Jebens GmbH to supply 24 welded steel ribs SPECIALIST suppliers of heavy flame cut components, mechanical processing and welded structures, Jebens GmbH has been chosen by Wessel GmbH to supply 24 steel ribs that reinforce two new casting ladles for a steelwork’s smelting plant. The flame-cutting expert then used the chamfering robot to produce the non vertical cut edge. In addition to the robot-guided burner, the high level of materials expertise of the Jebens team was also a major contributing factor. Throughout the process, the material’s behaviour had to be taken into account by means of a correspondingly sensitive temperature control.

According to the company something that initially seemed simple was a challengenot only for the firing specialists at Jebens, but the programming of the robot was so complex that it could only be solved by the manufacturer of the robot controller. The result was that Jebens was able to change the angle of the component over its entire length almost at will. Within a week, the first steel rib was created with the torsion specified by Wessel. The outcome was so effective that there was no need to finish the component for this specific application through milling.

With a component size of 120 x 245 x 928mm, the cutting angle of the ribs had to be changed from 72 to 84 degrees over the entire length. Significant cost and time savings were the main reasons for choosing the firing solution instead of milling, especially in view of the number of ribs required. During the two-stage process, the first step was initial cutting through autogenous firing with oxygen.

This example is an impressive illustration of how even with difficult component geometries, it is worth considering whether pre-machining or even complete machining is possible using the 3D firing technology developed by Jebens.

Pemamek responds to energy sector’s rising demands with factory expansion

required to invest in new, larger-scale production solutions,” said Pemamek’s CEO, Juha Mäkitalo. The new factory expansion increases Pemamek’s production capacity and abilities to meet the rising demand from the wind power industry. Alongside shipbuilding, wind energy is becoming another major customer sector for the company. Furthermore, the demand for heavy industry robot solutions has been increasing. “In addition to the shipbuilding and wind energy sectors, demand for heavy industry robot solutions is growing. Finnish technology expertise is appreciated worldwide, and we are eager to further strengthen its role in the global heavy fabrication industry,” added Pemamek’s vice-chairman of the board and director of global sales, Jaakko Heikonen. Pemamek’s latest factory expansion was finished in 2017. Now, the factory totals 20,000m 2 . The upcoming expansion will bring 7,000m 2 more of manufacturing, assembly and office space. The new premises are ready for production use during the last quarter of 2022. Once ready, the entire factory area will total 27,000m 2 . The new investment also increases Pemamek’s need to recruit an additional workforce. By the end of the year, the company is looking to hire 40 new employees. “The expansion has a direct impact on our need for new talents. Even now, we are running a major recruitment campaign to find colleagues for various positions. Pemamek is a great place to work for those who thrive in an international and dynamic working community with family values,” continued Mr Mäkitalo.

WELDING and production automation provider Pemamek Ltd has invested in a factory expansion and product development totalling €15m. The investment decision has been supported by a number of orders from the wind energy industry during spring 2022, as well as the growing demand for heavy industry robot solutions. The company has several ongoing negotiations for new deliveries. “Factors such as green transition and energy self-sufficiency have significantly increased the interest in wind energy. Also, the sizes of offshore wind tower constructions are growing. As an example, the diameter of a tower foundation can be over 15m. “Currently, there is no manufacturing capacity for structures of this size. Thus, tower and foundation manufacturers are
