New injection moulding machine from Sumitomo

With the new „IntElect“, Sumitomo (SHI) Demag Plastics Machinery GmbH, Schwaig, presents a completely new generation of electric injection moulding machines. Design innovations reduce the space requirement and improve the accessibility, ergonomics and precision of the machine.

The new machine is now available as a complete series with 500, 750, 1,000, 1,300 and 1,800 kN clamping force. The 1,800 kN machine extends the new IntElect series The new IntElects have been upgraded both in terms of clamping force and tie-bar width, closing the previous gap to the midsize IntElects. Thanks to the More comprehensive modularity and the inserted intermediate size injection moulding machines with up to five screw diameters per injection unit. The new design makes the IntElect significantly more compact than its predecessors: the required footprint is on average ten per cent smaller than that of comparable all-electric competitor machines.

With the modernised motor technology and expanded storage potential for braking energy, it has been possible to reduce the Energy efficiency of the IntElect machines. The savings compared to comparable all-electric machines amount to 20 per cent.

„Our aim was to be honestly innovative. This means that the new IntElect does not have a political price tag, but we have worked for five years to make the new machine more compact and to make its use more productive and efficient,“ emphasises the CEO Gerd Liebig.

Sensitive protection and maximum mould support are important components of the machine concept. To this end, the IntElect offers a package of different options, from the standard sensitive profile monitoring of the mould protection force to monitoring the progression of the ejector force and injection pressure. The high-quality linear guide system guarantees maximum platen parallelism up to the symmetrical application of the nozzle contact force. For increased Production safety The mould mounting platens, which were redesigned using FEM analysis, also contribute to this. The rigidity of the moving and fixed platens has been increased by up to 30 per cent.

Compact and economical

This development focussed on cost-effectiveness and compactness. Based on the electric drives manufactured in-house, which are specially produced for use on injection moulding machines and are constantly optimised for this purpose, the Attractive pricing of the machine series has been significantly increased. „The price difference to hydraulic machines has been closed further and we now offer an improved machine series that combines cost-effectiveness and a favourable price. ROI of less than one year have been achieved. The demand from our customers for the first test machines, which have already been almost completely purchased by the test customers, is very promising,“ says CEO Gerd Liebig.
