LM-B4-120 High Speed Paper Bowl Making Machine
LM-B4-120 high speed paper bowl machine: max diameter 150 mm, max height 139 mm, 110-120 pcs/min, 31 kW, 6,500 kg.
Quick Answer: What Is The LM-B4-120?
The LM-B4-120 is a high speed paper bowl making machine that forms paper bowls for noodles, soup and salads at 110-120 pcs/min. It is powered by 31 kW, needs 0.8 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-B4-120 is the bowl version of our high speed intelligent forming platform. It produces paper bowls up to 150 mm in top diameter and 139 mm high at 110-120 pcs/min, which is the output level instant noodle, soup and salad bowl producers need.
Like the cup machines of the same family it uses an open type double cam drive, continuous automatic spray lubrication, gear transmission, Swiss Lester bottom heating, a one-piece machine base and linear guide rail feeding.
What Is A High Speed Paper Bowl Making Machine?
A high speed paper bowl making 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-B4-120 keeps every station in mechanical phase. That is why it can hold 110-120 pcs/min with a single operator, and why output stays consistent across long shifts for instant noodle, soup and ready-meal bowl producers.
Feature:
- Bowl diameter up to 150 mm – instant noodle and soup bowl sizes
- 110-120 pcs/min – high speed output for big bowl orders
- Open type double cam drive – stable forming at full speed
- Continuous automatic spray lubrication – low wear, low downtime
- Gear transmission – accurate station synchronisation
- Swiss Lester bottom heater – strong bowl bottom sealing
- Linear guide rail feeding – clean blank transfer
Application:
The LM-B4-120 is used by converters supplying the hot food bowl market:
- Instant noodle bowls and cup noodles
- Soup bowls and congee bowls
- Salad bowls and deli bowls
- Food service bowls with PE coated board
Because the machine holds 110-120 pcs/min on a 150 mm bowl, a single line can serve a national food brand contract without a second machine.

| Net Weight | 6,500 kg |
| Dimension | L3450 × W1600 × H1850 mm |
How Does The LM-B4-120 Work?
The LM-B4-120 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:
- Double Cam Drive Sized For Bowls: bowl blanks are much larger than cup blanks; the cam drive keeps forming pressure even across the bigger surface.
- Lester Bottom Heating: wide bowl bottoms get even heat, so hot soup does not seep through the seam.
- Whole Machine Base: absorbs the higher forming force of a 150 mm bowl.
- Continuous Spray Lubrication: keeps gears and cams protected during 24 hour runs.
- Gear Transmission: side seam, bottom and rim stations stay in phase at 120 pcs/min.
What Can The LM-B4-120 Produce?
| Product | Typical Size | End Use |
| Instant noodle bowl | 120-150 mm top diameter | Noodle brands, convenience stores |
| Soup bowl | 110-150 mm top diameter | Takeaway hot food, airlines |
| Salad bowl | 130-150 mm top diameter | Supermarkets, deli chains |
| Snack bowl | 90-120 mm top diameter | Popcorn, dried fruit |
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 | 7,200 bowls |
| Per 10-hour shift | 10 h | 72,000 bowls |
| Per day (2 shifts) | 20 h | 144,000 bowls |
| Per month (26 days, 2 shifts) | 520 h | 3,744,000 bowls |
Figures are calculated at the rated top speed of 110-120 pcs/min 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-B4-120 The Right Machine For Your Factory?
Choose the LM-B4-120 if:
- You need 110-120 pcs/min of steady output and want one machine to cover bowls up to 150 mm in diameter and 139 mm in height.
- You supply instant noodle, soup and ready-meal bowl producers and need consistent, leak-proof quality on every batch.
- You want one high speed line instead of two medium speed machines, so floor space and labour stay at one machine.
- 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.
