A.

Yes, we provide prototype through full-production molding services. Production runs have a $150 setup fee, which is waived when parts are ordered with a new mold.

Q.
What are Fathom's payment terms?

A.

A 50% deposit is required with your purchase order, with the remaining balance due upon sample approval. Production runs require prepayment, and the setup fee may be waived when ordered with tooling.

Q.
Can Fathom help select the right plastic material?

A.

Yes. While final material selection is the customer’s choice, we provide guidance and a searchable materials list based on performance characteristics such as impact resistance or UV stability.

Q.
Can I receive material or part samples?

A.

As a custom mold manufacturer, we strictly protect our customers’ intellectual property, so we do not stock materials or distribute sample parts.
