Plastic Injection Molding for Closures

Montebello Packaging Plastic Caps ClosuresMontebello Packaging has extensive experience in closure making going back 30 years. They manufacture a variety of closures for both aluminum and laminate tubes that they produce, and also sell closures for outside companies. Montebello utilizes hydraulic and all-electric Injection Molding machines, ranging from 28 up to 400 ton capacity. In order to increase efficiency and cost effectiveness, they use new Sumitomo injection molding machines which have clamp capacities up to 230 tons.

The Sumitomo machines provide higher torque, faster speeds, higher injection pressures and increased precision and application flexibility.

What is injection molding without molds? They are meticulous in taking care of their molds, relying on Hot Runner Molds to make operations more efficient, due to the elimination of runner scrap.

All of these factors plus their tube manufacturing division’s high standards, creates closures of very high quality.

Closures are available in both standard and custom designs, and are available in low and high density polyethylene and polypropylene. They also use resin combinations that are the result of their own experimentation to get higher quality and productivity.
