Why is tooling so much money?

Tool and die making is literally designing and building a “negative” imprint of the cast part while holding very close net tolerances. The tool is reusable (a one-time investment) and often capable of lasting the lifetime of the part. Wax injection does not cause wear and tear on the mold.

Why am I charged for a first article?

This is in order to qualify the tooling. In other words, to guarantee the resulting part is both dimensionally and geometrically correct.

Can I skip the samples and first article process?

Skipping the samples and first article process is not recommended. Financial responsibility for parts produced as a product of the tool (good or bad) falls to the customer.

What is the difference between a weldment and investment casting?

A weldment is a part consisting of sections welded together to create a final component. While often very labor intensive, a large portion of the part’s quality is only as good as the welder. On the other hand, investment casting can manufacture the part in a single process (without welding), which reduces labor hours and costs.
