■ Feature The thickness of the metal sheet of this product that is lightly press–fit for eliminating stringing can be selected. The metal sheet is thinner than that of a normal type product, and also the height direction is set on the short side. ■ Expected effectiveness Minimizes reduction of the injection pressure Reduction of frequency of occurrence of sticking of the sprue to the metal sheet ■ Guide to the selection of metal sheet (for reference) It is recommended that you select the sheet thickness taking into consideration the size of the molding machine, resin used, etc. Y0.5 ⇒ 15t/30t class molding machine Y0.6 ⇒ Molding machine of 50t or greater class
