High pressure casting & Casting

High pressure casting

The automatic high pressure casting production, including drying and subsequent robot finishing, is designed in a simple and compact manner. This is mainly the result of using servo-controlled axes instead of hydraulics: 3 axes control the opening and closing of the mold, and another servo motor operates the slip pump. The multi-part molds are made of porous mold material. The high pressure-cast cups are automatically removed from the mold and placed in a solidifying dryer. The subsequent fully automatic cleaning is performed by a 6-axis robot using various cleaning tools. Various machine details have been registered as a patent.

The advantages

  • Freely designable molds; i.e. non-rotationally symmetrical design of cup body
  • High precision even with complicated molds
  • Cups made from a single piece of material: the usual problems of how to connect the handle to the body are eliminated
  • Fully automated solution from pressure casting to firing

Handle pressure casting

LIPPERT’s handle pressure casting method offers crucial competitive advantages regarding manufacturing costs, efficiency and flexibility. This sophisticated concept for manufacturing up to 600 ready-to-use handles per hour without manual handle seam finishing contributes to a considerable increase in productivity in cup production.

The advantages

  • Fully automated handle manufacturing from the first to the last step
  • Indirect gripping of the freshly cast handles, no softening of the handle by dissolving water during demolding, which means zero indentations on the handle surface
  • Integrated pre-drying to solidify the handles while still soft
  • Automatic finishing of the casting seam -> no “outgrowth” of the casting seam during firing (ceramic memory). Precisely machined geometry of the handle joining surfaces, perfectly adapted to every cup diameter by automatic contour cutting
  • Simply changing the cutting blade allows you to fit the same handle to a variety of different cup bodies. No need for a new set of molds.
  • Fully automated storage on easy-to-handle batts -> zero product deformation

Casting

„Better – more flexible – more efficient“ – with this objective LIPPERT develops, designs and implements slip casting machines for the ceramic industry for more than four decades. A wide program of machines for hollow and core casting was developed in permanent and close cooperation with ceramics producers in the tableware and technical ceramics sector. The high amount of worldwide delivered machines and the excellent references prove the success of LIPPERT slip casting machines.
