1.Precision mold technology

The unique shape of perfume bottles (such as curved bottles and special-shaped bottle mouths) relies on precision molds. Precision mold technology determines the shape, size and detail accuracy of the bottle.Through high-precision CNC machine tools and computer-aided design, the mold can achieve complex patterns and curves. The mold is made using CNC machining technology.The accuracy can be controlled within ±0.01mm, which can accurately restore the design details.Whether it is a square bottle with sharp edges or a round bottle with smooth curves, the dimensions can be guaranteed to be consistent between batches.

2.Automated production and testing

The automated assembly line can achieve seamless connection between glass melting, blowing, forming, and cooling and setting, and its production efficiency is more than 3 times higher than traditional manual methods.The automated inspection system uses visual sensors and artificial intelligence to accurately identify surface defects such as scratches, bubbles, and impurities;Ensure that each perfume bottle meets strict quality standards.

3.Environmentally friendly surface treatment technology

The use of water-based paint, UV curing technology and recyclable materials reduces pollution to the environment and is an important development direction of the fragrance bottle industry.Environmental protection technologies also include wastewater treatment from electroplating and spraying processes, ensuring that the entire manufacturing chain meets green standards.The application of biodegradable varnish allows the protective layer on the surface of the perfume glass bottle to degrade naturally after disposal, combining high-end aesthetics with environmental protection, in line with the current sustainable brand concept.

4.Sealing technology

The main sealing structure used on the market now is "silicone sealing ring + thread locking" double sealing structure:Combined with ultrasonic welding and pressure testing, the silicone sealing ring is made of food-grade material and has a 99% fit with the bottle mouth.The thread design uses precise calculation of the pitch to ensure that the bottle cap will not loosen after being tightened, and the bottle mouth is laser sealed.This technology not only extends the shelf life of the perfume, but also maintains its original fragrance and enhances the user experience.

5.Filling and capping technology

The filling and capping of perfume glass bottles must be carried out in a sterile environment.Filling and capping technology involves the precise injection of perfume and the secure sealing of bottle caps, usually using fully automatic filling machines and capping equipment.These technologies enable precise control of fill volumes to avoid spillage or waste, while ensuring tight and consistent capping through a torque control system.The fully automatic filling machine adopts the negative pressure filling principle with an accuracy of ±0.1ml, which avoids perfume overflow and waste, while reducing contact with air and preventing perfume oxidation;The capping process uses a torque control system to precisely control the tightening force of the bottle cap (usually 0.8-1.2N·m), ensuring a good seal while making it easy for consumers to open and close the bottle.Some high-end perfume glass bottles are also equipped with ultrasonic sealing technology, which uses high-frequency vibration to achieve a seamless fit between the bottle cap and the bottle body, further improving leak-proof and anti-counterfeiting performance.
