Frequently Asked Questions

How much do custom molds cost?

Custom mold costs vary significantly based on size, complexity, and material. Prototype tooling using wood or polyurethane typically ranges from $1,500 to $5,000 and can be produced in just a few weeks. Production aluminum molds generally cost $5,000 to $25,000+ depending on part size and detail requirements. Our approach allows you to validate your design with low-cost prototype tooling first, then invest in durable aluminum production molds once the design is finalized. We provide detailed quotes based on your specific requirements and help you select the most cost-effective tooling strategy for your project.
