Apparatus for feeding synthetic material to a mould

摘要

This invention relates to apparatus for feeding synthetic material to a mould and includes a mixing chamber and a sprue runner leading from the mixing chamber to the mould. The sprue runner is branched so that the material fed from the mixing chamber is divided into at least two equal parts, the branches of the sprue runner leading to a common section in which the divided parts of the material are recombined prior to feeding to the mould. The branches of the sprue runner are also provided with constrictions.
