How Are Ceramic Bottles Manufactured?

The process of making ceramics today looks very different from the clay ovens and kilns that tempered the first pots, though the core principles have remained. Industrial ceramics products have a high level of precision and are often made from moulds and castings. Injection molding, slip casting and dry pressing are just a few of the techniques used in advanced ceramics processing.

While each stage in the ceramic manufacturing process can look different depending on the desired shape and raw materials being used, in technical ceramics, the process follows a very similar pattern.

1. Injection Molding

Injection molding is a manufacturing process of advanced ceramics that functions similarly to the way plastics are made. The combined materials are heated into a molten substance and injected into a mould to produce the desired shape.

2. Milling

The raw materials are prepared for ceramics processing through a number of different techniques. This stage is designed to separate the raw materials from any impurities that may exist and to prepare them for better mixing and forming.

3. Sizing, Batching and Mixing

Through sizing, the raw materials are refined even further depending on the intended application. Batching in ceramic manufacturing is the mixing of different raw materials into predetermined compounds. The batched materials are then mixed to give the resulting product a more homogeneous and uniform composition.

4. Slip Casting

As a ceramic forming technique, slip casting is used for producing shapes that are difficult to form on a potter's wheel. A liquid clay mixture is poured into a plaster mould that allows the clay to form and harden. The shapes produced by slip casting are highly precise and consistent.

5. Forming

The raw materials have now been sized, batched and mixed into their desired amount. The ceramic materials are now formed into shape using any number of ceramic manufacturing processes. After some time, the clay mud is forming in the mold, thendemolding.

6. Glazing

After being formed and left to dry, the ceramic materials are then glazed. Each glaze has different properties that will help to determine the finish of the final product. In particular, dried powder pressing uses glazing techniques to support the physical properties of the pressed part.

7. BiscuitFiring

The firing process in ceramic manufacturing involves placingthe formed and glazedbottles into a sintering oven for heat treating 1200-1300℃.. The sintering process creates density and hardens the material into its final result.

8. Decal label

Labels of different design and color can be applied to the bottle, and then cook.

9.  Inspection and pack

Final inspection one by one then pack as customers’ requirement
