Iron Foundry

Excellence in Cast Iron since 1936

With 88 years of experience and an exclusive industrial unit for casting, we have the capacity to produce grey cast iron parts of various alloys up to 500kg.

Specializeds in lamellar grey iron, and Ni Resist.

Lamellar grey iron

(EN-GJL-200, EN-GJL-250 and EN-GJL-300)

Lamellar grey iron: Lamellar grey cast iron alloys are so called due to the presence of graphite in the form of lamellae in their microstructure, and parts made from these alloys are used in the cast state for many purposes. From a mechanical point of view, the graphite lamellae act like small cracks, giving the material good machinability, as they favour the detachment of swarf during the machining process.

Nodular grey iron

(EN-GJS-350-22, EN-GJS-400-15, EN-GJS-400-18, EN-GJS-400-18LT, EN-GJS-450-10, EN-GJS-500-7, EN-GJS-600-3, EN-GJS-700-2 and EN-GJS-800-2)

Nodular grey iron The structure of this family of alloys is obtained directly from the casting of grey cast iron by adding small quantities of certain chemical elements, such as magnesium, which cause graphite to precipitate in the form of nodules. These metallic materials have good wear resistance, a high modulus of elasticity and resistance to fatigue. They are also characterised by better resistance to shocks and static stresses when compared to lamellar graphite grey cast irons, but have a lower damping capacity and lower thermal conductivity.

Ni Resist

(EN-GJLA-XNiCuCr15-6-2)

Ni Resist: This family of grey cast iron alloys has an austenitic structure and a high nickel content, and is known for its exceptional resistance to corrosion at high temperatures. These alloys are used in applications that require corrosion resistance, resistance to high temperatures and wear resistance, such as components for the chemical and oil industries.

Geometries, materials and finishes 

Green sand moulding stands out as a traditional casting technique, valued for its adaptability and versatility. This method, which involves using sand to form the mould, allows for efficient handling and the production of parts with precise contours. The ability to regenerate the sand used, combined with the economy of the process, makes green sand moulding a sustainable and efficient option for various applications.

On the other hand, the cold box machining process, a more recent technique, revolutionises the production of parts with complex geometries. FELINO uses resins to bind the sand under room temperature conditions to produce highly precise and resistant taps, which are essential for obtaining complex, high-quality parts.

These approaches make it possible to carry out various foundry projects and guarantee a range of solutions that FELINO makes available to its customers.

Production capacity for small, medium and large series

Advantages of Sand Casting

Sand casting is notable for its ability to produce large, complex parts while maintaining dimensional accuracy and a good quality surface. It is highly scalable, suitable for both small production runs and large volumes.

BMD Automatic Moulding

BMD Automatic Moulding is a technologically advanced process that uses a sand moulding system with computerised numerical control. This method stands out for its efficiency and precision, making it possible to produce highly complex parts, even in high volumes.

BMD technology promotes greater uniformity between the parts produced, thanks to the precision of the moulding process. In addition, the automation involved makes it possible to significantly reduce cycle times and the labour required, which results in significant gains in productivity and efficiency.

This method is especially suitable for producing parts with complex and detailed geometries that would be difficult or time-consuming to produce using traditional moulding methods. The flexibility of the BMD process allows us to produce parts of various sizes and shapes, from small to large, and in a variety of materials, including grey iron, nodular iron and Ni Resist.

This process allows us to respond to a wide variety of customer needs and constantly maintain high standards of quality and efficiency.

At FELINO, quality is our priority. As a benchmark in the casting of highly precise, complex and critical metal parts, we endeavour to meet and exceed our customers' expectations. Our dedication to excellence is reflected in every part we produce and in the service we provide to our customers.
