First of all, it is necessary to design and manufacture the mold. The glass raw material is made of quartz sand as the main raw material, and other auxiliary materials are dissolved into a liquid state at a high temperature, and then injected into a mold, cooled, cut, and tempered to form a glass bottle. Glass bottles generally have a rigid logo, and the logo is also made of a mold shape. The forming of glass bottles can be divided into three types: manual blowing, mechanical blowing, and extrusion. Glass bottles can be divided into the following categories according to their composition:
Second, lead glass
The third is boron bismuth glass
The main raw materials for glass bottles are natural ore, quartz, caustic soda, limestone and the like. Glass bottles are highly transparent and resistant to corrosion and do not change in material properties when in contact with most chemicals. The manufacturing process is simple, the shape is free and changeable, the hardness is large, heat-resistant, clean, easy to clean, and has the characteristics of being reusable. Glass bottles are widely used as packaging materials for food, oil, alcohol, beverages, condiments, cosmetics, and liquid chemical products. However, glass bottles also have their shortcomings, such as heavyweight, high transportation and storage costs, and low impact resistance.
Characteristics and types of glass bottles: Glass bottles are the main packaging containers for food, medicine, and chemical industries. They have good chemical stability; easy to seal, good air tightness, transparent, can be observed from the outside; the storage performance is good; the surface is smooth, easy to disinfect and sterilize; the shape is beautiful, the decoration is colorful; there is certain machinery The strength can withstand the pressure inside the bottle and the external force during transportation; the raw materials are widely distributed and the price is low. The disadvantage is that the quality is large (the mass to capacity ratio is large), the brittleness is large, and it is brittle. However, with the new technology of thin-walled lightweight and physicochemical tempering, these shortcomings have been significantly improved, so that the glass bottles can be increased year by year under the fierce competition with plastics, iron, and iron cans.
There are a wide variety of glass bottles, from small bottles of 1ML to large bottles of dozens of liters, from round, square, to shaped and handle bottles, from clear, amber, green, blue, black shaded bottles and opaque The opaque glass bottles, etc., are too numerous to mention. In terms of manufacturing process, glass bottles are generally divided into two types: molded bottles (using model bottles) and control bottles (with glass bottles). Molded bottles are divided into two types: large-mouth bottles (both mouth diameters above 30MM) and small-mouth bottles. The former is used to hold powder, block and paste items, and the latter is used to hold liquids. According to the bottle mouth form, it is divided into cork bottle mouth, threaded bottle mouth, crown cap bottle mouth, rolling bottle mouth frosted bottle mouth and so on. According to the use situation, it is divided into "one-time bottle" which is used once and discarded, and "recycled bottle" which is used for multiple turns. According to the classification of the contents, it can be divided into wine bottles, beverage bottles, oil bottles, canned bottles, acid bottles, medicine bottles, reagent bottles, infusion bottles, cosmetic bottles and the like.
