Method for blow molding hollow articles

In a blow molding process, a fused thermoplastic polymer parison is interposed between a pair of split molds. The split molds are closed around the parison to seal the ends. A small diameter hollow needle is inserted through one of the split molds and fluid is blown into the parison forming a balloon. After the balloon begins to form, a large diameter hollow needle is inserted while internal pressure is applied to the parison via the small diameter hollow needle, and a large amount of fluid is blown in. This process is highly productive and reduces the conventional blow molding cycle by 60 percent due to the rapid cooling of the hollow article.

Needle blow nozzle and an air cooling process

A blow nozzle 1 comprises a tubular body 4 with a needle 5 at its end, the tip 9 of the needle being located on the central axis of the tubular body. The needle 5 is formed with an umbrella-like shape, and has a plurality of nozzles 20 for blowing air into a parison in a blow moulding apparatus. The umbrella-like shape is provided by a number of elongate cutting areas 10 formed in an outer peripheral surface of the needle portion 5, which areas 10 have sloped edges 11 extending from the needle tip 9 at an acute angle. The shape of this needle reduces the resistance against insertion into the parison, and allows a large diameter blow nozzle to be used. Air can be supplied through an air cooling apparatus (figures 8 and 9) to rapidly cool the parison, whereby the moulding cycle time can be reduced. This is helped by circulating the cooled air through a circulating jig (200, figure 8), prior to injecting the needle 7 into the parison. Also disclosed and claimed is a driving mechanism for the ...

Apparatus for forming multiaxially oriented containers

Multiaxially oriented containers are formed from an extruded, molecularly orientable thermoplastic parison having a programmed wall thickness. The parison while at extrusion temperature is sealed at one end and expanded incrementally in a conditioning mold into the shape of a preform which is allowed to set therein for a brief time period in order to develop an outer skin at reduced temperature. The full wall of the variable thickness preform is then reduced in temperature to within the orientation temperature range and the preform then stretched longitudinally and expanded radially in a finishing mold to develop axial and radial orientation while forming the container. Since the thicker portion(s) of the programmed parison do not cool as much in the conditioning mold as do the thinner portion(s) they consequently subsequently stretch to a greater extent, and this phenomenom must be compensated for in the initial programming step. The container finish is preferably formed in the conditioning ...
