Mika Korhonen, Polarteknik’s Business Development

Polarteknik, based in Finland, manufactures reliable, sustainable, high-quality interior door systems for the world’s leading train manufacturers. As you can imagine, seals play a significant role in their door solutions!

Polarteknik and FinnProfiles have collaborated since the early 2000s. Around the same time, Mika Korhonen began working at Polarteknik, where he currently serves as the company’s Business Developer.

We met Mika at Polarteknik’s headquarters in Huittinen and asked a few questions about collaboration.

First, could you tell us a little about Polarteknik’s products?

“Well, we produce approximately 4000–5000 train door systems annually, primarily delivered to Central Europe. The systems can be single—or double-leaf doors or telescopic, curved, and hinged doors. Additionally, we manufacture gangway cassettes, toilet, and cabin doors, each with its own specific requirements,” Korhonen lists.

“Seals contribute to passenger comfort and are associated with many safety aspects.”

How significant role do seals play in your products?

“Each of our door systems contains several meters of seals, so in that sense, seals are a significant part of the structure of our products. Additionally, they contribute to passenger comfort and are associated with many safety aspects, in case of fire and smoke, for instance, that we must consider.”

“The collaboration works extremely well!”

How has the collaboration with FinnProfiles gone so far? What do you particularly appreciate about it?

“The collaboration works extremely well! The quality is good, and deliveries are on time. On the other hand, we can rely on the fact that our seals are manufactured according to all required standards. In fact, FinnProfiles was one of the first companies to meet our needs when Europe transitioned from national material standards to unified standards.”
