Aohong Special Glass Manufacturing Co., Ltd


Liquid Level Gauge Glass - according to DIN 7081,DIN 7080 Manufacturing Process Steps

We are a modern high-tech manufacturing enterprise that specializes in producing and selling level gauge glass products. We have successfully obtained ISO9001:2008 quality management system certification. Our product range includes Reflex Gauge Glass and Transparent Flat Gauge Glass (according to DIN7081), Round sight Glass (according to DIN 7080).

In our production process, we follow the following steps:

Gauge glass detection

1, Glass rod raw material Entry

The production process begins with the careful selection of high-quality glass rod raw materials. These raw materials serve as the base materials for standard glass production and have a significant impact on the strength and clarity of the final product.

Glass blank pressing

2, Glass blank pressing

The glass rods are softened by heat and then pressed into shape in a precision mold to create a blank glass.

Gauge Glass Thinning

3, Glass thinning

In order to achieve the desired thickness, the blank glass is subjected to a precise thinning process. Advanced machinery and technology ensure uniform thinning, which contributes to the overall flatness and parallelism of the glass.

Advanced Glass Chamfering

4, Advanced Glass Chamfering

Chamfering is a critical step in glass processing, especially for instrument glass, as it minimizes the risk of stress concentrations and potential weak spots. Advanced chamfering technology creates smooth, rounded edges that increase glass safety, durability and reduce the possibility of breakage.

Glass double-sided grinding

5, Glass double-sided grinding

Carefully grind both sides of the glass to ensure uniform thickness, eliminate any irregularities, improve glass flatness and parallelism, and remove burrs.

Double or Single-Sided Polishing

6, Double or Single-Sided Polishing

Polishing is a critical step in further refining the surface of gauge glass. Specialized polishing techniques are used to remove burrs and scratches from the glass, resulting in a flawless and optically clear surface.

7, Cleaning Gauge Glass

Before the final stage of production (tempering), instrument glass is thoroughly cleaned to remove any particles or residues that could affect its performance or impair safety during use.

Tempered Liquid Level Gauge Glass

8,Tempered Liquid Level Gauge Glass

The last step is to temper the gauge glass, which improves the strength, impact resistance, temperature resistance and abrasion resistance of the glass by forming compressive stress on the glass surface, making it suitable for harsh industrial environments.

Printing and packaging

9,Printing and packaging

According to customer requirements, we can print trademarks, dates, etc. on the glass, customize labels on the cartons, and make wooden boxes as needed to ensure the safe transportation of the glass.

Meticulous production process and provide a comprehensive range of instrument glass types, and Aohong can be customized to meet the needs of customers around the world and in various industries. ISO9001:2008 quality management system certification further strengthens their commitment to quality, safety and customer satisfaction. The company focuses on continuous improvement and strives to meet and exceed customer expectations.
