China float glass manufacturer for Automobile Windshield glass processing

Ultra Clear Medium Aluminosilicate Electronic Float Glass(CHIYAN-M2) is an eco-friendly ultra clear alumino-silicate glass with certain strength.

Glass Type: Float glass

Car windshields are generally made of a large curved surface as a whole, and there is a certain arc up and down. This curved glass, whether from the processing process or from the fitting point of view, is a very high technical requirements of the product, because it involves the model, strength, heat insulation, assembly and many other issues.

Standard shipping Size:1300*1100mm (5th Generation)

Regular Thickness:

2.0mm 1.80mm 1.50mm 1.30mm

1.10mm 0.70mm 0.55mm

0.40mm 0.33mm 0.25mm

Note: The size can be customized according to customer's needs.

CHIYAN-M2’s 0.25~2.0mm thickness medium alumino-silicate glass has already been used in the market to meet a wide range of customers needs.

Application:
Float glass is widely used, divided into colored glass, float silver mirror, float glass/automobile windshield grade, float glass/all kinds of deep processing grade, float glass/scanner grade, float glass/coating grade, float glass/mirror grade. Among them, ultra-white float glass has a wide range of uses and broad market prospects, mainly used in high-grade architecture, high-grade glass processing and solar photovoltaic curtain wall fields, as well as high-grade glass furniture, decorative glass, imitation crystal products, lighting glass, precision electronics industry, special buildings, etc.

Product Composition

Ultra Clear Medium Aluminosilicate Glass achieves better stress and strain depth than ordinary soda-lime glass by increasing the Al₂O₃ content in the glass and increasing the ion exchange capacity.

Storage
Storage conditions: Temperature ≤30℃, humidity ≤65% (no condensation), shelf life is 6 months from the date of delivery.

Float glass is made by heating raw materials—silica sand, limestone, soda ash, and magnesium in a furnace. When melted, it’s then spread out over a sizable bed of molten tin. As it moves along rollers in the annealing oven during a controlled cooling process, this mixture slowly solidifies over the molten tin. From this point, a single, continuous smooth ribbon of glass emerges as below picture showed:
