Compression Molded PET Preforms Challenge Injection Molding

摘要

Lower cost, higher quality and productivity, and the potential for lightweighting beyond anything yet seen are benefits claimed for a new continuous compression molding process for making PET bottle preforms. The Preform Advance Molding (PAM) process was introduced at the recent K 2007 show in Dusseldorf by Sacmi Imola S.C. of Italy. It's still too early for PAM to offer a serious challenge to injection molding. By next month, Sacmi plans to have built two machines for in-house development use and hopes to commercialize the system in the second half of this year.
