Aiming at existing problems of injection molding of microfluidic chip, such as filling difficulty and low molding accuracy of microchannel, the method of ultrasonic vibration assisted injection molding of microfluidic chip was studied, and an ultrasonic vibration assisted injection mold for microfluidic chip was designed. The ultrasonic vibration system and injection mold were integrated effectively by introducing hot runner system innovatively. The unique disposal of runner system and cavity enabled the molding of substrate and coverslip simultaneously in a single mold. The nondestructive demoulding of microfluidic chip was achieved by using an improved secondary demoulding device.
