High Strength 300mm Glass Shelf For Frigidaire Refrigerator

High Strength Toughened Tempered Glass For Refrigerator / Freezer Shelf

Description of toughened tempered glass:

Toughened tempered glass is thermally stronger than the normal glass. The glass undergoes intense stress due to which, the strength of glass increases. This glass is made through thermal tempering process where the annealed glass is heated at or above 720 degrees and soon after it reaches the heating point, cooling process is performed. The glass thus becomes strong and stressed.

Process of toughened tempered glass​:

Tempered glass is a type of glass with even compressive stress on the surface which is made by heating float glass to nearly softening point and then cooling it down rapidly by air. During the instant cooling process, the exterior of glass is solidified due to rapid cooling while the interior of the glass is cooled down relatively slowly. The process will bring the glass surface compressive stress and the interior tensile stress which can improve the mechanical strength of glass by germination and result in good thermal stability.

Advantages of toughened tempered glass:

Good safety: the raw materials of tempered glass generally contain less impurities, and the fine control in the melting process of raw materials makes the ultra white glass have more uniform composition than ordinary glass, and its internal impurities are less, thus greatly reducing the possibility of self explosion after tempering. When the toughened glass is damaged by external force, the fragments will become small particles with obtuse angle similar to honeycomb, which is not easy to cause serious injury to human body. Even if the environment in the kitchen is bad, the toughened glass with stable properties will not cause accidents.
High color consistency: because the iron content in the raw material is only 1 / 10 or even lower than that of ordinary glass, the toughened glass has less absorption in the green band of visible light compared with ordinary glass, which ensures the consistency of glass color. Compared with ordinary glass, toughened glass has less absorption in the red and purple band of visible light. Ensure that the glass does not change color. In this way, if the kitchen appliances use toughened glass, it will not change due to the changing environment of the kitchen. It can maintain a brand new appearance and maintain the operation of the internal machines of the kitchen appliances.

Quality Inspection process
1, When the first 100 pieces of finished products are packed, the quality inspector shall inspect them at the inspection point of finished products.
2, The product will be inspected two times casually every shift.
3, Before the product is packaged or after the finished product is repaired, the quality inspector shall inspect it at the finished product inspection point.
4, After the product is packaged, the quality inspector will inspect it at the finished product inspection point.
5, If the finished product is stored for more than one month or for other special reasons, the warehouse administrator shall inform the quality inspector on duty to inspect it at the delivery site (visual inspection according to the standard and packaging scheme is in conformity).

FAQ

Q: What's the cut hole effect?
A: It depends on different thickness and for thick glass; we usually use water jet + CNC.

For thin glass, we use CNC for cut hole to make sure no breakage chips exist from hole edge.

Q: Is irregular shape glass available?
A: No problem because we will use shape cutting machine + CNC to make sure about the quality.

Q: How's the silk print effect?
A: Feihong received lots of praise in silk print quality base on import paints + auto silk print machine + dust free room.
Available in high temperature silk print(The paint melt into glass) and low temperature paint(Pass adhesion test).

Q: What's the edge treatment could meet?
A: We could make direct cut(cut chips, cheapest), fine grinded(CNC) and polish edges base on your need.
The chamfer / radius could be set.
