Automotive OEM Spring Projects

Representative automotive spring manufacturing projects across key vehicle systems, demonstrating real OEM-level engineering challenges and production outcomes.

All projects shown reflect production-level validation rather than prototype-only evaluation.

Automotive manufacturing system environment

Project Overview

This page presents a curated selection of automotive OEM spring projects. Each project represents a complete system-level application rather than an individual spring type. The cases reflect real engineering decisions made under production, durability, and NVH constraints. All projects shown are linked to detailed case pages.

Common Engineering Challenges in Automotive Spring Programs

These challenges represent recurring acceptance drivers observed across OEM automotive programs, rather than isolated design considerations.

High-cycle fatigue under mixed occupant and road-induced loading — evaluated through durability cycling and performance drift observation

NVH sensitivity caused by micro-motion and interface friction — screened under vibration exposure and post-assembly conditions

Torque repeatability in adjustment and locking mechanisms — assessed across thermal cycles and full operational range

Performance drift and lot-to-lot variation in mass production — tracked through incoming inspection and process capability monitoring

Durability validation under temperature and vibration coupling — verified through combined environmental and mechanical stress testing
