Filter for injection molding machine

摘要

An injection molding machine includes a nozzle for supplying a melted resin into a mold. In the nozzle, there is a filter for removing foreign materials mixed in the melted resin. The filter has a cylindrically-shaped filter body. In the filter body, many small holes are formed. By supplying the melted resin into the mold, the melted resin passes through the small holes into outside of the filter body. In cleaning the filter, the melted resin flows from the outside into the inside. The small holes each are smaller on the inside than the outside.
