Large-format IML food packaging
A 2L bucket project must connect container stiffness, rim and lid fit, optional handle features, IML label holding, machine capacity and robot speed. Hengqi reviews these relationships before defining the mould structure and quotation.
Reference capacity
2 litre food, dairy or ingredient bucket
Decoration
Full-wrap or partial IML by product design
Cavity direction
Usually 1–2 cavities after machine review
Key interfaces
Rim, lid, optional handle and stacking
Material
Food-grade PP or project-specified resin
Automation
IML robot, part take-out and stacking matched to line
Suitable buyer applications
Dairy, ice cream and ingredient bucket manufacturers
Food packaging factories upgrading to IML
Producers needing 2L retail or food-service packs
Buyers developing bucket, lid and handle systems
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 / Working-steel geometry
Large bucket walls, rim geometry and optional handle-lug areas depend on controlled core and insert relationships. These components move into inspection and fitting with the functional datums still traceable.
02 / Mould-base preparation
Mould-base plates, mounting, cooling and ejector features are prepared against the released design. Stable datums reduce accumulated error when the core, cavity, hot runner and moving interfaces are assembled.
03 / Melt delivery
Manifold geometry, nozzle selection, gate position and temperature control are matched to the 2L bucket. Cooling and injection capacity are evaluated at the same time so cavity count remains practical.
04 / Robot & trial validation
Trial work checks bucket stiffness, rim and lid fit, handle areas, label placement, robot grip and nested release. The agreed production window is confirmed during continuous running rather than a short manual test.
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.
Ribs, draft, thickness distribution and resin are reviewed so the 2L bucket remains usable without unnecessary material.
Roundness, shrinkage, closure force and sealing geometry are reviewed with the matching lid and filling conditions.
If a handle is required, lug strength, assembly direction, local stress and stacking clearance must be included in the product review.
Label dimensions, overlap, holding method, robot access and ejection are matched to the larger product surface.
Projected area, shot size, injection speed, tie-bar spacing and cooling capacity determine the practical cavity layout.
Robot grip, part release, nested stacking and downstream packing are checked against the bucket shape and label surface.
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 bucket, lid, handle, label, resin, filling use, machine, robot and output target.
Define wall, rim, handle lugs, cavity layout, label holding, hot runner, cooling and ejection.
Machine and inspect core, cavity, inserts and interfaces, then assemble the mould system.
Review label result, weight, stiffness, rim and lid fit, handle areas, robot take-out, ejection and stacking.
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.
The larger projected area, shot weight, cooling demand, robot motion and mould size often make one or two cavities more practical. The final layout must be calculated from the actual machine and output target.
Yes. Handle lugs and assembly features can be engineered into the bucket, while the handle itself may use a separate mould and assembly route.
It is recommended because rim shrinkage, lid closure and sealing are easier to control when both products are reviewed together.
Check wall balance, stiffness, rim and lid fit, handle areas, label position, surface appearance, ejection, robot stability and stacked-product release.
Share the filled bucket weight, handle style, assembly method, lifting test, stacking load and transport condition so the lug geometry and local wall strength can be reviewed before tooling.
