The hidden strength of your plastic injection molded component could mean the difference between a groundbreaking innovation and a costly disaster.

Stress cracks in any plastic part indicate a serious problem that can be completely avoided with the right methods. There are two primary causes for these cracks, both related to how the molecules behave or interact.

Typically, we notice stress cracks appearing long after production, often months or even years later, primarily due to external influences like sunlight, extreme temperatures, or sometimes chemicals.

More intricate are the fine cracks that arise from the resin's orientation during the molding process. It's crucial to set the right temperature and pressure to ensure the strength of the part being produced.

If this is not done correctly, the resin can create counter-flows that go against the intended flow, causing the molecules to attempt to return to their original state to fill the gap. This results in compromised structural integrity, leading to reduced durability and lifespan compared to what could have been achieved.

In the automotive sector, numerous parts endure unpredictable stresses from end-users, along with the friction, heat, and impact from being used over hundreds of thousands of kilometers.

Selecting the right manufacturer, one who understands these challenges and can adjust the resin type and methods accordingly, is essential. One such supplier is ADIS Tachov s.r.o., a leading European auto parts provider.
