Abstract
An improved molding process for molding weighing funnels. The molding process involves forming one or more mold cavities wherein each mold cavity comprises an upper cavity portion in an upper mold section and a lower cavity portion in a lower mold section. A two piece core comprising an upper core and lower core are positioned in close proximity to one another. The lower molding section is moved upward to place it in close proximity to the upper molding section to form a mold cavity while the lower core is simultaneously moved into the mold cavity into close proximity with the upper core. Plastic is injected into the mold cavity using hot runner technology to form a weighing funnel. After the weighing funnel is formed, the lower molding section is moved downward while the lower core is simultaneously retracted from the mold cavity. A robotic arm is used to remove finished product from the mold.
