Alumina ceramics have high hardness, high strength, insulation, wear resistance and corrosion resistance. They are widely used in machinery manufacturing, aerospace, petrochemical and other fields. Next, Pintejin Ceramics will introduce the characteristics of alumina ceramic injection molding. .
Features of Alumina Ceramic Injection Molding
- 1. The alumina ceramic molding body has high strength and can be machined into parts with complex shapes. Due to the action of organic polymers, the strength of the body is 20-40MPan. The parts with this strength can be processed in various ways.As a result, parts with more complex shapes, more accurate dimensions and smoother surfaces can be processed, so the process reduces the production cost of the parts.
- 2. The overall uniformity of the alumina ceramic body is good, which can reduce the sintering temperature and greatly improve the reliability of ceramic parts. Because the composition and volume of the liquid-solid conversion before and after the molding process are unchanged, and the particles are solidified in situ.Therefore, as long as the molding process is completely filled, all parts of the molding blank have the same density, which can form large-volume parts, ensure the uniformity of the final parts, and improve the reliability of engineering ceramics.
- 3. Compared with the injection molding process of alumina ceramic injection molding, the content of organic matter is less and there is no difficulty in plastic removal. The organic matter in the slurry generally only accounts for 10% -20% of the liquid medium, which is equivalent to the weight of the ceramic dry material. 3% to 5%.Therefore, the plastic removal process is relatively easy and can be completed simultaneously with the sintering process, avoiding the time-consuming and energy-consuming plastic removal process of the injection molding process, saving energy and reducing costs.
- 4. Alumina ceramics can be formed near net size. Since the volume of the slurry becomes very small during the liquid-solid conversion process, the size of the green body after curing basically depends on the model.
In addition, due to the high solid content of the slurry, the formed green body has high density, small drying shrinkage and firing shrinkage, and small deformation, and can be formed near net size.
