Disposable Syringe Production Line

Five Steps of the Complete Syringe Production Process

1. Injection Molding
The syringe barrel and plunger are formed by high-precision molds installed on the injection molding machine. Hot-melt PP material is injected into the molds. This is the most critical step, as the mold design and accuracy directly determine the final quality of the syringe.

2. Barrel Printing
Scale lines and logos are printed on the syringe barrel. Clear, durable printing improves both usability and the overall appearance of the syringe.

3. Assembly
All components—barrel, plunger, gasket, and needle—are assembled into a complete syringe. A stable, high-speed assembly machine significantly increases daily production capacity.

4. Packing
Because syringes must remain clean before leaving the clean room, each set requires individual packing. This is done by an automatic blister packing machine or ribbon packing machine, depending on market preference. After individual packing, the syringes are placed into boxes and cartons.

5. Sterilization
To ensure sterility and safety, packed syringes undergo ethylene oxide (ETO) sterilization before entering the market. Optional systems such as preheating units can shorten the sterilization cycle, and residual gas treatment systems can help meet higher environmental standards.
