Overview of the Ceramic Atomizer Core Production Process

Ceramic atomizing core, as a kind of electronic cigarette heating element, has been favored by many users in recent years, and is one of the common types of atomizing core. It makes the electronic cigarette a unique experience. 

1. Advantages of ceramic atomizing core 

1. Better taste: Ceramic atomizing core can usually provide a purer and smoother taste. Due to the heating characteristics of ceramics, it can heat the e-liquid more evenly, resulting in a more delicate smoke, which is a clear advantage for users who pursue high-quality taste. 

2. Reduce burnt smell: Ceramic materials can remain stable at high temperatures, unlike cotton core, which is easy to burn, so the generation of burnt smell is reduced during use. 

3. Long service life: Ceramic atomizing cores have high heat resistance and physical stability, and are not easily corroded by e-liquid, so their service life is usually longer than that of traditional cotton cores. 

2. Disadvantages of ceramic atomizing cores 

1. Long heating time: Compared with cotton cores, ceramic atomizing cores may take more time to reach the ideal heating temperature when they start heating. 

2. Higher cost: Due to the relatively high manufacturing cost and technical requirements of ceramic atomizing cores, this results in their market price being generally higher than that of traditional cotton cores. 

3. Taste transmission may be slower: Some users have reported that when ceramic atomizing cores switch different flavors of e-liquid, the previous flavors may remain for a long time, affecting the purity of the new flavors.

3. Production Process of Ceramic Atomization Cores

It usually includes the following steps:

1. Raw Material Preparation:

Select high-purity ceramic powders suitable for atomization applications, such as materials like aluminum oxide and zirconium oxide. These materials have good thermal stability and corrosion resistance.

2. Slurry Preparation:

Uniformly mix the ceramic powder with organic or inorganic binders and solvents to form a slurry with certain fluidity and plasticity. Other functional additives may also be added to this slurry to improve its electrical conductivity, oil absorption capacity, or porosity.

3. Molding Process:

Use methods such as thick film printing technology, slip casting, dry pressing, injection molding, etc. to coat or fill the slurry into specific molds, forming the basic shape and structure of the atomization core, including the porous ceramic layer and the heating element area.

4. Drying and Sintering:

After preliminary drying to remove most of the solvents, carry out high-temperature sintering treatment, causing the ceramic particles to melt and bond with each other, forming a dense ceramic body with a certain pore structure.

5. Deposition of the Conductive Layer:

For atomization cores that need to generate heat, one or more layers of conductive materials (such as metal films) are added to the surface of the sintered ceramic body through methods like sputtering, electroless plating, screen printing, etc., forming a resistance heating layer.

6. Cutting and Packaging:

After the production of the conductive layer is completed, precisely cut the ceramic atomization core according to the design requirements to ensure that the dimensions meet the standards, and package the completed atomization core with external connectors, such as installing electrode pins, insulating materials, etc.

7. Quality Inspection:

Conduct performance tests and quality control on the produced ceramic atomization cores, including resistance value detection, evaluation of heating efficiency, stability testing, and inspection of oil absorption and atomization effects.

8. Packaging and Out-of-Stock:

Dust-proof and anti-static treatments are carried out on the products that pass the inspection and then they are packaged. After that, they are put into storage and wait to be shipped to downstream e-cigarette manufacturers or other relevant industry customers.

Different manufacturers may adjust the specific production process flow according to their own technologies and market demands.
