At the Port of Varna, our stainless steel pump valves and ship parts ensure that cargo vessels maintain operational efficiency even in corrosive saltwater environments.
In the Danubian Plain, Bulgarian farmers are moving towards high-tech agricultural machinery. Our lost-wax agricultural castings provide the precision needed for modern harvesters.
As Sofia expands its metro and commercial districts, our custom alloy castings support the heavy-duty machinery building the next generation of Bulgarian landmarks.
The global trend toward Nearshoring has put Bulgaria in a unique position. European companies are looking for "Satellite Manufacturing" hubs. We support this by providing one-stop precision manufacturing—from mold design to final surface treatment. Our Carbon Neutral Casting initiatives and material science breakthroughs in alloy steel are designed to meet the upcoming EU ESG (Environmental, Social, and Governance) requirements, making us a future-proof partner for any Bulgarian procurement officer.
Our facility is equipped with internationally advanced automated casting production facilities and comprehensive physical/chemical analysis labs.
Typically, mold development takes 15-20 days, and production takes 25-30 days. Shipping to the Port of Varna or Sofia via rail/sea takes approximately 30-40 days. We also offer air freight for urgent project milestones.
Yes, all our products for the Bulgarian market are manufactured under TS 16949 and ISO 9001 certifications. We provide full material certifications and dimension inspection reports with every shipment.
Absolutely. Our engineering team can work with CAD, SolidWorks, and Pro/E files to create custom molds that meet your specific mechanical property requirements.
We provide a unique combination of "Scale Economy" and "Precision Engineering." Our cost-per-unit is significantly lower than domestic EU foundries, without compromising on the tight tolerances required by high-tech industries.
