Hollow-bottom cups are cups with a bottom that is drawn in at the base. There are different reasons to make cups in this special way.
Many customers appreciate the extremely small radius at the bottom of the cup, especially when the cup is being decorated. The printable area is maximized here, so there is almost no non-printable area at the cup base.
If the cup is used in different air pressure ranges (e.g. in an airplane or in regions with high mountains), the bottom is used to compensate for the internal volume and the bottom itself serves as a membrane. This prevents sealed cups from bulging or even bursting.
Our tilting tools offer you the best prerequisites for your thermoforming process of hollow bottom cups. MT|easy speed ensures high production speeds. Our sandwich technology stands for highly efficient cutting plates and the best cooling. The processing of powder metallurgical steel (PM) ensures a long service life, maximum performance, dimensional stability, dynamics and hardness. The 6-pillar guide allows the tightest tolerances to be used.
However, plug assist also has a significant influence on the thermoforming process. We have the right plug assist for your requirements. Mafox|P ensures that the plug can be changed quickly. The Mafox|2 quick-change system allows you to change the ejector bottom in seconds and with Mafox|F, clamp ring crowns can be optimally matched to the product to be manufactured. You control the pressure of the clamp force thorough the pressure-independent clamp rings in the thermoforming process. With our stacking systems, the formed hollow bottom cups can be reliably stacked in logs.
