Disposable special syringe for pharmaceuticals to treat bladder dysfunction or rather 3-part disposable syringe with Luer lock made of the high-performance plastic COC Topas
GPE designed the syringe components according to the applicable standard specifications and engineered the corresponding injection moulds and the associated automation. This encompasses, among other processes, the handling technology, siliconisation of the syringe barrel, laser marking and packaging.
GPE achieved the necessary sliding forces and breakaway torque pursuant to the standard specifications through the systematic use of a siliconised barrel interior and harmonising the tight fit between the syringe barrel and plunger stopper (the ‘stick-slip phenomenon’).
To spare the customer the effort of affixing a band with adhesive, a change in colour is realised by means of laser marking. The laser batch printing machine used for this purpose was adapted to GPE’s processes and equipment. Adding the scale by laser allows the syringe bodies to be marked with a logo selected by the customer and a QR code containing all of the relevant product information including the batch number.
The entire manufacturing process is carried out under class 7 clean room conditions according to DIN EN ISO 14644-1, from the injection moulding process in an enclosure with a laminar flow cabinet to automation, lasering and siliconisation (each with ventilation) as well as packaging.
