Eye dropper outer cap mould
A dropper closure is an assembly: the outer cap that screws onto the neck, the pipette that reaches into the bottle, and the bulb that draws the dose. We tool the injection-moulded parts and cut them to the neck and to the bulb you already buy.

What is on the drawing
The drawing on this page is a dropper closure in section: the outer cap with its knurl, the thread that pulls it down onto the neck, and the profile of the pipette below it. The parts are dimensioned against each other so the pipette ends where the bottle needs it to, and so the cap still closes once the bulb is fitted.
See every cap mould we cut, from flip tops and two colour caps to tear-off closures.
The bulb itself is a rubber or silicone part and comes from your own supplier; send the one you use and the cap is cut to it. Dropper closures are usually bought together with the bottle they go on, and AMAN cuts small pharmaceutical and cosmetic bottle tooling in the same workshop, so a dropper programme is quoted as one job. North American buyers search for the same thing as a dropper cap mold.

Seven questions about the tool itself
The seven that decide whether you order, answered for this tooling. Where a figure is on the drawing we print it; where it depends on your part we say which numbers we will ask you for.
Hot runner or cold runner?
A dropper closure is a set of small light parts, so a low cavitation tool is normally cold runner and a high cavitation one hot. The decision is made per part and printed in the quotation.
Cycle time and output
Small parts run fast, and the limit is usually how quickly they can be taken out, not how quickly they cool. Tell us the sets per hour and the cavitation is worked back from it.
How the part is ejected
Outer caps are stripped off the core; the pipette and the bulb ring have their own arrangements. The full layout is approved with the drawing before cutting.
Tryout report and acceptance
The tools are run here and the moulded parts ship with them. Whether the assembled dropper seals on your bottle is the acceptance point that matters; send the bottle and it is checked here.
Spare parts
Cavities, cores and stripper rings are cut from the same drawings. Tell us which spares to pack.
Warranty
Warranty terms are written into the quotation for the set of tools.
Will it fit your machine?
Tell us the make, model and tonnage. Small part tools often run on a smaller machine than the rest of your shop, so name the one this set will run on.
What we will ask you for: the bottle neck, the pipette length, the part weights, the sets per hour, and the machine.
How many small parts an hour do you need?
Dropper parts are small, so this is the number that decides whether the tool is cut at eight cavities or at sixteen. Small parts at high cavitation are routine work here.
