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! |

High quality print is imperative in today’s environment. The cost of scrap and press downtime due to poor quality can cost you money or even a customer!
For over 40 years, HFW Industries has worked with offset-web press OEMs, rebuilders and print facilities to keep production running profitably by repairing press cylinders. Better running cylinders equals better running presses.
It all starts with a detailed inspection of your worn cylinders to determine the work scope involved. See below for details…
|
 Going from worn to new
Every print cylinder that comes into HFW for reconditioning goes through the exact process outlined below, resulting in the same outcome – highly satisfied customers!
Step 1: Detailed Inspection
- Disassembly and cleaning
- Preliminary inspection of cylinder
- Received condition (Diameter, TIR and surface condition)
- Review parts for condition
Step 2: Engineered Services Manager Review
- Analyze condition and establish work scope
- Review with customer (If desired)
- Prepare quotation (Or work scope summary)
- Submit to customer
Step 3: Customer Approval
- We will not initiate work until our customer fully approves and understands the work scope entailed
Step 4: Remanufacture
- Prepare for coating
- Establish Duragap® protective edge (If desired)
- Thermal spray (Via metallize, plasma spray, or HVOF processes)
- Proof finish
- Precision machine slot (gap) to required width and radii
- Dynamic balance and make necessary weight corrections (If required)
- Assemble and install new bearers, bearings, and component parts
- Finish grind to specifications
- Final assembly
- Inspection / documentation
- Packaging

What are thermal spray coatings?
Can they help you increase equipment service life and save cost by salvaging worn parts?
|
|
|
Common Thermal Spray ApplicationsThermal 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??
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 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!
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.
