Ultrasonic Coating of Silicone Oil on Syringes

Ultrasonic Spraying Machine Coating Silicone Oil on the Inner Wall of the Syringe Process

In the production of medical syringes, ultrasonic spraying machines are the core equipment for achieving precise coating of silicone oil on the inner wall, which can effectively improve the performance and safety of syringe use. This process uses medical grade silicone oil as the coating material and relies on the principle of high-frequency ultrasonic vibration to solve the pain points of poor uniformity and material waste in traditional coating methods, adapting to the strict standards of medical consumables.

The core process of the technology is clear and efficient: first, the medical silicone oil is proportioned and uniformly delivered to the ultrasonic nozzle through a precision metering pump; The nozzle utilizes a high-frequency vibration of 20-120kHz to atomize silicone oil into uniform droplets of 5-50 μ m. Combined with a probe type nozzle design, it can achieve 360 ° no dead angle spraying deep into the inner wall of the injector. Meanwhile, through a multi axis linkage control system, the spraying speed, flow rate, and droplet size are precisely adjusted to ensure uniform and controllable coating thickness.

This process has significant advantages: non-contact spraying avoids secondary pollution of the inner wall of the syringe, with a material utilization rate of over 95%, significantly reducing waste of silicone oil; Room temperature coating does not require high temperature heating, protecting the syringe substrate from damage; The coating has strong adhesion, no particle shedding, meets ISO 10993 biosafety requirements, and is suitable for common medical sterilization methods such as ethylene oxide.

The coated silicone oil coating can significantly reduce the frictional resistance between the plunger and the inner wall of the syringe, making it easier and more precise for medical staff to operate, reducing patient discomfort during injection, and avoiding drug residue to ensure medication accuracy. At present, this process has been widely used in the large-scale production of disposable syringes, providing reliable guarantees for medical diagnosis and treatment safety.
