Pressure-casting plant for cups Type TDG/500
The pressure casting plant for cups, which was developed at LIPPERT under the term TDG/500,
enables discriminating manufacturers of tableware to produce cups with handles in one piece.
By this technology producers obtain interesting possibilities of design. An important aspect
is that shaping of the cup is not limited to axisymmetrical shapes. Designers don't think of
cup bodies and handles, but of cups with handles. Now, the TDG/500 offers the perfect solution
to that creative challenge. Tomorrow's classic designs are today.
LIPPERT pressure-casting machines convince not only aesthetes, but also cool calculators.
As everybody knows, cup handles were the most expensive parts to produce. With the TDG/500
in your production line, that will be a thing of the past
LIPPERT has given substance to the concept of fully automated pressure-casting practice,
including drying and on-line robot finishing.
The pressure-casting plant itself is of simple, compact design, thanks mainly to the use of
servo-controlled axes instead of hydraulics: three axes open and close the mould, and an
additional servomotor handles the slip pump. The multipart dye tooling is made of porous
mould material.
Patents are pending on various details of the machinery. The pressure-cast cups are automatically
demoulded and placed in a solidification dryer. Subsequent automatic finishing is attended to
by six-axis robots and diverse finishing tools.
In actual practice, the use of triple moulds, i.e., moulds with room for three cups, is ideal in
terms of lot size and cost efficiency for standard type cups.
Depending on the cycle time of the slip and the intricacy of the cup's design, the ag-gregate
solution assumes the character of a so-called pressure-casting island. Such an island can comprise,
say, two pressure-casting systems, a common dryer and two fin-ishing robots.
LIPPERT offers holistic tooling setups, including engineering drawings, individual tools and/or
mould components, or all-in tooling, whichever you prefer.
The advantages of LIPPERT cup pressure casting:
- Freedom of design, i.e., nonaxisymmetrical cup bodies are now doable
- High precision even for complicated shapes
- Single-casting cups: Forgotten the difficulties of attaching handles to bodies
- Fully automated pressure-casting process all the way up to firing
