Netstal launches 2 new PET systems

At a world premiere, the Swiss machine manufacturer will present the new PET-LINE 2400 for the first time at the drinktec 2013 in Munich (September 16 to 20, 2013, Hall B3, Booth 339). Also, its new PET-LINE 4000 will be available for individual inspection at works in N?fels .

At the drinktec Netstal will demonstrate the manufacture of a 0.5 l lightweight preform on the PET-LINE 2400. The Swiss-based company Otto Hofstetter is collaborating as a partner for the mold. The molded part is produced in a total cycle time of just 5.4 seconds using a 72-cavity mold. The Italian-based company Piovan is responsible for the material processing and the air dryer. Devices from the Swiss company  ef-cooling will take care of the cooling.

"We are currently experiencing increasing customer demand for high-quality beverage bottles and caps. Customers are increasingly appreciating the fact that we are able to develop the right system solution with the right system for specific applications. Thanks to our high level of expertise and power of innovation, we can guarantee maximum cost effectiveness and the most efficient production for our customers," explains Markus DalPian, Head of Business Unit PET.

With the new PET-LINE 2400 as well as the new PET-LINE 4000, Netstal is responding to the global trends for continuous improvement of production and energy efficiency. Great emphasis is also placed on material, and hence, cost savings.

Hydromechanically driven axes with state-of-the-art valve and control technology as well as a further increase in throughput performance of the injection unit make it possible for Netstal to reduce cycle times again, hence massively increasing output capacity. Thanks to the use of the innovative "Eco Powerunit" drive technology and the possibility of recovery in the intermediate circuit, energy savings of up to 10 percent can be realized at the same time. The parts-removal unit with the 2400kN and 4000kN clamping force variables of the PET-LINE series has been reworked and further optimized simultaneously. This now also offers exchange sets compatible with PET-LINE 3500.

Netstal has also refined the tried and tested Calitec© system from the PET-LINE. This innovative cooling system supports the preform cooling process by exerting internal pressure in the preform. PET preforms are therefore optimally cooled without interruption after removal from the mold. Preblow extends this cooling phase with a blowing process in the base area.

There is a clear advantage compared with the other solutions currently available on the market as complete consistency is now guaranteed throughout the entire process. The Netstal experts have had an increasing influence on key parameters, namely wall thickness and material build-up, and improved them significantly. As a result, the wall thickness in an optimal injection molding process is almost unchanging. DalPian said: "During an initial test with 1-liter juice bottles, a weMiesten keng?t laajasta valikoimasta
