Abstract
A method and apparatus are disclosed for forming thermoplastic articles in which preforms are injection molded interiorly of mold cavities around substantially cylindrical core pins on a rotatable turret. The turret is then indexed to displace the core pins to a second position and the preforms are retained on the core pins during indexing and thereafter to cool the preforms to a self sustaining condition. To enhance cooling, the preforms may be engaged by temperature conditioning molds while on the core pins. After adequate cooling, the preforms are removed from the core pins and positioned on carrier sleeves. The preforms are then thermally conditioned on the carrier sleeves to a predetermined temperature, following which they are blow molded in blow mold cavities.
