Solution / Filling trials
Your formula.
Your fill weight.
Water-based capacity is a starting point. Confirm the actual fill weight and screw configuration with your own formula, filling process and functional trial.
01 / Understand the volume
Density changes the space a target weight needs.
02 / Run your own trial
Use the intended formula and filling conditions.
03 / Confirm the configuration
Review the evidence, then retest the proposed sample.
01 / Capacity, density & weight
Same target weight.
Different required volume.
Tatapack’s standard capacity reference uses water density. A formula can have a different density, so a water-based capacity reference does not directly confirm how many grams of your formula will fit.
Mass = density × volume
m (g) = ρ (g/mL) × V (mL)
Required volume = mass ÷ density
V (mL) = target net mass (g) ÷ ρ (g/mL)
| Hypothetical density | Target net mass | Required volume |
|---|---|---|
| 0.80 g/mL | 60 g | 75.0 mL |
| 1.00 g/mL | 60 g | 60.0 mL |
| 1.20 g/mL | 60 g | 50.0 mL |

Mathematical examples only. These values are not ADM75 capacity specifications, measured formula data or recommended fill weights. For the water comparison, 1.00 g/mL is an approximation; actual water density depends on temperature.
Lower density means more volume for the same weight. Higher density means less volume. Temperature, entrapped air, cooling or setting, usable space and filling technique also need to be assessed in the actual trial.
02 / Trial with the intended formula
Let the filling test
answer the fit question.
The customer or filling partner should use the intended formula and actual process conditions. A water check cannot replace a formula filling and functional test.
Step 01
Set the trial conditions
Identify the sample and screw configuration. Record the target net weight, formula reference, density if measured, filling temperature and intended filling orientation.
Step 02
Fill, set & measure
Run the intended process. Measure net fill weight using gross weight minus tare weight for the same component set. After the formula has cooled or set, record its position and any voids or shrinkage.
Step 03
Check movement
Operate the pack with the actual filled formula. Record advancement and retraction, visible movement at the screw hub and any slip, separation or incomplete travel.
Use a consistent weighing method. Changing caps, plugs or other weighed components between the tare and gross measurements changes the apparent net weight.
03 / Bottom-fill concept
Check where the formula
meets the screw hub.
In a bottom-fill process, the pack is filled from the base side in the specified trial orientation. Follow the filling method agreed for the supplied sample.
Observe the filling direction
The short clip shows a reference sample being filled with water. The demonstrated sample has not been identified as ADM75. Water does not demonstrate formula anchoring or retraction performance.
Use the images below to identify the area to inspect, then record the result with your own formula after cooling or setting.
Full coverage is a necessary checkpoint. It does not, by itself, establish successful retraction. Verify complete advancement and retraction with the actual filled formula.
04 / Measurement & configuration review
Record the datum.
Then review the geometry.
If the target fill or functional result is not achieved, the screw or central-hub geometry may need to be reviewed for the intended formula and fill condition. Agree the proposal from the trial evidence and verify it again on samples.
Measure H from two defined planes
Measure the distance from the bottom-opening reference plane to the top face of the central screw hub. Keep the sample orientation and component configuration consistent.
Send a clear photo showing both contact points and the caliper reading. Include the measured H value and identify the sample used.
The reference photographs illustrate the method and may show a different sample configuration from the ADM75 CAD exterior.
Match the configuration to the trial
Tatapack reviews the measured fill position and functional result before proposing a screw or central-hub configuration.
Repeat the filling and function trial with the proposed sample before confirming the final specification.
01 / Evidence
Share the trial data
Weight, process conditions, fill position and clear photos or video.
02 / Review
Agree a sample proposal
Confirm the applicable geometry and the required change.
03 / Verification
Repeat the trial
Retest the proposed sample with the intended formula and process.
05 / What to send back
A clear trial record makes
the next decision easier.
Share the following with your Tatapack contact so the fill result and any configuration proposal can be reviewed together.
Sample & H measurement
Record the model, sample ID and screw or hub version. Give the H value and photograph both reference planes, contact points and the caliper reading.
Target & measured net weight
Target grams, tare weight, gross weight and calculated net weight, using the same component set.
Formula & process conditions
Formula reference, measured density with temperature if available, filling temperature and filling method.
Position after cooling or setting
Photos showing the fill position, hub coverage, voids or shrinkage and when the images were taken.
Advancement & retraction video
Show the complete movement and the specific area where slip, separation or incomplete movement occurs.
Observed issue & desired result
Explain the actual result, target condition and any process constraints relevant to the review.
