Airmould Wittmann Battenfeld’s Airmould internal gas pressure technology injects nitrogen into an injection mold cavity that is partly or completely filled with melt. The pressurized gas forms a bubble at the center of the melt, which counteracts shrinkage on the outside and eliminates unsightly sink marks. Airmould technology reduces the amount of plastic used and produces lightweight components with short cycle times and good surface quality.
What’s new? Airmould Next, Wittmann Battenfeld’s next-generation technology. Wittmann has redesigned both the pressure control module and the manual operating device. The pressure control module previously was available in two different versions, with control via either a handheld device or an external control cabinet. The company has replaced those versions with one uniform system. The Airmould Next package includes a nitrogen generator unit that extracts nitrogen directly from the air and a compressor unit that compresses the nitrogen up to a maximum pressure of 330 bar. On Wittmann Battenfeld injection molding machines, the pressure control module can be set directly via the primary machine’s control system. On competitors’ IMMs, an additional manual operating device is required. The new system will be available after Fakuma 2021 in October.
Benefits Improved user friendliness, better quality monitoring and a compact design. With a lower upfront investment than the previous technology, Airmould Next also is easier to operate, saving time and costs.
