Tailored Machine Shop Expertise — from Ships to Agricultural Machinery

Our core operations consist of machine shop services and contract-manufactured products. Among other things, we service and repair equipment and manufacture fireplace products to custom specifications. We provide first-class service related to scrap platforms, recycling containers, waste skips, agricultural machinery, and subcontracting for various industries.


Tarvasjoen Konepaja is a small and agile family business that takes on even the biggest challenges. We serve business customers nationwide from our base in Lieto. Decades of experience in the metal industry have taught us the most important lesson: every customer and every need is different. That's why we don't do assembly-line work — we tailor every solution to the situation.


We know the market inside and out. We know which materials, methods, and structures each application requires, and most importantly, we know how to apply this knowledge to your specific needs. As a customer, you don't necessarily need to know the exact technical solution in advance. Just tell us your problem or need, and we will design and implement the solution for you.

Four reasons to choose us

Agile Operations — Even on Tight Schedules

Our size is our strength. In a small organisation, decisions are made quickly, changes are responded to immediately, and every customer receives personal service. Yet our capacity and expertise are sufficient for even the most demanding projects, and we deliver products and services throughout Finland.

Tell us the problem, we'll find a solution

Many customers have a clear need but no ready plan yet. That suits us perfectly. We help from the brainstorming stage: we map out the need, design the implementation, and manufacture the end product on a turnkey basis. You get one partner who takes care of everything.

Adaptability Is Our Core Competence

We adapt in many directions, and you get everything you need from one workshop. We manufacture individual special parts, small production runs, and large subcontracting batches. We know how to adapt existing structures for new purposes and design entirely new solutions. Adaptation is not an add-on service for us — it's our way of working.

Subcontracting and design

We are not just a manufacturer. We serve as a reliable subcontracting partner for many companies and also offer design services. You can outsource a single work phase or an entire part of the production chain to us — we'll agree together on what works best.

Over 60 Years of Machine Shop Expertise

The story of Tarvasjoen Konepaja Oy began in 1962, when Leo Mynttinen founded Killalan Puutyö in Tarvasjoki. In the early days, the company manufactured tractor safety cabs, pole peelers, and potato harvesters.


In 1976, the company specialised in bakery and food industry machinery and was renamed Tarvasjoen Konepaja Ky. Leo's sons Jaakko and Matti continued their father's work, and in 1982 Jaakko took over as head of the company.


A new chapter began in 1994 when the import of TMR (total mixed ration) feed wagons started. Jaakko focused on the import and maintenance of SEKO TMR feed wagons. In 1999, Matti's son Mika Mynttinen joined the company's management, bringing expertise in fireplace door manufacturing and metal industry subcontracting.


The company was incorporated as a limited company in 2013. Today, this third-generation family business serves customers nationwide — with the same agility and craftsman's precision that has been there from the very beginning.
