The roots of Lahti Glass Technology date back to 1908 when factory producer Mr. P. Kuivalainen established a machine shop in Lahti. The workshop repaired machines and manufactured iron beds. The operations expanded rapidly with the iron and metal industry in Lahti (nowadays Raute Oy Corporation). As Finland started to favor wooden beds, the demand for iron beds was no longer there.


Iron bed production was replaced by scales in 1914 and the factory began to develop weighing technology know how. In this case a new company called Lahti Vaaka Oy (Lahti Scale Ltd) was established and the weighing history of the company was formally established. The scales were initially made mainly for the use in domestic households and shops. Since the 1930s, the company has developed new types of scales for industrial and warehouse use, as well as for weighing vehicle loads. The importance of a customer based approach was already realized at that time: the factory produced scales according to the individual uses of its industrial customers.


In the 1960s, major investments were made in the product development of scales. The company was a pioneer and developed a photoelectric code sensor. The first electrical scale was delivered in 1964. Also, as the volume of deliveries grew and a wider range of deliveries to plants was made, for example to ready-mix concrete and glass factories.


The demand for mechanical scales shifted more to electrical scales and the need for automation increased. In 1975, the company started its own electronics factory.


The company was internationalized in the 1980s. Demand for weighing and dispensing, handling of bulk materials and related automation was also in demand abroad and the company's position as a supplier of complete process entities and plant deliveries was strengthened. The aim was to control the entire measuring chain for industrial weighing, from the components to the automatic control of the process. A mass and power measurement laboratory and a material laboratory were built. The main customer groups were the building materials industry, the steel industry, the chemical industry and the food industry. Turnkey deliveries were started for the glassworks factory's raw material plants, mortar and dry mix industries and for the metallurgical industry.


In 2004, Raute gave up the weighing business. The company continued its business under the name Raute Precision. The management became the company's owners, together with an external private equity investor. The name of the company was changed to Lahti Precision Oy in 2007. Three business areas were formed within: glass industry, dry mix industry and industrial weighing.


In 2007 the company changed its name from Raute Precision Oy to Lahti Precision Oy since Raute was no longer involved in the company.


In 2011 the equity fund sold its shares to second stage investor Verdane Capital from Norway. The aim was to grow the value of the company and seek profitable exit.


In 2018 the owners of the company sold the Glass Business Division to Zippe Industrianlagen GmbH. All former employees of the Division were transferred to the new company as old employees.

The roots of the company trace back to 1914, when the first scales were manufactured. Decision to go into the glass batching plant business is more than 30 years old and the reference list has more than 200 major deliveries to the glass melting industry. Lahti Glass Technology is now proud to be part of ZIPPE group and continues to serve existing customers and new ones in selected sectors and geographical areas.
