    Use the Damage Pattern to Identify Its Timing<\/h2>\n

    Release damage should be separated from molding distortion. The same bent feature can result from uneven cooling, core retention, ejector force, robot contact, or packaging compression. Evidence from timing helps narrow the cause.<\/p>\n
