Dry pressing is one of the most widely used forming processes in advanced ceramics manufacturing. This method involves applying unidirectional or bidirectional pressure to granular powder within a mold, rapidly pressing it into a green body with a certain strength and shape.

Dry pressing is known for its high efficiency, low cost, and good dimensional consistency, making it particularly suitable for ceramic parts with relatively simple structures that require mass production.

Our Factory Advantages

Molding quality control and large-scale production capacity

GORGEOUS CERAMICS (GGS) boasts a mature dry pressing process, ensuring consistent density distribution across its products.

Our molding density fluctuations are controlled within ±1–2%, effectively reducing common issues such as delamination, cracking, and uneven strength.

We utilize automated pressing, with a single-piece molding cycle of only a few seconds, achieving an annual production capacity of 35 million pieces.

Ceramic dry pressing process flow

The common production process of ceramic dry pressing mainly includes the following key steps.

Raw material powder -> Powder pretreatment (grinding/sieving/impurity removal) -> Batching and mixing (adding binders and lubricants) -> Granulation (spray granulation/dry granulation) -> Powder aging (stability and flowability) -> Automatic material feeding (filling the mold) -> Dry pressing (unidirectional pressing/bidirectional pressing) -> Demolding (obtaining green body) -> Green body trimming -> Degreasing (removing organic matter) -> High-temperature sintering (densification) -> Precision machining (grinding/drilling/CNC) -> Inspection and quality control (dimensions/density/performance) -> Finished product warehousing/shipment
