Production know-how
Pharmaceutical eye droppers: how we make them
- LDPE is temperature-sensitive: before blowing it shrinks easily and can leave weak bottoms, especially in the outer cavities – which is why eye droppers are usually made on small machines.
- Victor’s temperature control keeps every cavity of a multi-cavity mold even, so eye droppers can run on larger machines.

Three-station injection blow molding
One machine, three stations, a finished bottle
- Station 1 · 0°
Injection
The preform is injection molded on a core rod – the neck and thread of the pharmaceutical eye droppers are finished here and never change again.
- Station 2 · 120°
Blowing
The table turns 120° and air through the core rod blows the warm preform into the bottle mold. No parison, no pinch-off, no flash.
- Station 3 · 240°
Stripping
Another 120° and the finished bottle is stripped off the rod, ready to pack – no trimming and no scrap, with all three stations working at once.
