HMC is certified under the latest standards for both AS 9100 D and ISO 9001:2015. As part of the AS 9100 certification process, our QMS has been audited and found to conform with the quality standards that are now in effect for the aviation, space, and defense industries.

At HMC we know that successful quality control is only possible when the quality and manufacturing processes are integrated, and for this reason no job is released to production without an approved Quality Plan.

As a a holder of a BATF Class 7 license, HMC can perform virtually any machine work necessary on a firearm during the process of preparing the firearm for subsequent sale. For example, we can help with machining or other work on firearms, or firearms frames or receivers, to  prepare them for subsequent sale by the primary manufacturer. Please contact us with  your firearm sub-manufacturer needs.



Quality Assurance has a role in every stage of operation at HMC, our quality staff works closely with procurement and production staff to make certain that customer material specifications are adhered to by using only certified materials while ensuring material traceability is maintained as required by you, the costumer.

HMC follows a very stringent quality and inspection procedure and is committed to quality in every step of the production processes, including first article inspection, first piece inspection (if required), followed by strict in process quality control guidelines, including in-process inspections during the production of your parts.

We conduct internal audits performed by in house quality auditors. Our QMS is designed to catch and fix problems before they reach you, the customer.

All metrology instruments such as surface plates, comparators and digital height gauges are calibrated and traceable and are tracked on a special registry, as per AS 9100 D requirements. HMC is always willing to add inspection tools to meet the requirements of our customers.

Mitutoyo High Precision Digital Height Gage

HMC uses a 24-inch Mitutoyo High Precision Digital Height Gage for tight tolerance measurement. This tool is capable of .00005” Resolution.  Go/No GO judgment is performed by setting the upper and lower tolerances. If a result is out of tolerance, the display backlighting changes from green to red, so tolerance judgments can be made at a glance.
