Blow molding technology

Fuel tanks with better barrier properties than HOPE alone are fabricated using barrier resin blow molding technology. HOPE is blended with PA/PE barrier resin... 

As mentioned, a suitable technology consists in the fabrication of multilayer bottles. However, such multi-wall bottles have to be produced by the more complex and expensive co-extrusion blow molding technology. Using blends of PEN and HDPE can enhance the objected properties of HDPE bottles, using a simple one-step extrusion blow molding process. 

The multilayer coextrusion blow molding technology can be used for a wide variety of containers made from LCP and other thermoplastics. Figure 11.36 shows a multilayer bottle and tray made from LCP and PET by coextrusion blow molding. Figure 11.37 shows high barrier bottles made with LCP and PET. 

This integral carrying handle was issued in a French patent granted to an Italian company. This patent incorporates a traditional jug handle above the blown portion of an injection blow-molded container, as for example a pitcher. The handle is molded as part of the preform and is undisturbed when the container is blown. A direct extrapolation to stretch blow-molding technology would incorporate the jug handle immediately below the neck finish of an injection-molded preform. It would be necessary to mold such a preform in a split mold that suits itself to production on certain rotary-type injection stretch blow equipment. 

Other applications utilizing blow-molding technology include front-bumper beams, rear-window shelves, and air ducts under instrument panel structure. Blow molding is utilized in these applications due to substantially lower tooling costs over injection molding. 

Haemonetics Bowl Technology. Haemonetics disposable bowl technology has evolved from the original plasma separation chamber. The two principal shapes of bowls are the Latham bowl and the blow-molded bowl (Fig. 4). 

There are also bellows-style collapsible plastic containers such as blow molded bottles (jars) that are foldable. As shown in Figs. 3-16 and 3-17, the technology of foldable...
