Alsiva Oy is one of Finland’s primary contract manufacturers of aluminum and zinc die-cast components. Headquartered in Lehmo (Kontiolahti), the company has operated for over three decades and forms part of the family-owned Ouneva Group. With a workforce of over 70 professionals, Alsiva manages the entire production cycle from component design and mold engineering to fully assembled products.

Alsiva operates an automated foundry with robotized production cells, supported by internal recycling systems that recover and re-melt aluminum runners and overflows. In addition to high-pressure casting, Alsiva offers vacuum die casting to satisfy rigorous structural and pressure-tightness requirements.

Quality control and testing capabilities on site include real-time X-ray inspection, coordinate measuring machines (CMM), and automated leak testing.
