Reliably and efficiently produced slit-and-folded closures: they combine functionality with cost- effectiveness for modern filling processes.

All-electric performance with maximum precision and outstanding energy efficiency: the ENGEL e-cap was consistently developed to meet the requirements of closure production.

High-efficiency closure cap production at drinktec 2025: ENGEL presents energy-saving e-cap production cell with innovative features

When the international beverage and liquid food industry meets at drinktec in Munich from 15 to 19 September, ENGEL will showcase the automated production of closure caps. At the heart of the fully automated production cell is the all-electric e-cap 380 injection moulding machine with a clamping force of 3,800 kN. The application combines maximum energy efficiency with outstanding process consistency and demonstrates how ENGEL increases cost-effectiveness in closure cap production through perfectly coordinated complete systems.

The closures produced for United Caps comply with a widely used standard in the beverage industry. The notch of the tamper-evident band – also called the guarantee ring – is formed in the mould and then folded inwards on the underside in a subsequent step. When opened for the first time, the ring separates from the cap body, providing a clear indication of whether the product has already been opened.

Production takes place in a 48-cavity mould with a cycle time of four seconds. In the fully automated production cell, which is integrated into the ENGEL CC300 control unit, the 38 mm caps are conveyed via a cooling conveyor with waterfall sorting to the folding station, where the lower edge of the band is bent inwards – ensuring a secure fit on the bottle neck.

Key Benefits:
All-electric and efficient
Robust plasticising for demanding processes
Digital support for process consistency
Consistent cooling, less scrap with the new ENGEL e-flomo one
