Manufacturer Process of Ceramic Infrared Heater

The manufacturing process of ceramic infrared heaters involves several stages, from raw material preparation to the final assembly of the heating elements. 

1. Raw Material Selection:

The process begins with the selection of high-quality ceramic materials, often alumina (aluminum oxide) or silicon carbide. These materials are chosen for their excellent thermal conductivity and electrical insulation properties.

 

2. Powder Preparation:

The selected ceramic materials are crushed into fine powders and carefully blended to achieve the desired composition and consistency.

 

3. Shaping:

The powdered ceramic material is mixed with binders and additives to create a malleable mixture. This mixture is then shaped into the desired form, which could be flat, tubular, or custom-designed shapes, depending on the type of ceramic infrared heater being produced.

 

4. Drying:

The formed ceramic elements are dried to remove excess moisture and binders. This step is essential to ensure the stability of the ceramic structure.

 

5. Firing:

The dried ceramic elements are fired in high-temperature kilns. During firing, the ceramic material undergoes sintering, which involves heating it to high temperatures to fuse the particles together, resulting in a dense and thermally conductive structure.

 

6. Coating (Optional):

Some ceramic infrared heaters are coated with a reflective layer or an emissive coating to enhance their infrared radiation efficiency. These coatings may be applied to the ceramic surface as needed.

 

7. Wire Element Insertion:

In cases where the ceramic infrared heater uses wire heating elements, these elements are inserted into the ceramic body. The wire elements are usually made of materials like nichrome or iron-chromium-aluminum alloys.

 

8. Electrical Connections:

Electrical terminals or connectors are attached to the heating elements to allow for easy electrical connection when the heater is installed.

 

9. Quality Control:

Throughout the manufacturing process, quality control checks are performed to ensure that the heating elements meet the specified dimensions and performance criteria.

 

10. Packaging:

Once the heaters pass quality control and testing, they are packaged for shipment to customers.
