For the sector ophthalmic HPT developed a dropper-closure system which is completely manufactured under clean room conditions. The injection moulding tool for the dropper is a modular design so that different sizes of openings can be reproduced by exchanging individual parts or components. In the standard a large range of output quantities (dropper sizes) are possible depending on the customer’s requirements.
The screw cap itself was equipped with a tamper-evident closure. Due to an intelligent tool design also here it is possible to produce the same closure without tamper-evident band only by exchanging some parts in the tool. Also for the sealing system itself we moved in a new direction. In the ophthalmic sector it is of utmost importance that the output quantity remains constant over the period of application. This requirement was given particular attention to during the development.
Due to the variable structure of the tools we are as a result very well positioned to respond to specific customer demands. These possibilities offer a significant saving in tool costs as by exchanging only some tool parts or components different opening diameters can be made without having to manufacture a completely new tool, which in turn represents a benefit for our customers.
