Legendary local combat in the Satakunta derby

At Lehtosen Konepaja, Satakunta derby, i.e. Ice hockey champion’s league games between Porin Ässät and Rauman Lukko, are intensively followed. The teams belong to the same group, so they play six matches against each other during the season. Lehtosen Konepaja has many sports enthusiasts who from season to season have encouraged their favourite team, which is alternately Ässät or Lukko. In the history of the league, these two teams have already fought with each other 250 times and the events at the Satakunta derby bring emotions to surface. In the first derbies of the season 21.10.2022 in Pori and 22.10. In Rauma, Lehtosen Konepaja and LEKO Group were involved in supporting Satakunta sports.

At the Peipohja factory, ice hockey is played on own outdoor ice

Sports are actively played at Konepaja. Ice hockey is one of the most popular sports, and not only because there is a suitable outdoor ice next to the factory. It has hosted many games and tournaments played between colleagues, in which the management of the company is equally involved. Erkki Lehtonen is indeed known in hockey circles as an enthusiastic supporter and the LEKO Group has sponsored the sport from juniors to league players.
Sports-minded company wants to be involved in activities that provide experiences and, as a close community, get people in its area moving, from children to adults.

Satakunnan kiekkoheimot – documentary series

Porin Ässät and Rauman Lukko – match always gets a lot of supporters out and about and the support of both home teams is palpable. Traditional clubs have also received their own documentary series, which follows the events of the Finnish champion’s league. The teams from Satakunta will become familiar to the whole of Finland when C More tells about the hockey history and first steps of Lukko and Ässät.


LEKO Group was demonstratively involved in the match when Porin Ässät and Rauman Lukko encountered each other at the Rauma Kivikylä arena on 22.10.2022. Erkki Lehtonen, Managing Director of Lehtosen Konepaja, was also in the grandstand.





TK-Vilmet shifts from oil heating to heat recovery

Technical space of TK-Vilmet’s welding hall’s heat recovery system during the construction phase.

TK-Vilmet has large-scale investment projects in order to increase production capacity and enhance energy management. Recent acquisitions, such as the modern Tos Varnsdorf machine tools and the Hyundai HA006B welding robot station are part of the company’s continuous development. An important step is the abandonment of oil heating, which is part of the sustainable recovery of the economy and a response to the climate crisis and natural degradation. The heating renovation of the welding hall represents new technology and translates to economic savings for the company in addition to environmental impacts.

Machine shop TK-Vilmet is renewing its production environment

With the help of an energy subsidy received for the project, an investment related to energy saving and efficiency was carried out at TK-Vilmet, which promotes the introduction of new technologies. A new solution for the abandonment of oil heating is a waste heat recovery system of the welding hall, a pilot project of which was also carried out in Lehtosen Konepaja, a group company of LEKO Group. Positive experiences gained from the introduction and functioning of the system were transferred to the benefit of TK-Vilmet and the renovation was carried out in record time in approx. four months. In heat recovery of ventilation, the heat energy of the exhaust air is transferred back to the supply air and to the heating system of the property. This improves the energy efficiency of the building and reduces heat loss caused by ventilation.

Minimal energy expenses and good air quality

According to the experience gained, heat recovery saves up to 70% of energy and the consumption of heating energy is reduced by 30-40%. In addition to the minimum energy expenses, the air quality remains extremely good, as can be seen at Lehtosen Konepaja. In practice, the benefits are also noticed in the fact that during the winter, the heat does not escape from the property and during the summer, the ventilation is sufficient. There were two ventilators installed in the welding hall of TK-Vilmet and when the system was fully operational, it already paid itself back within two months. Plumbing and equipment installation in the welding hall did not hinder production, but it continued without interruption during evening hours and weekends. The decommissioned above-ground oil tank was delivered empty for metal recycling.

New energy-efficient technology takes care of heating instead of oil heating.
An example of TK-Vilmet’s heat recovery project was the corresponding renewal of Lehtosen Konepaja, which saves up to 70% of energy.

Savings and system benefits are verified from the energy meter data.

Heat recovery fluid from the heat recovery unit passes along the heat recovery line to the technical space.

TK-Vilmet increases rate of machinery capacity

TK-Vilmet continues making new investments, and as production increases, the latest acquisition in the subcontracting machine shop – Tos Varnsdorf WHN 130 Q – adds to the capacity of the comparable machine purchased in 2020. Both machines are tailored to match the workshop’s requirements, and compared to the previous one, the new machine’s Y-axis motion has been increased from 2000 to 2500. The Czech TOS Varnsdorf a.s. is a manufacturer of metal machining equipment with long-standing traditions and modern, CNC controlled, and reliable machinery. As we are already familiar with TOS broaching machines and our staff has received extra training for their use, commissioning the new machine went smoothly and the whole production capacity was quickly up and running at the workshop.

The subcontracting machine shop TK-Vilmet is part of the LEKO Group. In addition to joint administration, we have synergy gains from the large-scale machine workshop of an internationally developing group and a service concept for the metal industry. These enable TK-Vilmet to offer their customers bigger and more demanding wholes.

Basics of the new machine:
Tos Varnsdorf WHN 130 Q
Control: Heidenhain TNC 640
Spindle : Ø 130 mm, 3000rpm, 41 kW, cooling through 40 bar, 60 slot automatic tool changer
Range: X=3000, Y=2500, Z=1250, W-800
Carousel table: 1400 x 1600mm, 8000 kg




More technological expertise and resources for welding

Lehtosen Konepaja is again investing in the productivity of welding technology and is determined to invest in its machine base.
In heavy machinery manufacturing, highly automated solutions and welding robots increase the technological expertise required for demanding customer work.
For example, machine frame manufacturing typically consists of parts manufacturing, welding, heat treatment, machining and surface treatment.
In particular, our welding and surface treatment departments are top-notch and the main objective is still to increase the welding power and productivity. Our new acquisition is a submerged arc welding tower ESAB CaB 460 M, 7×5 M.

Submerged arc welding tower ESAB CaB 460 M, 7×5 M

The submerged arc welding tower ESAB CaB 460 M, 7×5 M multiplies production power, speeds up welding and improves the lead time of production. The submerged arc welding tower increases productivity, e.g. compared to automatic welding even five times, not to mention manual welding. Robot welding provides uniform and good quality quickly and cost-effectively. Especially for thicker materials, productivity. Submerged arc welding also has a significant safety and environmental aspect, as it does not emit heat, light or welding fumes.

Benefits of submerged arc welding:
• Speed and cost-effectiveness
• Suitable for large material thicknesses
• Suitable for handling large pieces
• Ensures consistent and good quality
• Best welding process for the working environment
• Relieves the employee from manual, physical welding
