The part needed to withstand under-dashboard temperatures up to 110°C continuous, survive 30G vibration testing, and meet PPAP Level 3 documentation requirements.</p> <p><strong>Challenge:</strong> Previous supplier had failed PPAP due to unacceptable warpage on the long flat face of the part — a 180mm unsupported span that distorted by up to 1.2mm after ejection.</p>
