Abstract
A split hopper for dispensing granular or powdery materials has a hopper body and a lid. At least the hopper body is formed principally from a castable resin material such as polyurethane. The hopper body is formed from two hopper body sections mating at vertical faces and hinged to one another. Tooling mounts and other features such as clamping lugs can be cast directly into the hopper body sections during the casting process. The lid may be sealed to the top of the hopper body via a ring seal that may seal both radially and axially against the hopper body. A tool holder may be provided beneath the discharge opening of the hopper body for selectively engaging tooling so that the tooling does not fall out of the hopper body when the hopper body is opened.
