KraussMaffei has completely redesigned its all-electric PX injection molding series and plans a market launch at K 2025 across clamping forces from 800 to 2,000 kN. The new platform combines a compact mechanical layout with updated drive technology and a modular enclosure. All main axes, including a newly electric ejector, are servo-driven. According to the company, this improves cycle performance and cuts energy consumption by about 20 percent. Optimized arrangement of components and a slimmer housing reduce the machine footprint by approximately 20 percent. Key characteristics from the prior PX generation remain, notably large tie-bar spacing for complex and heavy molds, wide support of the movable clamping plate for platen parallelism, linear guides for precise and efficient movements, and integrated energy recuperation. Temperature control and cooling options have been revised, including direct water distribution to the clamping plates. Lower pressure losses allow the use of smaller temperature control units, and customers can choose from simple configurations to digital single-circuit monitoring. A new hot runner controller adds digital functions such as booster mode and fault detection. The machine can be equipped with a compact servo-hydraulic auxiliary unit for energy-efficient actuation of mold core pulls and cascades. “It is the most modern all-electric injection molding machine in the world. We have made it more compact, more productive, and more sustainable from the ground up,” said Jörg Stech, chairman of the management board of KraussMaffei Technologies GmbH. The company positions the series as a flexible solution for technical components, medical technology and packaging applications.
Redesigned platform cuts footprint and energy use
The new PX series centers on a reworked machine topology that shortens the machine bed and consolidates drive components. In addition to fully servo-electric main axes and ejector, the platform offers an optional servo-hydraulic power pack for auxiliary functions to support complex tooling. The enclosure adopts a modular, space-saving design to facilitate integration of peripherals and to simplify cleanroom adaptations where required. The retained large tie-bar spacing expands mold compatibility, while the wide support of the moving platen and linear guidance target precision and energy-efficient motion. Energy recovery remains standard.
Control and connectivity with MC7
The PX introduces the MC7 control generation, a web-based platform designed to enhance usability and connectivity. The interface follows an intuitive visualization concept with clear displays and extended functions for setup, operation and maintenance. KraussMaffei states MC7 meets future requirements of the Cyber Resilience Act to strengthen protection against cyberattacks and to enable seamless digital integration of the machine.
World premiere at K 2025: The new all-electric PX series with new MC7 control system from KraussMaffei sets new standards in terms of productivity, cost efficiency, sustainability, and safety.
Thermal management and hot runner control
Cooling and temperature control have been updated, including direct distribution to clamping plates to reduce pressure losses. This allows users to downsize temperature control units, contributing to overall efficiency. The offering spans from basic designs to digital single-circuit monitoring. The hot runner control developed by KraussMaffei adds digital features, such as booster mode and fault diagnostics, to help stabilize processes and raise overall productivity.
Application showcase: PX 80 production cell for technical parts
A compact PX 80 cell with 800 kN clamping force highlights space and cost efficiency for technical components. Using a mold from Wieland Electronic, the system produces electronic parts made of polyamide. An LRXplus linear robot removes the parts and places them on an integrated conveyor inside the machine enclosure. The CE-compliant cell design enables higher production density, so that five systems can fit where four conventional cells with linear robots would typically be installed.

Cleanroom-ready: PX 200 for medical molding
The PX 200 in cleanroom configuration targets medical and pharmaceutical requirements on a compact footprint. In the presented setup, a high-performance mold from Kebo AG produces 96 inner needle protection caps for insulin pens in 4.5 seconds. The modular enclosure concept supports straightforward integration of laminar flow boxes and conveyor belts, aligning with cleanroom workflows while maintaining precision and productivity.
Compact, fast, cleanroom-compatible: A PX 200 produces 96 inner needle protection caps for insulin pens in just 4.5 seconds at the KraussMaffei booth – perfect for the requirements of the medical and pharmaceutical industries.
Presentation at K 2025
The fully electric PX series will be shown live at K 2025. KraussMaffei will exhibit in hall 15, booth C24.
