Paper Pouring Tube are pressure-formed in molding dies using pulp fibers, high-temperature resistant materials, binders and other raw materials. By designing die configurations, various structures can be produced, including straight pipes, elbows, tees or multi-way pipes, reducers, and other dimensional specifications.Owing to their light weight, ease of cutting, adequate refractoriness, low solid waste generation and other advantages, they are widely used in resin-bonded sand foundry industries, especially in lost foam casting where their application is most extensive.

Application of Paper Pouring Tube in Foundries：

• Casting Name: Automotive Mould

• Molding Process: Lost Foam Full-Mold Casting

• Casting Material: HT250

• Casting Weight: 8 tons

• 
  

• Easy Operation: Light in weight, paper runner pipes are extremely convenient for installation, cutting, handling and transportation, significantly reducing labor intensity for workers.

• Reliable Connection: The pipes adopt socket-type joints, which are resistant to misalignment and ensure tight sealing. This reduces sand erosion risks in castings, effectively minimizes sand inclusions and improves casting quality.

• Environmental Friendliness: Paper runner pipes generate no pollutants during pouring, and their waste can decompose naturally. The matrix carbonizes after pouring with minimal residual waste. Compared with ceramic runners pipes, they help improve the quality of reclaimed sand.
