Disc top cap mould
A disc top is two moulded parts that have to click together and stay shut in a carton: the lower part that screws onto the neck, and the disc lid that flips open under a thumb. Both are cut here, against each other, so the click is designed rather than discovered at assembly.

What is on the drawing
The set drawn here is a 24 mm disc top: an upper disc lid and a lower part that screws on to the neck. Both halves are drawn together, which is the only way the hinge travel, the snap and the seal line can be held to each other.
See every cap mould we cut, from flip tops and two colour caps to tear-off closures.
A second disc top of ours is drawn as two separate tools, an upper and a lower, for a customer who wanted them quoted and delivered one at a time. Either way the two parts come off drawings that were made against each other; cavity count is quoted to the output you need. North American buyers write disc top cap mold for the same closure tooling.

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 disc top is two parts, the disc and its base, and each is decided on its own weight and cavity count. Small runs are cold runner; higher cavitation usually goes hot. Both choices are stated in the quotation.
Cycle time and output
The two parts have to arrive at the assembly line together, so the cycles are balanced against each other. Tell us the closures per hour and the two cavity counts are worked back from that.
How the part is ejected
The base is normally stripped; the disc has a snap feature that decides whether it is stripped or comes off a slide. The layout is drawn and approved before cutting.
Tryout report and acceptance
Both tools are run here and the moulded discs and bases ship with them. Snap force and the click of the disc are the acceptance points customers usually name; tell us yours.
Spare parts
Cavities, cores and the snap inserts are cut from the same drawings. Say which spares to pack.
Warranty
Warranty terms are in the quotation for the pair of tools.
Will it fit your machine?
Tell us the make, model and tonnage of the machine each tool will run on. They are often different machines, so say if that is the case.
What we will ask you for: the neck, the disc diameter, both part weights, the closures per hour, and the machines.
How many closures an hour do you need?
A disc top is two parts, so the output has to be hit by two tools that come off the line together. Tell us the number you are planning around.
