The short answer If the part moves against something, carries a load at temperature, or meets seawater, it is bronze. If it is a fitting, a housing, a valve body or a decorative item in a dry environment, brass will usually do the same job for less money and machine more easily. The trap is […]

The mold-making operation itself: pattern allowances by alloy, sand and binder targets, ramming and mold hardness, gating and riser design, vents, closing, pouring temperatures and shakeout – plus when a printed sand mold removes the pattern entirely.

Cómo funciona la fundición a la cera perdida, paso a paso: ceras para modelos, envolventes cerámicas, descerado, combustión, colada, tolerancias y defectos a tener en cuenta.

Industrial SLS pricing bands, coated sand and PSB wax consumables, laser time and a per-part worked example, with a worksheet for filling in your own local costs.

Defectos de fundición diagnosticados según su ubicación, en lugar de basarse en conjeturas: porosidad por gas frente a porosidad por contracción, burbujas, roturas en caliente y defectos de arena, con sus causas, soluciones y una tabla de referencia de 22 filas.

The sand casting process from pattern to finished part: six steps, five molding methods compared, sand and binder selection, gating and riser design, and pattern options.

A foundry audit that fits in one visit: the documents to request, what to watch on the floor, a 25-point scorecard, and the findings that should end the visit.

Alloy, size and tolerance set your shortlist. Annual volume picks the winner. A three-way comparison of sand, investment and die casting, with the crossover points that decide it.

Where 3D printing fits into investment casting: printed wax patterns, rapid tooling from printed masters, tooling-free prototyping, and an honest look at what it does not change.
