PWF Kunststofftechnik GmbH, Grindellingen, near Hamburg, Germany, specializes in the production of complex connector housings for the automotive industry.The company uses the latest injection molding technology from WITTMANN BATTENFELD to meet its stringent quality standards.
PWF has been considered a model of top-quality, high-precision molds since 1969. PWF Kunststofftechnik was founded in 1990. Since its inception, the privately owned company has been growing at an annual rate of 5% to 10%. 2016 In 2006, the company achieved sales of 16.5 million euros, which has doubled its sales since 2010.
The company's main business is the production of complex plug connectors for the automotive industry.WPF's customer base includes the world's leading automotive components suppliers who source molds and final components and complete assemblies from PWF Inc. Except for the automotive components Vendors collaborate to achieve approximately 90% sales, and the company is also active in industries such as home appliances, laboratory and medical equipment, HIFI technology and sensors, etc. Production programs include such items as meter covers, sensors for ventilators, pneumatic Valve housing, test tubes that change color at different temperatures, and many more.
In the field of mold making, the company manufactures about 50 high-precision molds per year.A mature long-term international distributor network, together with partners in Korea, Portugal and China, ensures that PWF can provide their clients with them without any problems The molds needed to meet the needs of their international customers for mass ordering of parts.
The special capabilities of PWF are that the company has great flexibility, for example, can produce the same series of products from 200 to 60 million batches. Each year, PWF processes about 200 different materials involving 150 different Almost all of the standard engineering plastics are used, including heat-resistant materials and thermoplastic elastomers, etc. In 2016, the company produced 976 different products from 393 different molds with 95% delivery The performance achieved a total of 313 million pieces of plastic output, and to produce such a large number of products, PWF machines operate 362 days a year, continuously and continuously throughout the day.

As a result, the injection molding machines used by PWF, including automation and peripheral equipment, must meet very stringent requirements. PWF has a total of 49 injection molding machines with a clamping force range of 150-4000 kN. In 2017, WITTMANN BATTENFELD supplied PWF Four all-electric injection molding machines, three of them from the EcoPower range, with clamping forces of 550 kN and 1100 kN, each equipped with the latest Wittmann linear robots.The recently delivered machines come from the MicroPower range with 150 kN clamping force, designed for injection molding of miniature parts with an integrated turntable, a component removal system designed by Will for this machine, a powerful DRYMAX Micro material drying Machine, along with an imaging-based quality inspection system and a cleanroom module that provides a 6-stage air cleaning production environment per ISO 14644-1 standard, allow PWF to deliver low-cost production of top-quality micro-components to the highest standards.

PWF relies not only on the company's state-of-the-art all-electric injection molding machines, but also on the automation and peripheral equipment of the Witten Group, and as a result, most of the injection molding machines installed at PWF are equipped with powerful linear robots, WITTMANN's die temperature, mixers and shredders are also being used in the PWF production plant, and the company's overall material handling needs are met by the mighty Central Material Handling System.

In addition to a good price / performance ratio, PWF's requirements for its injection molding machines are above all a high degree of machining reliability, which is one of the most important attributes for the auto parts supplier. In addition, PWF general managers Mathias Wernicke and Volker Hansen The low energy consumption of machines, first of all, is the low noise level of the machines, which, of course, must be easy to operate and have moderate maintenance requirements, however these demands on the machine are constantly changing due to the wide range of products. What we need is a low-cost, quiet-running injection molding machine that is easy to handle and can be expanded and retrofitted to meet new needs without problems. "With a simple Windows-based control system and a wide range of options , The injection molding machine from WITTMANN BATTELFIELD fulfills all of these requirements. "Mathias Wernicke explains that quality service is as important as quality machines. In addition to quality and available services, Wernicke emphasizes the importance of people, 'I hope service engineers will be able to communicate well with our staff so that they can work together quickly and efficiently The problem was solved, "explains Wernicke Mathias Wernicke is very satisfied with the sales and service team at WITTMANN BATTENFELD and the training of its employees on the WITTMANN BATTENFELD machine.
