KraussMaffei’s CX series become faster & more energy efficient

  • 10% less energy consumption, 15% faster
  • Most space-saving sprue picker on the market

KraussMaffei has reworked its CX small machine series in the clamping force range of 350 to 1600 kN. From hydraulics to control software, almost every component in the tried-and-true CX machines was subjected to testing and numerous improvements were defined. Customers can benefit from low expenses for energy, space, time and material.

10% less energy consumption, 15% faster

The new CX in the series of small machines up to 1600 kN now features a number of improvements in regards to energy consumption, speed and general machine performance. According to the company, the new machine clamps about 15 percent faster on average. This is achieved due to optimized interaction between the new valve technology and hydraulic switching concepts. At the same time the machine uses up to 10 percent less energy, features 20 percent reduced oil volume and is 30 percent quieter due to a new soundproofed cover.

When it comes to overall size, the two-platen design of the CX takes up less installation area than longer three-platen models. And the machine provides more space for molds. The customer has option of selecting different platen sizes and distances. This makes it possible to enlarge the mold area by another 40 percent. Additional advantage: For some applications, the machine can even be sized smaller than before. The complex design of molds for multi-component injection molding machinery often makes them too large for the machine size that has sufficient clamping force. “The 13 percent wider platens enable such applications to be produced on a CX 130, while the competition needs a 160-ton machine” explains Jochen Mitzler, Head of Strategic Product and Technology Management at KraussMaffei.

Adaptive Process Control as standard

Additional features specifically for small machines include the ejector coupling and the BluePower Vario Drive concept. Like all machines from KraussMaffei, the new CX is equipped with the new Adaptive Process Control system (APC), which can compensate for fluctuations in the injection molding process.

Most compact servo sprue picker on the market

The new servo sprue picker features a very compact design. The telescoping stroke makes the picker particularly well suited for use in low halls. The detached sprue is stored within the standard machine’s housing. This means that a side expansion in the form of a protective fence is not necessary. This way, four machines can be installed in the same installation area instead of three. The servomotor enables the sprue picker to operate extremely fast and saves expensive compressed air compared to pneumatic drives.

Rapid tool changes

A newly developed ejector coupling makes it easier to change molds and is capable of compensating for small axis offsets between the mold and ejector. An optional bayonet quick mold clamping system enables particularly short mold set-up times. In addition, KraussMaffei offers manual bar-pulling devices for mold changes, as well as automatic bar-pulling devices for frequent changeovers.

Special adapter for small shot weights

With the help of special adapters for the plasticizing unit, the machine can easily be adjusted for smaller shot weights. The adapter concept enables the adaptation of up to two injection unit sizes. Plastics processors benefit from this flexibility and can, for example, eliminate the use of large, expensive sprues.
