Italian blow molding equipment maker Sipa SpA (Booth S18075) is launching a two-cavity version of its SFL linear blowing molding machine at NPE2009.
The company, part of the Zoppas Industries group, first introduced its SFL machines in four- and six-cavity versions in 2006 and has since delivered more than 200 models to customers in nearly 50 countries.
The machine at the show in Chicago is the first two-cavity version of the design, said Sipa marketing manager Roberta Gualtieri.
Demonstrating the production of disposable PET water-cooler bottles, the new machine can make containers as large as 2 gallons (7.8 liters).
The company also is showing a six-cavity version of the SFL blow molding machine, which will be delivered to the Plain City, Ohio, plant of GK Packaging Inc. immediately after NPE ends.
GK Packaging will use the machine to produce special oval containers using the integrated differential heating system, Gualtieri said.
SFL-series machines provide high productivity (up to 1,800 bottles an hour per cavity) and low energy consumption, according to the company. The fully electric machines can be used to produce standard, custom and handled bottles, as well as hot-fill designs.
Economical operation is ensured, Sipa said, through the use of Sipa's ARS blowing air-recovery system.
The third machine at the booth in Chicago is a rotary machine from Sipa's SFR Evo line, which is demonstrating production of a 38-millimeter, half-liter hot-fill bottle weighing 24 grams (0.84 ounce).
The machine uses the company's crocodile mold-opening sytem.
This special mold-opening concept enables the blowing machine to be much smaller, Gualtieri said.
The SFR Evo machines are also equipped with electrical mold heating, which the company claims enables it to cycle mold tempertures very quickly.
Sipa is also showing its PET flask system for production of beer kegs on its stand. This system, which is already on the market in Europe, uses a collapsible film liner inside a pressurized PET flask to protect contents from oxygen.
The entire flask is enclosed in a cardboard pack for easier handling.
Gualtieri sees the weight-saving potential of the packaging concept appealing to U.S. beer producers.
It's just a matter of finding a customer, she said.
North America is a key market for Sipa, according to Gualtieri. The company's sales, service and technical support activities are run out of its Sipa North America Inc. operation, headquartered in Atlanta.
The company is currently expanding its support for U.S. customers with the addition of a new Mexican mold manufacturing plant to its PET Molds & Components Inc. (PMCI) division. The plant, in San Luis Potosí, Mexico, is scheduled to begin production by the end of the year, officials said.
