A new quick-mold-change device from SIG Corpoplast, Hillsborough, N.J., speeds changeovers of stretch-blown PET bottles.

A new quick-mold-change device from SIG Corpoplast, Hillsborough, N.J., speeds changeovers of stretch-blown PET bottles. Instead of unbolting several screws, the Speed-Loc system uses a 10-in. lever integrated into the blowing station to unlock the mold base, inner shells, and stretch rod. Mold-change time is said to be cut almost 50%. The mold base and inner shells are released with the lever in a single step. The lever can be used to easily adjust the stretch rod without removing it for bottles with different lengths or base geometry. Speed-Loc can be purchased as an option or retrofit for SIG's Blomax series 3 machines.
