Tooling costs are primarily influenced by the part's shape, number of cavities, slider or lateral structure, dimensional tolerances, mold material, and estimated lifespan.

The unit price of a part is typically affected by the following factors:

• Raw material type and price.
• Part weight and material utilization rate.
• Production quantity.
• Forming and sintering difficulty.
• Dimensional tolerances.
• CNC machining, grinding, or shaping requirements.
• Heat treatment, electroplating, oil immersion, or coating requirements.
• Inspection, packaging, and traceability requirements.

Therefore, parts with the same external shape can have significantly different costs due to variations in performance, tolerances, and annual demand.
