About APG
Your Local Manufacturing Partner
APG was founded on the belief that Arizona OEMs deserve a trusted local partner — someone who knows the manufacturers, understands the technology, and shows up when it matters.
Our story
Built on relationships. Driven by results.
Assembly Partners Group LLC was established to fill a real gap in the Arizona manufacturing market: OEMs needed a single, accountable partner who could coordinate across multiple specialized manufacturers without the overhead of managing each relationship independently.
We built our network carefully — selecting partners like Summit Interconnect, Dutek, DDH Enterprise, and 3G Shielding Specialties not just for their capabilities, but for their commitment to quality, responsiveness, and long-term partnership.
Today, APG serves customers across aerospace, defense, medical, semiconductor, and industrial markets — providing the coordination, engineering support, and local presence that makes complex manufacturing programs run smoothly.
