所述供液槽1和气瓶2分别安装在密封成型室10上。The liquid supply tank 1 and the gas cylinder 2 are respectively mounted on the seal molding chamber 10.
密封成型室10为化学反应沉积过程提供环境，避免环境的干扰。The hermetic forming chamber 10 provides an environment for the chemical reaction deposition process to avoid environmental interference.
预先贮存于供液槽1的基体溶液4通过电磁阀门6由导管13通过喷液嘴14流入成型槽17中，成型前基体溶液4预先注满成型槽17，在成型过程中随着化学反应的进行，成型槽17中的基体溶液4会逐渐减少，则打开电磁阀门6使得预先储存的基体溶液4流入成型槽内进行补充。The base solution 4 previously stored in the liquid supply tank 1 flows through the electromagnetic valve 6 through the liquid discharge nozzle 14 into the molding tank 17, and the base solution 4 is pre-filled with the molding tank 17 before molding, and the chemical reaction is carried out during the molding process.
