Twin Sheet Thermoforming Key to Design

HOWES CAVE, NY (October 29, 2010) - Kintz Plastics, Inc., a leading heavy gauge thermoformer, has been selected by Optiwind of Torrington, Connecticut, to produce covers for the vertical surfaces on Optiwind's innovative wind turbines. The Optiwind turbines are designed to harness wind power for mid-size commercial customers including schools, colleges, hotels, retailers, farms and municipalities. Unlike traditional wind turbines, the Optiwind turbines are compact, quieter, and will be built right on the site of the energy user.

Optiwind turbines stand just under 200 feet tall and require a cover that is strong enough to withstand wind and weather forces, but lightweight and durable. Twin sheet thermoforming, a manufacturing process that produces double-walled parts or components, provides the necessary strength, but is lightweight. By joining two thin sheets of plastic into one seamless unit, the part becomes stronger than a single reinforced sheet and will still be lighter and less expensive than alternative materials.

"Twin sheet thermoforming was key to the design of the wind turbine," said David Hurwitt, Optiwind Vice President of Marketing. "The cover that Kintz is producing is strong, lightweight and cost effective."

In addition to the strength requirement, the size of the part (66 inches by 105 inches) created a production challenge. This is the largest twin-sheet thermoformed part Kintz has produced to date.

"There aren't many thermoformers capable of producing a part this complicated and this large," stated Wynn Kintz, CEO of Kintz Plastics. "Our team worked with Optiwind to hone the technical specifications for this innovative product and create a part that will become an integral component of the wind turbine."

Optiwind's first wind turbine was built on a farm in Torrington in 2010. The company plans to launch commercially in 2011.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
