Airmould internal gas pressure technology saves raw material, reduces the part weight and minimizes warpage, sink marks and shrinkage. In this way, the injection molding technology combines high surface quality with cost efficiency and sustainability.
To enable quick and easy startup of internal gas pressure technology, WITTMANN offers all necessary modules in a cost-effective package. Each Airmould starter package contains a central unit for 2 pressure control modules, an IoT-compliant pressure control module, the manual control unit and now also a pressure generator – a novelty in the Airmould starter package plus. All variants come with thorough application technology counselling by specialist engineers from WITTMANN. With the help of simulation and feasibility studies, the parts are examined thoroughly to determine whether they are suitable for internal gas pressure technology. Whenever a decision is made in favor of internal gas pressure, WITTMANN will take care of both the equipment’s layout and its start-up. In this way, users will benefit from the WITTMANN application technology specialists’ many years of experience and profound injection molding expertise. Existing production processes can also be adapted quickly and easily, since in many cases the molds can be used for Airmould without requiring any changes. Typical fields of application are automobile components such as handles, gardening equipment and technical components with bulges.
For Airmould internal gas pressure injection molding, nitrogen gas is injected into a partly or completely filled cavity. The pressurized gas forms a bubble at the center of the melt, which counteracts shrinkage contraction on the outside and thus eliminates sink marks. By reducing the quantity of plastic material and simultaneously enlarging the hollow space at the center, light-weight components can be produced effectively with short cycle times and attractive surfaces.
Compatible with machines of all brands
To spread the benefit from internal gas pressure technology across many different fields of application, Airmould from WITTMANN offers extreme flexibility. The packages have a modular design. All technology modules can be used via Euromap 62 on any injection molding machine regardless of its brand or model. When connected with an injection molding machine from WITTMANN, Airmold can be completely integrated into the work cell via Wittmann 4.0 and operated from the injection molding machine’s display.
WITTMANN’s concept of “everything from a single source” even includes nitrogen generation. The N2easy nitrogen generators developed and manufactured by WITTMANN extract nitrogen gas from the ambient atmosphere and supply it simultaneously to several consumers. N2easy already pays off from a daily nitrogen consumption rate of just one gas bottle.
