Manufacturing Process of Ceramic Fiber Product

1. Preparation of Raw Materials 2. Form of Ceramic Fiber 3. Mold Ceramic Fiber Products 4. Package and Delivery
The process begins with the preparation of raw materials. The main components are alumina and silica, which are typically derived from minerals such as aluminium bauxite and quartz. Besides that, these raw materials undergo crushing, grinding and mixing to achieve the desired chemical composition and consistency.

  • Strict quality control on raw materials;
  • Advanced processing equipment for raw materials;
After preparing the raw materials, employees will process them to ceramic fiber. There are two common methods for forming ceramic fibers:

  • Spinning: melting the raw materials at high temperatures and then spun into fine fibers using centrifugal force or air blowing techniques. Workers need to collect the fibers on a rotating drum or a collection device, forming a fibrous mat.
  • Blowing: in the blowing process, the molten raw materials will force through spinnerets or nozzles, where cool them by air or gas streams. This results in the formation of fine ceramic fibers.
When it comes to the molding system, it will form ceramic fibers depending on the desired application. Besides, some common forms of ceramic fiber products include blankets, boards, modules, papers, cloths, ropes, tubes and wool. Then it comes to compressing, layer or weaving of ceramic fiber products to achieve the desired thickness, density, and shape.

  • Precise molding system;
  • Highly automatic equipment allows efficient production;
After molding ceramic fiber products, Kerui will conduct strict quality control to ensure these products meet the specifications and standards. After passing the quality control checks, Kerui employees will pack the these products for delivery. Additionally, packaging methods may vary depending on the product form and customer requirements. Then Kerui workers will ship these products to their intended destinations and ready for use in various applications. If you wonder more information about refractory ceramic products, you can have a look at what others say in Quora.

  • High-quality as well as fast production;
  • Safe and on-time delivery;
