DC828 - high speed rotary trimmer for round lost domes

High speed rotary trimmer – spin dome trimmer


Due to the rising speeds in today’s market and the transition from HDPE to PET, the need for adapted machinery is eminent.
We are presenting a range of rotary trimmers, following the market’s needs:

  • High speed HDPE trimming, often behind rotary wheels
  • High speed PET trimming, often used in the creating of wide mouth jars, as this market is increasing, replacing glass jars


The machine

The DC828 is a high speed rotary trimmer: a spin dome trimmer for bottles with a round lost dome.
The bottles run into the machine and are fed into the star wheel. Then, the bottles are grabbed by the lost dome and run over a curved knife.
In this way, the bottle is trimmed off from the lost dome, and the lost dome gets disposed through a scrap ejection tunnel.

Moreover, the rotary trimmer has a scroll infeed, feeding the bottle seamlessly into the star wheel.

Furthermore, an integrated camera inspection is optionally available, checking the integrity of the neck trim. In case of defect, the bottle is rejected from the trimmer.

The DC828 rotary trimmer can trim heads with a neck diameter up to 80 mm, depending on the design and material distribution.
Although the machine is suitable for round lost heads only, the bottle body can be oval, square, etc.
Most importantly, spin trimming is not about the machine, but about the lost head design. In other words, getting the right quality and scrap free production is strongly depending on the design of the lost dome.
