Everything You Need to Know About Mandrel Exhaust Bends: Why They’re Superior?
Posted by Profusion Exhausts on 15th Nov 2024
When it comes to creating a high-performance exhaust system, the choice of pipe bending technique is critical. Not all bends are created equal, and the difference between mandrel bends and crush bends can have a significant impact on the efficiency and durability of your system. At Profusion Exhausts, we pride ourselves on producing the best-quality mandrel bends in the UK. But what exactly are mandrel bends, and why are they better?
What Are Mandrel Bends?
Mandrel bending is an advanced method of shaping pipes and tubes that involves the use of a mandrel, a flexible steel rod or ball assembly inserted into the pipe during the bending process. This mandrel supports the interior of the pipe, ensuring it retains its round shape and consistent diameter throughout the bend.
Unlike other methods, mandrel bending produces a smooth, unrestrictive curve that is free from kinks, wrinkles, or deformation. The result is a high-quality pipe bend that maintains its structural integrity and airflow capacity.
How Are Crush Bends Made?
Crush bends, typically created on a huth machine or similar equipment, are a simpler and more cost-effective method of bending pipes. However, this process involves compressing the pipe as it bends, which can lead to several issues:
- Deformation: The pipe loses its round shape, creating flat or oval sections.
- Restricted Flow: The reduced diameter causes turbulence and back pressure, negatively impacting performance.
- Weakened Structure: Stress points are introduced, making the pipe more prone to cracking or failure over time.
While crush bends may be acceptable for low-cost or non-performance applications, they fall short for anyone looking to optimise their exhaust system.
Why Mandrel Bends Are Better
Performance Optimisation
Mandrel bends ensure a consistent and smooth airflow, which reduces back pressure and improves engine performance. This makes them ideal for high-performance vehicles or custom exhaust systems where every detail matters.
Strength and Durability
Because mandrel bending does not compromise the pipe's structure, the bends are more durable and resistant to wear. This is especially important for areas of the exhaust system that experience high temperatures and pressure.
Precision and Aesthetics
Mandrel bends produce clean, precise curves that look as good as they perform. Whether you’re building a custom exhaust system or a showpiece vehicle, these bends provide a professional, high-quality finish.
No Spring Back or Deformation
Unlike other methods, Profusion Exhausts’ mandrel bends retain their original round diameter even after cutting. This eliminates the need for additional reshaping or adjustments, saving you time and ensuring a perfect fit.
The Challenges of Mandrel Bending
It’s worth noting that mandrel bending is not easy. It requires advanced machinery, skilled operators, and meticulous attention to detail. The process is also more expensive compared to crush bending, but the results are well worth the investment. At Profusion Exhausts, we’ve mastered this complex technique to deliver bends that are second to none.
