Mass production

No goods skip quality checks. Every finished connector will be tested one‑by‑one at our inspection station. Only qualified items get well packed and then arranged for shipment. With more than 13‑year connector‑making experience, we keep close control over each stage from mould opening, CNC machining to final inspection, to make sure every batch meets MIL‑DTL‑38999 requirements.
How to purchase

Every unit will go through necessary quality checks before packing, and we will arrange worldwide delivery when all work is done. This one‑stop workflow works well both for standard D38999/20FD18PB and slightly modified versions for your projects.
