METHOD AND APPARATUS FOR PRODUCING HOLLOW ARTICLE |
摘要 |
<p>Process for making transparent hollow bodies of terephthalate of polyethyleneglycol in which a preform is made, the preform is cooled rapidly to a temperature at least equal to the crystallization temperature, and is then rapidly expanded to obtain bi-orientation and solidification prior to substantial crystallization of the material. The preform can also be axially stretched during the operation. The apparatus for preforming the process includes a rotatable turret with mandrels, which operates to slightly expand the material on a mandrel.</p> |
