Ceramic dielectric filter manufacturing process
The invention discloses a ceramic dielectric filter manufacturing process. The manufacturing process comprises the following steps: step 1, weighing of raw materials: weighing ceramic powder and a ceramic forming agent with corresponding weights according to the mass percentages of 75wt%-90wt% and 10wt%-25wt% respectively; step 2, mixing and granulation: mixing the ceramic forming agent and ceramic powder for 20 min-30 min in a mixer, evenly mixing the raw materials, then placing in an internal mixer with the preheating temperature of 145 DEG C-160 DEG C to be preheated and melted, wherein thepreheating temperature of the internal mixer after preheating and melting is 150 DEG C-165 DEG C, the temperature during kneading and mixing is 170 DEG C-200 DEG C, kneading for 25 min-110 min at thetemperature of 175 DEG C-210 DEG C, and then carrying out granulation; and step 3, injection molding: loading the ceramic feedstock into an injection molding machine, and carrying out injection molding at an injection temperature of 130-210 DEG C and a mold temperature of 35-140 DEG C. According to the invention, the density of the produced ceramic dielectric filter is more uniform, and the yieldof defective products is effectively reduced.
本发明公开了一种陶瓷介质滤波器制造工艺，步骤一：称取原料：按照质量百分比分别为75wt％～90wt％和10wt％～25wt％称取对应重量的陶瓷粉料与陶瓷成型剂；步骤二：混料造粒：将陶瓷成型剂与陶瓷粉料使用混料机内混合20min～30min，将原料混合均匀后置于预热温度为145～160℃的密炼机中预热熔融，预热熔融后密炼机预热的温度为150～165℃，揉炼混合时的温度为170℃～200℃，在175℃～210℃的温度下揉炼25min～110min后造粒，得到陶瓷喂料；步骤三：注射成型：将上述陶瓷喂料装于注射成型机中，在注射温度为130℃～210℃，模具温度为35℃～140℃；本发明能够让生产出的陶瓷介质滤波器密度更加均匀，有效降低了残次品的出产率。
