Mass production

D38999/20WC98SC is a wall mount circular connectors receptacle built to MIL-DTL-38999 standards. Every single unit goes through our full in-house production workflow, from mold making all the way to final delivery.
We start by manufacturing moulds for insulators and sealing bodies. These plastic and silicone parts are key components for D38999/20WC98SC. Meanwhile our CNC workshop machines socket shells and plug shells with tight dimensional control. All raw components are separately prepared before assembly.
Once insulators, sealing bodies and alloy housings are ready, workers assemble each connector carefully. After assembly finishes, every D38999/20WC98SC will enter our inspection station. Our QA team checks appearance, plating, dimension and electrical performance one by one. Only parts passing all tests move on to packing.
Products get wrapped and packed properly to avoid scratches or impact damage during transit. We work with DHL, UPS, FedEx and EMS for global shipments. Tracking information will be sent once parcels leave our factory.
This receptacle features a scoop-proof alloy shell and integrated silicone sealing. It can resist shock and vibration reliably, well suited for rugged field equipment. Mixed power and signal contact layout is supported, and standard panel mounting can be done without extra machining. Matching M39029 contacts and extraction tools are available upon request.
We hold stocks of core components, so sample orders can be arranged quickly. For bulk demands, our production line handles mass manufacturing while keeping consistent quality. If you have custom requirements for your project, our engineering team can also support drawing adjustment.
