Could repair or re-stubbing of journals be all you need to fix your roll or cylinder?
May 24th, 2011Over 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!
What is Hardfacing? Can Hardfacing Reduce Your Costs Due to Corrosion, Wear and Down-time?
May 10th, 2011Methods 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
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
- 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.

HVOF Coating Services – High Velocity Oxygen Fuel Spraying
February 16th, 2011At HFW, we specialize in HVOF coating services. The benefits to HVOF coating include:
- Components can be re-engineered using higher performance materials
- Wear is prevented or retarded
- Improved functionality and life of process-related or OEM equipment
- Improved lead time—repairing components vs. manufacturing
- Obsolete parts no longer available from the OEM are able to be repaired/salvaged
Contact HFW today to learn more about our HVOF coating process and other thermal spray applications.
Printing Press Cylinder Remanufacturing Process
February 10th, 2011Every 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
Benefits of Thermal Spray Services
February 8th, 2011Thermal spraying includes a variety of processes where molten material is propelled onto a substrate. 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
- Wear is prevented or retarded
- Improved functionality and life of process-related or OEM equipment
- Improved lead time—repairing components vs. manufacturing
- Obsolete parts no longer available from the OEM are able to be repaired/salvaged
