The use of tempered glass has grown dramatically over the years due to its use as phone and computer screens. Tempered glass was designed to be safer than other types of glass. The heat treatment process that is used for tempered glass is what strengthens the glass, making it safer to use. In order to create tempered glass, you will need to invest in a tempering furnace. For many glass fabrication companies, this is one of the largest investments they will make.

What is a Tempering Furnace?

A tempering furnace, sometimes called a tempering oven, is an industrial oven that uses heating technology to strengthen pieces of glass which makes them safer to use. The flat glass is placed on ceramic rollers that slowly move the glass through the radiant heaters and hot air jets. The glass then continues to roll through the furnace to be cooled which enhances its durability. The compression of the glass in the tempering oven makes the glass more flexible which allows the glass to break into small granular chunks instead of sharp pieces that can cause serious injury. 

The Different Tempering Ovens Offered by Matodi

At Matodi, we have partnered with Keraglass to bring three different types of tempering furnaces to you. The type of oven you need will depend on what you are creating the tempered glass for. 

Heat Soak Test Oven

Heat soak testing is highly recommended for any tempered glass that is designed to be used for exterior application, especially if the glass will be in an environment where there are frequent temperature changes. The heat soak process is used for this because it minimizes the risk of unexpected breakage that is typically caused by nickel sulfide inclusions. 

Bending and Tempering Oven One Way

A bending and tempering oven is used for horizontal bending, also known as lengthwise bending, or crosswise bending. Their uses can vary, but they are commonly used for interior glass pieces. 

Continuous Tempering Furnace

A continuous heat treatment furnace is typically used for large pieces of glass, such as glass for automobiles or appliances as well as for reheating semi-finished glass. The glass will pass through three heat-treatment zones before exiting the tempering oven. 

How To Determine The Right Tempering Furnace For You

Our expert sales team will walk you through the different options of tempering furnaces we have to offer, including the benefits and features of each, to help you land on the tempering oven that will best meet your needs. To give you an idea of the criteria we use, we start by identifying the following first:

Floor Space – As with most flat glass fabricating equipment, the machines come in a variety of sizes. The amount of space you plan to dedicate to the tempering oven will be a huge factor in determining which ovens you can choose from. We also recommend you take into consideration the amount of space that will be designated for the temporary storage of the tempered glass. This is crucial to ensure you are not losing any loading and unloading space around the tempering oven. 

Capacity – When deciding on a tempering furnace, we recommend the capacity of the glass tempering furnace you choose should match what you estimate for your annual production output. Once this is determined, our professional sales team will be able to narrow down your options for you. 

Power Load – Depending on the flat glass you plan to be working with, you will require different installed power. If you need a tempering furnace that requires a high power load (some tempering furnaces have installed power of 2400kw or more). Our sales team can help you determine if your existing transformer will be enough or if you need to look into expanding the capabilities to meet the output of the tempering oven you need.

For additional information regarding our tempering furnaces, you can contact our sales team at 336-668-2300 to get all of your questions answered. Our sales team will do everything to make sure you choose a tempering oven that will work best for your flat glass production company.
