Injection Molding Cost Estimator

Get an instant price range for your plastic injection-molded part. Enter material, part weight, annual volume, mold cavities and part size — no drawing required for a first estimate.

Part Details

Rough inputs are enough for a preliminary estimate.

Select your part's material — high-temp and engineering grades supported.

Enter your part's weight in grams — or upload a 3D file below to auto-calculate it.

What Drives Injection Molding Cost?

Four inputs determine most of the price — here is how each one moves it:

Material

Resin prices span from about ¥9/kg for commodity grades (PS, PE) to ¥800/kg for PEEK. High-temperature plastics such as PEI, PSU and PPS cost far more but handle heat, chemicals and demanding applications.

Part weight

A heavier part uses more resin and a longer cooling cycle, so both material and machine-time cost rise together.

Cavity count

More cavities cut the unit price per part but raise mold cost — 2, 4 or 8 cavities share one mold base and split the cycle time.

Part size

Tooling cost scales with projected area and height. Typical injection molds range from about ¥12,000 for a small 2-cavity tool to ¥115,000 and up for large multi-cavity tools.
