Three Links Sprue Runner Pipe Fittings

Three links sprue runner pipe fittings is made of pulp and high-temperature resistant fiber composite material.It is non-burning, lightweight and degradable.
It realizes the reuse of resources and reduces environmental pollution. It is supported by the national environmental protection policy. The paper sprue runner casting pipe has various specifications such as straight casting pipe, elbow casting pipe, equal-diameter tee, variable-diameter tee, and variable-diameter straight-through.


Product Features:

1. The paper pipe fittings have good toughness, easy to cut, easy to install, easy to connect with foam plastic runners.

2. Good high-temperature strength, high refractoriness, and strong anti-scour ability. The paper sprue runner casting tube adopts a socket connection, and the filter mesh is used together to filter the slap and impurities after pouring the molten metal into the runner, effectively preventing and eliminating the occurrence of slag inclusion defects.

3. Does not have any effect on the molten metal, maintains the original performance of the molten metal, and has no carburization problem for the casting. Use paper sprue tube, sprue cup and sprue superheat zone, sprue and sprue joint, no foam or paint layer, will not cause sand washing, sand inclusion, and sand into the casting White spot (dot) defects. The paper sprue casting tube has high refractoriness, reducing and avoiding the formation of carbon deposits and wrinkle defects.

4. Compared with the foam coated sprue, the paper uses a hollow hollow sprue tube, and the initial casting does not burn the foam material, which reduces the incidence of the reverse reaction caused by the pyrolysis and gasification reaction of the foam material during pouring. Effectively reduce the heat loss of the runner metal liquid, and prevent the occurrence of problems such as sudden and small, broken flow during the casting process due to back spray.

5. After pouring with a paper sprue runner, there is little hard solid waste, which is easy to peel off after high temperatures.

Application of Pipe Fittings:

Through the application of the lost foam and solid casting, the paper sprue casting tube does not produce an endothermic reaction or gasification and cooling of the foaming runner at the beginning of the molten metal casting like the casting ceramic tube. Because of its good thermal insulation performance, the paper sprue runner casting tube reduces the heat transfer of the molten metal to the pipe wall, so that keeping the molten metal without cooling is equivalent to increasing the temperature at which the molten metal enters the mold, and the temperature of the molten metal is relatively stable, prompting the molten metal. The filling is fast and smooth. The molten metal has sufficient time to replenish, which is beneficial to equalization and solidification.
