Caps & Closures

 

With the many different sizes and shapes numeric controlled sheet feed is an essential improvement for this industry. Aside the flexibility also the precision of reproducing print images up to the point of matching embossing became an important factor. For the many shapes and types of closures we offer different solutions with impressive features.

TWIST OFF (Lug Caps)
Also in this application our sheet feed presses run full carbide tooling without pillars. Aside our general features our shell presses enable to produce perfect buttons for all sizes using hard button tooling. The unique hydraulic shut height compensation guaranties constant pull down and release values with machines being cold or warm.

HAIRLESS, our patented shell tool system to prevent the generation of angle (laquer) hair plays an important role in providing clean caps especialy with BPA-NI laquers.

Compact and very flexible complete lines are available using our RTC(L) technology which allows to produce caps in lane (caps are kept in same lane from shell tool all the way to the finished cap including lining.

PVC-Lining is integrated in curl and lug-forming press with limited spinning speeds per station which reduces the consumption of compound by about 20% not pushing it up the wall.

The QUICK CHANGE option enables change times within less than 30 min for the complete line.

PVC-FREE LINING
Plasticisers of PVC-compounds  react especialy with oil and fat containing food. TPE (Thermoplastic Elastomere) known long years from crown caps prevent this risk. AH has early up developed a special patented process which allows to line finshed caps with TPE-compounds. The special feature of running fully formed lug caps enables the operation of the liner stand alone and use existing lines for the cap formung without any modification.

The machine is designed to be extremely flexible allowing to line any of the shown caps and closures made from steel or aluminum with QUICK CHANGE between sizes and shapes.

PT Press On Twist Caps

Having been supplying such lines since decades only recently AH managed to successfully test pack such caps with several baby food producers using TPE compound. Industrial introduction is immanent.

PP Pilver Proof Caps

TRIMLESS allows to produce short caps as they are also used typicaly on metal bottles without trim on regular sheet feed presses. This saves not only the hazzle with trim ring separation and but also saves about 5% of metal. For these short caps AH also offers TPE-Lining.

For long redrawn caps AH also offers complete lines with typical capacity of 400, 800 and 1200cpm.
 
A special feature is our ability to provide EMBOSSING right on the sheet feed press matching the print. QUICK CHANGE tooling is available which allows to change embossing shapes in minutes.
