The mil/compact series die & mould spotting presses are a recent innovation to optimise adjusting in the die casting sector. They feature the extensible plate exit on the backside towards the longer side of the gap between columns. In this sector, moulds are relatively small, but they are often equipped with internal sliding beds that are driven by very long auxiliary cylinders that considerably increase the mould total overall dimensions.
The mil/compact series offers great advantages:
Touch panel Multipanel
Millutensil was the first worldwide to introduce a TOUCH PANEL on its Spotting presses.The electronic PLC "SIEMENS S7-300" handles all the functions of the press.
The interface is fed through the next generation TOUCH PANEL MULTIPANEL "SIEMENS TP1200". Uncluttered, clear and ergonomic, the panel offers many advantages as well as vast flexibility in customizing features, including command of the auxiliary cylinders.
Hydromechanical Fall Arrestors For The Upper Plate
Two hydromechanical fall arrestors on the right and left sides of the upper plate of the press act for the entire length of travel. The patented device (SITEMA) immediately stops and locks the plate in the event of a loss of hydraulic pressure. Unlike conventional perforated or toothed bars, this system avoids all falls of the ram of the press in the event of a hydraulic failure.
150° Tilting Press Upper Plate
Subsequently, with the down-stroke movement, the press plate rests and slides on the 2 shaped brackets up to the final ~150° position. It can be stopped in all intermediate positions. After complete closure, the press plate is automatically centred with high precision and locked by a system operated by hydraulic cylinders.
180° Tilting Of The Plate Parallel To The Floor
During the first phase, the upper plate of the press tilts by up to 100°. Subsequently, with the down-stroke movement, the press plate rests and slides on the 2 shaped brackets up to the final 180°/horizontal position. It can be stopped in all intermediate positions. After complete closure, the press plate is automatically centred with high precision and locked by a system operated by hydraulic cylinders.
ELECTRONIC UPPER PLATE PARALLELISM ANTI-UNBALANCE SAFETY DEVICE
The control system includes 4 electronic measurement devices (encoders), which continuously check the upper plate of the press position and parallelism compared to the lower plate and which are located diagonally in the four external corners of the upper plate, near the columns.
The values measured are dynamically displayed on the touch panel for the entire stroke. If the pre-set limit parameters are exceeded, the ram closing movement is immediately disabled and the error is shown on the display. Parameters can be exceeded for example because the slides or hydraulic cylinders are not retracted, or tools were left in the mould (scrapers, grinders, slip gauges, hammers, etc.).
Using this system both the press and moulds are protected from possible damage.
SPECIAL HYDRAULIC EJECTOR UNIT
Drives the movement of the extraction pins of moulds for plastics and die-casting.
Integrated Control Unit of Auxiliary Cylinders
This hydraulic device allows movement of cylinders applied on the die or mould for greater control of mobile parts (max 2+2).
Cart For Hydraulic Cylinders (4+4)
Made up of a separate hydraulic power unit interfaced to the press, available with pumps from 8 to 40 litres/min.
