A new "Double Gate" system prevents core-pin deflection when molding long, thin parts such as pipettes. This approach from Schottli AG Mould Technology in Switzerland (represented here by Schottli USA, Peachtree, Ga.) injects material on two sides of a core pin. Dual gates add 10% to 20% to mold size. In addition, Schottli now offers a line of soft-drink closure molds with up to 96 cavities. The molds produce caps with a 28-mm thread for carbonated soft drinks or with 25- to 39-mm threads for non-carbonated drinks.
