Planning tool / reference-bottle warning

Water Filling Machine Capacity Planner

State required good bottles per hour on a named bottle, or calculate a preliminary rate from daily demand. Use planned production hours and one combined allowance for losses; do not subtract the same downtime from hours and count it again in the efficiency factor.

Calculate one transparent planning requirement

Required nominal BPH = daily good bottles ÷ planned production hours ÷ assumed effective-output factor, multiplied by any separately selected future reserve. Record the assumptions with the result so bidders are responding to the same requirement.

Use hours allocated to production before the losses included in your factor.
The factor covers the losses you choose to model; it is not a verified machine efficiency.
Apply future demand reserve separately, not a second allowance for the same stops.

Do not count the same loss twice

If downtime has already been removed from the hours, do not include that same downtime again in the effective-output factor. Either use planned hours with a combined factor, or document a different consistent basis. A 100% factor is an idealized arithmetic case, not a promise of loss-free production.

Name included downtime, speed and reject assumptions.
Keep planned output separate from measured operating results.
Review changes in demand, shifts and formats explicitly.

Tie the requirement to a reference bottle

Send the bottle volume, drawing, neck and closure with the calculated rate. Filling time, handling and capping can change across formats. Neither litres per hour nor a model number is enough to establish acceptable bottles per hour for every SKU.

Ask the supplier to return evidence, not just a bigger number

Request the proposed rated output, necessary supply conditions and a test method that records acceptable bottles over time. Keep stops, rejects and open deviations visible. Select the final configuration only after scope, interfaces and acceptance are agreed.

Supplier capacity evidence

How to verify a water filling machine supplier's capacity claim

Two suppliers quoting the same BPH are not comparable until they use the same bottle, cap, test duration, good-output count, reject rule and equipment boundary. Calculate a planning rate first, then make every supplier state how that rate will be demonstrated.

Direct answer: treat quoted BPH as a supplier claim until it is tied to an approved reference bottle and cap, a defined stable-run period, counted good bottles, written reject criteria and the exact machine or connected-equipment boundary. That evidence belongs in the technical proposal and FAT protocol.

Evidence required to normalize supplier BPH claims
Comparison field	Buyer instruction	Evidence to retain
Rated BPH	State the exact reference SKU and operating condition.	Technical proposal with assumptions
Reference bottle and cap	Provide approved drawings, weight, neck finish, closure and samples.	Signed sample or drawing register
Test duration	Define warm-up, observation period and permitted interruptions.	FAT protocol and time-stamped run record
Good output	Count accepted bottles, not only filler revolutions or bottles entering the machine.	Good-count and reject-count sheet
Reject definition	List underfill, overfill, missing cap, bad torque, leakage and damaged bottles.	Inspection method and retained samples
Changeover condition	Name the installed format and any change parts used during the test.	Approved format and change-parts list
System boundary	Identify infeed, water supply, cap feed, outfeed and downstream constraints.	Interface schedule and stop responsibility
Open assumptions	Separate planning efficiency and future reserve from demonstrated output.	Deviation and assumption register

Turn daily demand into one supplier comparison basis

Use saleable bottles, not nameplate output, as the planning target. Illustrative calculation: 40,000 good bottles in eight planned production hours at an assumed 80% effective-output factor requires 40,000 ÷ (8 × 0.8) = 6,250 nominal BPH before any future reserve. Apply downtime, speed and reject losses once: do not subtract the same downtime from the hours and count it again in the factor. This arithmetic is not a machine recommendation or a promised efficiency.

State the reference bottle

Capacity must name bottle volume, drawing, weight, neck finish and cap. A 500 ml rating cannot be copied to 1.5 L or large-format bottles without confirmation.

Separate rated and good output

Ask for rated BPH, demonstrated test output, reject definition, test duration and the condition under which stable output is accepted.

Balance the complete line

Water supply, bottle feed, labeling, coding, packing and conveyors must sustain the agreed rate; the slowest connected process limits saleable output.

Keep reserve visible

Record the planning efficiency and future reserve separately. Do not hide them inside an unexplained oversized machine recommendation.

Carry result to RFQ

Formula: daily good bottles ÷ planned hours ÷ effective-output factor, then add the selected future reserve. Apply downtime, speed and reject losses once; do not double-count losses already removed from hours. The fill-volume result is not a total water-utility requirement. This is preliminary planning, not a machine recommendation. Final output requires confirmation on the actual bottle, cap and connected equipment.
