Part / Runner Separators
LaRos started in business separating parts from runners. Where parts and runners drop together, our finger and roller separators mount to the conveyor discharge and send them to separate containers.
Application
Separating parts from runners
When a mold drops parts and runners together, a separator sorts them so parts go to the box and sprues and runners go to the granulator. The LaRos E-400 and E-540 series finger separators mount at the discharge end of an E-510 or E-525 conveyor and are driven by the conveyor where possible, or self-powered at 115VAC where required.
The separator uses a three-roller design with an extended separation zone. Fingers and thumbs are selected from our standard types to suit the size and shape of your parts and runners, and an agitating option is available for difficult separations.
Send us samples of your parts and runners. We will evaluate them and design the separator around your part and runner discharge requirements.
