Airmould internal gas pressure technol- ogy is a process by which nitrogen is injected into a mold cavity either partly or completely filled with plastic melt to form an internal cavity structure. In this way, lightweight parts can be pro- duced within a short cycle time and with high-quality surfaces, while also saving resources. Since the end of the 1980s, WITTMANN BATTENFELD has been developing and producing the internal gas pressure technology at its facility in Meinerzhagen / Germany with the main focus on meeting the needs of its customers and markets. This applies equally to the new upgrade Airmould 4.0, by which WITTMANN BATTENFELD has taken an important step forward. Airmould 4.0 is the only internal gas pressure system which functions without having a large control cabinet which takes up a lot of space on the production floor. The modules required are also about 15% smaller than previous versions; they After WITTMANN BATTENFELD first presented the new generation of the Airmould internal gas pressure technology to its customers at the Fakuma 2021, the development targets have now been reached, and the competitive system has already been installed and tested on the premises of several customers. With the further development of Airmould, an even more compact and user-friendly system has been created, which meets the requirements of the industry and offers its users a number of advantages. WITTMANN BATTENFELD has successfully launched its Airmould 4.0 internal gas pressure technology Airmould 4.0 modules, small and directly on the injection molding machine (all pictures: WITTMANN Group)
