Custom Manufactured Plastic Jug from a Single Cavity Blow Mold, used in Liquid Storage Applications

The image to the left displays a typical jug made from a single cavity blow mold used to produce plastic jugs. The mold has been custom manufactured by Colonial Machine for the liquid storage industry.  To begin this project, we first used our vertical CNC milling machinery to rough machine the mold's impression area.  We also used our CNC milling equipment to drill waterlines, perform all necessary counter boring and tapping operations, and finish all impression surfaces per client specficiations.  Our advanced techology was used to burn any sharp corners - meeting percise .001" tolerances.

Formed from 7000 series aluminum, the completed mold measured 6" x 9" x 12". The part also featured steel striker plates and beryllium copper pinch plates.  After manufacturing was complete, we preformed glass bead blasting.  Satisfying our client's requirements for quality and design, Colonial Machine produced 60 units of this plastic jug single cavity blow mold for the liquid storage industry.
