Mould making without a pattern

DIREKT FORM's technology chain offers the most economical solution for producing large or complex castings. Using milling machines that directly machine the mould material, there is no need for a physical pattern.

Direkt Forming

DIREKT FORMING is a technology based on patternless mould making. The casting mould is first modelled virtually and optimized on the basis of the 3D CAD dataset of the casting. Next, the virtual moulds ready for casting are broken down into segments ready for machining. The designed castings are converted by a programmer in CAM programs and then directly machined, close to the final contour, out of blocks of typical mould material using CNC milling machines designed specifically for DIREKT FORM.

The technology for complex castings

Instead of making a mould around a pattern, the mould, core and cavities are machined out of the mould material. This means highly complex geometries, even undercuts, can be made with ease. That avoids the specific problems involved in removing a pattern from the mould. There is no need for draft. Complex contours are produced without additional divisions. The number of cores in the hollow spaces is significantly reduced. DIREKT FORMING therefore makes it significantly easier to produce moulds even for complex castings.

The technology for large castings

By breaking the casting mould into individual segments and assembling the parts before casting, there is practically no limit to the size of the cast mould and thus the casting. DIREKT FORMING considerably reduces the manufacturing effort and costs of large casting moulds compared to wood or plastic pattern making. There is no physical pattern used, saving you considerable amounts of production time.

Easy assembly of the mould

Once the mould has been machined out of the block, casting tubes, chill blocks and other accessories are introduced as needed for the casting. Even large, core-intensive moulds can be fitted together precisely thanks to mould segments machined close to the final contour. This reduces both the effort of assembly as well as subsequent machine finishing of the casting, which accordingly also shortens the time to delivery.
