Manufacturing Capabilities
CNC Precision Machining
Our CNC turning centers and machining centers produce connector shells, shells, collets, and retaining rings to tolerances of +/-0.01 mm. Primary materials include 316L stainless steel, titanium alloy (Grade 5), PEEK polymer, and Delrin (acetal). All dimensions are 100% inspected on CMM (coordinate measuring machine) before assembly.
Contact Pin Manufacturing
Electrical contacts are machined from beryllium copper (BeCu) rod to achieve the spring-force and conductivity required for reliable underwater mating. Contacts are electroplated with hard gold (0.5-1.0 micron gold over nickel) using in-house plating lines. Gold plating ensures corrosion immunity in saline environments and maintains contact resistance below 5 milliohms over 500+ mating cycles.
O-Ring and Seal Assembly
O-ring installation is performed in a controlled environment to prevent contamination. We use primary O-ring seals of NBR (Nitrile Butadiene Rubber) as standard, with EPDM, Viton(R), and Silicone options for specialized media compatibility. Secondary backup seals are integrated for connectors rated beyond 3,000 m.
Cable Termination and Overmolding
Cable-to-connector termination is performed using precision crimp tooling and soldering where required by contact type. Overmolding uses polyurethane (PU) compound applied by injection molding for a hermetic, mechanically robust cable entry that resists bending fatigue and pull-out forces exceeding 500 N.
Fiber Optic Assembly
Our hybrid opto-electric connectors incorporate single-mode and multimode optical fibers. Fiber end-face preparation uses angle polishing machines, and insertion loss is tested on every unit using OTDR and optical power meter. Target insertion loss: <0.5 dB.
Testing Equipment and Protocols
| Test Equipment | Test Performed | Acceptance Criterion |
|---|---|---|
| Hydrostatic Pressure Chambers | Full-assembly pressure soak at 1.5x rated depth | Zero leakage after 30 minutes |
| Hi-Pot Tester (5 kV) | Dielectric withstand between contacts and shell | No breakdown at 1,000 VDC test voltage |
| Milliohm Bridge | Contact resistance, 4-wire measurement | <5 mO per contact pin |
| Megohm Tester (500 VDC) | Insulation resistance between contacts | >100 MO |
| Salt Spray Chamber | Corrosion resistance per IEC 60068-2-11 | No red rust after 96-hour exposure |
| CMM (Zeiss / Mitutoyo) | Dimensional verification of machined components | +/-0.01 mm tolerance |
| OTDR / Optical Power Meter | Fiber optic insertion loss (hybrid connectors) | <0.5 dB insertion loss |
| Thermal Cycling Oven | Temperature cycling -40 deg C to +100 deg C | No seal failure after 10 cycles |
