KraussMaffei CX Molder Shines at Fakuma


KraussMaffei (Munich) chose to a make a small impression at Fakuma in Friedrichshafen, Germany. At its stand, the company is featuring its CX small machine series with clamping forces ranging from 350 to 1600 kN, highlighting a number of innovations that were a direct result of asking customers what they wanted in their molding equipment, said Hans Ulrich Golz, President of the company’s Injection Molding Machine group, at a press conference today.

“We were able to implement all of our customer requirements,” said Golz, namely a 10% reduction in energy consumption, 30% reduction in decibel count, a 20% reduction in oil usage, and a 15% increase in speed. Combined with a 25% improvement in efficiency and faster setup times, “that’s 100% added value for our customers,” said Golz. I’m not sure the numbers really add up, but it does make for a cute value proposition.

The two-platen design of the CX requires less installation space than the longer three-platen models, and the cantilevered clamping unit leaves space underneath for mold temperature controllers and conveyor belts, according to KraussMaffei.

A new integrated servo sprue picker, developed by KraussMaffei’s automation division, maintains the system’s low profile. A telescoping design enables its use in low-ceilinged halls.

The machines are also equipped with a recently developed ejector coupling that facilitates mold changes and can compensate for small axis offsets between the mold and ejector.

The molders come with the new Adaptive Process Control (APC) system, which the company now offers on all of its electric and hydraulic machines. APC adjusts the changeover point and holding pressure profile in each cycle to the current melt viscosity and flow resistance in the mold. This makes it possible to compensate for deviations in the same shot, resulting in significantly lower fluctuations in part weights, says the company.

The machines may be small, but KraussMaffei thinks it has some pretty big achievements to talk about, and Fakuma visitors seem to agree.
