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 A center hole may be left on one or both ends. E Temper color (heat treatment color) may not be applied to the tip. Despite differences in appearance, it can be used without any problem.
