Exact model review
This page shows the product details behind a 24-cavity water bottle preform mold. The final configuration is built from the approved preform drawing, the exact injection machine and an agreed trial and acceptance plan.
Cavity selection
24 cavities is best suited to controlled production demand
Shortlist 24 cavities when the demand case and plant resources favor a controlled production step.
Investment discipline matters
The buyer prefers to keep mold, machine, controller, spares and maintenance complexity aligned with current demand rather than pay for unused capacity.
Maintenance simplicity has value
The plant wants fewer cavities and runner components to inspect, service and stock while the product program is still developing.

Product definition
What this 24-cavity mold must produce
Cavity count is only one line of the specification. The approved water-bottle preform defines the neck, weight, resin, cooling demand, shot requirement and acceptance method.

Mold construction
Turn available options into a defined mold specification
The 24-cavity specification records the material, alignment, cooling and runner design used for the approved preform and injection machine.
View imageMold stack material
Available design option
The 24-cavity material schedule uses a 420 stainless-steel mold base and M333 cores, cavities and neck rings hardened to HRC 48-51. Heat treatment is performed using German Ipsen equipment.
Project confirmation
The approved mold drawing records the lock-ring material, surface treatment and final material schedule for the selected preform.
Core and neck alignment
Available design option
Taper matching between the core and lock ring, together with a double-taper neck-ring structure, is an available design approach.
Project confirmation
The approved mold drawing must show the selected alignment and replaceable-component structure.
Cavity cooling
Available design option
Spiral independent cavity-water circuits are an available cooling approach for controlling heat removal at each cavity.
Project confirmation
Circuit layout and required water temperature, pressure and flow remain project-specific.
Hot runner balance
Available design option
The available hot-runner component package uses HOTSET heaters from Germany with PCT nozzles and insulators from the United States.
Project confirmation
The proposal must define runner type, valve-gate actuation, zones, controller, connectors and service parts.

Match the circuit to the plant water
Cooling claims only become useful when circuit layout and the buyer's actual water temperature, pressure, flow and quality are considered together.

Machine and output
Prove fit before using an output number
A 24-cavity mold may be reviewed for a general-purpose injection platform, but the conclusion must use the exact injection unit, mold envelope, controls and utilities.
Injection unit
Total shot, screw diameter, injection pressure and plasticizing capacity
Mold envelope
Platen size, tie-bar spacing, mold height range and mounting pattern
Mold movement
Opening stroke, daylight, ejector or take-out clearance and handling method
Hot runner control
Temperature zones, connectors, controller capacity and valve-gate actuation
Plant utilities
Cooling-water temperature, pressure, flow, air, hydraulic and electrical interfaces
Production basis
Approved preform, PET resin, verified cycle, operating hours and utilization target

Enter weight and output
The result will show the cycle ceiling and part mass for 24, 32, 48, 64, 72 and 96 cavities. A specific recommendation appears only when a verified cycle is entered.

The comparison does not predict cycle from preform weight. Wall thickness, geometry, PET resin, cooling water, hot runner, machine performance and quality requirements must be reviewed separately.
24 versus 32 cavities
Compare the neighboring option on the same part basis
The extra eight cavities are useful only when they solve a real capacity requirement and the exact machine, runner, cooling and maintenance scope can support them.
| Decision factor | 24 cavities | 32 cavities | What to verify |
|---|---|---|---|
| Parts per cycle | 24 preforms | 32 preforms | At the same cycle and utilization, 32 cavities produces 33.3% more parts per cycle. |
| Part shot basis | 24 x approved preform weight | 32 x approved preform weight | Add the project process allowance and verify the exact injection unit for either option. |
| Mold and machine | 24-cavity envelope and interfaces | Larger cavity set to be checked | Do not assume the same platen, mold height, opening or take-out conclusion. |
| Runner and controls | 24-drop runner and control layout | 32-drop runner and control layout | Compare zones, actuation, spare parts and service access, not only mold price. |
| Selection trigger | Meets demand with operating margin | Extra capacity solves a proven demand gap | Choose from useful annual output and machine fit rather than cavity count alone. |
Trial and acceptance
Make the shipment decision from traceable evidence
The acceptance plan should connect the approved part to the exact trial machine and conditions, then review samples from all 24 cavities before packing.
01
Freeze the part basis
Approve the preform drawing, neck finish, weight, PET grade and visible quality requirements.
02
Confirm machine interfaces
Close the shot, platen, tie-bar, mold-height, control, utility and take-out checks before final design.
03
Define the trial condition
Run the mold on the agreed injection machine with the agreed PET resin, and record the machine, cooling-water condition, process settings and verified cycle.
04
Check all 24 cavities
Confirm normal molding from all 24 cavities and supply one complete cavity-identified sample set. Check neck dimensions, weight, gate, appearance, flash and short shots.
05
Close shipment evidence
Provide the trial video and basic inspection records, complete bottle-blowing acceptance when required, then confirm samples, documents, spares, rust prevention and export packing.

These photographs show practical sample checks. Final records must link each result to the approved preform, trial condition and cavity identification.

Buyer questions
24-cavity technical FAQ
These answers set the review method. Exact project values remain tied to the approved drawing, machine and trial conditions.
01What information is required for a 24-cavity PET preform mold quotation?
Start with the preform drawing or sample, bottle application, neck finish, preform weight, PET resin, required output and injection machine model. Any missing machine data can then be completed during technical review.
02Can a 24-cavity PET preform mold run on a general-purpose injection machine?
A general-purpose platform may be reviewed, but compatibility cannot be decided from clamping tonnage alone. Total shot, plasticizing capacity, tie-bar spacing, platen, mold height, opening, hot-runner controls, cooling and take-out must all be checked against the exact machine.
03Which neck finishes can be reviewed for this 24-cavity mold?
The confirmed water-bottle neck program includes PCO 1881, PCO 1810, 29/25 and 30/25. The approved preform and closure drawing decides the exact neck used in the project.
04How is realistic 24-cavity output calculated?
Use 24 multiplied by 3,600 and divide by the verified cycle in seconds, then multiply by expected utilization. Daily and annual output also require the planned operating hours and days. The cycle must come from the actual part, resin, machine, cooling and trial conditions.
05When should I compare 24 cavities with 32 cavities?
Compare both when 24 cavities meets demand with little operating margin, when the exact machine may support 32 cavities, or when near-term growth makes the additional eight parts per cycle useful. Keep the preform, cycle and utilization basis identical in the comparison.
06What should be checked before the mold is shipped?
Run the mold on the agreed machine with the agreed PET resin, confirm normal molding from all 24 cavities, identify a complete 24-piece sample set by cavity, inspect neck dimensions, weight, gate, appearance, flash and short shots, provide the trial video and basic inspection records, and complete bottle-blowing acceptance when required.
