Alumina Ceramic Injection Molding


Ceramics injection molding technology is similar to the metal injection molding, they are all the main branch of powder injection molding technology,and developing on the basis of polymer injection molding technology. Ceramics injection molding is the fastest-growing in the world, as well as the most widely used in the ceramic parts precision manufacturing technology.

Its outstanding:

1.A high degree of mechanization and automation;

2. Forming various ceramic parts of complex shape, so that the sintered ceramic product without machining or less machining, thus reducing the cost of the expensive ceramic processing. Molding of ceramic products have high dimensional accuracy and surface finish. Ceramic injection molding technology has been made in high precision and high value-added new products on show with its unique advantages.

At present, alumina ceramic with its unique advantages are widely used in high-tech and cutting-edge industries such as microelectronics, nuclear reactions push MHD power generation, aerospace, artificial bone and artificial joints. Due to the high hardness of alumina ceramic, hard cutting, especially for aluminum articles of complex shape, such as automobile engine turbocharger rotor, bones, teeth and other biological ceramics, sintered after molding is finished, without further processing , while the traditional molding techniques (such as dry pressing, isostatic pressing, etc.) subsequent machining large, it is difficult to meet the demanding requirements.

Ceramic injection molding include the following four aspects: the ingredients and mixing, injection molding, debinding and sintering. The first three are peculiar to the ceramic injection molding process. Due to the small ceramic powders in ceramic injection molding and irregular shape, the process parameters compared to the control of metal injection molding is more delicate.
