Airmould This Wittmann injection molding process involves injecting nitrogen into the mold cavity, using the gas to displace material, resulting in lightweighting and a reduction in the amount of material that’s required. The nitrogen and pressure generation equipment necessary for the process — including injection modules, Airmould machine nozzles, compressor, nitrogen generators and pressure control modules — is available in different sizes and with varying capacities, and can supply individual machines or function as a central system for several machines. Along with lightweighting and material savings, the Airmould process results in reduction of part costs and the prevention of sink marks. Typical fields of application are automobile components such as handles, gardening equipment and technical components with bulges.

What’s new? An Airmould Starter Package Plus, which now includes a pressure generator. Wittmann’s N₂easy nitrogen generators pull nitrogen gas from the ambient atmosphere and supply it for the injection molding process simultaneously, eliminating the need for gas bottles. 

Benefits Simplified access to internal gas pressure technology. The Plus packages have a modular design and can be used on any injection molding machine regardless of its brand or model.
