Plastic Injection Mold Cost Analysis and Breakdown

Mold costs depend on many factors and can be analyzed by the following key elements:

1、Material Cost

Steel grades, treatments etc. account for 15-20% of total cost.

2、Machining Cost

Rough, finish CNC machining of mold makes up 35-45% of cost.

3、Component Parts

Standard components like guide pins, bushings etc. take up 8-12% cost.- Surface Finishing

4、Polishing, texturing etc. forms 10-15% of mold price.

Mold Base – Standardized bases constitute 15-20% of total cost.

5、Design Overheads

Engineering time for CAD/CAE work makes up 10-12% of expense.

6、Assembly & Testing

Assembly, tool proving, documentation takes up 5-8% cost.

7、Contingency

 Unanticipated reworks or changes entail 5-10% cost risks.

Typical cost range is $45 – $95 per cubic inch for custom injection molds in China. Smart design and organized procurement can optimize total mold costs.
