In today’s industrial world, every second lost becomes a cost. That’s why more and more companies are investing in solutions that increase productivity without compromising on quality. One technology that truly makes a difference? High Frequency (HF) Welding.

Why choose high frequency welding?

HF technology is especially valued in industries such as automotive, packaging and conveyor belts, because it allows for:

  • Extremely fast welding cycles, even with complex materials
  • Strong, durable bonding, with no weak spots
  • Consistency and repeatability, ideal for serial production
  • Low energy consumption, with high performance

Customization machine is the key

One of the most common problems in production lines is the use of standard machinery that doesn’t align with a company’s specific needs.

At REG Galbiati, each machine is custom-designed based on:

  • Material type (PVC, PU, technical fabrics)
  • Type of finished product
  • Production targets
  • Plant layout and available space
  • Desired level of automation

Consistent quality means fewer downtimes

REG Galbiati’s high frequency welders are engineered for long-lasting performance and reliability.

  • Longer machine lifespan
  • Fewer breakdowns
  • Constant quality from day one

This means higher uptime, lower costs, and less stress for your production team.

Take your efficiency to the next level

If you’re evaluating how to optimize your production line or replace an aging welding system, working with a specialized partner can make all the difference.

With over 70 years of experience, REG Galbiati designs and manufactures tailor-made HF welding machines that help industrial clients around the world achieve:

  • Higher productivity
  • Maximum reliability
  • Certified quality standards

High-Frequency Welding vs. Other Welding Techniques

In industrial manufacturing, choosing the right welding method can significantly impact efficiency, product quality, and costs. One of the most advanced and widely adopted technologies is High-Frequency (HF) Welding, especially in the production of conveyor belts and synthetic material processing. In this article, we’ll compare high frequency welding with more traditional welding methods.

What is high-frequency welding?

High-frequency (HF) welding uses electromagnetic waves to generate internal heat within thermoplastic materials, fusing them from the inside out. This technique is particularly effective for materials like PVC, TPU, PET, and other films with dielectric properties.

Advantages of high-frequency welding

  1. High Precision and Uniformity. HF welding ensures seamless, consistent bonds—even on thin or intricate surfaces—offering excellent aesthetics and superior mechanical resistance.
  2. Strong and Durable Seals. Thanks to internal material fusion, HF welding creates a molecular-level bond, ideal for products subject to mechanical stress and long-term use.
  3. Fast Production Cycles. HF welding has significantly faster cycle times compared to other techniques, boosting productivity and reducing overall lead times.
  4. No Direct Contact with Heat Sources. With no direct heat elements, material degradation is minimized, eliminating burns, scorching, or deformation.
  5. Easy Automation. HF welding integrates smoothly into automated systems like those developed by REG Galbiati S.r.l., maximizing efficiency and quality control.

Comparing HF Welding to Other Techniques

When we compare high-frequency welding with hot welding, we immediately notice that the latter, although more affordable and widespread, does not guarantee the same level of joint quality. Processing times are longer, and process control is less precise, which can result in lower aesthetic and functional performance.

Ultrasonic welding, on the other hand, is suitable for certain types of rigid plastics and offers good speed. However, it requires highly specialized equipment and tends to be less versatile than HF technology.

Another alternative is impulse welding. In this case as well, the joint quality and ease of automation are not comparable to those achievable with high-frequency welding.

HF welding stands out as the most high-performing solution for those seeking speed, consistency, and seamless integration into automated industrial processes.
