High-pressure slip casting system for mass production of cups with handles

This high-pressure slip casting machine has been specially developed for the series production of cups, including handles, in a single production step. A specialised innovation team, consisting of experts from the fields of ceramics, technology, design and production, has designed the machine to further develop an already very successful die casting machine. This new development combines efficient functions with an extraordinarily high production output and thus enables the efficient series production of cups using the die-casting process.

Advantages:

One-step production of cups with handles
Significantly increased production quantities
Ideal for series production with infrequent item changes and high output
Cost-efficient production
Low space requirement due to compact design
Wide range of design options for articles
Automatic fettling of the die-cast seams
Supported by an experienced team of experts

Automated die casting production

The die casting process is characterised by an automated process that includes drying and subsequent robot-assisted finishing. This system is characterised by a simple and compact design, which is achieved primarily through the use of servo-controlled axes instead of conventional hydraulics. Three of these axes are responsible for opening and closing the mould, while a further servo motor controls the slurry pump. The moulds, made of multi-part porous material, enable efficient shaping. The finished cups are automatically removed from the mould and placed in a dryer for solidification. The subsequent cleaning process is carried out by a 6-axis robot that uses various cleaning tools.

Advantages:

Freedom of design enables non-rotationally symmetrical designs of the cup body.
High precision is guaranteed even with complex shapes.
The cups are manufactured from a single mould, which eliminates typical joining problems between the handle and body.
A fully automated solution that covers the entire process from die-casting to firing.

Gravity die casting

The pressure die casting process offers significant competitive advantages in terms of manufacturing costs, efficiency and flexibility.

Advantages:

Fully automated handle production process: The entire process from moulding to completion of the handle is automatic.
Indirect gripping of the freshly moulded handles: This prevents the handle from softening due to dissolving water during the demoulding process and thus leaving marks on the handle surface.
Integrated pre-drying: This measure solidifies the soft handles directly after moulding, which makes them easier to handle and ensures quality.
Automatic plastering of the moulding seam: This prevents the moulding seam from growing out during the firing process, which affects the ceramic memory of the handles. The geometry of the handle hinge surfaces is precisely adapted to the cup diameter by automatic contour cutting.
Modular adaptability of the handles: By simply changing the cutting blade, the same handles can be adapted to different cup bodies without the need for a new set of moulds.
Fully automatic depositing on plates: This makes handling easier and avoids handle deformation.
