    Can you reduce  your cost of quality by repairing your offset-web press cylinders?

 

 

 Engineered Services for Print Cylinders include: 

  • Complete Plate & Blanket Cylinder reconditioning
  • Journal repairs
  • Bearer changes
  • Dynamic balancing

 

 Journal Repairs  

Maybe you don’t need to repair the whole cylinder? 

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

Sometimes plate or blanket 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 press running effectively.

The cost of repairing a journal, versus replacing or reconditioning an entire 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!

What is thermal spraying?

??
Basically, thermal spraying is when a coating material (in powder, rod or wire form) is heated to a certain 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!

Consider HFW Industries ‘One Source’ service in helping extend the life and reducing the cost of your application!

Can Hardfacing Reduce Your Costs Due to Corrosion, Wear and Down-time? http://www.hfwindustries.com/blog/2011/05/what-is-hardfacing-can-hardfacing-reduce-your-costs-due-to-corrosion-wear-and-down-time/ http://www.hfwindustries.com/blog/2011/05/what-is-hardfacing-can-hardfacing-reduce-your-costs-due-to-corrosion-wear-and-down-time/#comments Tue, 10 May 2011 19:11:13 +0000 admin http://www.hfwindustries.com/?p=636 The total cost of wear and corrosion on industrial equipment each year is so high it’s incalculable. There’s a lot of opportunity to increase your process up-time by improving your wear and corrosion resistance by using hardfacing!
  
Mechanical properties of many substrates don’t include inherent corrosion resistance and thus require hardfacing to enhance their performance.
  
Ask us how we help our customers with hardfacing technology when we combine it with our machining, finishing and assembly capabilities!
 
So What Is Hardfacing? Hardfacing, or hardsurfacing, is a term used when a layer of weld overlay is applied over a base material in order to prolong the life or restore dimensions of the component. The bond formed between the overlay and base metal is metallurgical.

Methods for applying hardfacing include (but are not limited to):

  • Plasma Transferred Arc
  • Oxy-Acetylene Torch
  • TIG/ MIG/ Sub Arc

 Typical base materials that are hardfaced include:

  • Low & Medium Carbon Steels (ex: 1020/ 1030)
  • Alloy Steels (ex: 4140, 8620)
  • Stainless Steels (ex: 304/ 316)
  • Super Alloys
When to Consider Hardfacing?
  
~ When a component needs to be replaced and repair may be a low-cost option
  
~ When your application is in a highly corrosive atmosphere
  
~ When wear on a component becomes an issue over it’s life cycle
  
Think about your equipment’s life cycle, up-time requirements, part inventory cost and cost to replace versus repair a process component…
  
Common Hardfacing Applications
 
Steam valve components Compressor rods and sleeves
Pump cases and components
Mixing equipment
Extruder screws
Process rolls
Centrifuge screws
Seals
Fan blades
Molds
Dies
Plungers
Mining equipment
… and many more!

Every application is different. Reasons vary as to what will be the best method for hardfacing and what materials should be used. Typical materials are noted below.

 Commonly applied materials for reducing wear: 

(Includes wear via combinations of abrasion, impact, metal-to-metal, heat, etc.)

  • Tungsten carbide
  • T420 Stainless Steel
  • Cobalt based materials
  • Nickel based materials
Commonly applied materials for reducing corrosion:
 
 

 

  • T316 Stainless Steel
  • Hastelloy ‘C’ 276
  • Cobalt based materials
  • Nickel based materials

Our extensive in-house manufacturing and repair capabilities with almost 65 years experience give us the ability to offer you high-quality and timely services without the hassles of multiple vendors and blurred lines of responsibility.

The two surfaces form a mechanical bond and the substrate temperature generally remains below 300 degrees fahrenheit so zero distortion occurs.

The thermal spray process is used for the purpose of restoring component size to OEM dimensions, and extending service life through enhancing resistance to abrasion, wear, heat and corrosion, among others. The results are lower maintenance costs and increased uptime for our customers!

Additional benefits to thermal spraying include:

  • Components can be re-engineered using higher performance materials
