Mustard, Sawdust, and Perseverance – Veikko’s Journey to Becoming an Engineer (1907–1934)

Veikko Olavi Lapinleimu was born in 1907 to Felix Hjalmar (1882–1934) and Helmi Katariina Eskola (1880–1960). He grew up with three siblings: Jalmari (1906), Lauri Johannes (1910), and Liisa Maria (1913).

The family’s tannery, run by Veikko’s father, provided work for the entire household. Yet, as their family grew to four children, Hjalmar and Helmi began dreaming of a new path. They envisioned opening their own leather and footwear shop. Opportunities appeared in several locations, including Pitkäranta on the shores of Lake Ladoga, and in Toijala, where a commercial and residential building along the main road had become available after the death of its owner, August Mäenpää.

Ultimately, Toijala emerged as the winner, because it provided the children with the opportunity to attend secondary school. In 1919, the family made the move there. Hjalmar bought a house at the location where the local pharmacy now stands and establisher Lapinleimu Leather and Footwear, a specia store specializing in high-quality leather goods. Most of the products were produced the family’s factory in Loppi, and as the business expanded, shoes were added to the offer.

However, Veikko Lapinleimu, had no desire to follow the path of his father, grandfather, and almost all the men in the family - he aspired to become an engineer. Part of his motivation stemmed from his independent and headstrong nature, but another significant influence was a childhood hero: the esteemed Mr. Engineer, who had once visited their home for a meal.

Veikko sat in the kitchen, wide-eyed, carefully watching as the engineer calmly ate at the head of the table. The fact that the engineer asked for mustard to go with the bacon seemed miraculous to young Veikko. When the engineer finally left, Veikko devoured almost an entire jar of mustard, tears streaming down his face. When his mother wondered why, Veikko justified it: "The engineer ate it too – and I'm going to be an engineer when I grow up!"

Veikko’s ingenuity did not stop at mustard. While still in middle school, he built his own radio after seeing one at the home of Urho Järvinen, the artistic director of the Hellberg wallpaper factory. His path then led to the Helsinki University of Technology, where he graduated as a diploma engineer in 1932.

He began his career at Höyrypuuseppä Oy in Tampere and later moved to Asko-Avonius Oy in Lahti, where he designed a modern kiln that dried the wood before processing. In the winter of 1934, Veikko travelled to Leipzig for business with Asko-Avonius. It was during this trip that he had a pivotal moment – his introduction to plastics technology and machinery sparked a revolutionary idea: objects could be made from Bakelite without any chipping. This idea stuck with him and continued to develop.

. After five years working in the woodworking industry, Veikko moved on to become a lecturer at the Helsinki Technical Institute. There, he was known as an inspiring and lively speaker, which made him very popular with his students – no one ever nodded off in his lessons.

And so Veikko’s journey continued: from engineer and lecturer to pioneer of the plastics industry and founder of Lapinleimu Oy. It all began with a single spoonful of mustard - and culminated in Finland’s first Bakelite products.

Lapinleimu’s Journey: From Plastics Pioneers to Modern Injection Molding (1935–1984)

In 1935, Veikko Lapinleimu returned from Germany with more than just his suitcase - he brought back a spark of inspiration about the possibilities of plastics, especially Bakelite, which was entirely new and fascinating at the time. Inspired by the machines and materials he had seen at the Leipzig trade fair, he wasted no time. Veikko Lapinleimu wasn't one to wait around. He commissioned a compression molding machine (pictured) - a rarity in Finland at the time - and pressed his first Bakelite product on Good Friday in the kitchen of a house along the main road in Toijala.

Later that same year, Veikko and his brother Lauri founded Taidehartsitehdas T:mi Lapinleimu, which later became Lapinleimu Oy. This was Finland’s second plastics factory. In the early years, the business was managed by Lauri, as Veikko was still working at Asko-Avonius and later as a lecturer until 1946. Nevertheless, Veikko was continuously involved in product design.

Veikko Lapinleimu was not only an engineer but also a visionary - he saw plastic not just as a material – but as a tool for the future. The product range expanded from Bakelite knobs and handles to include medicine bottle caps and pipe stems. Due to limited space, an additional 5 × 15-meter workshop was built in the backyard, and the company hired its first employees.

Although the Winter War temporarily halted Lapinleimu’s operations, during the Continuation War (1941–1944) the company was closely involved in defense efforts. Lapinleimu Oy produced Bakelite components for the Finnish Defence Forces, including grenade fuzes, release pins for aerial bombs, protective caps for ammunition, and parts for the triggering mechanisms of ice mines - tested, among other places, on the ice of Nahkialanjärvi Lake.

Veikko Lapinleimu also developed a specialized mortar for firing stacked charges. Its functionality was tested in the Hauenkuono area in the presence of army personnel - and the event left a lasting impression on local children, who watched curiously from behind a fence as the soldiers, clad in gray, carried out their work.

After the war, Lapinleimu Oy continued to grow: production facilities expanded, and machinery advanced as demand for plastic products increased. The modest Bakelite factory, which had long been run as a family business, evolved through hard work into an internationally recognized specialist in ventilation technology.

Veikko Lapinleimu was a respected and compassionate leader who treated all employees equally, regardless of social status or political orientation. Even on a bad day, Veikko made sure to greet every single employee personally, ensuring no one was overlooked. This approach helped him build close and trusting relationships with his staff. Veikko’s innovation and perseverance were apparent in both his management style and product development. He had strong confidence in his abilities and motivated those around him to succeed.

A new chapter began in 1977 when a young engineer, Leo Koskinen, joined Lapinleimu's plastics department. He brought fresh energy, enthusiasm, and a broad perspective on the use of plastic in industry. In his work, he became captivated by plastic's diverse possibilities and fully dedicated himself to the field. Over seven years, Koskinen gained a deep understanding of plastics production and its business potential. This led to a significant decision in 1984: Leo Koskinen purchased Lapinleimu's plastics business and founded a new company, Leomuovi Oy.

Lapinleimu’s Legacy Lives On in Leomuovi (1984–2001)

The deal was sealed with a handshake. Leo Koskinen, who had been the head of Lapinleimu’s plastics division, purchased the department and used it as the foundation to establish Leomuovi Oy—a company that honored Lapinleimu’s valuable legacy while resolutely looking to the future. Leo aimed to combine traditional plastics expertise with the latest technology and to build genuine partnerships with customers. The machinery, employees, and traditions were transferred to Viiala, where Leomuovi began operations in 1984.

In its early years, Leomuovi exceeded expectations. The machinery was modernized, production facilities expanded, and revenue grew. The company's product range included a large number of technical plastic components, most of which were subcontracted, but it also had its own products, such as the star and ball knobs developed for industrial use.

During the 1980s and 1990s, Leomuovi focused resolutely on developing injection molding technology and expanding its production capacity. The company responded to the growing needs of the Finnish industry and strengthened its reputation as a reliable and flexible partner.

The challenging 1990s brought increased competition in the plastics sector and technological upheaval, but Leomuovi remained at the forefront of development. It adopted new production methods and deepened its customer relationships. These strategic choices ensured that the company stayed strong and competitive, even in a rapidly changing business environment.

On May 15, 1995, the young and enthusiastic Sami Rantala joined Leomuovi as a technical advisor, handling both supervisory and technical tasks. At that time, no one could have predicted that Sami would later become a central figure and driving force within the company.

The Duo Behind the Growth – Risto and Sami Lead Leomuovi Forward (2001–2025)

Leo Koskinen began dreaming of retirement and realised it was time for a new owner – especially as the factory was in better shape than ever. The change in ownership took place in 2001, with Pasi Mönkö and Risto Kalliainen, both with backgrounds in mechanical engineering, taking over.

In 2005, Sami Rantala stepped into Mönkö’s shoes, bringing his extensive technical expertise into the management. Together, Risto and Sami formed a dynamic leadership team whose strategic vision and technical knowledge strengthened Leomuovi’s position as a competitive and reliable partner for the Finnish industry.

A quarter of a century later, Leomuovi has established itself as a true professional in its field. Its expertise is evident in a high-quality, extensive product range and an impressive customer base. Under the leadership of Risto and Sami, the company has grown both organically and through strategic acquisitions.

Significant milestones for Leomuovi include the acquisition of WM-plast Oy in Kankaanpää in 2018 and VS-Automaatio Oy in Uusikaupunki in 2021. These acquisitions enabled factory operations to continue in both Kankaanpää and Uusikaupunki in addition to the Akaa facility. Most recently, in 2024, Leomuovi further strengthened its position by acquiring MP-Plast Oy, expanding both its product range and production capacity. This move also opened new opportunities for eco-friendly innovations.

With a blend of tradition, technological expertise, and strategic growth, Leomuovi has become a prominent player in the plastics industry, well-equipped to tackle future challenges. Operating in multiple locations, the company enhances production flexibility and reliability, ensuring timely delivery to customers even in extraordinary situations. This allows Leomuovi to harness the benefits of a large corporation while maintaining the agility and customer-centric approach of a smaller business.

Leomuovi’s story is not just about machines, production halls, or acquisitions. Above all, it is about people—with will, skill, and passion. It is the spark that began with Veikko’s spoonful of mustard, passed down through generations, and carried forward by new owners, employees, and customers.

Under the leadership of Risto and Sami, Leomuovi is more than the sum of its plastic parts: it represents reliable quality, innovation, and continuous development. With this foundation, Leomuovi continues toward the coming decades - it does not merely follow developments; it shapes them itself.
