An audio interface panel is the handshake between your electronics and the cables the world plugs in. Every XLR hole, every switch label, every chamfer is where users judge build quality — our panel program gets those details production-consistent.
What we manufacture: XLR/TRS connector panels; control-surface faceplates; I/O rear panels for consoles and interfaces; rack-ear and side-cheek panels; mixer sub-panels — 6063 aluminum, machined and stamped, from 1.0–4.0mm.
Alignment is the product: connector cutouts are positioned from your PCB or mechanical CAD data to ±0.02mm, so Neutrik-style connectors seat square without filing; silkscreen legends land centered in their windows because print tooling is registered from the same datum as the machining.
Feel-good surfaces: polish then fine-sandblast before anodize — the finish that reads premium in a dim studio and doesn't show fingerprints on tour. Anodize colors from classic black to champagne with ΔE batch control; laser-filled legends for multi-color branding.
Volume ready: 500-piece boutique console runs to 300k+ annual panel programs, with archived CAM so revision 4 matches revision 1 when your product line turns over.
Machining and printing registered to one datum — connectors seat square, legends land centered.
Polish + fine sandblast under anodize: premium in dim light, fingerprint-resistant on tour.
CAM archived per program; rev-4 panels match rev-1 when your line turns over.
From aerospace-grade aluminum to medical-certified engineering plastics, our in-house CNC machining centers work a broad range of metals and plastics under one roof.
