Loramendi has applied its unmatched engineering resources in Core Making to Vertical Moulding. The result: an extremely robust and precise flaskless vertical moulding machine which introduces a number of improvements.
Loramatic compacts the moulds squeezing on both sides, obtaining optimum mould compaction. The mould can be squeezed equally on both sides or have different strokes since the motion controls are independent. The blowing slot remains in the middle of the mould, a property especially useful for reducing wear of pattern plates.

The weight and shock loads from the pattern and support frames are no longer transmitted just via the guide shafts. The weight is now also supported by a separate guiding arrangement. This additional support lengthens the life of the bushings. Shorter axial guides have been fitted and the main hydraulic group has been relocated to leave free space for a support and rolling system for the crosspiece, contributing to easier and cheaper maintenance. The shock absorber mounted to stop the core mask when assembling cores into the mould is automatically adjusted according to pattern parameters and core mask thickness. Thus, no operator input or adjustments will be necessary when changing patterns.
The venting surface in the mould chamber has been increased to improve overall mould compaction. The machine is fitted with a laser scanner, which detects loose material on the mould base plate prior to closing. When alerted, the system signals the operator to take corrective action, or can signal to the pouring unit to avoid pouring and prevent run outs. The problems caused by bad moulds are thus reduced. When changing patterns, the correct machine and mould parameters are automatically uploaded to the moulding machine thanks to a pattern or job identification system included in the machine.

The Mould Transport System has undergone a deep transformation. Its main body is free of any mechanism, minimising the time required for inspection. On the other hand, the fact that these mechanisms are located at the side protects them against falling molten metal. Some parts are now made of Titanium, improving the service life due to its better wear properties. The design of these parts is such that they can be replaced independently without needing to replace the complete mechanism.The side clamps in the pouring area will improve the dimensional tolerance of the castings. These clamps do not distort the alignment of the mould string and are heated to avoid sand sticking.
Loramatic also presents new main hydraulics. Thanks to independent cylinders, movements can be overlapped and shorter cycle times obtained giving a high production. Movements are now smoother with the redesigned wedge cam, which is facing down to avoid accumulation of sand over it, and produces uniform stresses on the rods during the cycle.
