Transfer blow molding technique |
摘要 |
Parisons are injection molded using a cooled cavity and a relatively hot core pin to prevent the formation of residual internal stress in or near the inner surface of the parison. The parison is promptly transferred while still hot from the injection mold to a temperature conditioning station to provide a desired temperature distribution and the temperature conditioned parison is highly molecularly biaxially oriented as it is blow molded.
