High-output beverage lid tooling
Hengqi develops 12CAV coffee cup lid moulds for buyers who need higher lid output without losing rim fit, flatness or maintenance control. Send the lid drawing plus physical cup-and-lid samples so cavity balance, venting, cooling, stacking, ejection and independent insert service access can be reviewed before quotation.

03 / Visual engineering story
Each stage below pairs the engineering decision with a real product, tooling or factory image. This makes it easier to understand what Hengqi will review and manufacture for the project.
01 / Lid tooling structure
The insert strategy is reviewed around the cup rim, cooling channels, venting and later service access. A modular layout can make local fit correction and cavity maintenance more practical without weakening the mould structure.
02 / Precision machining
Precision machining protects the relationship between the snap ring, sipping features, vents and assembly interfaces. Stable insert geometry reduces correction work when the matching cup is checked during trial.
03 / Hot runner & balance
The runner route, gate selection and temperature control are reviewed with the thin lid geometry. The objective is consistent filling and weight across cavities while keeping gate appearance and maintenance access under control.
04 / Trial & fit validation
During trial, all 12 cavities are checked for flatness, rim fit, release force, sip and vent completion, stacking and ejection. Continuous running then confirms that the result remains stable beyond the first few shots.
01 / Engineering review
A useful tooling proposal must connect the product, resin, machine, automation and output target. These review points make the quotation more specific and reduce correction loops after steel is ordered.
The matching cup rim, snap ring, sealing surface and release force are reviewed together across the full 12-cavity layout. A lid drawing alone may not reveal the real fit requirement.
Gate position, wall distribution and cooling layout are reviewed to reduce warpage that can weaken sealing, stacking or automatic packing at higher output.
Drink opening geometry, vent features and thin local sections are checked for complete filling, demoulding and consumer use.
Runner geometry, gate selection and cooling consistency are matched to the 12CAV layout so lid weight, vent filling and rim fit stay stable across cavities.
The ejector route is reviewed around lid flexibility, deformation risk, robot pick-up and downstream stacking requirements.
Independent inserts can simplify cavity service, reduce correction time and protect uptime when a rim, vent or drinking-slot detail needs local maintenance.
02 / Tooling evidence
The images below are real Hengqi tooling or production references. They show the type of mould structure and manufacturing capability used for application review; the final tooling layout is customized to the actual product.
04 / Project workflow
The project route connects product approval, design, steel, machining, assembly and trial. Exact timing depends on mould complexity, cavity layout, steel and customer approval speed.
Confirm matching cup rim, lid dimensions, resin, annual output, machine capacity, maintenance expectation and downstream handling.
Define cavity layout, insert strategy, hot runner, cooling, venting and ejection before steel order.
Manufacture inserts and mould components, then verify fitting, cooling and moving interfaces.
Trial with the matching cup and review 12-cavity balance, flatness, sealing fit, stack release, ejection and cycle window.
05 / Trial acceptance
Acceptance should reflect the product's actual job on the filling, packing or consumer-use line. Final criteria are confirmed with the buyer before trial.
Information needed for quotation
A drawing is best, but a clear sample photo and basic production information are enough for the first engineering review.
06 / Buyer questions
These answers provide a practical starting point. Final specifications are based on your drawing, samples, resin, machine and production targets.
Yes. The actual cup rim is the best reference for snap fit, sealing, release force and tolerance review across all 12 cavities. If physical samples are unavailable, send both cup and lid drawings.
It fits buyers with stable demand, suitable machine capacity and automation that can handle the higher output. If production demand is uncertain or product variants change often, an 8CAV mould may be easier to manage.
They can make local cavity service and later fit correction easier, especially when one rim, vent or drinking-slot detail needs attention. The insert layout must still protect cooling, strength and dimensional consistency.
Check lid fit on the real cup, flatness, sip and vent features, 12-cavity weight balance, stack release, ejection marks and stability during continuous production.
Share lid and cup drawings or samples, resin grade, lid diameter, target output, injection machine data, take-out automation, cycle target and the required fit or leak test.
