Milacron Co-injection multi-layer technology is designed to meet the plastic industry’s need for a successful high barrier technology in a robust multi-layer plastic preform, closure or container that can be delivered with the same high-volume production efficiency and cycle time as a monolayer plastic preform, closure or container without barriers. Milacron Co-injection technology addresses key concerns in the industry, including economical use of barrier materials (as low as 0.5%), preforms with customizable barrier properties, and uniform distribution (lengthwise and around the leading edge of barrier).
Milacron Co-injection uses a proprietary, simultaneous co-injection process with every system. This simple, fast process allows the cavity to be filled in exactly the same amount of time as a basic monolayer injection molding process. The “heart” of each system is the Milacron Co-injection melt delivery system whose function is to force melted resin into a mold cavity. The melt delivery system has separate streams (flow channels) for skin (the inner and outer layers) and core (the middle barrier layer) materials.
Milacron Co-injection’s patented, proprietary co-injection nozzle designs allow two different resins to be combined in a single 3-layer melt stream. With no moving parts, the two flow streams are joined at each patented co-injection nozzle resulting in a single, combined 3-layer flow stream through each gate, into the mold cavities. The result is total control and ability for customization of the core layer placement and thickness.
