We offer four different inspection options for our injection molding and urethane casting services. The inspection options are described in more detail below. For an example of a Xometry dimensional inspection report with a correlated ballooned print, please refer to our Sample Inspection Documents page.
Inspection Options
Standard Inspection: QC will verify that the part material, features, and finish are in accordance with the part requirements specified in the quote, CAD file, and/or print. If no dimensional print is provided with a part, QC measures to Xometry's Manufacturing Standards on dimensions they deem critical, such as overall size, holes, and depths. If a dimensional print is provided, QC will verify up to 20 dimensions they deem critical. Documentation will not be shipped with your parts.
First Article Inspection Report (FAIR AS9102 or Equivalent): QC will perform a First Article Inspection per the requirements specified in SAE Aerospace Standard (AS 9102) documentation (or equivalent). The purpose of the First Article Inspection is to provide objective evidence that all engineering design and specification requirements are properly understood, accounted for, verified, and documented.
QC will maintain a quality record for customer review of accountability and planning, for performing periodic surveillance and audits to verify conformance, for evaluating root cause and corrective action for any non-conformances, and for problem investigations. A dimensional report with a correlated ballooned print will be shipped with your part(s). Random sampling is based on ANSI/ASQ Z1.4 Level II to an Acceptance Quality Level (AQL) of 2.5%. A customer-specified dimensional print is required for a First Article Inspection. We will build the full lot and do the FAI form at the final QC treating this lot like the first Article. If you want a 1 part and stop for approval, please select custom inspection. The number of inspection points is subject to the applicable 100 maximum. Greater quantities require a Custom Inspection and additional charges.
Source Inspection: A Source Inspection audit is an inspection of purchased products and process records at the supplier's premises to verify compliance with requirements before shipment to the customer. A Source Inspection can include but is not limited to requirements review, specification compliance, and a quality review of the manufacturer. A source inspection will be scheduled based on the order lead time and when parts are ready to ship. The order will ship after the source inspection is complete. A customer-supplied dimensional print is required for this inspection.
Custom Inspection: Choose this option if your part requires custom inspection requirements such as, but not limited to, the following: Non-Destructive Testing, Serialization, Custom Sampling Plan, or if you would like to provide your own inspection datasheet. A customer-supplied dimensional print is required for this inspection.
Sampling Plan
Our Statistical Sampling Plan is based on ASQC Z1.4 2008 Level II with Zero rejects. Please refer to Table 1 below.
