Cold gas coating
Patented cold gas spraying, e.g. for induction bases


For the highest demands - made in Thuringia
Our innovative cold spraying process enables the precise application of coatings on rotationally symmetrical parts with a diameter of up to 400 mm. This state-of-the-art thermal spraying technology is primarily used in the production of induction coatings for aluminum and copper cookware.
Awarded as “Hidden Champion”
Patented technology for maximum induction performance
With the patented CSI process, BAF Industrie- und Oberflächentechnik GmbH is setting new standards in the finishing of induction pans. The Gigant Newline highlight series is the result of this innovative technology and impresses with its outstanding properties.
The advantages of our cold gas spraying:
- Up to 30 % faster heating of the cookware
- No flaking of the coating as with conventional thermal processes
- No risk of corrosion on the underside of the cookware
- The base remains uncoated and is turned to a shine
How does the cold gas process work?
In cold gas spraying, we use nitrogen as the process gas, which is fed through a spray gun under high pressure (up to 36 bar) and at temperatures of up to 720°C. The gas reaches supersonic speeds and cools down considerably at the same time. The gas reaches supersonic speeds and cools down considerably at the same time. The coating powder is introduced into the gas flow and accelerated to speeds of up to 1200 m/s. On impact with the component, a solid, dense coating with optimum adhesion is created.

Possible applications

Our patented cold gas spray technology enables optimum heat transfer and durability for induction bases for aluminum and copper cookware.
Induction floors
The perfect choice for your aluminum and copper cookware. Thanks to our innovative cold gas spray technology, we guarantee optimum heat transfer from the hotplate to your cookware.
Rotationally symmetrical parts
Processing with our machine is possible up to a diameter of 400 mm, larger diameters require an individual solution.
Versatile applications
Also suitable for other coating requirements, e.g. application of various precious metals such as gold or silver.

FAQ
Cold gas spraying for the highest demands
What is cold spraying?
In cold gas spraying, a coating powder is applied to a workpiece using a high-energy gas stream. This process makes it possible to create very thin and even layers with excellent properties.
How does the cold spraying process work for you?
We use nitrogen as the process gas, which is fed through a high-performance nozzle at high speed and temperature. The coating powder is introduced into this gas flow and accelerated onto the workpiece. A solid, dense layer is created on impact.
For which workpieces is the process suitable?
Our process is specially designed for rotationally symmetrical parts, i.e. parts that have a circular basic shape. The maximum diameter we can process is 400 mm.
What are the advantages of cold gas spraying for induction bases?
- Faster heating: Optimal heat transfer means the cookware heats up to 30% faster.
- Durable coating: The coating is very robust and resistant to chipping.
- Corrosion protection: The underside of the cookware is not coated and therefore remains corrosion-free.
- Aesthetics: The base is turned to a glossy finish for a high-quality appearance.
Which materials can be coated?
Our process is particularly suitable for aluminum and copper. However, other materials and alloys can also be coated.
Can I also request coatings other than for induction bases?
Yes, our process is very flexible and can also be used for other applications. For example, we can also apply precious metals such as gold or silver.
What tolerances can you achieve with cold gas coating?
We can produce very precise and uniform layers with low tolerances.
Is the process environmentally friendly?
Yes, our process is environmentally friendly as we only use small quantities of coating powder and no harmful waste is produced.
How long does the coating process take?
The duration of the coating process depends on the size and complexity of the workpiece. We will be happy to provide you with an individual offer.
