SIPA reveals SFR EVO3 range improvements

29 May 2013


Plastics packaging specialist SIPA has developed new versions of its SFR EVO3 model range of rotary stretch-blow moulding machines, which are now available in versions with 6, 8, 12 and 16 cavities.

According to the Italy-based company, a new 10-cavity platform and larger units, with 20 and 24 cavities, will debut later this year.

“SIPA’s approach is to put increasing emphasis on improvements that bring savings and added value to our customers’ investments,” says the company’s blowmoulding systems sales director Pietro Marcati.

“The SFR EVO3 shows that it is still possible to make significant improvements in output rates, flexibility, efficiency, and total cost of ownership (TCO).”

Special features include new designs in the clamp unit and in the cams that help the SFR EVO3 achieve a maximum output rate of 2250 bottles per hour per cavity, while a new blowing valve block is said to be more compact than before, with 35% less dead air volume.

The new system is also said to give a “massive reduction in air consumption”, particularly with smaller bottles through a mechanical compensation in the blowing process.

“In traditional pneumatic compensation, the total stroke is made with high pressure blowing air, but in SIPA’s new mechanical system, high pressure blowing air is used only on the final fraction of a millimeter,” the company says.

Technological improvements in the ovens are also said to reduce electrical consumption by up to 40%, while keeping process conditions stable, thanks to the use of new lamps and special materials and coatings for the reflectors.

The new SFR EVO3 design includes a new standard mould changeover system said to be quick and easy to use and, with the cooling circuit built into the cavity, only a simple cavity change is required to switch from production of one type of container to another, while the shell holders remain in place.
