LM-F3-90 Automatic Rim Flatting Machine
LM-F3-90 automatic rim flatting machine: cup top diameter 40-115 mm, height up to 136 mm, 80-90 pcs/min, 7.5 kW.
Quick Answer: What Is The LM-F3-90?
The LM-F3-90 is an automatic rim flatting machine that flattens the curled rim of formed cups into a flat top at 80-90 pcs/min. It is powered by 7.5 kW, needs 0.3 m³/min of compressed air, and ships in 30-35 working days. It is built for ice cream, yogurt and sealed-container producers.
The LM-F3-90 flattens the rolled rim of a finished paper cup to produce a flat top cup. Flat rim cups are the format used for premium yoghurt, dessert and ice cream packaging because they take a foil or film lid cleanly.
It handles cup top diameters from 40 mm to 115 mm with cup heights up to 136 mm at 80-90 pcs/min, and uses an independent ultrasonic welding base for the body seam.
What Is An Automatic Rim Flatting Machine?
A automatic rim flatting machine is an automatic finishing unit that sits downstream of a cup or bowl forming machine. It takes already-formed containers and flattens the curled rim of formed cups into a flat top, so the line keeps running at the speed of the forming machine instead of being limited by manual handling.
On the LM-F3-90 the whole cycle is servo-driven and monitored from one panel: an operator loads material, sets the count and the machine runs unattended. That is what turns a forming line into a finished, packable output for ice cream, yogurt and sealed-container producers.
Feature:
- Flat rim finishing – cup top diameter 40-115 mm
- Cup height up to 136 mm – dessert and yoghurt cup sizes
- 80-90 pcs/min – matched to cup forming output
- Independent ultrasonic welding base – strong body seam
- Double cam drive with automatic oiling – stable continuous running
- Compact body – only L1260 x W1080 mm, 1,500 kg
- Gear transmission – accurate rim pressing
Application:
The LM-F3-90 is used by converters supplying:
- Premium yoghurt and dairy brands
- Dessert and mousse packaging
- Ice cream cups with film lids
- High end retail food packaging
Flat rim cups are a niche but high margin product; one rim flatting machine can serve several cup forming lines because it is much faster than the formers.
Machine Parameters:
| Item | Specification |
| Model | LM-F3-90 |
| Cup Size | Cup top diameter 40-115 mm, height up to 136 mm |
| Production Speed | 80-90 pcs/min |
| Power Supply | 380 V / 7.5 kW, 50 Hz |
| Air Consumption | 0.3 m³/min |
| Net Weight | 1,500 kg |
| Dimension | L1260 × W1080 × H1650 mm |
How Does The LM-F3-90 Work?
The LM-F3-90 runs a continuous, fully automatic cycle. One operator loads material and monitors the panel; the stations below run in sequence:
- Cup infeed: Formed cups are fed into the flatting station in single file.
- Rim heating: The curled rim is softened with controlled heat.
- Rim flatting: The rim is pressed flat to give a level sealing surface.
- Cooling and discharge: The flat rim sets and cups are discharged to packing.
Main Machine Features:
- Flat Rim For Film Lidding: a flattened rim gives a full contact surface for foil or film lids, which is what dairy brands require.
- Ultrasonic Welding Base: the body seam is welded independently of the rim operation, so seam strength does not depend on glue.
- Wide Size Range: 40-115 mm cup top diameters cover single serve desserts up to large family cups.
- Compact Footprint: at L1260 x W1080 mm and 1,500 kg it fits next to existing lines without rebuilding the layout.
- 80-90 pcs/min: fast enough to serve several forming machines.
What Can The LM-F3-90 Produce?
| Product | Typical Size | End Use |
| Yoghurt cup | 70-95 mm | Dairy brands |
| Dessert cup | 60-90 mm | Mousse, panna cotta |
| Ice cream cup | 90-115 mm | Ice cream producers |
| Single serve cup | 40-60 mm | Portion packs, hotels |
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 | 5,400 cups |
| Per 10-hour shift | 10 h | 54,000 cups |
| Per day (2 shifts) | 20 h | 108,000 cups |
| Per month (26 days, 2 shifts) | 520 h | 2,808,000 cups |
Figures are calculated at the rated top speed of 80-90 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-F3-90 The Right Machine For Your Factory?
Choose the LM-F3-90 if:
- You produce ice cream, yogurt or sealed containers that need a flat rim for lidding.
- You already run curled-rim cups and want to add flat-rim SKUs on the same line.
Consider a different model if:
- You only sell hot drink cups with a curled rim: this unit has nothing to add.
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.
