HFW is a pioneer in using thermal spray coatings for wear and corrosion prevention. Our 75+ years of expertise have saved customers millions of dollars through extending equipment life and reducing downtime.
Background:
Since 1947, HFW has remained at the forefront of industry innovation with continual investment in thermal spray technologies and systems. Whether it was our being the first commercial licensee of the Norton Rokide™ process in 1957, or developing new coatings and investing in new thermal spray technologies in our robotic production cells, we do so to ensure our customers receive the best possible quality, delivered on-time.
Thermal 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!
Benefits:
Some important 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
- Enhance the lifespan of new equipment
Additionally, we partner with customers and suppliers to develop and apply proprietary thermal spray coatings that are application specific.
