Consistent heat for perfect packaging

The requirements for industrial doors vary greatly from project to project. During times of rising global energy prices, many companies increasingly demand thermally highly insulated hall doors. Constantia Teich GmbH in Weinburg, Austria, has installed five Efaflex high-speed doors with extreme thermal insulation for a very special purpose.

"The doors seal our temperature chambers," explains Alexander Kocevar. He is Head of Technical Purchasing at the plant and Category Manager CAPEX for Constantia Flexibles International. Constantia Teich GmbH is an internationally leading provider of flexible packaging materials. High-quality products are manufactured from the main raw materials aluminum, paper, and plastic for the dairy industry, confectionery, food, and pet food industries, as well as international pharmaceutical and cosmetics companies, and supplied worldwide. "The raw tape aluminum, which we roll and process in six of our own rolling mills, is often laminated with materials such as paper and/or plastic before further processing," describes Alexander Kocevar a part of the production process. "This is achieved by bonding them with waxes or adhesives. These substances must cure before further processing. To do this, the finished rolls are transported into large temperature chambers, where they must cure for up to seven days at 60°C." The doors from EFAFLEX close these temperature chambers. "With these extremely high-insulation doors, we limit our energy losses; the heat stays in the chambers, after all, we don't want to heat the entire hall." The company cannot afford a failure of these doors. The heat treatment times would increase significantly, leading to production downtime or complaints in further processing. The doors to the heat chambers are wound in a contactless spiral. It is not primarily about maintaining a perfect surface of the door, but rather about space-saving storage of the door leaf. "Originally, we wanted to open the doors under the ceiling of the chambers. This is not possible inside the chambers due to heat emissions and various lines. Outside, under the hall roof, fire sprinklers are installed, which must also not be covered by the open doors." EFAFLEX was very flexible in planning and handling the project. Another important requirement for the total of eleven high-speed doors was the increased wind class. Alexander Kocevar explains: "We produce almost exclusively for customers with high hygiene requirements. Therefore, our new production hall is operated under positive pressure. This means more air is supplied than extracted. When opening the doors, particles are carried out of the hall, not into it. However, the positive pressure also means that the high-speed doors, which are installed as building enclosures, are constantly exposed to overpressure."

The new production hall of Constantia Teich GmbH, connected to the existing production buildings and the Rolling Mill 2, is used for base finishing with a material width of 1800 mm. The new building has a footprint of 4,700 square meters. An automatic material crane for foil delivery from Rolling Mill 2 and an internal driverless transport system ensure smooth logistics flow. Founded in 1912 by the Teich brothers, Constantia Teich GmbH is located in Weinburg, about 60 kilometers west of Vienna, and today employs around 900 staff. The operation is part of the Constantia Flexibles Group GmbH, which employs over 8,000 people worldwide across more than 50 group companies in more than 20 countries. Continuous training and the health of employees are central to the company's policy. Innovation of their products is the key to success for Constantia Teich GmbH and also serves as a guideline for its partners and suppliers.
