JK Corporation leads end-to-end Design-to-Delivery OEM/ODM programs—from planning and tooling oversight to QC, lead-time control, export, and delivery.

Our locks are validated to Japan-spec and quickly localized to each country’s standards (mounting, certification, IP/EMC, labeling/packaging).

We supply key components (mortises, DC5V geared motors) and electrical parts (step/synchronous motors, oil dampers, diaphragm water & air pumps), custom-engineered across voltage, torque, gear ratio, shaft, connectors, noise/life grade, and materials/coating.
