dexter MT develops RRIM

Rolling the rims of plastic cups is a well-known problem. Up to now, an extra production step has been needed to produce the rolled rim. That cost additional time and money.

Our very latest innovation solves a problem that was thought to be unsolvable. Rim Rolling In Mould produces a rolled rim on a cup in one step. We’re immensely proud to have invented a method that enables the rim of the cup to be rolled INSIDE the cup mould.

1. No need to invest in an extra production step – resulting in significant savings.
2. The extra production machine needed for rim rolling takes up a lot of space – this space can now be used for something else.
3. Rims could only be rolled on round products. We can now roll any shapes – even square, triangular or a combination of these.
4. You benefit logistically because the cup is ready straight away – no more intermediate handling required.
5. The mould is operated in the machine so there is no additional equipment to learn.
6. The outer dimensions of the cup are calibrated. Because the closing dimensions are fixed, the cups fit lids of any film thickness.

1. The mould is installed on all standard tilting machines.
2. The machine doesn’t need to be specially adapted.
3. RRIM is available for all shapes including square and rectangular.
4. The rim can be rolled in different styles such as flat or open.
5. RRIM can be used with any materials.
6. Cycle time is the same or marginally shorter because the rims are rolled during the cup moulding process.
7. The cups have fixed, calibrated outside dimensions regardless of the film thickness used.
8. The equipment does not have to be adjusted for different film thicknesses.
9. Cups can also be produced without a rolled rim.
