[0002] Resin sand refers to molding sand or core sand that uses artificial synthetic resin as a binder for sand particles. Resin sand has high strength after hardening and is particularly suitable for machine modeling. It can produce complex, thin-walled castings. The disadvantage of resin sand is that the binder is expensive and pollutes the air. In order to save the amount of resin, pure round sand particles that have been washed or scrubbed are generally used.

[0003] The feeding funnel for resin sand is a kind of equipment used in the resin sand production line. Its main function is to evenly transport the resin sand from the sand storage tank to the place where it is needed, such as a molding machine or core box.
