Laundry detergent cap mould
A laundry closure is two parts and one job: the inner cap that seals the bottle, and the overcap the buyer pours the dose into and screws back on wet. Both are cut here, to the same neck, so the set goes back on straight every time.

What is on the drawings
The overcap drawn on this page is moulded in HDPE at Ø59.8 mm and 65.65 mm high, at 15.4 ± 1 g, in an eight cavity tool. Those four numbers come off our own drawing for that closure, not from a catalogue: the weight is what the customer sells at and the cavity count is what their output needed.
See every cap mould we cut, from flip tops and two colour caps to tear-off closures.
The second set on this page is an upper and a lower laundry cap drawn as a pair. A detergent closure that doses has to survive being put back on with wet hands, so the thread lead and the seal face are cut to the neck the bottle really has. North American buyers write detergent cap mold for the same set.

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?
The overcap and the inner cap are decided separately. A large dosing overcap is heavy, so the gate position and the runner type are set by its weight and cavity count; the quotation says which one each tool uses.
Cycle time and output
Both parts have to reach the filling line together, so the two cavity counts are balanced against each other. Tell us the closures per hour and both are worked back from it.
How the part is ejected
A dosing overcap is stripped off the core; a deep skirt needs the stripping force and the air valve checked before the steel is cut. The layout goes to you with the mould drawing.
Tryout report and acceptance
Both tools are run here and the moulded caps ship in the crate. Whether the wet cap still screws back on straight is the acceptance point customers name most often on this closure.
Spare parts
Cavities, cores and stripper rings for both tools are cut from the same drawings. Tell us which sets to pack.
Warranty
Warranty terms are written into the quotation for the pair of tools.
Will it fit your machine?
Tell us the make, model and tonnage for each tool. A large overcap often needs a bigger machine than the inner cap does, so say what you have for both.
What we will ask you for: the bottle neck, the dose the overcap has to hold, both part weights, the closures per hour, and both machines.
How many closures an hour do you need?
An overcap and an inner cap have to arrive at the filling line together, so the output sets two cavity counts at once. Tell us the number you are planning around.
