Liebig reported on market trends characterised by an increasing demand for sensors and functionalities, for example for interior equipment in the automotive sector. “The development is heading towards greater connectivity and machine condition monitoring within the smallest possible installation space to achieve the lowest possible footprint in the production unit with regard to sustainability,” said Liebig. On this basis, he analysed product trends such as standardisation of connectors to simplify processes and reduce costs, and the demand for smaller connectors with higher functionality, as well as the integration of sensors, cables and connectivity.
Sumitomo (SHI) Demag is meeting these challenges by driving forward with the digitalisation of its machines. The fully electric IntElect series for regulating, controlling, monitoring and integrating automation and peripheral systems has an OPC-UA interface. They also have their own web-based software solution "myConnect". This central platform gives customers direct access to a wide range of fully networked services for their machine.
The third largest manufacturer of injection-moulding machines in the world is currently working on developing assistance apps, a system for setting up and optimising processes, introducing a material and knowledge database and integrating simulation tools for expanded configurations and in-depth insights into the processes. The aim, says Liebig, is an intelligent machine that can independently make predictions about part quality, machine wear and failures, and perform optimisations online.
“This aspiration is not an end in itself, but serves to produce machines with high flexibility in a cost-optimised manner,” reports the CEO. This is achieved by a combination of the company's high-quality work in Germany supplemented by cost efficiency in Asia. “Our focus is clearly on fully-electric machines for the packaging and medicine sectors. We impress with differentiated, high-quality technology rather than complex, low-quality machines, and offer our customers high efficiency with unique products.”
Particularly in connection technology, Liebig expects increasing demand for sensors and functionality, for example for interior equipment in the automotive sector. It is therefore essential for connectors to be further standardised to simplify processes and reduce costs. Smaller connectors with better functionality are also the order of the day, given the increasingly compact components.
Sumitomo (SHI) Demag’s focus is on the fully electric mechanical engineering series IntElect. “The market has greatly picked up since the beginning of this year, mainly driven by the automotive and consumer sectors, as many companies are investing in machinery there again,” said Liebig. "Our decision four years ago to consistently rely on fully electric and energy-efficient machines from the IntElect series has paid off. Turnover will thus continue increasing in the coming years, as more and more governments are pushing for energy-efficient production.”
In order to increase the added value and productivity of the fully electric IntElect series, Sumitomo (SHI) Demag chose LAPP as a new partner four years ago. “We were faced with the question of make or buy. We were looking for a trusted partner who could handle the complete assembly of the individual components for various machine sizes and reliably deliver just-in-time,” explained the CEO.
He summed up that this partnership developed very positively for Sumitomo (SHI) Demag, “The key reasons are the great core competence as a connector and cable manufacturer, the high process expertise, the lower labour costs through production of the cable sets in the Czech Republic and the lower component and quality costs.” In addition, Lapp has ensured greater transparency in the documents and optimised processes with suggestions for improvement.
Liebig illustrated the differences between the times before and after the LAPP cooperation. “As a manufacturer of injection moulding machines, producing cable sets was not our core competence. As a result, production processes could deviate from the documents and inefficiencies could not be rectified. Despite a high level of flexibility, there was consequently little motivation to correct discrepancies in the documents. There were also high labour costs,” he looked back. This is why this "make" strategy involved high component and quality costs.
Thanks to LAPP, this has changed radically, as the production of cable sets is one of the company’s core competencies. “Thanks to their extensive expertise, there is a clear production process with final testing, and inefficiencies are eliminated. Errors, discrepancies and suggestions for improvement are highlighted by LAPP and corrected in the documents once approved by us. We also benefit from low labour costs through production in the Czech Republic,” reported Liebig and summed up: “The "buy" strategy has meant that component and quality costs have fallen significantly.”
The latest collaboration with LAPP is the new M12L connector, which will soon be used in Sumitomo (SHI) Demag’s IntElect injection moulding machines. Liebig: "We have a lot of plans involving LAPP as a partner on our side."
