What is HiPIMS Coating Technology and Why Choose It for Tools

In the world of advanced mechanics and industrial manufacturing, the quality and durability of tools play a crucial role. To ensure high performance and reduce maintenance costs, more and more companies are choosing coatings deposited using HiPIMS (High Power Impulse Magnetron Sputtering) technology—an advanced form of PVD coating.

But what exactly is HiPIMS technology, and why does it offer advantages over traditional systems?

What is HiPIMS Coating Technology

HiPIMS HiPIMS is a vapor-phase PVD coating process that uses extremely high-power, short-duration pulses. This technique generates a highly dense and ionized plasma capable of depositing thin films with an almost amorphous, homogeneous structure.

The result is a high-performance coating characterized by excellent adhesion, high density, and outstanding wear resistance—ensuring flawless and uniform coverage even on cutting edges.

Advantages of HiPIMS

HiPIMS coating technology stands out for its distinctive features, making it especially suitable for coating cutting and fine-blanking tools:

  • The plasma generated during the process is extremely energetic and highly ionizes the materials being deposited, creating a homogeneous coating structure free from preferential growth directions.
  • The high level of metal ionization ensures optimal adhesion to the substrate, allowing the coating to perform reliably even on the toughest materials.
  • Its compact and uniform structure makes the film hard, tough, and consistent, providing dependable cutting-edge coverage even under demanding conditions.
  • As a Sputtering-based process, HiPIMS allows the combination of a wide range of elements from the periodic table, including insulating materials—opening the door to coatings with innovative properties.
  • It is ideal for micro-tools: the absence of droplets and defects prevents the “antenna effect,” avoiding damage or rounding of cutting edges even in very small geometries.
  • It delivers excellent productivity, with deposition rates of up to 2 µm/h.
  • It significantly increases tool life compared to traditional PVD coatings, offering clear benefits in both performance and cost savings.

These advantages translate into longer tool life and reduced operational costs.

 

Applications of HiPIMS Coating Technology

HiPIMS coating technology is used across various industrial sectors, especially for cutting tools (milling, drilling, turning) where wear resistance is critical.

A perfect example is our Coral HiPIMS coating:

Coral is an AlTiSiN coating produced using HiPIMS technology, developed to maximize the performance of solid carbide cutting tools when machining medium- and high-hardness steels.

 

Maintenance and Cost Reduction

Thanks to HiPIMS coating technology, tools require less frequent maintenance and deliver longer, more reliable operating cycles.

Why Choose HiPIMS – In Summary

Choosing HiPIMS means investing in an innovative technology that ensures:

  • higher-performing tools,
  • reduced machine downtime,
  • lower overall costs,
  • greater market competitiveness.

For these reasons, HiPIMS has become the ideal solution for companies looking to maximize the productivity and reliability of their tools.
