Casting

In casting, the casting compound is poured under vacuum, atmosphere or stepwise in a sequence of both by means of a mixing and dosing head directly into a workpiece or into a mostly open mold. The material then gels and then hardens, usually under temperature.

Mixing and dosing heads can also be designed as multiple heads, allowing the simultaneous casting of several components. In these multiple mixing and dosing heads, each casting valve is preceded by an electronically driven plunger, which ensures that the exact casting quantity for each component is delivered.

The amount of material to be cast per component varies between a few milligrams, e.g. for components for micro-electronics, and several hundred kilograms, e.g. for MRI coils. In addition, the quantities to be produced and thus the capacities to be maintained vary. We take this variety into account with our various mixing and dosing systems of the micro, compact and epsilon series.

In addition to the mixing and dosing system, complete casting systems primarily include casting chambers for vacuum casting as well as oven systems for the preheating of workpieces or mould tools and for the gelling and curing of the cast parts.

In circulation casting lines, all process steps from mold handling to curing are integrated and automated in one system. These systems are mostly used in large series production.
