MOLD SUPPLY / CONFIGURATION / MATCHING
Plastic Cup Injection Molds
Mold supply and configuration for PP and PS plastic cups — drinking cups, yogurt cups, milk-tea cups and IML cups. Each plastic cup mould is reviewed around your cup geometry, cavity layout, filling, cooling, take-out and machine, then quoted with a defined supply scope and sample acceptance requirements.

01 / THE PRODUCT TO MOLD
What plastic cup do you need to mold?
Share the actual cup, not only its capacity. A sample helps define the shape, finish, lid interface and any design changes.
YOUR CUP DESIGN
Start with your actual sample
Send side, top and base photos, or a product drawing. Include the matching lid when fit or sealing must follow an existing design.
- Cup material and dimensions
- Part weight and wall section
- Rim, lid and stacking requirements
- Standard or IML decoration
02 / CUP MOLD OPTIONS
Cup mold options
Recorded cup mold examples with cavity count and cycle time.
| Cup type | Cavities | Cycle time |
|---|---|---|
| PS airline cup | 24 | 5.9 s |
| PS tea cup | 16 | 7.0 s |
| Crystal cup | 12 | 8.0 s |
To match a cavity concept to a machine, compare the SP6 models on the high-speed page.

How to choose cavity count and machine
Work backward from your output target. Compare cavity concepts against mold space, filling, heat removal and take-out, rather than choosing more cavities by default.
Shape & material
Resin grade, diameter, height, weight, wall section and bottom geometry.
Interfaces
Rim, existing lid, sealing surface and stack / nesting requirements.
Decoration
Surface finish, label area and IML requirements if applicable.
- 01Output target → cavity concept
- 02Mold size + injection volume
- 03Projected area + machine requirement
- 04Cooling + robot / IML arrangement
01 / PHYSICAL FITCan the mold be installed and operated?
02 / PROCESS FITCan it meet the cup’s process requirements?
- Machine brand and model
- Tie-bar spacing and platen dimensions
- Mold thickness range and opening stroke
- Nozzle interface and take-out space
- Clamping force and projected area review
- Injection capacity for the selected material
- Filling capability for the cup and cavities
- Cooling, ejection and robot interfaces
04 / FILLING, COOLING & RELEASE
Filling, cooling and release
Thin-wall cup production depends on filling balance, heat removal and release working together. Review the mold and the selected machine as one system.
PRODUCTWall section + flow length
MOLDGating + balance + venting + rigidity
MACHINEFilling capability for the selected cup and cavity concept
Sticking & rim damage
Check release behavior and the condition of the molded sample.
Repeatable transfer
Coordinate the selected release method with the take-out approach.
05 / IML & TAKE-OUT
IML and take-out
IML compatibility starts with label area and cup geometry. Review how the label is placed, retained and released with the cup.
LABEL ↔ CAVITY ↔ TAKE-OUT
Review the interfaces together
- Label area and cavity geometry
- Label placement and retention
- Robot access and part release
- Machine / automation cycle coordination
Confirm IML suitability for the selected mold concept.
- 01Opening + access envelope
- 02Cup release + gripper approach
- 03Part and robot clear the mold
- 04Clearance / interlocks → closing enabled
06 / CUP + LID
An existing lid becomes part of the design brief
Provide the matching lid or drawing early. Rim geometry, material behavior and sample fit should be reviewed together.
LID SAMPLE / DRAWING↕CUP RIM + NESTING REQUIREMENTS
- Do you have an existing lid to match?
- What fit or sealing result must be achieved?
- Is a new lid mold also part of the request?
- What stack or nesting requirement should be checked?
Include any matching lid-tooling request in the quotation brief so its scope and interfaces can be reviewed.

09 / MOLD BUYER QUESTIONS
Plastic cup mold FAQ
What information is required to quote a plastic cup injection mold?
Send a cup photo or drawing, material, dimensions, weight and wall section if known. Include lid and IML requirements, target output and details of the intended machine. Cavity count can be evaluated during the configuration review.
How do I choose the cavity count for a plastic cup mold?
Start with the required output and available production time. Compare cavity concepts against mold size, total shot, projected area, filling capability, cooling and take-out requirements. A larger cavity count is not automatically a better fit.
What mold features matter for thin-wall plastic cups?
Review the relationship between wall section, flow length, gating, filling balance, venting and mold rigidity. Cooling, release and machine filling capability also influence whether the cup can be produced consistently.
Can a plastic cup mould be configured for IML?
IML suitability depends on the cup and label geometry. Review label area, placement and retention, cavity access, release and machine–robot coordination before confirming the mold configuration. IML is not assumed for every mold.
Can HWAMDA match a cup mold to my existing injection molding machine?
Yes, machine–mold matching can be reviewed before ordering. Send the machine brand, model, clamping and mold-space specifications, injection capacity, nozzle details and opening stroke. Final compatibility requires both physical and process review.
Can I order only the mold?
Yes. HWAMDA supports mold-only orders with the cup requirements and intended machine reviewed together. The quotation defines mold configuration, supply scope and sample acceptance requirements.
Can the machine and mold be supplied together?
The machine and mold can be coordinated as a project. If you also need cooling, automation and material handling, the Plastic Cup Injection Molding Solution page covers that broader production-cell task.
What if I have a cup sample but no drawing?
Upload clear photos from the side, top and bottom, with a scale reference where possible. Provide the sample dimensions, weight, material if known, lid or mating sample, and the changes you want. Describe how a physical sample can be made available for review.
How does cooling affect high-speed cup mold performance?
Core and cavity heat removal influences dimensional consistency and release. Uneven or insufficient cooling can limit cycle stability even when the machine can fill quickly. Review the mold and available cooling-water supply together.
Can the mold be configured to match an existing lid?
Provide the actual lid or its drawing and identify the fit and sealing requirements. The rim geometry and relevant material behavior should be reviewed and the fit checked with molded samples. Include nesting or stacking requirements in the product brief.
