Thermal Spray Applications
Thermal spray coatings are used throughout many industries, from chemical, to power generation, to
steel production to semiconductor.
New applications are constantly developed.
Below lists general areas where thermal spray may be of
significant benefit…
~ Replacement of chrome plating using tungsten carbide thermal spray
~ Life cycle improvements where wear and corrosion lessen the life of your equipment

~ Restoration/ repair of old/ worn components or equipment.

Some common items repaired include…
  • Process Rolls
  • Shafts
  • Valve Components
  • Bearing Housings
  • Gear Boxes
  • Pump Components
  • Agitators
  • Printing Cylinders & Rolls
  • And many more…

What is thermal spraying?
Basically, thermal spraying is when a coating material (in powder, rod or wire form) is heated to a designated temperature and then propelled in a molten state onto a substrate. The result is a mechanically bonded coating that will restore size or protect the substrate in the application.
It’s amazing that the thermal spray process, initially developed over 100 years ago in Switzerland by Max Ulrich Schoop, today uses technology that can spray coatings at supersonic speeds!
What separates HFW from our competition is our 60 years of expertise in thermal spray coating with complementary machining, finishing and assembly capabilities! 
This unique ‘One Source’ capability offers you high quality, timely manufacturing and repair service without the hassle of multiple vendors and blurred lines of responsibility.

How are thermal spray coatings applied?

HFW remains at the forefront of thermal spray technology by using state-of-the-art equipment, including robotics, with our 25 plus thermal spray systems.

The process chosen is based on what is best for each application. That may depend on the material to be sprayed, the substrate and the result desired. HFW has in-house laboratory facilities to qualify and test coatings to customer required specifications.

Thermal spray  processes we perform in-house include:

– High Velocity Oxy-Fuel or HVOF Coatings (pictured above)- dense metal/ carbide coatings

– Plasma Coatings- metal, ceramic and cermet coatings

– Sprayweld Coatings- metal alloys fused to the substrate

– Rokide Coatings- select ceramic coatings

– Metallize Coatings- metal coatings by wire or powder processes

 

HFW can apply any material that does not decompose as it is melted. These materials include pure metals, ceramics, cermets and polymers.

With over 60 years of proven success in extending equipment life, HFW will work with you to develop coatings specific to your application . We have been successful in designing coatings that have extended the life of equipment over ten-fold, savings millions of dollars for our customers! Ask us how our coating technology may be able help in your application!

Could repair or re-stubbing of journals be all you need to fix your roll or cylinder?

May 24th, 2011

Over time, journal diameters can wear and cause a reduction in production quality and efficiency.

Sometimes production rolls or print cylinders require complete reconditioning, but sometimes a simple repair to the journal, or a re-stubbing of journals may be all it takes to keep your production line running effectively.

The cost of repairing a journal, versus replacing or reconditioning an entire roll or cylinder equals reduced maintenance costs.

Replacing and repairing journals has been an important part of how we save money for our customers every day.

Let HFW help you find ways to minimize your repair costs, while maximizing production!
