How are automotive interior injection plastic parts tested for quality and durability?

Automotive interior injection plastic parts are tested for quality and durability through a series of tests and inspections. Here are some common methods used for testing:
Dimensional Inspection: This is the most basic form of inspection where the parts are measured to ensure they meet the dimensional requirements as specified in the design.
Visual Inspection: The parts are visually inspected for any cosmetic defects such as scratches, sink marks, flash, and other imperfections.
Mechanical Testing: Parts are subjected to various mechanical tests such as tensile, compression, flexural, and impact tests to ensure they meet the required mechanical properties.
Environmental Testing: Parts are subjected to various environmental conditions such as high and low temperature, humidity, salt spray, and UV exposure to ensure they can withstand harsh conditions.
Fatigue Testing: Parts are tested for fatigue resistance to simulate long-term use and ensure they do not fail prematurely.
Chemical Resistance Testing: Parts are tested for their resistance to various chemicals, oils, and solvents that they may come into contact with in their application.
Noise, Vibration, and Harshness (NVH) Testing: Parts are tested for their contribution to noise, vibration, and harshness in the vehicle's interior.
Electrical Testing: Parts that have electrical components are tested for electrical functionality and compatibility with other electrical components in the vehicle.
These tests are performed in accordance with industry standards and specifications, and the results are used to ensure that the automotive interior injection plastic parts meet the required quality and durability standards.
