Foundry patterns in Cantabria, Spain

At Talleres Nocu we have been making foundry patterns since 1956 at our facilities in Guarnizo (Cantabria, Spain). We work for ferrous and non-ferrous foundries with patterns in wood, resin and polystyrene, from small parts to very large patterns, under an ISO 9001:2015 certified quality system.

What is a foundry pattern?

The pattern is the replica of the part that the foundry uses to form, in sand, the cavity into which the metal is poured. The geometry and quality of the final casting depend on its accuracy. Together with the pattern we make the core boxes needed for the internal cavities.

Engineering department

We design the pattern in NX from the customer's drawing or 3D file, in STEP, IGES or STL format. CNC machining is programmed with TEBIS.

Flexible manufacturing

We choose the method for each pattern: manual work by highly experienced patternmakers, 5-axis CNC milling, 3D printing (FDM up to 1150 × 800 × 700 mm and large-format LFAM up to 2500 × 1300 × 1000 mm) or a combination of these techniques.

Inspection and finishing

Every pattern is scanned with a tracker-based 3D scanner, with no need for targets, and compared with the original CAD using a colour deviation map. The final finish is adapted to each customer's needs.

Patterns for metal casting

The patternmaker makes the foundry pattern and the core boxes; with them, the foundry prepares in sand the part to be cast. At Nocu we handle the engineering and manufacture of foundry patterns: we adapt to the way each foundry needs the pattern.

Materials for foundry patterns

We choose the pattern material according to the production run, the size and the type of casting: wood, resin or expanded polystyrene. Machining is done by 5-axis CNC milling.

Sectors

We make patterns for the marine, wind energy, valve, pump, railway, stove and other industrial sectors, with customers in 9 countries.
