What to confirm before you release an order
Which files to send and in which format, how long each process takes, the six variables that set unit price, how your drawings and intellectual property are protected, and which documents ship with finished parts. Thirty-three questions are answered on this page. Where a figure belongs to a published standard, this page links to the table that maintains it rather than restating it.

Start with the decision you are actually making
Four questions decide whether an order happens. Each one below gives you the short answer, and then a link to the page that covers the detail in full.
Scope
Can you make my part?
- Send the model and we answer with a manufacturability check, not a price alone.
- General tolerances follow ISO 2768 unless your drawing states tighter.
- If a feature cannot be held at the price you expect, we say so before the order.
