Mini Runner System Body Features

The Mini Runner System body contains a manifold that comes equipped with a built-in heater and a sprue bush, designed to fit in any required amount of injection openings at their necessary positions.

Compact and streamline in design, it requires only one accessory, i.e. a Sprue Bush. It can connect to the injection nozzle of the mold, yet hold rigid in place with an easy mounting that is suitable for both new and modified old molds.

It is simple to install the mini runner into a mold. As shown be the figure, the manifold only needs to be fixed in the mold's top clamp plate with spacer blocks added to keep it rigid and warm.
