Closure drawing
Outside diameter, height, thread, seal and the tamper band if there is one.
Closure tooling · Taizhou
Bottle cap and closure mold manufacturer.
OSLON builds cap molds from the closure you need to run, in the same Huangyan workshop as the PET preform molds. The drawing sets the tool. A cavity count from another project does not.
Published photographs
Two cap molds on record as pictures.
Cavity count is visible in the tooling. Resin, cycle, steel and the closure standard are not printed on these photographs, so they are not listed here.
What the project needs
The closure, the neck, then the mold.
Neck finish
The cap has to match the preform neck. A change from PCO 1810 to PCO 1881 is a different closure and a different preform.
Resin and function
Material, colour, seal, opening torque and whether the product is still, carbonated or hot-filled.
Machine and cavities
Target output and the press decide the cavity plan. 24 and 32 are photographs, not a menu.
Gate position
Ask where the gate sits relative to the sealing face. Do not reuse a preform nozzle layout.
Open fields
Steel, cycle and price wait until the drawing and the machine are confirmed.
Questions
Cap mold inquiries.
Do you publish a standard bottle cap mold specification?
No. Cavity count, steel, cycle and price follow the closure drawing, the resin, the sealing and opening requirements, and the injection machine. The public photographs are a 24 cavity front view and a 32 cavity mold. They are project views, not a complete specification.
How does a cap mold relate to the preform neck?
The closure screws onto the neck finish, and blow molding does not change that finish. PCO 1881, PCO 1810, 26/22, 29/25 and 30/25 are finishes discussed for water and drinks. The cap mold and the preform mold have to agree on the finish before either tool is cut.
Is a preform hot runner the same part as a cap hot runner?
No. A preform gate sits in the base of the preform. A cap mold gates into the closure, sometimes near a sealing face, and the part is ejected differently. Send the closure drawing and ask where the gate will sit.
What should I send with a cap mold inquiry?
The closure drawing, resin, appearance and sealing requirements, target cavity count or output, and the injection machine. If you already have a neck finish, name it. Unconfirmed fields are not replaced with a catalog default.
