The production process of cosmetics packaging essential oil bottle glass is generally: the batching workshop prepares the required batch materials, which are transported by the conveying equipment to the kiln head silo of the melting workshop. Then it is added to the glass furnace by the feeder, and melted into the molten glass at a high temperature of about 1450°C. The molten glass is then supplied to the molding equipment (bottle making machine, etc.) from the feeder to the required essential oil bottles through the feeding channel. Then the product is sent to the annealing furnace for annealing to remove stress by bottle conveying, bottle pushing machine, etc. After the quality inspection, the qualified essential oil bottle products are packaged, stored, and shipped out of the factory.
Pre-processing of raw materials. Break the lumpy raw materials to dry the wet raw materials, and remove the iron from the iron-containing raw materials to ensure the quality of the glass essential oil bottle.
Melting. Glass bottle is a traditional essential oil bottle packaging container, and glass is also a kind of packaging material with a long history. The glass batch material is heated at high temperature (1550~1600 degrees) in a pool furnace or a pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.
Forming. Put the liquid glass into the mold to make the essential oil bottle glass product of the required shape.
Heat treatment. Through annealing, quenching, and other processes, the internal stress, phase separation, or crystallization of the essential oil bottle glass material is cleaned or generated, and the structural state of the glass is changed.
