Injection molding method of microwave dielectric ceramic filter and ceramic filter thereof
The invention discloses an injection molding method of a microwave dielectric ceramic filter. The injection molding method comprises the following steps of: step 1, internally mixing and granulating 100 parts by weight of TMCCS powder and 10-30 parts by weight of an organic binder to obtain an injection molding material, wherein the TMCCS powder is formed by mixing TiO2, Mg (OH)2, CaCo3, CaTiO3 and SiO2 in a specific weight percentage; 2, carrying out injection molding on the injection molding material to obtain a green body; 3, carrying out thermal degreasing treatment on the green body; and4, sintering the thermally degreased green body at a high temperature to obtain a ceramic filter main body. According to the invention, the TiO2, Mg (OH)2, CaCo3, CaTiO3 and SiO2 are used as main materials; blending and internal mixing are performed on the main body materials and an organic binder, so that the comprehensive performance of the obtained injection molding material is more stable, theshrinkage error of the injection molding material is within 0.2%, the density of the green body is 3 +/-0.1 g/cm <3>, the density of a sintered product is greater than or equal to 5.0 g/cm <3>; and aself-designed high-precision runner mold is adopted, so that the size parameters of the degreased and sintered product can be free from processing, and therefore, production efficiency and productionquality are improved, and production cost is reduced.
本发明公开一种微波介质陶瓷滤波器注塑成型方法，包括以下步骤：步骤一：将重量份为100的TMCCS粉体和重量份为10‑30的有机粘结剂通过密炼、造粒后获得注塑料；其中，TMCCS粉体由特定重量百分比的TiO、Mg(OH)、CaCo、CaTiO、SiO混合形成；步骤二：将注塑料通过注塑成型得到坯体；步骤三：对坯体进行热脱脂处理；步骤四：对热脱脂后的坯体经过高温烧结得到陶瓷滤波器主体。本发明通过采用TiO、Mg(OH)、CaCo、CaTiO、SiO作为主体材料，并将主体材料与有机粘结剂进行混料密炼，得到注塑料综合性能更稳定，收缩率误差在0.2％以内，生坯密度在3±0.1g/cm，烧结后产品密度≥5.0g/cm，结合自行设计的高精密流道模具可以做到产品脱脂烧结后尺寸参数免加工，提高生产效率和生产质量，降低生产成本。
