Ceramic Injection Molding (CIM) is a branch of Modern Powder Injection Molding (PIM) technology. It is a precise ceramic plastic molding method, which is the fastest growing and application in the world. The most extensive precision manufacturing technology for ceramic components.
Ceramic injection molding is a new process for preparing ceramic parts by combining a polymer injection molding method with a ceramic preparation process.
Asia Billion is a custom injection mold and molding company , we are also the ceramic injection molding manufactures. one of our board directors know this subject very well as they graduated from the world famous Jingdezhen ceramic college in Jiangxi Province of China for ceramic industry. we put our R&D team in the college testing labs and have a strong cooperation with the college, it can let us to learn and use the latest technology and material to service our global customers.
Ceramic injection molding technology and process advantages:
1) Mass production can be carried out quickly and automatically, and the process can be precisely controlled;
2) The part density is uniform due to the flow filling;
3) Due to the high pressure injection, the powder content in the mixture is greatly increased, the shrinkage of the sintered product is reduced, the product size is precisely controlled, the tolerance is up to ±0.1% to 0.2%, and the mechanical performance is superior;
4) No need for machining or only a small amount of processing, reducing the cost of preparation;
5) can make the complex shapes, with transverse holes, inclined holes, concave and convex surfaces, threads, thin walls and difficult to machining part, it have wide application prospects.
Application of ceramic injection molding technology:
At present, ceramic injection molding technology has begun to develop towards precision. The focus of research and development has expanded from past high-temperature non-oxide ceramics (such as silicon nitride and silicon carbide) to oxide ceramics (such as zirconia, alumina) and functional ceramics. There are more and more types of bioceramic products, and their main application areas are as follows:
1) Ceramic parts for medical devices
Ceramic injection molding technology in the medical field has also been used more and more. The ceramic injection molding process is used to make a variety of medical instruments such as ceramic scalpels, which have the advantages that are not possessed by conventional metal instruments such as antibacterial, corrosion resistant, and not easily stained. Typical products mainly include: artificial bone, artificial joints, artificial gums, dental trays, medical knives, etc.
2) Precision ceramic parts for electronics
In the IT and electronics industries, the heat dissipation of components requires the use of a fan. The use of ceramic bearings in the fan can reduce noise and extend life, which is superior to metal bearings. ZrO2 and Si3N4 ceramics not only have good wear resistance, high fracture toughness, but also have certain self-lubricating properties, so they are ideal candidates for the manufacture of ceramic bearings. Typical products mainly include: optical fiber conduits, integrated circuit substrates, resistors, heating elements, etc.
3) Precision ceramic parts for optical communication
There are mainly zirconia polycrystalline ceramic ferrules and ceramic sleeves for fiber optic connectors. Because of its small size, high precision, and a bore diameter of only 125 microns, it can only be injection molded. At present, the ceramic ferrules and ceramic bushings required for fiber optic connectors are mainly manufactured in China, and the products produced by foreign companies such as Kyocera, Toto, and Adamand are decreasing.
3) Precision ceramic parts for the electromechanical industry
Including various alumina (Al2O3) system insulation ceramic parts, such as integrated circuit package tube; electric vacuum switch ceramic tube; microwave oven for insulating ceramics and insulating ceramic lamp holders.
4) Precision machinery and micro ceramic parts
With the development of the precision machinery and microelectronics industries, there is an increasing demand for small and micro-precision ceramic components, including ceramic injection molding (CIM) shaft and pinion planetary gear transmissions, ceramic screws and planetary gears, and micro-oxidation. Zirconium ceramic plain bearings have an outer diameter of only 1.5 mm.
5) Bio-ceramic products
It mainly includes artificial ceramic teeth, implant dental ceramic fixing screws, artificial joints, fixed crown sleeves, and ceramic brackets for orthodontics. According to the World Health Organization, the rate of dental malformation is about 49%. In 50-60% of households in the United States, orthodontics can be performed, and orthodontic brackets must be worn. The products produced by ceramic injection molding have high dimensional accuracy and good performance, and have broad market prospects in China.
As an emerging precision manufacturing technology, ceramic injection molding technology has its unique advantages. In particular, the continuous expansion of industrialization in the world in recent years has more fully proved the attractive development prospects of CIM technology. The combination of excellent physical and chemical properties of ceramic materials and precision injection molding will definitely make CIM technology play an increasingly important role in high-tech fields such as aerospace, defense, military and medical equipment, and become the most sophisticated ceramic parts at home and abroad. Advanced preparation technology with advantages.
