LM-B3-90 Medium Speed Paper Bowl Forming Machine
LM-B3-90 medium speed paper bowl forming machine: small 5-24 oz, standard 16-46 oz, large 28-85 oz, 50-90 pcs/min.
Quick Answer: What Is The LM-B3-90?
The LM-B3-90 is a medium speed paper bowl forming machine that forms paper bowls for noodles, soup and salads at 80-90 pcs/min (small bowls), 75-85 pcs/min (standard bowls) and 50-60 pcs/min (large bowls). It is powered by 380 V at 20.6, 21.6 or 28.4 kW depending on the configuration, needs 0.4 m³/min of compressed air, and ships in 30-35 working days. It is built for instant noodle, soup and ready-meal bowl producers.
The LM-B3-90 is sold in three configurations on the same platform: a small bowl version for 5-24 oz running at 80-90 pcs/min, a standard bowl version for 16-46 oz at 75-85 pcs/min, and a large bowl version for 28-85 oz at 50-60 pcs/min.
You choose the configuration by the bowl range you sell, and the machine is built to that specification rather than being compromised across the whole range.
What Is A Medium Speed Paper Bowl Forming Machine?
A medium speed paper bowl forming machine is an automatic forming machine that turns pre-printed, die-cut paper blanks into finished paper bowls in one continuous cycle: the blank is fed, the body is formed and side-sealed, a bottom disc is inserted and heat-sealed, the rim is curled, and finished pieces are counted and stacked.
Unlike semi-automatic equipment, which moves cups between stations by hand, a fully automatic machine such as the LM-B3-90 keeps every station in mechanical phase. That is why it can hold 80-90 pcs/min (small bowls), 75-85 pcs/min (standard bowls) and 50-60 pcs/min (large bowls) with a single operator, and why output stays consistent across long shifts for instant noodle, soup and ready-meal bowl producers.
Feature:
- Three configurations – small, standard or large bowl
- 5-24 oz small bowls – 80-90 pcs/min
- 16-46 oz standard bowls – 75-85 pcs/min
- 28-85 oz large bowls – 50-60 pcs/min
- Integral mould and robot arm take-out – clean bowl handling
- Gear transmission and Lester heating – proven bowl sealing
Application:
The LM-B3-90 is used for:
- Soup bowls and food containers
- Instant noodle bowls
- Salad and deli bowls
- Large family bowls in the 28-85 oz range
The three configuration approach means a factory that only sells large bowls does not pay for speed it cannot use on small sizes.

How Does The LM-B3-90 Work?
The LM-B3-90 runs a continuous, fully automatic cycle. One operator loads material and monitors the panel; the stations below run in sequence:
- Blank feeding: Pre-printed, die-cut fan-shaped blanks are loaded into the magazine and fed one by one.
- Body forming: The blank wraps around the mandrel and the side seam is sealed with heat.
- Bottom insertion: A bottom disc is punched from the paper roll and placed into the body.
- Bottom sealing: The bottom heater bonds and knurls the base so the container is leak-proof.
- Rim curling: The top rim is rolled outward for a smooth drinking edge and a tight lid fit.
- Counting and stacking: Finished pieces are counted automatically and stacked into sleeves.
Main Machine Features:
- Configuration Not Compromise: each machine is built for one bowl range, so you get the best speed for the size you actually sell.
- Integral Mould: keeps bowl walls straight and round for clean stacking.
- Robot Arm Take-Out: bowls leave the mould mechanically, reducing rim deformation.
- Lester Bottom Heating: bowls hold hot liquid without bottom leakage.
- Same Platform As Cup Machines: shared parts and service knowledge across the medium speed family.
What Can The LM-B3-90 Produce?
| Product | Typical Size | End Use |
| Small soup bowl | 5-24 oz | Takeaway soups, samp |
| Standard food bowl | 16-46 oz | Noodles, ready meals |
| Large family bowl | 28-85 oz | Family packs, catering |
| Salad bowl | 16-46 oz | Deli chains, supermarkets |
Output Planning: What Can You Expect Per Shift?
Use these numbers to size the machine against your order book:
| Production Window | Running Time | Output At Rated Speed |
| Per hour | 60 min | 3,600 bowls |
| Per 10-hour shift | 10 h | 36,000 bowls |
| Per day (2 shifts) | 20 h | 72,000 bowls |
| Per month (26 days, 2 shifts) | 520 h | 1,872,000 bowls |
Figures are calculated at the rated top speed of 80-90 pcs/min (small bowls), 75-85 pcs/min (standard bowls) and 50-60 pcs/min (large bowls) and assume steady material supply and normal changeover time. Running smaller sizes or heavier board will sit at the lower end of the range.
Is The LM-B3-90 The Right Machine For Your Factory?
Choose the LM-B3-90 if:
- You need 80-90 pcs/min (small bowls), 75-85 pcs/min (standard bowls) and 50-60 pcs/min (large bowls) of steady output and want one machine to cover three configurations: small bowls 5-24 oz, standard bowls 16-46 oz and large bowls 28-85 oz.
- You supply instant noodle, soup and ready-meal bowl producers and need consistent, leak-proof quality on every batch.
- You want a medium speed (LM-C3 / LM-B3) platform with mechanical cam drive rather than chain drive, to keep maintenance predictable.
- You plan to run two shifts and need the machine to hold tolerance over years, not weeks.
Consider a different model if:
- Your orders are still small and seasonal: a lower-output model keeps your capital cost down.
- You only need one fixed size today: a dedicated single-size machine is cheaper than a wide size window.
- Your main problem is defect rate rather than speed: add an inspection machine before buying more forming capacity.
Send us your container sizes, board specification and target output per month. Our engineers will size the right model and confirm the tooling before you order.

FAQs:
Which bowl configuration should I choose?
Choose by the bowl sizes you sell: small for 5-24 oz at 80-90 pcs/min, standard for 16-46 oz at 75-85 pcs/min, or large for 28-85 oz at 50-60 pcs/min.
Can one LM-B3-90 make all bowl sizes?
No. Each machine is built in one of three configurations so that it runs at the best speed for that size range, instead of being slow on every size.
What power does the LM-B3-90 need?
Power depends on configuration: 20.6 kW for small bowls, 21.6 kW for standard bowls and 28.4 kW for large bowls, all on 380 V with 0.4 cubic metres per minute of compressed air.
What is the lead time and how is the LM-B3-90 shipped?
Standard lead time is 30 to 35 working days after the deposit. The machine is packed in a fumigated export wooden case with moisture protection, shipped by sea as a full container or groupage, and delivered with a full spare parts kit, tooling set and English manuals.
Do you provide installation, training and after-sales service for the LM-B3-90?
Yes. Every machine is tested with your container size before shipment, and we provide installation guidance, operator training videos and remote commissioning support. Engineers can be dispatched for on-site commissioning, and wearing parts are stocked for long-term supply.
Can the LM-B3-90 be customised for special sizes, board or voltage?
Yes. The tooling set is made for your target size range, and the electrical system can be built for the local voltage and frequency of your country. Optional units such as online inspection, paper blank feeders and embossing can be added at the time of order.
