Erikoisvalu Oy – Metal Castings for Demanding Needs
Erikoisvalu Oy is a Finnish foundry specialized in producing high-quality metal castings for industrial clients, communities, and private customers. We work with aluminium, copper, brass and bronze, casting everything from individual components to small production series and prototypes.
We are located in Mäntsälä, Southern Finland, and have served satisfied customers since 1977.
Our quality management system is certified according to the ISO 9001:2015 standard. This ensures that our operations meet international quality requirements and that we continuously improve our processes for the benefit of our customers.


What we do
- Prototypes for product development
- Small series production (1–100 pcs)
- Single custom parts, also without drawings
- Restoration and replacement parts, e.g. for vehicles and machinery
- Sculptural and artistic castings
- Functional components for machines and technical applications
We specialize in sand casting, which enables fast and cost-effective production of one-off parts or limited batches without expensive tooling or large volumes.
Why work with Erikoisvalu Oy?
- Decades of experience in complex and demanding casting work
- Fast decision-making and direct communication – we keep it simple
- Ability to work with tight schedules and incomplete specifications
- Focus on quality, precision and long-term functionality
We are especially suited for projects where standard solutions don’t apply, or where speed, flexibility and know-how matter more than mass production.
