A retrofit starts with space, handover and controls.
Adding a cap feeder to an existing capping machine can reduce manual loading and improve consistency, but the retrofit must work with the machine already on site.
The key checks are available footprint, discharge height, guarding, capper handover, electrical signals and how the operator currently loads caps. Photos and dimensions are very useful at the first stage.
A retrofit may use a bowl feeder, hopper, elevator, sorter, chute or a combined system depending on the closure and the current capper design.
