dexter MT launches Rim Rolling In Mould (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.

There are many reasons why RRIM is more convenient and more cost-effective:

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

How does RRIM work?

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