Plastic syringes are mass-produced through extrusion and injection moulding
The plastic syringes themselves are constructed from various plastics, including polypropylene, polyethylene, polycarbonate, and polyethylene terephthalate. These materials are chosen based on the specific application and processing techniques required. For example, polypropylene syringes are commonly used in adhesive dispensing due to their excellent chemical resistance, while polycarbonate syringes are preferred when transparency and visibility of the adhesive are necessary.
The extrusion moulding process involves feeding plastic granules or powder into a large hopper. A large spiral screw forces the material through a heated chamber, creating a thick, flowing mass. This mass is then pushed through a die, forming a continuous tube that is cooled and cut. This method is suitable for producing the syringe tube, which can be made of plastic or glass.
Injection moulding is used for more complex shapes like the ends, the plunger, and the safety caps. This process involves heating the plastic to liquify it and then forcibly injecting it into a mould that is the inverse of the desired shape. Once the plastic cools and solidifies, it maintains its shape. The plunger head, typically made of rubber, can also be manufactured through injection moulding.
Plastic syringes are mass-produced due to their affordability and disposability, reducing the risk of spreading blood-borne diseases. They are commonly used in medical settings, such as administering injections, infusing intravenous therapy, and drawing or measuring liquids.

They are made from plastics like polypropylene, polyethylene, and polycarbonate
Plastic syringes are commonly made from polypropylene, polyethylene, and polycarbonate. The type of plastic used depends on the specific application and processing techniques, such as the method of sterilisation or decontamination. Polypropylene syringes, for instance, are widely used in adhesive dispensing due to their excellent chemical resistance. They can handle adhesives with corrosive materials or solvents. Polypropylene is also used in laboratory-grade syringes, which are chemically resistant and do not have rubber tips.
Polyethylene syringes are also used for adhesive dispensing, particularly for less aggressive adhesives. This type of plastic is known for its flexibility and compatibility with various adhesives. Polyethylene terephthalate (PET) syringes are another option, offering good chemical resistance and the ability to handle different adhesives. They are available in various sizes and shapes to meet specific industry needs.
Polycarbonate syringes are a popular choice when transparency and visibility of the adhesive are required. They are known for their high clarity, allowing operators to monitor the adhesive flow accurately. This precision is essential in certain adhesive dispensing processes.
The selection of plastic materials for syringes is critical in ensuring the quality and efficiency of manufacturing processes. It is important to consider factors such as chemical compatibility, durability, and precision to meet the demands of adhesive dispensing in non-medical contexts.

Plastic syringes are cheap, disposable, and reduce the risk of blood-borne diseases
Plastic syringes are mass-produced because they are cheap to produce, disposable, and reduce the risk of blood-borne diseases. They are made from certain grades of polypropylene (homo-polymer and/or co-polymer polypropylene), cyclo-olefin copolymer, and cyclo-olefin polymer. The plunger and seal are usually made from rubber.
Plastic syringes can be constructed as either two-part or three-part designs. A three-part syringe contains a plastic plunger/piston with a rubber tip to create a seal between the piston and the barrel. Two-part syringes, on the other hand, are manufactured to create a perfect fit between the plastic plunger and the barrel, eliminating the need for a separate synthetic rubber piston. Two-part syringes have traditionally been used in European countries to prevent the introduction of additional materials such as silicone oil, which is necessary for lubricating three-part plungers.
Plastic syringes are cheap to produce because the material used for the barrel should be chosen based on the intended application and processing techniques, such as the sterilization or decontamination method. The material should also exhibit appropriate performance properties, such as oxygen and water permeability. This flexibility in the choice of materials allows manufacturers to select cheaper options while still adhering to the minimum requirements.
Plastic syringes are disposable, which is crucial for reducing the risk of spreading blood-borne diseases. Reusing needles and syringes has led to the spread of diseases, especially HIV and hepatitis, among intravenous drug users. Plastic syringes can be safely disposed of in sharps containers, which are designed to collect small, sharp objects and contaminated items to limit exposure to nearby workers.
Additionally, plastic syringes are often pre-filled with liquid and marketed as disposable syringes. These pre-filled syringes are constructed with materials that are suitable for the sterilization method and specific requirements as primary packaging for injectable drug products. The materials used should not physically or chemically affect the syringes during normal use and should be safe for their intended purpose.

They are ISO-compliant and must meet FDA specifications
Plastic syringes are mass-produced as they are cheap enough to be disposed of after being used only once, reducing the risk of spreading blood-borne diseases. They are also commonly reused by diabetics who require multiple daily insulin injections.
To ensure the safety and efficacy of these medical devices, plastic syringes must adhere to specific standards and regulations. They are ISO-compliant and must meet FDA specifications. The International Organization for Standardization (ISO) sets forth a range of requirements and guidelines that plastic syringes need to meet. These standards encompass various aspects, such as the materials used, performance characteristics, and safety considerations.
For instance, the ISO 11040 series provides guidelines for prefilled syringes, including ISO 11040-6, which specifically addresses plastic barrels for injectables. It dictates that suitable polymers should be selected based on the intended application and processing techniques, including sterilization methods. Additionally, the ISO 8871 series outlines requirements for plunger stoppers, ensuring they maintain their performance throughout the shelf life of the medicinal product.
Compliance with FDA specifications is also crucial for plastic syringes. The U.S. Food and Drug Administration (FDA) provides guidance and regulations to ensure the safety and effectiveness of medical devices, including piston syringes. This includes requirements for premarket notification, compatibility and stability data, reuse durability, and biological specifications.
By adhering to ISO standards and FDA specifications, plastic syringe manufacturers can ensure the quality and safety of their products, protecting patients and end-users from potential harm. These regulations help maintain consistency and control in the production and performance of plastic syringes, contributing to the overall reliability of these medical devices.
