Contact us to discuss your issue and we will come up with a solution!

Our Approach to Advanced Metal Spray Shaft Repairs

After extensive use on the line, it’s normal for an industrial shaft to require reconditioning at some point during its lifetime. Whatever is riding on the shaft may cause damage or leave an indentation which can result in equipment failure. Metal spraying is a cost-effective and durable alternative. It involves coating alloys onto a damaged bearing surface to create a new, resistant shaft with high bond strength. This reconditioned surface finishing will be resistant to heat, corrosion, slipping, erosion, and more. HVOF coating will allow you to gain decades more out of your unit. If you have worn or damaged shafts on your line, call Houston Metal Spraying. Our one-stop-shop is your full-service repair solution.

Our Workflow

1
Speak with one of our engineers to discuss your shaft issue and receive a free quote and project timeline.

2

Schedule a pickup of the unit at your facilities (our logistics team can assist in the pickup and delivery).

3

We clean and inspect all shaft components to pinpoint any damage.
4
Apply the HVOF thermal spray coating, build it up oversize, grind it down, and recondition the shaft back to OEM spec.
5
Deliver your reconditioned, like-new shaft back to your location.

Start by setting up a call with one of our technicians to walk you through the process.

Common Shaft Issues:

If you hear abnormal clunking, vibrations or other strange sounds from your driveshaft, your equipment may be in need of remanufacturing or reconditioning. High-speed metal spraying is a great option if you have shafts with:
Corrosion
Metal flaking
Metal fatigue
Erosion
Metal cracking
Rust
Heat exposure
Distortion
And more!
Consider metal spray shaft repair to get your unit back on the line quickly and at an affordable cost.
Selected Materials
Our technicians can build up Nickel, Stainless Steel, Carbide, Stellite, Inconel, Carpenter 20, and Hastelloy, among other alloys. We can apply different materials for different applications depending on project requirements, so contact us today to discuss your needs.
Turnaround Time

We offer one of the quickest turnaround times in the business. Our team can recondition your unit and return it to your facilities in days, instead of weeks as with most of our competition. Our team will be at hand to make the whole process as smooth as possible.

Warranty
To ensure that you are completely satisfied with your reconditioned unit, we also offer a 12-month warranty that begins on the date of installment. This means that until the shaft is installed and in use, your warranty will not start. When looking for the best metal spray shaft repair provider, you will not find a better cost, warranty, and project turnaround time. Contact us to find out more about our competitive rates, high quality service, and extensive warranties.
