Automatic insulating glass processing equipment is required for producing the refrigerated display cabinet doors

1. The cutting double-headed saw: Aluminum alloy and hard plastic are generally used for glass door frames. First, cut to the desired length and 45-degree angle with a chop saw. Four profile couplets form a frame. Because the gap between the two 45-degree angles is required to be free from concavities, cracks, and burrs, the precision requirements for the cutting saw are relatively high.

2. The CNC drilling and milling machine: This machine is used for processing various holes and grooves of glass door frames.

3. Glass washing  and drying machine: glass doors are generally composed of single-glass, double-layer insulating glass, and triple-layer insulating glass, but no matter what kind of glass door is made, the glass must be cleaned. Use Colet's glass washing machine to ensure that your glass is cleaned in place, free from stains and watermarks.

4. Insulating glass butyl rubber coating machine: To strengthen the thermal insulation of the glass door, the glass door should be made of insulating glass. This machine is used to apply sealing butyl glue to the aluminum strip spacer between the two layers of glass of the insulating glass door.

5. Insulating glass two-component sealant sealing machine: This machine is used for sealant sealing around the insulating glass door for the refrigerated display cabinet.

6. Insulating glass sealant coating rotary table: This machine is the auxiliary equipment of the two-component sealant sealng machine, which is convenient for workers to apply the sealing.

7. Insulating glass Inert gas inflator Equipment: This machine is used to fill inert gas such as argon for insulating glass doors for the refrigerated display cabinet.

8. Insulating glass aluminum spacer punching machine: This machine is used for punching the air-filling hole and exhaust hole before the insulating glass is filled with inert gas.

To achieve its beautiful and transparent effect, traditional refrigeration display cabinets often use glass doors. There are mainly three types of insulating glass doors commonly used in refrigerators in the existing market, as follows:

1. The first method is a metal insulating strip-type glass door with double-layer ordinary glass. Due to the temperature difference between the inside and outside of the cabinet, this kind of insulating glass door will inevitably condense or frost on the glass door, causing the glass door to become blurred. The items in the cabinet cannot be seen clearly, affecting its transparency and aesthetics.

2. The second method is that the outer glass is coated with a metal conductive film. Metal spacers are used between the double-layer glass of the insulating glass. Silver paste lines are added on both sides of the glass coated with conductive film. The silver paste lines on both sides of the glass are connected to the power supply to heat the glass to solve the problem of condensation and frost. However, because the metal insulating strip has strong conductivity when using it, the conductive film on the glass at the metal insulating strip must be removed. Metal insulating strips lead to poor sealing of this type of insulating glass door. The inert gas cannot be retained for a long time in the insulated cavity, and the energy-saving effect of the glass door is poor, which eventually leads to the increased energy consumption of the product.

3. The third method is similar to the second method, except that the metal spacer is changed to a PVC spacer. Because the PVC material is an insulator, the conductive film does not need to be removed at the contact part with the conductive film. The silver paste belt can also be placed outside the spacer, and the insulated cavity can be filled with inert gas. However, the spacer in this process is a plug-in type. The four corners of the spacer are connected by plug-ins.
1. Material selection: Choose high-quality glass materials, such as tempered glass or laminated glass, and processed insulating glass. This ensures the durability and safety of the custom wine glass door.

2. Visibility and privacy: Consider the transparency of the glass door, and determine the degree of transparency of the glass according to personal preferences and usage needs. If you wish to display your wine collection, go for a clearer glass, or if you're more concerned about protecting your wine from light and temperature, go for a glass with thermal properties.

3. Dimensions and installation: Measure the size of the wine cabinet correctly to ensure that the customized glass door can be installed perfectly. Also consider the opening method of the door, such as sliding door, revolving door, or flip door, to ensure that it can be easily opened and closed in a limited space.

4. Safety considerations: choose glass with good explosion-proof, anti-ultraviolet, and sound insulation functions to ensure the safety and protection of red wine collection.

5. Cleaning and maintenance: Glass doors are easy to leave fingerprints and stains, so choose easy-to-clean glass, such as anti-fingerprint coating or easy-to-clean coating. Also, take care to clean and maintain your glass door regularly to ensure it looks tidy.

6. Lighting design: The lighting design in the wine cabinet can enhance the display effect of red wine. You can consider setting up appropriate lighting around the glass door to highlight the beauty of red wine.

In short, when customizing the glass door of the wine cabinet, you need to pay attention to material selection, visibility and privacy, size and installation, safety, cleaning and maintenance, and lighting design to meet your needs and improve the functionality and aesthetics of the wine cabinet.

When the glass tempering furnace is tempered, the parameter setting of the tempering furnace should pay attention to the following points:

1. For glass with holes and grooves, the heating time of the glass tempering furnace should be increased by 2.5% to 5% compared with a glass of the same specification.

2. For glass with sharp corners: the heating time of glass with an angle of less than 30° in the heating furnace is 2.5% to 5% shorter than that of ordinary glass. The part absorbs heat too quickly and causes bending.

3. For embossed glass: when the glass is placed, the uneven surface is generally facing up. To avoid ripples caused by excessive heating time, the uneven surface is sometimes placed downward. The heating time should be determined according to the thickest part of the glass, and the blowing pressure is also the same.

4. Glass tempering furnace for heat-absorbing glass: the heating time is generally reduced by 5% compared with ordinary glass.

5. For coated glass and heat-reflecting glass: to protect the film surface, the coated surface should face up, and the bottom temperature and heating time should be increased by 2.5% to 10% compared with an ordinary glass of the same thickness.

6. For glazed glass or enamelled-surface glass: it must be dry before entering the tempering furnace. The upper and lower temperatures are generally set at about 700°C. If the glass is bent, the wind pressure must be adjusted appropriately. The heating equilibrium pressure can be reduced by about 50%, and the heating time also has a certain relationship with the color of the glaze.

For the tempering of the glass tempering furnace, after understanding the above tempering parameter setting requirements, it is necessary to conduct a tempering test of a small amount of glass before mass production and adjust the relevant tempering data according to the actual situation to ensure the tempering quality of the produced glass.
