Trusted where failure
is not an option.
A majority of what we machine flies. The rest goes into defense platforms and industrial equipment — and every part, whatever it ends up in, gets the same process control, the same inspection and the same scrutiny.
Industries we serve
Aerospace
Flight-critical fuel-system, hydraulic and engine hardware for tier-one OEM divisions — fuel nozzles and swirlers, gear-pump housings and impellers, valve bodies, poppets and spools, bearings and matched plate sets — from first article through decades of production under certified-supplier delegation.
Defense
Build-to-print defense articles for land, sea and air platforms, machined under a documented ITAR compliance program — DDTC registration, a 100% U.S.-person workforce, access-controlled technical data, restricted-party screening and CMMC Level 2 readiness in progress — with full flow-down of your DFARS and quality clauses.
Nuclear
Precision components for nuclear power and naval applications — an explicit part of our AS9100D certified scope — machined from customer-furnished or certified material with the lot control, heat-number traceability and inspection records nuclear quality programs require.
Industrial
High-value industrial hardware — metal-cutting tooling, hardened wear components, pump and valve parts for energy and process equipment — for customers who want aerospace-grade process control and documentation without paying for a second supplier to get it.

Trusted with your inspection.
Our customers have awarded Sunset certified-supplier status — accepting our final inspection in place of their own source inspection. That delegation is audited by them, re-earned on every lot, and is the reason a part from Sunset goes straight to stock.
