SERFUNSA, S.A.

About us

Serfunsa is a Mexican company specialized in the formulation, design, and manufacturing of chemical solutions for the metal casting industry. Since our foundation in 1977, we have worked closely with foundries across Mexico, supporting their processes with reliable products, technical expertise, and customer-oriented service.

For more than four decades, Serfunsa has built long-term relationships with both production and jobbing foundries, helping them improve casting quality, reduce defects, and achieve consistent results under real production conditions.


Engineering Chemistry with Practical Experience

Our strength lies in combining careful chemical formulation with hands-on foundry experience. Every product we manufacture is developed using modern formulation methods, high-quality raw materials, and strict quality control procedures.

Serfunsa designs its solutions to perform reliably across different alloys, sand systems, and molding processes. This approach allows us to adapt our products to a wide range of foundry environments, including iron, steel, aluminum, lost foam, and permanent mold casting operations.


Manufacturing and Quality Commitment

Serfunsa operates ISO 9001 certified manufacturing facilities located approximately 150 miles south of the Texas border. Our strategic location allows us to serve customers efficiently throughout Mexico while maintaining fast response times and dependable supply.

Quality is built into every stage of our operation, from raw material selection to final product delivery. Our internal laboratory supports continuous improvement, formulation development, and performance verification, ensuring that our products meet both technical and operational requirements.


Customer-Oriented Technical Support

At Serfunsa, we believe that effective solutions go beyond the product itself. Our technical team works directly with customers to provide free laboratory services, defect analysis, and on-site technical assistance.

By collaborating closely with foundry personnel, we help identify root causes of casting defects, optimize application methods, and fine-tune formulations when needed. This hands-on support allows our customers to achieve measurable improvements in process stability and casting quality.

Our long-standing presence in the market reflects our commitment to reliability, technical competence, and continuous improvement. Many of our customer relationships span decades, built on trust, performance, and consistent support.


Looking Forward
