The most significant up-front cost is the creation of the custom injection mold itself, which is a durable, high-precision tool designed for high-volume production. An injection mold can cost anywhere from $10,000 to $100,000+, depending on the part’s size and complexity. Because this process is optimized for large quantities, if your project only requires 1,000 pieces or fewer, it may not be the most cost-effective solution. This investment is designed to produce thousands or even millions of identical parts at a very low per-piece cost over the life of the project.
