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.

How lost wax casting works, step by step: pattern waxes, ceramic shells, dewaxing, burnout, pouring, tolerances and the defects to watch for.

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.

Difetti di fusione diagnosticati in base alla loro posizione anziché a supposizioni: porosità da gas e da ritiro, bolle, lacerazioni a caldo e difetti da sabbia, con cause, soluzioni e una tabella di riferimento a 22 righe.

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.

La lega, le dimensioni e le tolleranze determinano la rosa dei candidati. Il volume annuo decide il vincitore. Un confronto a tre tra fusione in sabbia, fusione a cera persa e pressofusione, con i punti di svolta che fanno la differenza.

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.

Training mold makers for digital casting: the CAD workflow, printing process, QC loop, and a practical 12-week plan to upskill your team.
