Injection Molding Cost Calculator

Injection molding cost = mold cost + per-part cost. Molds start around ฿10,000 in Thailand; per-part cost drops fast with volume, making molding cheaper than 3D printing above ~1,000-2,000 pieces.

Mold cost

Simple prototype molds from ฿10,000; production molds scale with cavities and complexity.

Part cost

Material + cycle time per shot; from ฿8 at 1,000+ pieces.

Cavity count

More cavities = higher mold cost, lower per-part cost at volume.

Break-even

Usually 1,000-2,000 pieces vs 3D printing; lower vs CNC for simple parts.

Worked example

Simple part: mold ฿15,000 + ฿10/part at 2,000 pcs ≈ ฿17.5/part all-in.

Tooling takes 3-5 weeks; production lead time 10-15 days after tooling.
