History

2021
Exporting excellence

The turn of the decade saw a major leap in Power Tech Group’s international trade, and export business has continued to grow in 2021.

The company’s biggest single order to date was secured in 2021 in the oil and gas industry in Murmansk, Russia.

2019
Power Tech Group

A business group is formed again: Power Tech Group turns its focus on industrial machinery, while parent company Kotka Marine Oy concentrates on real estate, warehousing and supporting activities.

In the previous year, Kotka Power Tech had gained ownership of the entire Pikku-Hietanen area. Now, the quay at Pikku-Hietanen became the home base of icebreakers Nordica and Fennica: it was a sign of trust in the company.

Kimmo Lappalainen was elected the new CEO of Power Tech Group, while Kalle Sundberg focused on his duties as chair of the board.

2017
Acquisition of the Tohmajärvi workshop

Kotka Power Tech acquired the MFG Tohmajärvi workshop from Kesla in 2017.

Total staff numbers grew to 160.

2016
The most extensive vertical turning machinery in Finland

The company bought a new PowerTurn 4000 turning machine, thereby increasing the vertical turning capacity to five meters. Power Tech now had the most extensive vertical turning capacity in Finland: eight turning centers ranging in size from 500 mm to 5,000 mm.

Investing in a new coordinate-measuring machine enabled quality control at even more accurate levels, broadening the company’s customer base.

2013
The company turns 30

Kalle Sundberg: “Thirty years is a long time for us humans. In a company’s life it is even longer, when you consider economic fluctuations, local structural changes and global changes in the world economy."

Power Tech turned 30 on the same day its founder Oiva Sundberg turned 75. Power Tech Group’s anniversary was celebrated in Meriniemi, Kotka on 17 August 2013.

Around this time, the company also hired its first export manager.

Total staff strength was 80 people.

2012
Implementation of a CAM system

The company acquired a new CAM system, thus enabling CAD models to be directly prepared for machining.

A 30-ton rotating table was purchased in Savonlinna.

2011
Assembly transferred to Pikku-Hietanen

The Kaarniemi facilities were getting too crowded for assembly work, while Pikku-Hietanen had space in spades. To solve the issue, a new company, KM Maint, was established on the Kotka Marine premises to take on the assembly and maintenance operations as well as warehousing.

Out of the 3,500 square meters of spare room in Hietanen, space was also let out to business partners and other companies.

The local newspaper Karhulalainen published an extensive article on the company. The headline read: “Family company Power Tech proves it: Technology is the region’s way forward”.

2010
Heading for the international market

The company’s quality, welding and environmental management systems were certified according to the international EN and ISO standards. This made it possible to launch more complex products in the international market.

2009
In the grip of the financial crisis

The financial crisis that had started in the United States severely reduced the number of orders in the latter part of the previous year, resulting in the collapse of revenue.

Kalle Sundberg: “We had already made our policy decisions. Now we just had to figure out how to survive the collapse and rise again.”

Like so many others, Power Tech was forced to start cooperation negotiations. To reduce the toll of layoffs on staff, an alternating-weeks schedule was adopted. This allowed the company to maintain its ability to react to sudden orders and keep its delivery times short.

The company also acquired the remaining shares of Hydturner Oy (Hydturner was entered in the trade register as auxiliary company name on 18 October 2011).

The staff numbered 63 people.

2008
Forward with new appointments

Automation Engineer Veli-Matti Korhonen was appointed as the CEO on 22 February 2008. He had been made vice-CEO already in August of the previous year. Kimmo Lappalainen was appointed sales engineer, having brought a significant amount of business to the company and paved the way for international operations.

A new machine shop was built and a new vertical turning machine Powerturn was purchased.

Towards the end of the year, the company began to feel the consequences of the financial crisis that started in the United States, as orders began to dwindle.

2007
Expanding business to Savonlinna

Power Tech became a parent company again when it acquired a minority shareholding in Hydturner Oy, a Savonlinna-based company operating in milling, boring and turning.

A machine shop was built in Savonlinna and equipped with a 14-meter Fpt Sirio milling machine. Another extension was added to the Kaarniemi machine shop and a Mazak Integrex 1060v machining center was set up. The first 5-axis turning center was put into service.

The company bought the second half of Kotka Marine Holding Oy and changed its name to Kotka Marine Oy.

2006
Sale of Power Service

The company sold all its shares in subsidiary company Power Service to Empower Oy. With the transaction, Power Service’s workshop in Hietanen also transferred to Empower. Power Tech retained ownership of half of the Hietanen property company Kotka Marine Holding Oy.

The company began to expand the Kaarniemi machine shop.

The staff numbered 57 people.

2005
The birth of a business group

Power Tech bought Power Service from Kalle Sundberg, and a business group was born.

2004
Awards and machines

Kalle Sundberg received a business award from the city of Kotka on 2 April 2004.

The company extended its range of machinery with a CNC boring machine, CNC vertical turning machine and a CNC machining center.

Staff strength was already at 101 people.

2003
Twenty years in business

The company turned 20, celebrating its anniversary together with customers and staff on Varissaari island in Kotka.

Staff numbered 95 people.

2002
Investing in Pikku-Hietanen

The company bought the rest of the Pikku-Hietanen dock area together with T2 Invest. The deal included the plate and welding workshop, welfare facilities building, quay, and a long-term lease contract with the city of Kotka for the ground and maritime area.

A new CNC milling center and equipment was purchased.

2001
Last purchases in Finnish markkas

The purchases of the last “markka year” included an Fpt milling machine and equipment, an Fpt machining center and equipment, a Geminis CNC turning machine, a Mazak CNC turning machine and FMC storage for long products.

Staff numbers had risen to 98 people.

2000
Power 2000

At the start of the 2000s, the company launched the Power 2000 project to make its production processes entirely CNC-based. It invested heavily in machinery, enterprise resource planning systems and quality.

Another Puma CNC machine was bought, along with a new forklift and a profile bending machine.

1998
New office facilities

A new, modern security system was installed and new, spacious office and welfare facilities were set up.

The company also bought a balancing machine and a plasma cutter.

1997
The return of Kotka Power Service

Kotka Power Service Oy was re-established to take over repair and maintenance operations. A hall was bought in Pikku-Hietanen to house the new unit.

Kotka Power Tech Oy concentrated on machine workshop operations and its machine shop was expanded.

The company quality manual had been completed the previous year.

The newest purchases included a Roundo bending machine, a crane, a Puma CNC turning machine and a 16-ton traveling crane.

Staff strength was 80 people.

1995
From investments to growth

The company took a critical step towards a new operational model with new, partnership-style machine investments and contract manufacturing. In the previous year, the ISO 9002 quality system was adopted.

Investments in the machine workshop grew with the purchase of a vertical turning machine and a press brake, following the acquisition of a new plate cutting machine the previous year.

Kotka Power Service merged into the Tech company on 25 January 1995, and staff numbers jumped to 54 people.

1993
Learning from the depression

The ability to invest in machinery on a large scale has been the requisite of the company’s development. The 1990s depression taught Kalle Sundberg that internal financing is the only safe way to invest.

“Buying the 800,000-markka boring machine was a good lesson, and nearly all subsequent investments have been financed internally.”

1992
Generational change

A generational change took place on 11 December 1992, when Kalle Sundberg took over the responsibility for developing the company. Father Oiva Sundberg remained a minority shareholder and dedicated more and more time to his beloved horses, winning a great many awards.

The machine shop in Kaarniemi was expanded.

1991
Parent company Kotka Power Tech Oy

The company decided to divide its operations into two: the new parent company was named Kotka Power Tech Oy, and a new company, Kotka Power Service Oy, was established. Its owner and the CEO of the entire group was Kalle Sundberg.

New, more spacious office facilities were taken into use on the second floor. The group also made some purchases: a new CNC boring machine, ADP-based production management, DNC file transfer and two NMT cellular phones.

The autumn of 1991 revealed the depth of Finland’s financial crisis, soon after the major investments in the new boring machine and a new machine shop: “Suddenly we were stranded with our million-markka machine!”

1990
Expanding facilities and the machinery range

The Kaarniemi machine shop was expanded and a new CNC milling machine and a CNC turning machine were bought.

Staff numbers had risen to 35 people.

1988
Family company grows

The company hired its very first office worker. The new office facilities weren’t yet ready, so the new accountant began work at Oiva’s home.

Oiva Sundberg’s son Kalle Sundberg joined the family company in 1988 after graduating as a shipbuilding engineer from the University of Turku.

A new plate workshop was built, as well as new office facilities. The first CNC turning machine, a Kiwa Exel machining center, and the fifth center lathe were bought. The company also purchased its first computers and an ADP-based production management system.

1987
From ships to factories

More and more of Kotka Power Service’s maintenance clients were factories instead of ships. The client base grew and included, among others, a pump factory, a carton-board mill, a pulp mill and power plants.

The company commissioned an analysis of two business ideas: machining subcontractor or installation and maintenance services? It was decided that both ideas would be pursued. That the company already owned land in Kaarniemi, Kotka, was a definite asset. Regardless of President Mauno Koivisto’s words of warning, Finland was living the hustle and bustle of consumerism, and nobody saw the potential threats in the analysis.

Seppo Lonka was hired as the first long-term foreman: he only retired in April 2009.

The company’s machinery range consisted of four turning machines, to which a new milling machine was soon added.

1984
Busy days

Oiva Sundberg: “Shipyards began to subcontract much of their work, because the need for workforce varied a great deal during the year. This meant busy years for Power Service, and there was no avoiding overtime."

1983
Kotka Power Service Oy

At the Trade Register’s insistence, the word Kotka was added to the company name. The official Trade Register entry date was Oiva Sundberg’s 45th birthday, 7 April 1983.

The company’s first purchases were a new Datsun pickup, a new screw press and two used machines: a drilling machine and a center lathe.

The first customers of Kotka Power Service were Oy Nordshipping Ab (Rauma), Kalaranta Marine Service Ky (Kotka), Oy Wärtsilä (Kotka shipyard), Laivuri Ahti Perheenmies (Kotka), Valmet Oy (Kotka shipyard) and Etelä-Suomen Laiva Oy.

1982
Power Service Oy in business

Chief Engineer Oiva Sundberg first began ship maintenance work on shore as a shareholder in Akiship Oy. The same year he bought his tools and equipment from the company and set up his own business, Power Service Oy, in Kotka.
