Inside JST Production
JST coordinates each project from drawing review and component machining through inspection, functional checks and controlled assembly.

Critical housings and drive components are machined against confirmed drawings and interface requirements.

Machining processes are selected for the component geometry and approved technical requirements.

Key dimensions are checked before components proceed to assembly.
Motor torque, speed, pressure, flow and leakage are checked alongside recorded winch load and operating data.

Components are organized and recorded for controlled assembly and project traceability.

Technical requirements are reviewed before a custom configuration is released to production.
