Roto Molding of Poly-Vinyl Seat Bellows for the Trucking Industry
A client specializing in high-end air ride seats for the Trucking Industry was in need of a flexible seat bellow to encompass the bottom of their seating systems. After consulting Rhino, Inc., it was determined a poly-vinyl compound would best meet the functional specification of the part while still delivering the performance characteristics the client was seeking.. The process involved the manufacturing of a CNC machined aluminum mold that would mold the part in such a way that the accordion type flexibility would be sustained. Post mold finishing of the part included flash trimming and cutouts for attachment and assembly, requiring no secondary operations from the client.
The part measured 19.25 inches long, 9.94 inches high, and 17 inches wide. It weighed 4.5 pounds at completion.
Special features included bellows rib design, allowing for easy shape fluctuation for the air shock movement. Upon completion, the product was thoroughly inspected to ensure consistent material dispersion throughout the ribs and a consistent material finish.
