A factory replacing manual case packing needs to translate its production target into product flow, case formation, loading, and closure requirements. The same 25 cases per minute can mean 150 cups per minute in a six-count case or 600 cups per minute in a 24-count case. Those projects place different demands on upstream packaging and product accumulation.
Shangbaotai's full-automatic noodles carton packing machine page states a maximum filling and packing speed of 25 cases per minute. Treat this as a published reference maximum. The page does not identify the case size, pack pattern, product, or test conditions supporting that figure. A purchase specification must establish the accepted output for each actual SKU.
This article concerns secondary packing of finished cup or bowl noodles into shipping cases. Start with the packed container and the required case contents, then define the equipment and interfaces needed to deliver closed, accepted cases.
Use this calculation before requesting a quotation:
Required accepted products per minute = target accepted cases per minute × products per case.
| Illustrative products per case | Case target | Required accepted product flow | Procurement implication |
|---|---|---|---|
| 6 cups or bowls | 25 cases/min | 150 products/min | Verify the proposed collation and closure at this case count. |
| 12 cups or bowls | 25 cases/min | 300 products/min | Check upstream accepted output and lane distribution. |
| 24 cups or bowls | 25 cases/min | 600 products/min | Confirm product supply, accumulation, loading pattern, and case handling capacity. |
These are arithmetic examples, not approved patterns or equipment ratings. They exclude rejected products and production interruptions. If the upstream line delivers only 240 accepted cups per minute, a 12-count case has a theoretical supply limit of 20 cases per minute before additional case-packing losses. A buffer cannot overcome a sustained shortage of products.
At 25 cases per minute, one completed case must leave the agreed output boundary every 2.4 seconds on average. That interval is not necessarily the duration of an individual machine movement or the available adhesive setting time: operations can overlap. Ask the supplier to show how the proposed sequence sustains the requested output.
Submit finished product samples with the actual lid, sleeve, or shrink wrap. Record top and base dimensions, height, taper, weight, surface condition, and dimensional variation. Include the package's resistance to tipping, gripping, and compression, plus acceptable damage limits. An empty rigid container does not reproduce a finished noodle pack during loading.
Draw the arrangement inside the case: rows, columns, layers, upright or inverted orientation, alternating orientation if required, and the total count. Identify dividers, trays, or inserts. Ask the supplier to explain where turning occurs, how the group is held, and how it enters the carton without damaging lids or film.
The product page describes lane separation, cup overturning, accumulation, servo cup/bowl pushing, box filling, and box sealing. It lists cup/bowl shape as customized. Request a SKU-specific sequence and tooling schedule; those descriptions do not establish a universal size range or prove that every packing pattern works.

Send the carton drawing and production samples from the intended supplier. State internal and external dimensions, board grade, flute or other construction, thickness, coating, print, score lines, and tolerances. Include the case contents and total packed weight. Carton dimensions must accommodate the actual arrangement without allowing damaging movement or compressing containers.
Identify whether the machine receives flat blanks, glued flat cases, or another supply form. Ask the supplier to name the supported construction and show how the carton is picked, formed, loaded, and closed. A general description of “carton feeding” is insufficient to decide what blanks the factory should purchase.
Shangbaotai publishes storage for 600 carton pieces. Confirm the usable magazine capacity for the proposed blank and its replenishment method. If one piece makes one case, 600 pieces would cover 24 minutes at 25 cases per minute under ideal continuous consumption. That calculation excludes low-level reserves, unusable blanks, and other interruptions; it is not a guaranteed refill interval.
Trial carton separation and formation with representative samples. Record missed picks, double picks, skew, damaged edges, and incomplete formation. Identify the response to an empty magazine and whether replenishment requires a stop.
Measure accepted products arriving from the preceding process, including lane count, conveyor height, direction, pitch, and flow variation. State whether the incoming cups or bowls are already sealed and wrapped. Define where upstream defects are removed and which machine owns the handoff signal.
For an upstream sealing section, the bowl and cup noodle sealing equipment should be reviewed together with the case-packer infeed. Require agreement on product orientation, transfer points, and stops. A mechanical connection alone does not settle whether accepted product flow supports the case target.
Size accumulation against a defined event. For example, at 300 products per minute, absorbing a 20-second downstream interruption would require room for 100 additional products if upstream production continues and no other losses occur. This is a planning example, not a recommended buffer size. Confirm usable capacity, product stability, and controlled stopping when the buffer fills.
At the case discharge, specify closed-case dimensions, weight, orientation, conveyor height, and downstream accepted capacity. Include labeling, inspection, further conveying, or palletizing only where required, and assign a supplier to each operation. Request stop-and-restart tests across the connected equipment.
The product page refers to a hot-melt adhesive system. Confirm the current manufacturer, model, and supplied configuration in the quotation. Do not infer adhesive compatibility or local spare-parts availability from a brand reference on a website.
Provide the carton bonding surfaces and the approved adhesive specification, if available. Ask the equipment and adhesive suppliers to establish application temperature, bead location and amount, open time, compression, and the condition required before the case moves downstream. Printing or coatings on bonding surfaces must be included in the material trial.
Define closure acceptance: flap alignment, bond coverage, resistance to opening, visible adhesive defects, and package damage. Agree on the sample method and test conditions. Require a response for low adhesive, temperature outside the approved window, blocked application, or a stop during closure. Specify whether detection or alarms are supplied for each condition.
List defects at both product and case level. Product defects may include damaged shrink wrap, a deformed container, or an incorrect incoming pack. Case defects may include wrong count, wrong arrangement, carton damage, or inadequate closure. Mark which checks happen upstream and which belong to the case-packing scope.
The website mentions discharge of undesirable shrink film but does not explain the complete detection and rejection logic. Ask what the system detects, how a flagged product is tracked, and where it is removed. Do not assume that this function also detects missing contents or every glue defect.
Challenge agreed detection functions with representative defect samples during testing. Confirm reject removal, reject-bin management, and the response to a failed reject. Define how partially assembled groups and unfinished cases are handled after a fault, so restart does not release incorrect counts.
Shangbaotai's published utility references are three-phase 380 V/50 Hz and air consumption of 1.5 m³/min; total power is customized. Confirm the project electrical supply, operating and peak air demand, required pressure, and all installation requirements. A published air-flow figure alone cannot size the site's compressed-air connection.

Specify accepted, correctly filled and closed cases at the agreed discharge point over an agreed trial period. State whether the target applies to steady running or includes routine replenishment and short stops. Test every launch SKU with the intended products, cartons, and adhesive. Record output, rejects, stops by cause, count accuracy, container damage, and closure results.
Include changeover, missing products, disrupted infeed, low carton supply, reject challenges, and blocked discharge. Agree on who provides test materials, the quantity required, and the correction and retest procedure. Factory testing should cover the supplied modules; site testing should verify the actual upstream and downstream connections.
No universal SKU rating is established by the public page. It states a maximum reference speed. Require confirmation for the proposed container, carton, count, arrangement, and test conditions.
At 25 cases per minute, the arithmetic requirement is 300 accepted cups per minute. Allowance for rejects and interruptions must be assessed using the project's measured flow and agreed acceptance basis.
No. Twenty-four minutes is an ideal calculation assuming one usable piece per case and continuous consumption at 25 cases per minute. Confirm actual capacity, reserve level, blank behavior, and refill procedure.
Do not assume it is included. Define the incoming pack condition and ask for a supplied-equipment list identifying any wrapper, inspection, accumulation, connecting conveyors, and downstream modules.
Send finished cup or bowl samples, carton samples and drawings, the required packing pattern, measured incoming rate, case-output target, adhesive requirements, and the site layout.
Submit the project data sheet through Shangbaotai's inquiry page. Ask for a confirmed packing pattern, handling sequence, carton and adhesive specifications, utility schedule, interface drawing, reject scope, and sample-test plan. Use that evidence to decide whether the published 25-case reference can support the required accepted output in the factory.
