Assembly parts are primarily used to connect and secure components, transmit loads and motion, and provide sealing or electrical paths—ensuring stable subsystem operation and overall vehicle safety.

● Function: Provide structural support and connections, transmit loads and motion, and deliver sealing or electrical grounding to ensure reliable subsystem performance.

● Operation: Multiple metal parts are joined into a single assembly using methods such as bolting, riveting, welding, press-fitting, or adhesive bonding. This ensures forces, motion, and electrical signals are accurately transferred between components while preserving alignment and sealing.

● Applicability: Widely used across automotive subsystems including engine and powertrain, chassis and suspension, braking and steering, fuel and cooling lines, body structure, doors/windows and interior trim, and electrical or sensor mounting brackets.
