Ceramic injection molding technology began to develop to precision, the focus of research and development from the past high temperature non-oxide ceramics (such as silicon nitride, silicon carbide) expanded to oxide ceramics (such as zirconia, alumina), functional ceramics, bioceramics products, more and more types, its main application fields are as follows.
Precision ceramic components for optical communication
There are mainly zirconia polycrystalline ceramic inserts and ceramic sleeves for fiber connectors. Due to its small size, high precision and inner hole diameter of only 125 microns, injection molding can only be used. At present, the ceramic core and ceramic bushing for optical fiber connectors are mainly made in China.
Bioceramic products
It mainly includes artificial ceramic teeth, ceramic fixation screw for implant teeth, artificial joint, fixed crown cover, ceramic bracket for orthodontic teeth, etc. According to the statistics of the World Health Organization, the incidence of dental deformity is about 49%. In the United States, 50-60% of families will have orthodontics, which must be equipped with orthopaedic brackets. This kind of product produced by ceramic injection molding has high dimensional precision and good performance, and has a broad market prospect in China.
Ceramics for cultural life
Ceramic powder injection molding has been successfully used in the preparation of ceramic watch case, watch chain, such as Chanel international brand ceramic watch and Swiss “radar” never wear high-grade watch case and watch chain. In recent years, the shell and buttons of high-end mobile phones are also made of ceramic injection molding. Wear-resistant ZrO2 ceramic materials are used, and the surface roughness after polishing is controlled at about 30 nm.
Precision ceramic components for electronics
In the IT and electronic industries, fans are needed for heat dissipation of components. If ceramic bearings are used in the motor of the fans, noise can be reduced and life can be extended, which has greater advantages than metal bearings. ZrO2 and Si3N4 ceramics not only have good wear resistance, high fracture toughness, but also have a certain degree of self-lubrication, so they are ideal candidates for manufacturing ceramic bearings.
Precision ceramic components for electromechanical industry
Including various alumina (Al2O3) system insulating ceramic parts, such as integrated circuit packaging shell; Electric vacuum switch ceramic tube; Insulating ceramic for magnetron in microwave oven; British Morgan company production of direct drive motor ceramic parts, as well as disk drive parts.
Transparent alumina ceramic products
A number of transparent alumina ceramic products have been prepared using injection molding techniques, including transparent ceramic brackets for orthodontics, transparent ceramic arc light tubes in ceramic metal halide bulbs, and translucent alumina ceramic cups that are both functional and aesthetic
Precision machinery and micro ceramic components
With the development of the precision machinery and microelectronics industry, the demand for small and micro precision ceramic components is increasing, including ceramic injection molding (CIM) prepared shaft and pinion planetary gear transmission, ceramic screw and planetary gear, and micro zirconia ceramic plain bearings with an external diameter of only 1.5 mm
Ceramic parts for medical instruments
At present, ceramic injection molding technology has been more and more applied in the medical field. The ceramic injection molding process is used to make a variety of medical instruments such as ceramic scalpel, which has the advantages of antibacterial, corrosion resistance and not easy to be stained.
Wear-resistant ceramic parts for textile machinery
At present, a large number of wear-resistant ceramic parts are used in the textile industry, mainly yarn guide wheel, drawing wheel and other products, most of which use alumina (Al2O3) with high hardness and zirconia (ZrO2) with good toughness and wear resistance, as well as silicon nitride and silicon carbide ceramic materials. These products have complex shape and high dimensional precision, so the ceramic precision injection molding technology is widely used. Wear-resistant parts of textile ceramics produced by German Seruntec are widely used
Environmental protection, chemical, metallurgical ceramic nozzle
The shape of the nozzle is complex, with small holes, and requires wear resistance, corrosion resistance and high temperature resistance. Zirconia (ZrO2) and silicon carbide (SiC) silicon nitride (Si3N4) powder can be used for one-time injection molding to prepare ceramic nozzles of various shapes with excellent performance
