How is glassware blown into shape

- Aug 21, 2018-

There are two ways of manual and mechanical blow molding. In the case of manual molding, the hand-held blow pipe is picked up from the inside of the crucible or the kiln take-up port, and blown into a shape in a metal mold or a wood mold. The smooth circular product is subjected to a rotary blowing method; the surface has a convex or concave pattern or a shape in which the shape is not circular, and the static blowing method is used. First, pick a colorless material and blow it into a small bubble, and then use a small bubble to pick a color material or a blister-blown shape called a nesting material. The color fusible granules are immersed in the turbid nesting material, and the natural color flow of each color can be blown into a natural ware vessel; the opaque material is smeared on the color material, and can be blown into a drawing vessel. Mechanical forming is used to blow large quantities of products. After the blowing machine receives the material, the automatic iron mold is blown into a shape, and after the mold is removed, the cap is removed to form a vessel. Press-blow molding can also be used to first punch the material into small bubbles (formation) and continue to blow into a shape. It is more efficient and of better quality than a simple blower.
