The MIL / compact series spotting presses are a recent innovation to optimise adjusting in the die casting sector. They feature an extensible plate exit on the backside towards the long side between the 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:
Multi Panel Touch panel
Millutensil is the first manufacturer in the world to have incorporated touch panels in their spotting presses.
A "Siemens S7 - 300" electronic PLC controls all the machine's functions.
The machine is fitted with a latest - generation "Siemens TP1200" Multi Panel touch panel. Uncluttered, clear and ergonomic, the panel offers many advantages as well as vast flexibility in customizing features, including control 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
For the versions installed on the floor only 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 ~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 the 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.
