Description
The sprue bush is a part that allows plastic material to be injected from the nozzle into the interior of the mold. The tapy A sprue bushing is fixed to the mold with 2 bolts to prevent it from falling off due to the injection pressure. In order to prevent leakage of plastic material, the feed port is generally designed in an arc shape.
