Manufacturing process of glass kettle,glass pot with lid .
We often see glass teapots in our lives, and glass teapots can be divided into ordinary glass teapots and heat-resistant glass teapots. Ordinary glass teapot, exquisite and beautiful, made of ordinary glass, heat resistance of 100℃-120℃. Heat-resistant glass teapots are made of high borosilicate glass. They are generally blown by hand. The yield is low and the price is more expensive than ordinary glass.
Generally, it can be boiled directly, and the temperature resistance is generally about 150 ℃. It is suitable for direct boiling of black tea, coffee, milk and other beverages and foods, and also suitable for brewing various green tea and scented tea with boiling water.
The glass teapot can be blown manually or pressed by a machine.
Manual blowing refers to the use of a stainless steel hollow tube to pick an appropriate amount of high-temperature molten glass solution, and then blow at the other end of the blowing tube to blow it into a spherical shape, and then put it into the mold and continue to blow it into a shape that matches the mold. After cooling down , Open the mold, cut, edging, trace gold and other series of processing after it comes out, which is the finished product afterwards. Manual blowing greatly enriches the shape of the glass tea set and embodies its artistry.
Machine pressing means that the pressing machine mold is fixed on the turntable, and the high temperature melted glass is dripped into the mold through a barrel, and then the product is pressed down when it is turned down, then it is manually taken out, annealed, and then it comes out It's the finished product.
