Improved injection mold dwell cycle |
| abstract |
Preparation of oriented hollow articles of moldable organic plastic material, by injection molding a parison (16) tempering it in a tempering mold (22) to obtain uniform orientation conditions and orienting and expanding the tempered parison (16) to obtain the hollow article (40). The preparation further comprises: rapidly cooling the parison at the injection mold (10) until its inside temperature near the middle between its outer skins, drops below that which corresponds to the highest rate of crystallization for the given plastic material; rapidly removing the parison (16) from the injection mold (10) even while the parison (16) has an unequal temperature distribution and before the parison attains an average temperature suitable for orientation; and rapidly transferring the parison to a holding mold (10') between the injection mold (10) and the tempering mold (22) for continuing to alter the heat content of the parison (16) and thereby to attain an average temperature suitable for orientation, thus freeing the injection mold (10) for the formation of a next parison (16). |
