Motorized mold height adjustment

In order to produce the locking force necessary for a closed mold, the closing stroke of the machine must be matched to the current mold height, which can differ for each individual mold. To achieve this, it must be possible to move the entire mold-closing unit lengthwise. This typically occurs by means of a mold height adjuster that is powered by a hydraulic motor and acts on all four columns of the machine. The AFS/AFM60 PROFINET encoder is used to provide the accompanying path measurement system for controlling the mold closing unit. This absolute encoder delivers high-precision detection of the position and status of the closing axis at a resolution of up to 30 bits.
