Friction Drilling in HVAC industry

Revolutionize your production process, replace Rivet, Weld or Press nuts.

As an innovative designer, you aim to build high-performance systems that are leak-free, efficient, and sustainable.

Thin copper and stainless-steel materials bring unique challenges especially at T-joints and raised edges.

Traditional methods like welding and soldering often lead to misalignments, weak joints, and costly leaks.

What if there was a solution for missed inserts, slipping, preventing expensive rework and say goodbye to design limitations?

The most important questions for an engineer, answered quickly.

A Flowdrill friction-drilled connection is known for its high strength, depending on the material, wall thickness, thread size, and application. In many cases, it can be stronger than alternatives such as rivet nuts, blind rivet nuts, or press-in nuts. For example, a friction-drilled connection in 2.0 mm thick steel can withstand a force of up to 2.7 tons, approximately 26.5 kN. This makes it a strong and reliable alternative to conventional mechanical fastening methods.

Yes, Flowdrill can be excellently integrated into automated production processes, including robotic welding environments. We actively support customers with this and maintain strong relationships with experienced machine builders, including those in the automotive industry.

Copper and brass (CuZn39Pb3, CW614N): Is suitable for friction drilling, but requires adjusted parameters. Please contact us, we are happy to help you!

Your Challenge: Say goodbye to leaks and production inefficiencies

Traditional joining methods like welding and soldering often lead to:

  • Misaligned joints, risking system failure.
  • Leaks due to poor welds, reducing efficiency.
  • Costly rework, which delays production and impacts profitability.
  • Chips and burrs in the final product

The solution: Friction Drilling with Flowdrill

Using only the base material, Flowdrill offers an alternative that:

  • Creates durable, leak-proof connections
  • Reduces production costs
  • Is a chipless process
  • Simplifies manufacturing
  • Supports more sustainable production

All without additional fasteners or welding.

Why choose Friction Drilling for HVAC systems?

Benefits for HVAC designers:

Precision and durability:
Strong, accurate connections using only the base material, ideal for thin copper and stainless steel.
