years of expertise
During the past decades we have gained all the knowledge and dexterity we can proudly offer to our clients around the globe. Cutting edge pre-production technologies as well as 3 types of foundries and variety of advanced finishing works are the reasons we will very likely meet your demanding requirements.
Future belongs to aluminium
We believe that aluminum is a metal that now has, and in the future will have, an even greater share of components without which industrial production and technology can not sustain.
That is why we use the latest production technologies that are environmentally friendly and we invest in the development of the company so that we can provide our customers with all the services (from the design of the shapes to any surface treatment or inspection) that are necessary for the proper functionality of the product.
History we are proud of

Aluminium age
The company expanded its business activities by starting a foundry specialised in sand casting of aluminium products.
2000–2007
ISO certification
The foundry expanded its activities by casting aluminium products into metal moulds and also by providing other technologies, such as impregnation, heat processing of castings and sub-assemblies. Certification for ISO 9001 and 14001. The Energo Division continues building boiler rooms and other units in the area of heating plant industry.
2008
Foundry expansion
Construction of new sand casting foundry for production of heavy and large castings. The Energo division concentrates on the sales of Nivolair heating units, Oilon burners and Kamstrup energy meters. As far as the construction business is concerned, the company specialises in the designing and construction of power centres.

High quality we strive for
We meet the standards of quality management system for casting aluminium alloys into sand moulds, metal moulds and low-pressure moulds. We are also SVTI certified which means we are an approved supplier of products for high-voltage industries.
Environment is essential For all of us
We want to have a healthy environment around us, so we only use ecological mixtures and production materials. When introducing new technologies, we take care not to have a negative impact on the environment. Our long-standing certificates and developed technologies declare the success of our efforts.
Cast locally, export globally
78 % of our production is exported to the world. That is the proof we are able to meet the highest standards no matter if it is for the markets within European Union, North or South America or Eastern countries.
