KraussMaffei Group showed its APC plus at K 2016, an addition to its APC (Adaptive Process Control) that enables the correct switch-over from injection to pack-and-hold that the Munich-based company introduced at Fakuma in 2014.
APC plus lets the user choose from 20 basic materials, plus filler types, in a drop-down menu. It takes into account the specific properties of the target material.
“This makes the injection molding machine capable of, for the first time, responding to faults, based specifically on the material and taking corrective action in the holding pressure phase,” said Reinhard Schiffers, KraussMaffei's head of machine technology.
APC plus also takes the pressure-dependent compressibility of the melt into account.
The machine function offers greater precision in detecting process fluctuations triggered by changing ambient conditions such as temperature or humidity, caused by fluctuating viscosity and due to other factors. It also automatically takes measures to counter the fluctuations.
KraussMaffei said APC plus makes recycled materials easier to use. It is used for thermoplastics molding, multi-component molding or processing silicone. The company also said APC plus is ideal for special applications such as thin-walled articles or cascade injection molding.
The machinery manufacturer's U.S. operation, KraussMaffei Corp., is in Florence, Ky.
