Fast, Faster, Fastest
Sumitomo (SHI) Demag
The booth of Sumitomo (SHI) Demag Plastics Machinery GmbH, Schwaig, Germany, will feature two high-performance El-Exis SP machines for packaging applications. By virtue of its "speed compression" – compression at the highest speed of mold and injection movements – the El-Exis SP 420 will show that efficiency gains can still be made even in the extreme thin-wall sector. The machine will produce four polypropylene trays per cycle in a 2+2 stack mold. This is accomplished by means of the injection compression function in which the melt is introduced into the cavity before the mold is fully locked. The clamping movement of the machine promotes distribution of the melt in the cavity, reduces the demand for injection pressure and hence for clamping force while ensuring uniform pressure distribution and lower residual stresses in the finished part.
An El-Exis SP 200 will produce four decorated cups in a cycle time of less than 2 s in a 4-cavity mold. Sumitomo (SHI) Demag believes that the two exhibits will be the fastest machines for producing decorated cups with injection compression function at the show. Current El-Exis SP models are available in clamping forces ranging from 1500 to 7500 kN and all are equipped with an OPC/UA interface for connectivity in accordance with the standards of Industry 4.0.
In addition, an all-electric IntElect 450 will produce crystal-clear polycarbonate headlight covers in a highly efficient production cell. The exhibit is intended to highlight the benefits of all-electric concepts for injection molding larger parts and is seen as confirming the "Automotive Goes All-Electric" trend. The smaller 500 kN IntElect will be unveiled for the first time at the trade fair, with an as-yet unpublished innovation.
