  • Design for urethane and silicone casting.

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

Bring casting considerations into the design

Casting creates practical questions around geometry, mold design, material behavior, and surface requirements. Our studio helps you consider these questions during design and identify what needs refinement or further evaluation before moving toward production

Casting tolerances

Define the dimensions and surfaces that matter.

Start with the part’s function, interfaces, and fit requirements. During design review, consider how geometry, material behavior, mold construction, and the intended casting approach may affect those requirements.

  • Critical features: Identify mating surfaces, holes, snap-fits, and dimensions that influence fit or function.

  • Geometry and tooling: Review wall geometry, parting lines, undercuts, and demolding questions that may require refinement or process-specialist input.

  • Finish and validation: Clarify appearance, texture, color, and surface-function requirements, along with any inspection or testing needs

Consider material requirements during design.

Material decisions should reflect the part’s purpose and intended casting approach. We help you identify the requirements to consider and the material questions that need further evaluation.

  • Rigid Urethane Resins (Thermoplastic-Like):

    • ABS-Like: High impact strength for snap fits. 
    • PC-Like (Clear): Optical clarity for lenses. 
    •  PP-Like: Flexible fatigue resistance. 
  • Elastomeric & Rubber Casting :

    • Medical-grade silicone

    • Food-grade silicone

    • Soft-touch applications

    • High-durometer silicone

    • Heat-resistant silicone

Materials We Support in Urethane and Silicone Casting
Technologies in Our Casting Network

Different casting approaches, different design questions.

The intended casting approach influences geometry, tooling, and material choices. We help you consider these questions as the design develops.
  • Masters and molds: Consider how the master’s geometry and surface will relate to the mold and finished part. Review parting, draft, undercuts, and access for demolding.
  • Urethane casting: Consider resin behavior, wall geometry, dimensional requirements, and the interfaces important to the part’s intended use.
  • Silicone components — scope to confirm: Consider flexibility, wall geometry, interfaces, demolding, and the material questions relevant to the application.

  • Process-specific review: Identify questions about vacuum or pressure casting, inserts, or combined materials that need review with an appropriate specialist.
