E Recommended mold temperature for the usage of a precision leader pin and bushing is 80°C or less because of little clearance between them ( D P.788 ). E Oil groove part might not be colored by heat treatment. Despite differences in appearance, it can be used without any problem. E Please specify each dimension so that L−N−F = 10mm or more.
