The customization of spherical hot-bent glass involves several key points, and the following is a detailed summary of these points:
1. glass quality requirements
Raw material selection: flat glass with good quality should be selected as raw material to ensure that the glass is free of defects such as cracks, bubbles and inclusions.
Glass thickness: According to the use scenario and the required strength, choose the appropriate glass thickness. For spherical hot-bent glass, thicker glass is usually required to ensure its structural stability and strength.
Technical requirements for hot bending of 2.
Temperature control: During the hot bending process, the heating temperature and time need to be strictly controlled. In general, when the temperature of glass reaches about 600 ° C., it can be hot-bent by pressing and heating. Too low temperature may cause the glass to bend undesirably, while too high temperature may cause the glass to burn or crack.
Pressure control: During the heating process, appropriate external pressure needs to be applied to promote uniform deformation of the glass. The magnitude and direction of the pressure should be adjusted according to the shape and size of the glass to avoid tearing or breaking.
Heating and cooling speed: heating and cooling speed should be moderate, too fast or too slow may have an adverse effect on the glass. It should be ensured that the glass can be heated and cooled evenly during the heating and cooling process to avoid thermal stress and cracking.
3. mold making and positioning
Mold design: the mold design of spherical hot bending glass is very important. The shape, size and accuracy of the mold should meet customer needs and processing requirements. At the same time, the material of the mold should also have good heat resistance and wear resistance to ensure the service life and processing quality of the mold.
Positioning and fixing: During the hot bending process, ensure that the positioning between the glass and the mold is accurate and firmly fixed. This can be achieved by using tools such as dowel pins, clamps, etc. Inaccurate positioning or weak fixing may cause the glass to deform or break during hot bending.
4. annealing treatment
Annealing purpose: Annealing treatment is to eliminate the thermal stress and internal defects of the glass during the hot bending process, and to improve its strength and durability.
Annealing process: The annealing process includes three stages: heating, holding and cooling. The specific annealing process parameters should be determined according to the thickness, shape and heating temperature of the glass.
5. Safety and Quality Control
Safety measures: there are high temperature, high pressure and other dangerous factors in the process of hot bending glass. It shall be ensured that operators have appropriate safety knowledge and operation skills and wear necessary protective equipment. At the same time, the processing equipment should be inspected and maintained regularly to ensure its normal operation, safety and reliability.
Quality control: strict quality control should be carried out in all aspects of the processing process. Including raw material inspection, temperature control, pressure control, mold production and positioning, annealing treatment, etc. At the same time, finished product inspection and performance testing should be carried out to ensure that the processed spherical hot-bent glass meets customer requirements and standard specifications.
In summary, the processing customization of spherical hot-bending glass requires comprehensive consideration of multiple factors, including glass quality, hot-bending technical requirements, mold production and positioning, annealing treatment, and safety and quality control. Only by ensuring that these points are strictly followed and implemented can high-quality spherical hot-bent glass products be processed.
