Success Story: Automotive Bracket Replacement
The Challenge
A European automotive OEM faced recurring issues with a front-end engine bracket made from die-cast aluminum. The heavy metal part contributed to excessive vehicle weight, impacting fuel efficiency. More critically, the bracket experienced premature cracks in high-vibration zones due to metal fatigue, leading to warranty claims. The client needed a solution that was lighter, more durable, and cost-effective at a system level.
The Solution:
The component was redesigned for injection molding using LFT-G® PA66 GF30. This high-performance engineering plastic was selected for its superior fatigue strength, high stiffness-to-weight ratio, and excellent dimensional stability under high-temperature, high-stress conditions.
The Result
The switch to LFT-G® PA66 LGF30 was a decisive success:
- Weight Reduction: Achieved a 55% mass saving vs. aluminum, contributing directly to improved fuel efficiency.
- Enhanced Reliability: Eliminated fatigue failures, passing all durability tests, and removing related warranty claims.
- System Cost Efficiency: Lowered the total installed cost through part consolidation and simplified assembly.
FAQ
Q: What is LFT-G® PA66 GF30 material?
A: LFT-G® PA66 GF30 is a 30% Long Glass Fiber reinforced PA66. It provides superior impact strength, fatigue resistance, and dimensional stability compared to short-fiber grades, making it ideal for demanding structural components.
Q: What is the difference between PA66 GF30 and PA66 LGF30?
A: The key difference is the fiber length. PA66 LGF30 (Long Fiber) offers dramatically higher impact resistance, lower anisotropy, and better long-term creep performance than PA66 GF30 (Short Fiber), solving brittleness in critical applications.
Q: Why choose LFT-G® PA66 GF30 to replace metal?
A: Choosing LFT-G® PA66 GF30 over metal delivers ~50% weight reduction, corrosion resistance without coating, and part consolidation to reduce assembly. It is the optimal material for lightweight, durable structural designs.
