Bardane provides design and engineering assistance with 3D CAD and SLA rapid prototyping capabilities. Through early involvement at the development stage, Bardane is able to integrate design considerations and options with customer demands, and provide prototypes of zinc or aluminum die castings at the preconstruction tooling stage.

- Radius all corners where possible. Resistance to metal flow is decreased through radii as is the tendency to drag and bend at sharp corners. The outer skin is the hardest (strongest) casting area, and by radiusing, the skin remains intact.
- Allow maximum draft where practical. This assists casting release from the mold, and as with radiusing, bending and tearing are minimized.
- Keep wall thicknesses as uniform as possible. This enhances metal flow by avoiding pressure drops – going from thick to thin to thick surfaces – during the injection cycle. Pressure drops inhibit metal flow, promote backfilling, and result in cold shut and porosity.
- Casting design must be kept practical with the casting process. Dimensions across the parting line and dimensions across moving die members (cam actions, hydraulic pulls, etc.) must be specified given that such areas are the most difficult to maintain in die casting. Proper engineering and die construction minimizes problems associated with moving die members.
- Keep tolerances practical and essential as is necessary.
- Keep machining stock to a minimum in order to avoid porosity openings.
- Cored Holes
- Aluminum: min. .080
- Zinc: .040
- Cast Threads
- Keep in class A
- Allow flats at parting line if possible
