  • Design For Metal Casting

    Trustbridge helps product developers consider metal-casting requirements as they develop and refine their designs. We bring manufacturing knowledge into decisions about geometry, materials, tooling considerations, dimensional requirements, and the part’s intended use

Bring casting considerations into the design

Metal casting creates practical questions around geometry, material behavior, tooling, and any later machining. Our studio helps you consider these questions during design and identify what needs refinement or further evaluation before moving toward production

Tolerances depend on casting method, alloy, and part geometry

Consider alloy requirements during design.

Material decisions should reflect the part’s purpose and intended casting approach. We help you identify requirements to consider and the material questions that need further evaluation
  • Aluminum Alloys: A356, A319, 6061, 7075, ADC12

  • Steel Alloys: Carbon steels, alloy steels, stainless steels (304, 316, 17-4)

  • Iron Alloys: Gray iron, ductile iron

  • Copper Alloys: Brass, bronze, beryllium copper

  • Nickel-Based Alloys: Inconel, Monel

  • Titanium Alloys: CP titanium, Ti-6Al-4V

  • Zinc Alloys: Zamak 3, Zamak 5, ZA-8


Our team helps optimize alloy selection for strength, thermal properties, corrosion resistance, and cost efficiency.

Materials We Support in Metal Casting
Technologies in Our Metal Casting Network

Different casting processes, different design questions.

The intended process influences geometry, tooling, material choices, and later operations. We help you consider these questions as the design develops.

  • Design for sand casting: Consider wall geometry, draft, parting, core requirements, and machining allowances in relation to the part’s function.
  • Design for investment casting: Consider geometry, section transitions, pattern and shell considerations, dimensional requirements, and any later machining.
  • Design for die casting: Consider wall geometry, draft, parting, ribs, and features that may require slides, inserts, or further process-specialist review.
  • Process-specific review: Identify questions about alloy suitability, tooling, heat treatment, inspection, and validation that require input from the relevant specialists

Industries We Serve

Tell us what the part needs to do, where it will operate, how it interfaces with other components, and what requirements must be met. These inputs help define the design work and the questions that require further evaluation.
