■ Precautions for use When assembling the sprue bushing guide and the sprue bushing, adjust the end faces of both of the products and then fix them in place. The angle tolerance of the bore taper of the sprue bushing guide is controlled within the range of + 5´ to + 20´, however matching with separately manufactured sprue bushing is not done, so be sure to adjust the products before using.

＊ In the case of the T dimension 20 locating ring, the taper interferes with the bolt counterbore part. E Calculation of α value α= P + 2Xtan A 2 °
• By using this product, tapering to the runner stripper plate will be unnecessary. It will only be necessary to machine round holes, so the machining will become easy.
