Improved from the classic single arch shape, the vase design with a 60° bottom cone angle prevents powder collection, piling, or blockage inside the bellows during operation.
Silicone Weighing Bellows Asymmetrical Conical White are created for industries with rigorous standards and strict production parameters. Made out of our compression-molded translucent 60° Shore A silicone, this decoupling compensator relieves downstream stress by preventing force transfer. As a result, manufacturers can achieve accurate weighing results and maintain product purity.
SIL WB AC W is ideal for highly regulated applications with strict product purity, weight sensitivity, and hygiene requirement. It is safe for use in environments with explosion risk.
