Ceramic Extruder Screw

Product Introduction:

Ceramic molding method refers to the process of making ceramic products of desired shape and size through a series of processing of ceramic raw materials. The methods include manual molding, die molding, injection molding, extrusion molding, pressing molding, grouting molding, injection molding, printing molding and so on.

Among them, injection molding is the method of heating the ceramic raw materials to the semi-fluid state, and injecting the raw materials into the mold by the injection molding machine. This method can produce ceramic products with complex shapes, such as ceramic electronic components and ceramic ornaments.

Extrusion molding is the method of heating ceramic raw materials to a semi-fluid state, extruding the raw materials into the required shape by the extruder, and then forming by oxidation sintering and other processes. This method is suitable for the production of large-scale ceramic pipes, ceramic bars and so on.

Injection molding is the method of injecting ceramic raw materials into the injection machine, and injecting raw materials into the mold through high pressure injection. This method is suitable for the production of high precision, high quality ceramic products, such as ceramic chips, ceramic titanium oxide and so on.

Ceramic extruder screw is the core part of the extruder, which determines the performance and production efficiency of the extruder. The screw of ceramic extruder processes raw materials into ceramic products with a certain shape and density through the continuous operation of feeding, compression and metering in three stages. The material enters through the feed port and is pushed forward through a spiral shaped path. In the process of propulsion, the raw material is compressed and frictioned, and is initially compressed and homogenized. In the compression section, the spiral shape of the screw gradually becomes shallow, and the shear force and extrusion pressure of the raw material gradually increase, and the temperature gradually rises. In this process, the raw materials are further compressed and homogenized, while thermal decomposition and recrystallization occur, forming ceramic products with a certain shape and density. In the metering section, the shape of the screw changes again so that the material is subjected to final compression and homogenization as it is pushed forward. At the same time, the metering section also fine-tuned the shape and size of the extruded product to make it meet the production requirements.

Jed screw through the optimization design and adjustment of ceramic extruder screw, can improve the production efficiency and product quality of extruder. Welcome new and old customers to inquire and order, the order hotline: +8613567672668， WhatsAPP/WeChat with the same number.
