thus blowholes or flames happen easily. A smooth gas exhaust channel is needed to prevent this to avoid castings scrap. Ventilation ropes effectively solve the above problem.
Use: Select the proper ventilation rope in accordance with the core size. The rope(s) is (are) covered in the core, with one end extending out through the core print.
Features: 1. Obvious gas exhausting effect. 2. Effectively prevent blowhole defects, improve casting yield. 3. High efficiency, especially in bigger and more complex sand molds. 4. Easily removed, no pollution to the reclaimed sand.
