Abstract
A process and apparatus for forming a leak proof body and cap. The process including the steps of defining a mold cavity between a first mold part and a second mold part, injecting a molten material into the mold cavity thereby forming from the molten material a body and cap, and retracting the first mold part from the second mold part to separate the first mold part from the body and cap. Thereafter, engaging at least the body with a robotic arm and moving the body with the robotic arm into a capping device while the body and cap are at a temperature at which the material is not fully set. The body is then sealed by moving the cap into engagement with the body to form a leak proof seal.
