Judging the shaping method According to the characteristics of the shape and size of different models of glass, you can choose a variety of stereotypes such as tgk heat gun wet roasting, heat gun target dry roasting, dry and heat gun target wet combination, pull and shape.



A. Wet roasting and setting: use the scraper and tgk heat gun for warming and pressing. (For glass with less curvature) Advantages: The diaphragm is heated quickly and can be shaped quickly. The disadvantage is that the glass is heated at a higher temperature and the glass is broken. The shrinkage range of the diaphragm is small and the uneven shrinkage is difficult to construct. It is difficult to cooperate with the heat gun target and it is easy to produce offset.



B. Dry roasting and setting: use a tgk heat gun to heat the surface of the diaphragm to form a shrinkage, and then mix it with a wet roasting. (For models with a thickness of less than 3Mil for any difficulty) Advantages: The glass is less heated and does not cause glass breakage; the diaphragm shrinks in a wide range and the shrinkage is uniform. The construction is convenient and quick and easy; the operation does not require the scraper to match. Printed. Disadvantages: It is difficult to judge the degree of shrinkage of the diaphragm when heating, and the wet method should be used after the diaphragm shrinks, and the steps are more complicated.



C. Dry and wet combination setting: use a tgk heat gun to heat the surface of the diaphragm to form a shrinkage and match the shape of the scraper. (For models with a thickness of less than 3Mil for any difficulty) Advantages: The glass is less heated and less likely to cause glass breakage; the diaphragm has a large shrinkage range and uniform shrinkage. The construction is convenient and quick and easy; Disadvantages: If the scraper is combined with the tgk heat gun, if it is not well matched, it will be easy to produce offset, and the dry and wet amount of glass is required.



D. Pulling and setting: Using the principle of shrinkage of the diaphragm, a large area of the surface of the diaphragm is heated by a tgk heat gun to form a contraction shape. (For diaphragms with better lateral shrinkage) Advantages: The diaphragm is heated to a high degree, the shrinkage range of the diaphragm is larger and uniform, and the construction is convenient and quick and easy; the operation does not require the scraper to cooperate without folding, and the operation can be fixed once. Disadvantages: It is difficult to control the temperature when the diaphragm is heated, and the diaphragm is likely to cause excessive shrinkage; it requires mature operation experience.
