METHOD FOR PRODUCING A PREFORM

Injection molded preform and manufacture thereof

An injection molded thermoplastic preform for blow moulding to form a container, the preform base of a central part having a first, downwardly and radially inwardly tapering portion therebetween which increases in thickness from a radially outer end of the first tapering portion adjacent to the hollow transition portion to a radially inner end of the first tapering portion adjacent to the gate part and the middle part opposite the gate part can allow the injected resin to be urged back through the gate at the end of the injection moulding cycle at a lower fluid pressure in the vicinity of the gate which is associated with high resin temperatures. The technical effect achieved by the first tapering portion is that crystallinity in the gate area is minimized or eliminated, which avoids or minimizes partial blocking of the gate which would otherwise restrict the injected resin from being urged back through the gate at the end of the injection moulding cycle.

Plastic article consisting of several materials as well as method for the manufacture thereof

A hollow plastic article consisting of several materials has a wall in which the materials are joined together via their contact surface. At the closed lower end (10b) of the plastic article (10) there are sprues (51, 52, 53). Because the lower end (10b) is amorphous inside the wall thickness x in spite of the sprues, a homogeneous structure of the plastic article is achieved. This can be realized by injection moulding in several steps in mould cavities in which case the injection preferably is carried out with open shut-off nozzle, or when the first material is injected a long sprue stalk is produced in order to keep the closed lower end (10b) amorphous, or to keep any crystalline areas outside the wall thickness (Fig. 2).

Preforms for flair applications

A preform can be made from two different materials that do not bond together by a bi-injection process, using the same mold. First an outer preform can be fashioned, then an inner preform molded through a center hole in the bottom of the outer preform, and the preforms connected. Inner/outer preform materials can be different, e.g., PET/polyolefin or polyamide, or same, e.g., PET/PET. To prevent mutual bonding during molding of the second, a non-stick coating can be sprayed on a surface portion of the first preform prior to molding the second. Manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the preform first molded.
