Manufacturing luer-lock from plastic instead of glass

Manufacturing luer-lock from plastic instead of glass

News 25.09.2023

Even a good 150 years after their invention, the standardized luer connection systems for infusions and injections are still frequently made of glass. At Fakuma 2023, ZAHORANSKY will be exhibiting the associated Z.SONIC 16 luer-lock syringe injection mold from the PRIMA Z syringe production system, which can be used to manufacture luer-locks from plastic instead of glass. The advantages of the plastic versions are clear: plastic products are significantly more robust and easier to clean, both in handling and storage, compared to their glass counterparts. In addition, syringes made of plastic impress with their pH-neutral surface, a significantly lower heavy metal content, and greater freedom in product design. This results in increased shelf life for highly sensitive medications.

Safe and cost-effective manufacturing
The PRIMA Z production line makes it possible to produce plastic syringes with screw threads - the so-called Luer-Lock - extremely cost-efficiently and safely. Disposable needles, for example, can be screwed on easily afterwards and do not have to be injected during production. Syringes with volumes between 0.5 and 10 ml can be produced as standard, but special sizes of up to 50 ml are also possible. The material can also be varied: ZAHORANSKY injection molds easily process various technical polymers such as COC or COP. Based on customer-specific product designs, a cycle time of 15 to 17 seconds can be achieved on the production lines using the no-human-touch process. In the 16-cavity injection mold version, the Z.SONIC mold is thus capable of producing up to 3,840 parts per hour.
