What is the difference between manual blowing and machine blowing of glassware.

If it is a water cup: only see if the cup has a seam line and the wall thickness can be distinguished. The artificial blown cup generally has no seam line, the cup wall is thin, most of them have slight bubbles and streamlines, and the specifications are slightly different. The machine The blown cup wall is thicker, some have stitching lines, fewer bubbles, streamlines, and the same size.

If it is a goblet: in terms of domestic glassware, the mechanism is thick and thick, and the cup type is smaller and looks thicker (or stupid). The artificially blown cup is thin and quite thin. Fine, more styling, looks more refined, of course, there may be bubbles and streamlines.

If it is a goblet of a well-known foreign brand, the mechanism of the cup is better than manual blowing: thin, thin wall, no bubbles, streamline, shape and other aspects are not different from manual blowing, for those who really drink red wine Should be better.

Second, what is the blowing process of glassIt is one of the processes for making glassware.

The specific production method: the blower holds a hollow iron pipe with a length of about 1.5M, one end draws the glass liquid from the furnace (picking material), one end is the mouthpiece. Roll the spoon on the material plate (bowl). Blow the air to form a glass frit, blow it into a product in the touch, or blow it freely without the mold, then knock it off from the blow tube. Then cool it.

After picking up the material, roll and blow on the rolling plate (bowl) to form a glass frit, which is blown into the product in the mold; or it can be blown freely without mold, and then knocked off from the blow pipe. Repeatedly picking and rolling to gather enough material. When mechanically blowing, the glass liquid flows out from the glass melting furnace outlet, and the material is formed into a set weight and shape by the feeder, and cut into the initial mold to blow or Pressed into the initial shape, and then transferred into the molding die to blow the product. The blow-blowing method is blown into the initial type and then blown into the product, which is suitable for making small mouth vessels and bottles. Pressing into the initial type and then blowing the product into the weighing - Blowing method, suitable for making large mouth vessels and thin walled cans.
