How to Start a Tempered Glass Business? [Investment Details]

Accessories for smartphones, such as tempered glass, are quite high in demand. These are manufactured in high-temperature machines that rapidly heat and cool glass. Hardness tests, breaking tests, and dimension checks must all be passed before the tempered glass can be used. Silicon, extra safety, and glue are also used in the tempered glass. The glue that binds the tempered glass to the smartphone screen is an essential part of the manufacturing process.

Of course, a tempered glass manufacturing company is one of many businesses that can be started in any part of the world, and the business owner can still tap into the global market by simply exporting the goods. There is no need to rent an office. Tempered glass production generates about Rs 3 to 4 lakh in monthly revenue, which makes it one of the best innovative business ideas.

The safety and strength of tempered glass make it easier to use in a variety of demanding applications. It is very simple to start a mobile Tempered Glass company. You can start a Tempered Glass Manufacturing Business from the comfort of your own home.

In this article, we will walk you through the process of tempering glass, the investment requirements, and so on.

What is tempered glass?

Toughened or tempered glass is a form of safety glass that has been strengthened by regulated thermal or chemical treatments in comparison to ordinary glass. When tempered glass is broken, the tempering causes controlled internal pressures, making the glass crumble into small granular fragments rather than splintering into jagged shards. The granular chunks have a lower chance of causing damage.

Glass is a naturally brittle material. It goes through a tempering phase to improve its functional properties and operational protection. Tempering, also known as toughening, is a process that involves heating glass to extremely high temperatures to reinforce it and make it more resistant to breakage.

After toughening, the bit becomes extremely heat and shock-resistant. Tempered glass is four to five times stronger than annealed glass when it comes to breaking resistance.

Process of tempering glass

This unique business idea has a specific process through which it undergoes. The process is specified as under:

Step 1: Float glass is the starting point for all toughened glass. The glass is checked for imperfections before it is tempered. Float glass can break during toughening due to bubbles, inclusions, and cracks. As a result, if any signs of these defects are discovered, the glass cannot be tempered.

Step 2: Before toughening, it must first be cut to the desired form, as cutting or etching the finished product in its toughened state is impossible. The edges are smoothed after cutting, and any burrs formed during etching or cutting are removed.

Step 3: The float glass is thoroughly cleaned to extract all of the glass grains accumulated during the sanding process. This also means that dirt and other taints are kept at bay so they do not interfere in the process.

Step 4: The surface of the float glass is heated to over 600 degrees Celsius as it passes through a furnace during the tempering process. Some manufacturers heat the glass above 720 degrees Celsius, which is its annealing stage.

Step 5: After quenching with a high-pressure blast of air for three to ten seconds at different angles, the scorching glass is rapidly cooled. Tensile stresses build up temporarily in the internal zone of the glass as it cools and shrinks, while surface stresses grow as a result. These compressive stresses gradually increase the glass's strength, making it more difficult to crack.
