The moulds mounted on SMI stretch blow-molders, manufactured using a special aluminium alloy, are a “home-made” product. In fact, SMI relies on a special laboratory for the production of moulds and mechanical components, equipped with an FMS line consisting of 12 CNC machining centres: highly automated machines, running 7 days a week round the clock, even operator-less, according to pre-set production programmes (CAM).
The 12 machining centres are equipped with linear motors with a speed rate up to 80 meters per minute and mandrels achieving a speed rate of 30.000 rounds per minute.
SMI rotary stretch-blow moulder can be equipped with special moulds to produce label-less PET and rPET containers. This eco-friendly solution eliminates the need for glue and additional paper or plastic materials, simplifying the recycling process and ensuring higher purity in recycled PET.
Advantages for the environment and the consumer:
- eco-sustainable solution, as the PET bottle is 100% recyclable
- better compliance with environmental regulations regarding recycling
- easier material recycling, since there’s no label to remove
- no glue needed for label application
Advantages for the bottler:
- saving on the purchasing costs of raw materials (label and glue)
- saving on storage costs of raw materials
- simplified and optimized production process, as no labeller is required for the application of the label.
