Bosch Sprang launches an innovative thermoforming tooling system for floating Polypropylene K-cups

Bosch Sprang Tooling SystemBosch Sprang along with its parent company Kiefel, has developed a new thermoforming tooling system for producing Polypropylene coffee cups that can be recycled.

These cups can be easily recycled in water separation tanks as their material density below 1.000kg/m3. And it does not require any additional machine adaptions.

This new patent pending tooling system has been statistically analyzed and tested and can also be adapted to most tilting bed style thermoforming machines.

The technology is based on innovative multifunctional elements in the tool that enable and control the realization of very specific mechanical properties of the coffee cups. To maintain the consistency in the production of cups it is essential to have balanced sheet specification, the process parameters, and tool.

Mechanical properties of the system ensure problem-free usage of the cups in all commercial K-cup coffee systems.

The production line is based on a Kiefel KTR 6.1 Speed, a Bosch Sprang 91 cavity tool, and Mould & Matic downstream equipment. Having its production capacity around 1 billion cups per annum (24/7) this production system represents Kiefel’s ability to provide turnkey solutions.

The KTR 6.1 Speed allows more power and speed which in-turn leads to higher output and new trend products. This allows processing a wider range of materials such as (R) PET, PP, PS, PLA, PE and others, inclusive foamed plastics.
