PTi offers extruder motor option

Issue: July 2018

Processing Technologies International (PTi) during NPE2018 highlighted its new tuck-under motor option on its Super-G HighSpeed sheet extruders.

The new option reduces the extruder’s footprint by 33 percent and results in major production gains.   With it, users can achieve the highest outputs on a machine-footprint basis in the industry, company President Dana Hanson said.

“Our high-speed extruder technology sets a new industry standard in terms of output per unit area thanks to the tuck-under option,” Matt Banach, senior VP of sales and marketing, said in a written statement. “Our Super-G technology has set the standard for high-density manufacturing, now delivering unprecedented output per square foot.”

Super-G HighSpeed extruders are used to process PP and high-impact PS for the packaging market.

In addition to its tuck-under motor, the Super-G SGHS3000-36D model features a vertical U configuration. Compared with the original model, which was 12.7 feet long, it is 17.5 feet long.

Other Super-G HighSpeed extruder models are available with the tuck-under option and offer comparable footprint reductions.

The Super-G SGHS3000-36D is equipped with a 500-horsepower (hp) motor and runs at a maximum speed of 1,000 rpm, while the Super-G SGHS3000-42D has a 600-hp motor and runs at a maximum speed of 1,200 rpm. For PP, the 36D can process about 3,000 pounds per hour.

PTi’s high-speed extruders feature carbide-lined barrels and Colmonoy hard-faced feed screws compared with case-hardened screws featured on competitive models, the company said.

The Super-G HighSpeed extruders also include an oversized feed section that promotes higher regrind feed rates of up to 70 percent. Other key features include the ability to remove the feed screw through the back of the unit, an easy-cleanout vent chamber and linear bearing barrel glide support. The patented barrel glide support technology is part of the company’s M-ATEX support system for complex coextrusion applications. M-ATEX allows for the unrestricted thermal expansion of numerous components, including the barrel and die, which is critical for avoiding vibration and thermal stresses.

For safety, air-cooled heater and blower assemblies limit the exterior temperature. Maximum external temperatures on the extruder can reach about 110 degrees Fahrenheit, compared with as much as 500 degrees Fahrenheit for some competing models, the company said.

At NPE2018, the company also featured information about the G-series QuadPlus configuration, in which G-series extruders can be configured to produce multilayer sheet.
