Compression heading and capping technology
■ What is it?
Ultralight™ is introducing an innovative shoulder and closure assembly design technology that utilises Aisa’s compression moulding and PTH machinery.
1. Volumetric dosing (B) eliminates dose weight variation of the doughnut (C).
2. The mandrel (F) is pushed down and the pressure is applied.
3. The mandrel lifts up, the shoulder is perfectly moulded and welded with a clean orifice to the sleeve.
4. Next, on the capping machine, the cap is clipped on the tube. As it cools, the shoulder orifice contracts and seals around the cap, guaranteeing a tightness of the clipping.
A. Extruder with axial pressure piston for better material melt and fast color change
B. Volumetric dosing system
C. Doughnut (PE dose)
D. Orifice pin
E. Sleeve
F. Mandrel
G. Cap
■ Advantages
- Using less material can help achieve more sustainable tube packaging.
- Existing PTH production lines can be retrofitted.
- It is possible to introduce new cosmetic tube designs.
- We can establish a new standard for tube closures.
- Realising tooling size parts with short lead times is possible.
■ Available on
- It is available on our Decoplas™ PTH lines and Decoseam™ PTH lines. What’s more, it’s compatible with the latest PTH and CM machines, as well as older-generation PTH head machines.
■ Markets
- Cosmetics.
