Blister Packaging Machine Speed and Capacity Guide
Calculate the cycle rate from your accepted-pack target, packs per stroke, scheduled run time and a verified operating factor. Then confirm the selected configuration with your product, materials and FAT protocol.
1. Define the packFinished packs per stroke, not an ambiguous BPM label.
2. Set the conditionsProduct, material, tooling, inspection and line interfaces.
3. Accept the outputGood packs during an agreed FAT run, with stops and rejects recorded.
Define the unit first
Cycles, packs and product units are different capacity measures
A speed figure is useful only when the supplier states what it counts. Put the machine cycle, approved layout and accepted finished output on the same comparison sheet.
Approved web layout
How many finished blister cards the approved forming and cutting layout produces in one cycle.
Saleable product count
How many tablets, capsules or other units are contained in each accepted blister card.
Nominal format output
Cycle rate multiplied by finished packs per stroke before real operating losses are applied.
Usable measured output
Finished packs that meet the agreed inspection and quality criteria during the defined test.
Production planning output
Accepted packs multiplied by units per pack and actual scheduled operating minutes.
Core relationship: mechanical packs/min = cycles/min × finished packs/stroke. Accepted packs/min = mechanical packs/min × your verified operating factor. Do not treat pockets, packs and cycles as interchangeable.
| Term on a supplier sheet | What the supplier must state | Procurement interpretation |
|---|---|---|
| Maximum speed | Whether the figure means cycles, strokes, finished packs or product units per minute | Do not compare the number until the counted unit and test condition are written beside it. |
| Output | Approved product, material, format, packs per stroke and test duration | A format-specific result cannot be transferred automatically to a different blister layout. |
| Cavities per stroke | Number of individual product pockets and how they are grouped into finished cards | Pockets per stroke is not always the same as finished packs per stroke. |
| Usable web width | Material width available after edge allowances, registration and cutting requirements | Nominal forming width alone does not prove the proposed card arrangement will fit. |
| Efficiency or OEE | Formula, observation period, included losses, product mix and data source | Reject a percentage that has no numerator, denominator or operating boundary. |
| Changeover time | Defined start and finish points, cleaning scope, tooling included and release checks | Compare observed tasks, not one headline duration based on different boundaries. |
| Line speed | Which machine controls the line rate and what accumulation is available | The filler, printer, vision system, cartoner or manual handling step may become the constraint. |
Normalize every quotation
Create one comparison column for cycles/min, one for finished packs/stroke, one for nominal packs/min and one for accepted packs/min. Keep product units per pack in a separate field so the same number is never counted twice.
Keep the evidence attached
Link each capacity figure to its format drawing, material specification, test run or stated planning assumption. A number without its evidence and boundary should remain provisional.
Planning calculator
Calculate the minimum cycle rate from your own production plan
Enter accepted finished packs, not tablets or empty cavities. The operating factor must come from your line history, a representative trial or an agreed planning assumption; this calculator does not insert a universal default.
| Calculation step | Formula | Source to use | Check before approval |
|---|---|---|---|
| Scheduled minutes/year | Production days × shifts/day × scheduled minutes/shift | Approved production calendar | Remove planned non-production periods only once. |
| Required accepted packs/min | Annual accepted packs ÷ scheduled minutes/year | Demand plan in finished saleable packs | Confirm whether the target includes growth, rejects or inventory policy. |
| Required mechanical packs/min | Accepted packs/min ÷ operating factor | Documented planning or trial factor | State which losses the factor includes and which are modeled separately. |
| Required cycles/min | Mechanical packs/min ÷ finished packs/stroke | Approved tooling drawing | Use finished cards after cutting, not individual pockets unless the target uses pockets. |
| Required product units/min | Accepted packs/min × accepted product units/pack | Approved market pack | Use this only for downstream tablet or capsule counts; do not substitute it for pack output. |
Forward calculation
Start from the annual accepted-pack target and work toward a minimum cycle rate. Use this for early URS and budget screening.
Reverse capacity check
Start from the supplier's proposed cycle rate and layout: cycles/min × packs/stroke × operating factor × scheduled minutes. Compare the result with required accepted packs, using the same time basis.
Margin review
Keep required output, proven output and unused capacity as separate fields. Do not hide an untested growth allowance inside the operating factor.
Result boundary: the calculation is a planning minimum, not a guaranteed machine output. The selected model still needs enough cycle capability for the approved material and format, plus a representative FAT run that measures accepted packs.
Source-verified machine reference
DPP-250F cycle data shows why material and format must be named
The values below are transcribed from the DPP-250FⅠ operating manual supplied to HIJ. They are machine-cycle and format data, not a promise of finished blister packs per minute.
| Manual parameter | Published value | Capacity-planning use |
|---|---|---|
| Maximum punch frequency | Alu/Alu: 20–30 cycles/min Alu/Plastic: 20–50 cycles/min | Select the relevant material route before comparing cycle rate. |
| Manual reference format | 57 × 80 mm × 4 | Confirm the meaning and final packs-per-stroke layout on the approved tooling drawing. |
| Stroke range | 30–120 mm | Format pitch changes material advance and tooling design. |
| Maximum forming area | 250 × 112 mm | The pack geometry must fit the usable forming and cutting arrangement. |
| Maximum formed depth | Alu/Alu: 12 mm Alu/Plastic: 18 mm Special configuration: 25 mm, subject to confirmation | Product and forming material affect the feasible cavity design. |
Excluded source row: the manual contains a separate maximum-production-capacity entry with an internally inconsistent unit. It is intentionally not published or converted here. Finished output must be calculated from approved packs per stroke and confirmed by trial.
Use the correct material row
The manual lists different punch-frequency ranges for Alu/Alu and Alu/Plastic. A quotation should identify the material route beside the proposed cycle rate.
Approve the actual layout
The 250 × 112 mm forming area and 30–120 mm stroke describe machine limits. They do not replace a tooling drawing that shows web direction, pitch, pockets and finished packs per stroke.
Separate capability from acceptance
A value transcribed from a manual is evidence of published machine capability. Accepted project output still belongs in the technical agreement and FAT protocol.
| DPP-250F supporting parameter | Published value | Why it belongs in the capacity review |
|---|---|---|
| Total installed power | 7.5 kW at 380 V / 50 Hz; the manual also lists 220 V / 60 Hz | Confirm the final electrical configuration before the cycle test and site installation plan. |
| Air pump volume flow | At least 0.25 m³/min | Available compressed air must support the agreed machine configuration during the test. |
| Overall machine size | 3360 × 610 × 1670 mm | Allow space for operators, material rolls, product feeding, cleaning and access to the tested stations. |
| Machine weight | 1500 kg | Include foundation, access and installation planning in the project boundary rather than treating capacity as a standalone number. |
From rated cycles to accepted output
Six conditions determine the operating factor for your blister line
There is no defensible universal efficiency percentage for every product, material and plant. Build the factor from defined losses and replace planning assumptions with measured data as soon as trial evidence is available.
Product feeding
Tablet, capsule or device geometry affects orientation, feeding stability, empty-pocket risk and the speed at which inspection can remain effective.
Forming material
PVC-based thermoforming and cold-form aluminium use different forming conditions. Compare cycle rates only within the approved material route.
Pack layout and tooling
Pitch, web width, cavity geometry, packs per stroke and cutting arrangement determine how cycle rate becomes finished packs.
Sealing and inspection
The accepted operating window must maintain seal quality and allow the specified checks and reject logic to work at the test rate.
Changeover and cleaning
Format changes, line clearance, cleaning, sampling and replenishment reduce scheduled running time. Record them separately from in-run rejects.
Downstream line balance
Printing, vision, perforation, cartoning and accumulation can limit accepted line output even when the blister machine can cycle faster.
| Process station | What can limit sustained output | What to observe or request |
|---|---|---|
| Material unwind and registration | Web tracking, roll joins, tension, print registration and replenishment method | Approved material rolls, alignment criteria and roll-change procedure |
| Forming | Heating or cold-form conditions, cavity definition, web advance and formed-pocket consistency | Operating window by material and samples from the agreed test rate |
| Product feeding | Orientation, bridging, dust, breakage, empty pockets and replenishment | Representative product trial and counted feed-related stops or rejects |
| Inspection and reject | Detection threshold, false rejects, challenge test, reject confirmation and bin capacity | Cause-and-effect list, challenge samples and physical reject evidence |
| Lidding and sealing | Material compatibility, temperature, pressure, dwell and web stability | Defined seal test method and samples across the planned operating range |
| Printing and coding | Print speed, code quality, registration, data handoff and verification | Approved code sample and readable output at the agreed line rate |
| Perforation and cutting | Registration, cut position, burrs, card separation and scrap handling | Finished-card dimensions and defect criteria on the signed format drawing |
| Discharge and downstream handling | Card transfer, accumulation, manual collection, cartoner infeed and line stops | Line-balance diagram, interface ownership and downstream acceptance rate |
Find the constraint at the required rate
Run the complete process at the proposed cycle rate. A defect found at cutting or discharge may start earlier at forming, feeding, sealing or registration, so the event log should retain the first observed cause.
Test the planned operating range
One short run at maximum speed does not define a stable process window. Agree which lower, normal and upper operating points need evidence for your qualification work.
Comparison rule: ask every supplier to quote the same product, material, format drawing, accepted-output definition, test duration and downstream boundary. A faster nameplate is not a better comparison when the test conditions differ.
Quotation and FAT evidence
Put the same capacity boundary into the URS, quotation and FAT protocol
A useful speed acceptance test states what runs, how output is counted and which events stop or invalidate the run. Define those items before comparing offers.
| Capacity item | Required definition | Evidence to retain |
|---|---|---|
| Test product | Approved product or named substitute, with dimensions and feeding conditions | Sample identification and trial record |
| Forming and lidding material | Grade, thickness, width, supplier and printed-registration requirement | Material specification and roll identification |
| Approved format | Pocket layout, packs per stroke, pitch, cut profile and product units per pack | Signed tooling or format drawing |
| Test rate and duration | Machine cycles/min, scheduled test period and any ramp-up allowance | HMI record and timed run sheet |
| Accepted output | Good packs produced, with the agreed inspection and seal criteria | Counted output, inspection results and sample set |
| Loss record | Stops, starvation, jams, rejects, adjustments and downstream holds | Event log with reason and duration |
| Changeover | Start and finish points, cleaning boundary, parts changed and release checks | Observed changeover record; do not hide it inside run efficiency |
Supplier quotation
Request cycle range by material, packs per stroke for the quoted format, included tooling, inspection scope and the conditions used for any stated output.
Buyer acceptance
Approve the required accepted packs, test method, reject counting, evidence package and responsibility for upstream or downstream limits.
Machine and pack output
Record cycles/min, finished packs/stroke, nominal packs/min and accepted packs/min as separate values.
Accepted versus rejected packs
Count seal, forming, feeding, print, inspection and cutting defects using agreed categories.
Running, stopped and excluded time
Record the test clock, every stop and any excluded setup period so the denominator remains auditable.
| Approval gate | Question to close | Responsible evidence |
|---|---|---|
| Before quotation | Are all suppliers pricing the same pack, material, output target and line boundary? | Buyer RFQ plus supplier inclusion and exclusion schedule |
| Before tooling release | Does the signed drawing show the exact pockets, finished packs, pitch, web width and cut profile? | Approved format drawing and sample reference |
| Before FAT | Are test product, materials, speed points, duration, sampling and acceptance criteria agreed? | Approved FAT protocol and test-material list |
| At FAT completion | Did the machine produce the required accepted output with recorded stops and rejects? | Signed result sheet, samples, logs and open-item list |
| Before shipment | Are unresolved items closed or controlled by a dated action plan? | Closure evidence, packing list and approved shipment release |
| At site | Can utilities, operators and downstream equipment reproduce the agreed operating conditions? | Site acceptance and qualification records under the buyer's process |
Measured operating factor
Build the operating factor from a loss log, not a universal percentage
A planning factor becomes useful when another engineer can reproduce it. Define the time boundary, record each loss once and keep quality loss separate from time loss. Replace assumptions with measured results after trials and production history become available.
Planned production time
Start with the time the blister line is scheduled to produce. State whether breaks, planned cleaning, maintenance and changeover have already been removed.
Operating time
Subtract recorded stops inside the defined production window. Keep each event reason and duration so the same stop is not charged to several categories.
Accepted-pack output
Count only finished cards meeting the agreed forming, filling, sealing, printing, cutting and inspection criteria.
| Loss category | Examples to record | Recommended field | Capacity decision |
|---|---|---|---|
| Setup and ramp-up | Tooling adjustment, material threading, temperature stabilization and first-piece approval | Start time, finish time and release checkpoint | Keep separate when the objective is stable in-run output; include it when planning complete batch time. |
| Material supply | Roll change, lidding replacement, product replenishment and waiting for released material | Reason, duration and responsible interface | Decide whether the quoted system includes automatic feeding or accumulation. |
| Process stop | Forming fault, feed jam, sealing adjustment, registration loss or cutting fault | First observed cause, affected station and duration | Use repeated causes to set corrective actions or change the proposed configuration. |
| Inspection and reject | Empty pocket, damaged product, poor seal, unreadable print, cut defect or failed challenge | Reject category and counted quantity | Compare accepted packs rather than gross machine cycles. |
| Downstream hold | Printer, vision, cartoner, manual collection or discharge congestion | Constraint equipment and blocked/starved duration | Resolve line balance or add a defined accumulation strategy. |
| Changeover and cleaning | Line clearance, part removal, cleaning, reassembly, format setup and release | Boundary, tasks, people and elapsed time | Model campaign length and SKU mix separately from the stable-cycle test. |
Transparent calculations:
Time operating factor = operating minutes ÷ planned production minutes.
Quality acceptance factor = accepted packs ÷ total finished packs produced.
Combined accepted-output factor = accepted packs ÷ nominal packs possible during planned production time.
Use only one method in a comparison and state whether setup, changeover and cleaning sit inside or outside its boundary.
Time operating factor = operating minutes ÷ planned production minutes.
Quality acceptance factor = accepted packs ÷ total finished packs produced.
Combined accepted-output factor = accepted packs ÷ nominal packs possible during planned production time.
Use only one method in a comparison and state whether setup, changeover and cleaning sit inside or outside its boundary.
For a new line
Begin with a labeled planning assumption and show sensitivity at more than one factor. Do not present the assumption as proven equipment performance.
For an existing line
Use a representative product mix and enough observations to expose recurring losses. Keep unusual events visible instead of deleting them to improve the average.
Capacity brief for quotation
Send one normalized input sheet to every blister machine supplier
The fastest way to obtain comparable proposals is to remove ambiguity before suppliers select a model. Use the same pack, material, production calendar and acceptance boundary in every RFQ.
| RFQ input | What to provide | Why it changes capacity |
|---|---|---|
| Product | Tablet, capsule or device type; dimensions; shape; fragility; dust; representative samples | Controls feeding, orientation, handling and inspection behavior. |
| Finished pack | Approved drawing, pocket count, card dimensions, perforation and cut profile | Determines packs per stroke and tooling arrangement. |
| Forming material | Material structure, thickness, width, supplier and barrier requirement | Changes forming method, operating window and feasible cycle range. |
| Lidding material | Structure, seal coating, thickness, print status and supplier | Affects sealing conditions, registration, printing and inspection. |
| Production target | Accepted packs per batch, shift, day and year | Prevents product units, pockets and finished packs from being mixed. |
| Calendar | Production days, shifts, scheduled minutes, campaign length and SKU mix | Converts annual demand into an auditable rate and changeover burden. |
| Operating factor | Planning assumption or measured basis, included losses and observation period | Connects nominal mechanical output with accepted production output. |
| Inspection | Missing-product checks, vision/OCR, code verification, reject logic and records | Adds processing, validation and physical reject-handling requirements. |
| Interfaces | Product feeder, printer, vision, cartoner, utilities, data and accumulation | Defines the line constraint and responsibility at each handoff. |
| Changeover | All planned formats, cleaning method, target boundary and release checks | Determines non-running batch time and the required tooling set. |

Capacity questions
Blister packaging machine speed FAQ
What is the difference between cycles per minute and packs per minute?
Cycles per minute is the machine index or stroke rate. Packs per minute also depends on how many finished blister cards the approved layout produces per stroke. Multiply cycles per minute by finished packs per stroke to calculate nominal mechanical packs per minute.
How do I calculate the blister machine cycle rate I need?
Divide the required accepted packs by scheduled production minutes to obtain accepted packs per minute. Divide that result by your documented operating factor, then divide by finished packs per stroke. The result is the minimum planning cycle rate before a supplier confirms the material, format and test conditions.
What operating factor should I use?
Use a value supported by your line history, a representative product trial or an agreed planning assumption. State what it includes. Product feeding, material behavior, inspection, rejects, replenishment, changeover and downstream holds vary by project, so this guide does not apply one universal percentage.
What is the published DPP-250F cycle rate?
The supplied DPP-250FⅠ manual lists 20–30 cycles/min for Alu/Alu and 20–50 cycles/min for Alu/Plastic. These are material-dependent punch frequencies. Finished packs per minute still require the approved packs-per-stroke layout and measured operating conditions.
Why can accepted output be lower than the nominal calculation?
Accepted output excludes packs that fail the agreed quality and inspection criteria. It can also be limited by feeding, forming, sealing, printing, vision, reject handling, material replenishment and downstream equipment. Record these events during the FAT run instead of hiding them inside one unexplained efficiency number.
What should I send HIJ for a capacity review?
Send the product and sample, forming and lidding materials, finished blister drawing, packs and product units per stroke, annual or shift output target, production calendar, inspection scope, downstream equipment and the FAT acceptance method you expect.
Does a larger forming area always mean higher blister output?
No. A larger forming area can allow a different layout, but finished output still depends on usable web width, pitch, cavity and card geometry, packs per stroke, material behavior, cycle range and cutting arrangement. Approve the actual tooling drawing instead of calculating capacity from maximum forming area alone.
How should I compare Alu/Alu and thermoforming blister machine speed?
Compare them as different material and forming routes. State the proposed cycle range for the approved material, then calculate finished packs from the corresponding layout. Do not apply a universal percentage reduction or compare an Alu/Alu result with a thermoforming result that uses different products and formats.
Should changeover and cleaning be included in the operating factor?
Either approach can work if the boundary is explicit and consistent. For stable in-run output, record changeover and cleaning separately. For full batch-capacity planning, include their elapsed time in the schedule. Do not subtract the same loss in both the available minutes and the operating factor.
Can a faster blister machine solve a downstream bottleneck?
Not by itself. Printing, inspection, reject handling, cartoning, accumulation or manual collection can cap accepted line output. Define the controlling machine, accumulation strategy and interface responsibilities, then test the complete boundary at the required rate.
