Properties of injection molded automotive parts

The testing of injection-molded automotive parts is a particularly important area in modern vehicle manufacturing, as these elements significantly affect the safety, durability, aesthetic appearance and user experience of vehicles. Our laboratory has more than twenty years of professional experience in the qualification, testing and initial sampling processes of automotive plastic parts. We perform our tests according to international and automotive OEM standards, so our partners receive full support for supplier compliance and quality assurance.

The purpose of the tests is to determine whether the injection-molded parts meet mechanical, thermal, optical, environmental and other functional requirements. The behavior of injection-molded plastics largely depends on the appropriate choice of raw materials, production parameters, tool design and technological stability, therefore detailed laboratory testing is essential for each part.

Properties of injection molded automotive parts

Our laboratory has a modern equipment park for performing geometric, mechanical, surface, optical, thermal and environmental resistance tests. With their help, the homogeneity, degree of crystallinity, impact resistance, surface quality, color stability, dimensional stability and deformation behavior of the material can be precisely determined. Our tests are reproducible, authentic and meet the strict requirements of the industry.

In the case of injection-molded automotive parts, we often test:

dimensional accuracy and dimensional stability,
surface defects, scratch resistance and coating properties,
material aging under various environmental influences,
changes in mechanical properties in the event of temperature changes,
functionality in the assambled state, under load.

Our laboratory regularly participates in first sampling processes (PPAP), where we provide manufacturers with authentic data on the conformity of the parts. Testing of injection molded parts is essential for quality control, production optimization, and development projects — especially in industries where tolerances are extremely tight and where consistent performance is essential.
