In the field of glass deep processing, annealing and tempering are two of the most common heat treatment processes. Many customers often ask: Since there are annealing furnaces, why choose a tempering furnace? The answer is simple: as building safety standards and market demand continue to rise, tempered glass is gradually replacing annealed glass as the mainstream.

But more importantly—not all tempering furnaces are the same. Choosing a high-performance, energy-efficient, and stable tempering furnace is the key to truly enhancing competitiveness. Today, we will not only explain the difference between tempering and annealing but also show you: why more and more customers choose Xinglass tempering furnaces.

I. Annealing vs. Tempering: Stability vs. Strength

Annealing
Annealed glass is slowly cooled to eliminate internal stress. Its performance is stable, but its strength is similar to ordinary float glass.
       Suitable for low-risk applications such as interior partitions, laminated glass, and coated glass.

Tempering
Tempered glass is rapidly cooled to form compressive stress on the surface, increasing strength 4–5 times, with heat resistance above 300℃. When broken, it shatters into blunt granules, making it much safer.
       Widely used in curtain walls, household appliances, automobiles, and photovoltaics.

In short:

Annealing = making glass more stable

Tempering = making glass stronger

II. Why Choose a Tempering Furnace?

Meets Safety Standards
Modern architecture and home appliance industries require high safety standards. Tempered glass has become mandatory.

Enhances Competitiveness
High-performance tempered glass opens doors to more markets and high-value orders.

Wider Application
From skyscraper curtain walls to photovoltaic panels, industrial equipment to vehicles, tempered glass is everywhere.

Industry Trend
Energy-saving, safety, and durability are the mainstream of glass processing.
