Many international buyers search for “Top 10 aluminum die casting companies in Spain” when they start sourcing. It’s a common first step — but high rankings don’t always mean best fit. As a manufacturer with over 20 years of experience in aluminum die casting, we’ve seen how important it is to match the right supplier to your technical and logistical needs, not just pick from a list.
Top 10 Aluminum Die Casting Companies in Spain
Spain has several long-established and mid-sized foundries serving sectors like automotive, lighting, and industrial equipment. Here are 10 companies often referenced in industry directories and search results:
- Fuchosa: A known supplier of aluminum and iron castings, especially for automotive applications.
- Gurelan S.A.: Specializes in hot chamber and cold chamber die casting for aluminum and zinc.
- Inyectometal S.A.: Offers high-pressure die casting services across Spain and the EU.
- Fundiciones de Roda S.A.: A regional casting company serving various industrial needs.
- Industria Auxiliar Alavesa S.A.: Focused on aluminum components for energy and transportation.
- CME San Miguel: Provides die casting and CNC machining under one roof.
- Alunext: Works with aluminum injection and surface finishing.
- Fundiciones Balaguer: Manufactures specialized components including high-precision cast parts.
- Alutecnos: Offers structural aluminum die castings for niche industries.
- Inyectados Alsamar: Produces aluminum die castings with a focus on small-to-medium runs.
These companies are frequently referenced in public directories and search results. This list is for general reference only and does not constitute a recommendation.
Aluminum Die Casting Parts Buyers Should Know
We’ve worked with buyers in Spain and with Spanish-speaking sourcing teams. While Spain has many capable suppliers, there are a few recurring misunderstandings we’ve encountered that overseas buyers should be aware of:
- Tooling ownership terms: Some Spanish foundries offer low initial tooling quotes, but include clauses that limit mold transfer or charge high relocation fees.
- Holiday-related lead times: Spain has many national and regional holidays. These pauses can affect production planning — especially in August and December.
- Language gaps in DFM: While many teams speak basic English, detailed design-for-manufacturing (DFM) discussions often face delays unless the client speaks Spanish or provides annotated drawings.
- Export readiness: Since many Spanish factories mainly serve EU customers, their packing and labeling may not meet longer-haul freight or customs requirements unless specifically requested.

A Spanish Lighting Manufacturer Seeking Better Precision
A mid-sized lighting equipment manufacturer based in Valencia reached out to us in 2024. They were sourcing aluminum housings locally but facing increasing scrap rates — over 4% — due to porosity and surface inconsistencies. Their local supplier explained it was within tolerance, but their LED assembly lines were rejecting units.
We reviewed their part geometry and recommended switching to ADC12 with vacuum-assisted die casting. We also adjusted the gate and vent design during tooling. After three rounds of samples, their defect rate dropped to below 0.8%. They now order 12,000 pieces per batch from us, and we’ve since helped them redesign two more components for better strength and finish.
Compatibility Is More Valuable Than Rankings
In die casting, the best supplier isn’t always the one that ranks high — it’s the one who understands your drawings, speaks your technical language, meets your schedule, and delivers consistent quality. We’ve worked with Spanish companies both as a direct supplier and as a backup option when others couldn’t meet demand.
If your production requires aluminum die casting parts and you’re open to working with a global partner who takes timelines and tolerances seriously, we’re ready to help.
