About Project

A company needed a batch of custom hoppers which had to be durable, flexible, and easy to clean. The hopper also had to have a bellows structure, so it could expand and contract. The company also wanted a translucent frosted white appearance.

The company contacted FacFox, a leading provider of urethane casting services, to create the hopper. FacFox used a 3D printed master model to create a silicone rubber mold. Then, they injected a polyurethane resin with silicone rubber additives into the mold. The resin had a Shore A hardness of 30, which gave the hopper a soft and elastic feel. The resin also had a translucent frosted white color, which gave the hoppers a smooth and elegant look.

The urethane cast silicone rubber hoppers were ready in just a few days, thanks to FacFox’s fast and efficient process. The hopper had a parting line and some overflow material that needed to be trimmed, but this was easily done by FacFox’s skilled technicians. The company was very satisfied with the quality and appearance of the hoppers.
