The invention of the powder coating process and the powder coating oven emerged as a response to the many issues that existed in the liquid finishing industry. The main issues were that the finishes did not last long enough, products contained and released volatile organic compounds when resins were being applied and the high costs associated with maintaining the proper safety equipment and pollution control units that were required for applying traditional liquid finishes.
In the 1940’s, the European finishing and coating industries were under tremendous pressure to find a more environmentally friendly way to process and dry coatings. The current method of coating was flame spraying, which utilizes combustible gasses to create the energy necessary to melt the coating material.
It was in the late 1940’s that Dr. Erwin Gemmer developed a way to fluidize the bed application for thermoplastic resins on metal as a more efficient alternative to flame spraying.
The new powder coating method could be applied to new or used parts after they have been degreased and chemically cleaned to provide a proper surface. The coated part is then placed in a powder coating ovenfor 2-4 hours to complete the process.
Over the next 40 years, major improvements in coating and application processes and the efficiency of the powder coating oven brought the industry huge amounts of growth. By the 1980’s, the process and the powder coating oven had gained enormous popularity as breakthrough advances in resinsand powder coating oven procedures had decreased waste, increased efficiency and lowered processing costs.
Today this coating can be applied and dried in a powder coating oven in as little as an hour. A standard powder coating oven on the market today can dry a coating resin in 15 minutes. These technological improvements continue to be driven by the automotive, aerospace, appliance and general industrial markets.

The American Iron and Steel Institute (AISI) recently released their 2014 Annual Statistical Report (ASR). The report discusses good news and continued growth in the iron and steel industries as well as the heat treat furnace industry.
The American Iron and Steel Institute report details how the industry has seen an increase in U.S. steel production, shipments and imports in 2013. That steady growth has also continued into 2014. These increases in production and imports have also led to increased sales of heat treat furnace units as many manufacturing companies continue to bring processing back in house. Increases in Chinese wages as well as fuel charges have steadily brought more industrial manufacturing and metal working jobs back to the U.S.
The industrial furnace industry has enjoyed continued growth in the sales of heat treat furnace units with both total and finished steel imports quantities levels reaching to near record levels. These imports amass to a record 28% share of apparent steel supply.
Report details also show a steady industry growth over the last few years that is showing no signs of slowing. U.S. steel shipments were counted at 98 million net tons which is a 3% increase from the previous year and a 6% increase from the most recent five-year average solidifying the market growth. This industry growth has helped to fuel the growing number of U.S. manufactures who require a heat treat furnace for production. U. S. raw steel production was 97 million net tons in 2014, a 1% increase over 2013.
In other manufacturing news, President Obama recently signed two significant trade initiatives: Trade Promotion Authority (TPA) and the extension of the Africa Growth and Opportunity Act which includes renewal of Trade Adjustment Assistance (TAA) and trade remedy improvements. The steel and heat treat furnace industries have applauded the action, particularly enactment of the trade remedy measures for which the industry strongly advocated.

Gold is regaining popularity, and with it, a resurgence in crucible furnace purchases. Gold has long maintained its market value despite its shifts in market saturation. This week’s headline, “Gold that could be worth €150 million discovered by miners in Ireland” gave gold enthusiasts renewed excitement in their search for the valuable metal. “Archaeologists Baffled by 2,000 Tiny Gold Spirals Discovered in Denmark” also sparked the imagination of gold hunters and miners when a half a pound of pure gold was found at an archaeological site over 1000 years old. Public interest was so high that in order to meet the demands of patrons the Skaelskor museum opened a special exhibit featuring the gold spirals. Western Australia has also seen new gold discoveries in its Gruyere mining province. These recent finds have led to an increase in crucible furnace purchases in gold processing areas including the one in Australia
Crucible furnaces have long been the pinnacle of gold melting for the precious metals industry. Gold has long been one of the world’s most highly sought-after minerals as it is one of the easiest metals to smelt and handle. Gold can be easily melted in a crucible furnace and is no-corrosive, non-reactive to most other elements and is highly malleable.
Since man first learned how to melt and process gold, it has proven to be a favorite precious metal for making coins and jewelry. With the help of a crucible furnace, gold is also now able to be used to manufacture electrical conductors, infrared shielding, and wiring and is even used on the circuit boards of most cell phones. Gold’s ability to be highly ductile and a great conductor of electricity make it a smart choice for electrical manufacturers.
Gold also possesses the ability to be pounded flat until the point of being transparent without losing its strength. Gold is able to be melted with or into other metals in a crucible furnace to create stronger alloys product while maintaining its highly-desired color and value.

A Car Bottom Furnace is one of the most versatile of all the industrial furnaces and is one of the most widely used unit types. Our customers use these furnaces for a variety of processes in their facilities including heat treating applications such as post welding, stress relieving and annealing.
Sales for Car Bottom Furnace models are on the rise as many of our customers are bringing their heat treating in-house. We decided to pole our customers’ applications as well as the most common industries to determine uses for our exceptional Car Bottom Furnaces.
Here are the Top 5 Uses for an Industrial Car Furnace:
- The number one most frequent application is heat-treating large or heavy welded fabrications like gear blanks, which are generally used in automotive and machine tool parts. Other popular heat-treating uses include industrial steel and aluminum mill applications like wire annealing, foil annealing and pre-rolling processes like pre-heating and reheating.
- The second most common use is homogenizing applications like aluminum logs, billets or plates.
- Forging processes come in 3rd for making parts used in manufacturing automotive, aerospace, oil drilling equipment and other capital equipment.
- Casting is the 4th most frequent use, most commonly using large steel and aluminum castings both expendable and non-expendable for manufacturing parts.
- Lastly is powder metallurgy which is particularly important for its unique ability to alter materials that are impossible to create by normal melting processes.
Car Bottom Furnace applications that did not make the top 5 list but deserve honorable mention include transformer drying and workpiece austempering. Transformer drying in a car bottom furnace can be done for both low frequency heating (vacuum drying) and vapour phase drying. These processes are important for the proper maintenance of any transformer. Workpiece austempering is a hardening process in which rapid quenching is performed during steel manufacturing in order to increase strength and ductility.
