Step-by-step glass bottle making
Modern Manufacturing Process, 300,000 Glass Bottles A Day
Cullet
Before Manufacturing Process.the raw materials for making glass bottles are sand, soda ash, limestone and broken glass mixed in a certain proportion to make soda lime glass
Heating Furnace
The raw material is subjected to a high temperature of about 1600°C in a heating furnace. The water evaporates, the organic matter is burned off, and the rest of the mixture melts to form molten glass.Can handle hundreds of tons of cullet a day
Molding Process
As each drop falls into a series of molds, the final product begins to take shape in the molding machine. Compressed air blows the droplets into shape and expands them into a glass container (the final shape is obtained by the blow-blow method)
Annealing Processes
Manufacturing process key process, the glass bottles are cooled during transport before entering the annealing furnace. This is a long kiln with controlled temperature. In it, the glass bottle is slowly reheated and then gradually cooled again before entering the packaging stage
Inspecting Glass Bottles
Each glass bottle goes through a series of checks to ensure it meets the highest factory standards. Experts also manually and visually inspect random samples to ensure quality.
Surface Treatment
After the glass bottle is finished, deep processing. They can be used for decoration, labels, and even scuff protection.

Screen Printing、Electroplating
Frosting、Embossing
