By converting existing equipment this allows mold - ers to reduce their CAPEX of injection equipment (E-Multi Auxiliary Injection Unit vs. 2k Injection Machine) which also helps minimize project risk. Ad - ditionally, a Co-injection solution with E-Multi can be implemented with much faster lead times compared to purchasing a completely new 2k IMM. Mold-Masters Co-injection technol - ogy is compatible with a wide range of materials including Bio-Resins and PCR. Industry-leading co-injection technology Mold-Masters industry-leading Co- injection Technology utilizes a propri - etary nozzle design that allows for two different resins to be combined into a single 3-layer melt stream. By incorpo - rating a high-performance barrier as the core layer in packaging products, co-injection extends shelf life, main - taining freshness and flavour, longer than mono-layer blends. From a pro - cessing perspective, Co-injection in - creases productivity by eliminating the requirement for secondary processes and m i n i m i z i n g scrap. It can also minimize the use of ex - pensive mono- l a y e r b a r - rier materials. Mold-Masters Co-injection Technology is fully customiz - able to create a mo i sture , gas or light barrier for containers of all shapes and sizes without any penal - ty to a molders existing cycle time. Precise pro - cess control enhances molded part properties by adjusting barrier layer placement and thickness to ensure uniform dis - tribution. Light blocking barriers for thinwall packaging Mold-Masters currently offers co- injection hot halves for thin wall pack - aging in any cavitation. The light bar - rier can be virgin or recycled material, both are compatible. Dosing of Black Core can be customized to meet the specific requirements of the molded part (Dosing 5% to 30% dependent on total part weight). Mold-Masters patented process control capabilities allow to maintain complete core bar - rier coverage around the perimeter of non-symmetrical shapes and designs without core breakthrough. Additionally, Mold-Masters Pat - ented Co-injection Process for thin wall offers excellent heat seal bond Mold-Masters is proud to announce that their industry-leading co-injection multi-layer systems are now available for injecting light blocking barrier materials as the core layer packaging applications. Light blocking barriers reduce light transmittance by up to 99.9% to extend product shelf life and preserve freshness and flavor of dairy products.
