Disposable Plastic Syringe Manufacturing

syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel.[2] The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the front (open) end of the tube. The open end of the syringe may be fitted with a hypodermic needle, a nozzle or tubing to direct the flow into and out of the barrel. (From wikipedia)

Most parts of disposable plastic syringe are manufactured by injection molding, such as barrel, plunger, hub and cap.

Raw material for disposable plastic syringe

The raw material of disposable syringes is usually polyethylene (PP), which is usually medical grade and has relevant certifications. But as far as I know, not all hospitals strictly use syringes made of medical grade PP raw materials. On the other hand, the syringe manufacturer will also determine the quality of the material according to the scale and grade of the hospital. 

The quality PP material should have the following features:

(1) Various sterilization options (high pressure, hot steam, ethylene oxide, gamma ray, electron beam).

(2) Excellent transparency and gloss.

(3) Excellent balance of rigidity and impact resistance, basically no distortion.

(4) Good low temperature and impact resistance.
