RHI Powder offers expert burn off, sand blasting and pre-treatment services for powder coating professionals.
Burn Off ovens, also known as heat cleaning ovens, are used to remove organic materials such as varnish, paint, oil, and plastic from metal parts, allowing them to be reused. The combustible material is reduced to a fine light ash and fumes. The emissions from heat-cleaning ovens are quite low and the ash generated can usually go in the trash.
While there are several methods to removing excess powder coating from cleaning racks and hangers, and paint stripping, by far the most convenient and quickest method is to use a Burn Off or Hot Strip oven. Typically, these ovens use extremely high temperatures (up to 1000F degrees) to burn coatings to ash leaving the metal like new and ready to use.
This method is a safe and affordable alternative to time consuming and dangerous processes such as chemical and mechanical stripping. Chemical removal can be hazardous to both people and the environment, and sandblasting is abrasive and can damage the metal.
Burn Off ovens are typically reserved for large scale operations! RHI Powder brings cost-effective cleaning and de-coating services to virtually any size operation in Northern Nevada.

Benefits for a variety of Applications
Paint and Powder Coating
Hooks and racks or fixtures that carry product through the coating line accumulate overspray resulting in loss of conductivity. This loss of conductivity creates poor transfer efficiency resulting in uneven coverage and the potential for arcing which can cause a fire in the booth. The seriousness of these problems varies with the type of coating, the type and shape of the parts and the design of the fixtures.
Heat cleaning these components on a regular basis is the best solution.
Injection and extrusion molding equipment used in the production of plastic goods can become coated with plastic residue. Traditional cleaning methods such as chemical stripping, and torching create disposal, liability, and potential health problems. Torching creates localized smoke which can be harmful to the environment and to the employees doing the work. Heat cleaning eliminates the disposal difficulty and potential liability of chemicals as well as the problems associated with torching.
Electric Motor Rewinding and Copper reclamation
Electric Motor rewinders and Copper reclamation operators need to remove the insulation from copper windings and wires. Heat cleaning efficiently removes these coatings while softening the copper for rewinding and future use.
Sand Blasting, also known as abrasive blasting, is an essential process in the preparation of surfaces for powder coating. The first Sand Blasting process in the US was patented by Benjamin Chew Tilghman in 1870.
Sand Blasting is the process of forcibly propelling a stream of abrasive particles against a surface under high pressure. These particles travel at high velocity impacting the surface stripping it heavy scale, slag, and rust. The impact of the particles also leaves tiny craters in the surface. These tiny craters are lined by ridges which are pressed up on all sides and their depth are typically measured in thousandths of an inch. This result is called the “anchor pattern.”
At RHI Powder we have a 10 x 10 x 20 custom Sand Blasting booth for large projects along with a Blast Cabinet for detail work.
We use Aluminum Oxide as our primary medium. Aluminum Oxide is a low-iron content abrasive which will not leave any rust on the surface of your part. Rust deposits can often cause problems in subsequent future processes. Aluminum Oxide is a cost-effective blasting abrasive because it can be recycled and used for multiple passes in blasting process. Aluminum Oxide is a harder abrasive than most, resulting in less shatter of the particles which results in lower dust levels, while creating an optimal anchor pattern for Powder Coating.
Sand Blasting can be used to smooth or etch a surface, roughen a smooth surface and remove surface contaminants.
Our expert technicians ensure the integrity of your material, structures and surfaces while creating a clean, smooth, and durable finish. Whether it is a restoration project, adhesion purposes, or rust removal, RHI Powder has the capability get the job done cost-effectively and efficiently. Whether or not you plan to have your product powder coated we offer a blast only service.
Phosphate pretreatment cleans and etches metal surfaces creating an optimal surface for the powder coating to bond with, while leaving behind an insoluble coating of phosphate that helps prevent rust and corrosion.
Properly applied pretreatment coupled with quality powder enables metals to resist rust and corrosion much better than powder coating alone.
At RHI Powder, heated high-pressure spray phosphate pretreatment is primarily used on high quality steel to preserve the quality of the steel and the longevity of the powder coating for years to come. Our expert technicians apply phosphate pretreatment in a state of the art 20’ x 6’ bay.
Why phosphate pretreatment?
- Ensures superior bonding of powder coating
- Eliminates the appearance of oily patches on finished product
- Eliminates the appearance of “fish eyes” on finished product
- Increases resistance to adverse weather
