Pet Preforms
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 preforms. The Preform Advance Molding 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.While potentially fomenting a battle between injection and compression molding for the preform business, SACMI has a foot in both camps. Its PAM system is an outgrowth of its established machinery for continuous compression molding of beverage-bottle caps and other closures, which now can turn out up to 100,000 caps/hr. On the other hand, Sacmi recently established a PET division to offer complete preform manufacturing systems encompassing injection presses from its Negri Bossi subsidiary (which now incorporates two other Italian press makers with preform experience, Oima and BM Biraghi), as well as Negri Bossi robots and Sacmi’s preform molds and vision inspection systems.
