Effervescent tablet tube mould manufacturer
An effervescent tube is a moisture barrier with a lid. If the ring where the cap meets the tube is a fraction loose, the tablets are soft by the time they reach the shop. That ring is cut on two tools at the same time.

The numbers on this programme
The tube body is Ø31.3 × 145 mm in PP; the cap is Ø35 × 20 mm in LDPE. Both tools are 16 cavities with a hot runner and 16 valve gates, both were built for a 280 T injection machine, and the process record for the tube gives a cycle of about 18 seconds.
Those figures are off our own drawings and process record for that job. They will move on your part, because a different wall or a different tablet count changes the cooling, and the real number for your tube is calculated with the quotation rather than copied from this page.
The moisture seal is the whole point of the job. The cap and the tube were drawn against each other, so the sealing ring exists on one set of drawings; the cap is ejected by a slide and a stripper plate, which is what a big thin lid needs if it is not going to be marked. North American buyers write effervescent tablet tube 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?
Hot runner on both tools of this programme: 16 valve gates on the tube and 16 on the cap. With 16 cavities and a thin wall that is what keeps every cavity filling the same way; a smaller tube programme may well be quoted cold.
Cycle time and output
The process record for the tube on this programme gives about 18 seconds. That figure belongs to that tube on that machine: change the wall, the tablet count or the machine and it changes, so the number for your tube is calculated into the quotation rather than promised from this page.
How the part is ejected
The cap on this programme comes off on a slide with a stripper plate, which is how a wide thin lid is released without marking it. The tube body ejection is drawn to your wall and sent with the mould drawing for approval.
Tryout report and acceptance
Both tools are run here and the moulded tubes and caps ship with them. On this job the acceptance point is the seal: how the cap seats on the tube and whether it holds after it has been opened and closed.
Spare parts
Cavities, cores, the valve gate tips and the stripper rings are cut from the same drawings on the same machines. Valve gate tips are a usual spare on a hot runner tool; say how many sets to pack.
Warranty
Warranty terms are written into the quotation for the pair of tools.
Will it fit your machine?
Both tools on this programme were built around a 280 T machine. Tell us the make, model and tonnage of yours and the platen, tie bars and ejector layout are checked against it before anything is cut.
What we will ask you for: the tube diameter and length, the wall, how many tablets per tube, the materials, the tubes per hour, and the machine you will run them on.
How many tubes an hour do you need?
Cavity count follows the output, and the cavity count is most of the price of a tool like this one. Tell us the number you are planning around and both tools are quoted to it.
