The advantages of paper runner pipe used in resin sand casting were good operating performance, high temperature metal liquid erosion resistance, superior thermal shock resistance. High strength at normal temperature is not easy to damage, less residue after pouring, easy to consume; No leakage, no sticking sand, effective reduction of casting scrap rate. Paper runner pipe not only improves casting quality, but also selects renewable resources and reduces environmental pollution. It is a green and environment-friendly innovative runner pipe for casting process.
