WITTMANN BATTENFELD shows new one-piece MacroPower at K Fair
At K 2025, WITTMANN highlighted its new MacroPower model, which save valuable time and space in production for users. In the 400 to 600t clamping force range, the MacroPower will be available with a one-piece machine frame from the K 2025 onwards.

This model offers several advantages for the machine’s transport as well as its installation and start-up on the customer’s premises, which can be speeded up considerably with this new design.
In addition to saving time, the one-piece machine frame also contributes to reducing the error risk in setting up the machine according to the “Plug & Play” principle, since the machine goes to the customer in one piece following full examination ex works, without having to be dismantled for transport after commissioning and then re-assembled on the customer’s premises.
The new machine design also gives the MacroPower the additional advantage of a more compact footprint.
The injection unit of the one-piece MacroPower is pivotable and freely accessible from both the operator side and the opposite side. This significantly facilitates and accelerates screw changes.

The machine is equipped with the Unilog B8X control system with several control system components developed in-house. These enable a higher internal clock frequency and consequently shorter response times to sensor signals, resulting in higher reproducibility of the parts, with operating convenience and visualization remaining unchanged.
Moreover, the machine’s drive and amplifier units are air-cooled, which reduces operating costs compared to liquid cooling systems. A patented swivel locking system with only one cylinder enhances the machine’s high service-friendliness. This low-wear system ensures fast and safe locking.

In addition, a high-resolution stroke measurement system for the closing movement and pressure cans combined with the proven guidance of the moving platen by linear guides enable high-precision mold protection, as well as Expert functions such as coining, venting and ClampAdjust.
The compact range of options available on both nozzle and clamping sides across all machine series offers customers also using machines of other series from the WITTMANN product range advantages due to the uniform operating concept and fast availability of retrofit packages and service components.
A further benefit of the new MacroPower is its innovative pump concept. Up to four hydraulic units are installed in the machine, which can be set specifically to fit the application, for example to boost the performance figures, or for parallel movements of the core pull, ejector and –another novelty – the hydraulic needle shutoff system inside the mold as well.

The new MacroPower is also equipped with the KERS – Kinetic Energy Recovery System – patented by WITTMANN BATTENFELD for injection molding machines, which transforms kinetic energy released by deceleration processes into electric energy, which is then used inside the machine, for example for barrel heating. This also makes the new MacroPower extremely energy-efficient.
At the K fair, the new MacroPower 500/3400 produced a crate known as “HAIBOX” using PP supplied by Borealis and single-cavity mold from Haidlmair, Austria.
