Cycle-by-cycle part weighing and automated holding pressure adjustments are central to Krauss Maffei’s new AQC plus quality control system at Fakuma 2026. Alongside its all-electric PX machines, the company will present a side-entry robot concept for high-cavity and cleanroom applications.

At Fakuma 2026 – Booth 7303 in Hall A7 – Krauss Maffei will present solutions for greater process efficiency, higher quality, and reduced resource consumption in plastics processing. The focus will be on the new all-electric PX series with the new autonomous quality control solution AQC plus, as well as the concept premiere of the LRX plus SE for high-cavaty and cleanroom applications. Krauss Maffei will also showcase system and service solutions covering the entire value chain of plastics production.

The key quality parameter of AQC plus is the part weight. After each injection moulding cycle, the weight is measured by a scale and fed directly back to the machine control system.

Deviations – such as those caused by fluctuating material densities in recycled materials, additives, or fillers – are immediately detected and directly adjusted by autonomously modifying the hold pressure profile within the injection moulding process.

Complementing the proven digital APC plus solution, which adjusts injection moulding processes based on the viscosity index, the new AQC plus function controls the process using the quality parameter “part weight.”

This eliminates time-consuming random sample measurements. Through continuous cycle-by-cycle feedback of the actual value to the machine control system, automated 100-percent inspection is ensured and documented.

Additional benefits of AQC plus: scrap is reduced, process stability is improved, and production with low material consumption and particularly tight weight tolerances is enabled.

Autonomous production in the smallest footprint

The space-saving production cell of the new all-electric PX 80 (800 kN clamping force) at the Krauss Maffei booth demonstrates a compact, productive, and efficient solution for manufacturing technical components.

The LRX plus linear robot removes the polyamide electronic components from the mould (partner: Wieland Electric), weighs them, and places them on an integrated conveyor belt inside the machine enclosure.

A space-saving mill (partner: Getecha) grinds the sprue and feeds it back into the processing cycle. The CE-compliant system enables significantly higher production density: instead of four machines with linear robots, five systems can be operated on the same floor space.

LRX plus SE for easier side-entry automation

With the new LRX plus SE linear robot, for the first time Krauss Maffei will present a side-entry concept for demanding high-cavity and cleanroom applications with particularly short removal times at Fakuma 2026. The automation solution is based on the proven LRX plus platform and combines high dynamics with a compact system layout for site-entry demoulding.

Within a small footprint, the LRX plus SE offers maximum flexibility in positioning axes as well as additional space for downstream processes such as quality control, packaging, or other medical technology peripherals. Reinforced axes and drives, optimized components, and a cleanroom-compatible design enable high removal speeds and payloads.

At Fakuma, a new all-electric PX 160 equipped with a 96-cavity mould from Männer by Spectrix will produce protective caps for insulin pens. The mould partner is an expert in high-precision moulds and needle-valve hot runner systems. Excellent balancing, a compact yet robust design, and high-precision cavities ensure reliably high output with a consistently high part quality.

The exhibit solution demonstrates the perfect synergy between precision mould making, an all-electric injection moulding machine, and compact side-entry automation for efficient and economical production processes in medical technology – for example, through space savings and short demoulding times.
