Nissei ASB Machine Co., Ltd. (Head office: Komoro‐shi, Nagano‐ken, Japan ‐ President: Junichi Miyasaka), a world leading manufacture of machines and molds for injection stretch blow molding of PET and other plastics, wishes to announce the introduction of a new molding process that further enhances the versatility of its line‐up of One‐Step 4‐ Station injection stretch blow molding machinesto provide both ecological and aesthetic container manufacturing solutions.
Previously, multi‐layer preform molding has been used to improve container
performance by inserting a thin layer of a secondary material between two outer body
layers of the preform. ASB’s newly developed Double Layer molding process (patents
pending) enables the container to be molded with an inner and outer layer in the body
section (Image 1) in a variety of thicknesses, configurations, molding order, or resins as
required to provide additional value and flexibility to the standard One‐Step ISBM
process. This method broadens container molding options not only in food safety,
function and design but also encourages increased manufacturing of ecological
containers utilizing recycled PET resin.
To enable this Double Layer molding method, ASB has developed a prototype machine designated the ASB‐12N/DL (Image 2) that issimilar in size to its existing small‐scale ASB‐ 12N/10 4‐station injection stretch blow molding machine. This newly developed machine consists of five stations, with a second injection mold occupying the additional station being supplied by its own injection unit (Image 3). The ASB Series One‐Step molding process is already well known for its extreme versatility in molding high quality container in a vast range of molding resins – now with the addition of the Double Layer molding process, the possibilities to it is possible dramatically enhance either visual or physical properties using different materials for inner or outer layers.
