Overview of the ceramic atomising core production process

Ceramic atomising core, as a kind of Electronic Cigarette heating element, has been favoured by many users in recent years, and is one of the common atomising core types. It makes use of the characteristics of ceramic materials to give electronic cigarettes a unique experience.
First, the advantages of ceramic atomising core
1. Better taste: ceramic atomiser cartridges usually provide a purer and smoother taste. Due to the heating properties of ceramic, it can heat the oil more evenly, resulting in a more delicate smoke, which is a clear advantage for users who are looking for a high-quality taste.
2. Reduced burnt flavour: Ceramic material is able to remain stable at high temperatures and does not burn as easily as cotton wicks, thus reducing the production of burnt flavour during use.
3. Longer lifespan: ceramic atomising cores are more heat resistant and physically stable, and are not easily corroded by tobacco oil, so they usually have a longer lifespan compared to traditional cotton cores.
Second, ceramic atomising core disadvantages
1. Longer heating time: Compared with cotton wicks, ceramic wicks may take more time to reach the ideal heating temperature when they start to heat up.
2. Higher cost: Due to the relatively high manufacturing cost and technical requirements of ceramic wicks, this results in a market price that is usually higher than that of traditional cotton wicks.
3. Flavour transfer may be slower: some users have reported that when switching between different flavours of vape oils with ceramic Atomizer cores, the previous flavour may remain for a longer period of time, affecting the purity of the new flavour.

Third, the production process of ceramic atomising core
Usually includes the following steps:
1. Raw material preparation.
Select high-purity ceramic powders suitable for atomisation applications, such as alumina, zirconia and other materials, which have good thermal stability and corrosion resistance.
2. Slurry Preparation.
Mix the ceramic powder with organic or inorganic binder and solvent to form a slurry with certain fluidity and plasticity. Other functional additives may be added to the slurry to improve its electrical conductivity, oil absorption or porosity.
3.Moulding process.
The slurry is coated or filled into a specific mould using thick-film printing techniques, slurry moulding, dry press moulding, injection moulding, etc. to form the basic shape and structure of the atomised core, including the porous ceramic layer and the heating element area.
4. Drying and Sintering.
After initial drying to remove most of the solvent, and then high temperature sintering treatment, so that the ceramic particles melt and bonding between the ceramic particles to form a dense and have a certain pore structure of the ceramic body
5. Conductive layer deposition.
For the need to heat the atomised core, sintered ceramic body surface by sputtering, chemical plating, screen printing and other methods to add one or more layers of conductive materials (eg, metal film), the formation of resistive heating layer.
6. Cutting and encapsulation.
After completing the production of conductive layer, according to the design requirements of the ceramic atomised core for precision cutting, to ensure that the size of the standard, and will be completed with the atomised core and external connectors for encapsulation, such as the installation of the electrode pins, insulating materials and so on.
7.Quality Inspection.
Carry out performance testing and quality control on the produced ceramic atomiser core, including resistance value testing, heat generation efficiency evaluation, stability testing, and oil absorption and atomisation effect inspection.
8.Packaging and warehousing.
Qualified products are dustproof and anti-static treated and packaged, and then warehoused for shipment to downstream e-cigarette manufacturers or other related industries.
