Introduction

Disposable syringes are essential medical devices used globally to administer vaccines, medications, and in various diagnostic procedures. The manufacturing process involves several critical stages to ensure safety, effectiveness, and compliance with international standards.

Manufacturing Process

Raw Material Selection

The primary materials used for disposable syringes include polypropylene and stainless steel. The choice of material impacts the syringe's durability and compatibility with different medications. Polypropylene is chosen for its clarity, strength, and resistance to chemicals.

Injection Molding

Injection molding is utilized to produce the barrel and plunger of the syringe. The process involves heating polypropylene to a temperature between 200°C and 250°C, which is then injected into molds under high pressure of 10,000 psi to 20,000 psi. The cooling time ranges from 10 to 15 seconds, depending on the mold design.

Assembly

Once molded, the components are assembled. The plunger is inserted into the barrel, and the needle, made from stainless steel, is attached. Automation is employed to enhance precision, with assembly lines running at speeds of up to 500 units per minute.

Sterilization

Sterilization is achieved through ethylene oxide treatment or gamma radiation. Ethylene oxide sterilization requires maintaining temperature between 50°C to 60°C for 8 to 12 hours. Gamma radiation, on the other hand, involves exposure to cobalt-60 with doses ranging from 25 kGy to 50 kGy.
