Modern product development demands speed and flexibility. Castfast sets new standards in rapid prototyping casting<\/strong> through the consistent use of 3D sand printing. Instead of relying on physical molding equipment, we create your casting molds – including the most complex cores – directly from your CAD data. <\/p>

This process significantly optimizes the time-to-market in the field of rapid prototyping casting. By building the molds using the layering process, we can complete projects in around two weeks, whereas conventional processes often take months. You gain valuable time for the validation and optimization of your assemblies without compromising on quality. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

A decisive advantage of Castfast is the material match between the prototype and the later series part. While other additive processes often rely on substitute materials, with rapid prototyping casting<\/strong> you get real metal from us. <\/p>

Choose from over 200 alloys to test the exact mechanical properties of your design under real conditions. Whether high-strength ductile iron (EN-GJS)<\/strong> for dynamic loads, thermally resilient grey cast iron (EN-GJL)<\/strong> or specialized steel and aluminium alloys<\/strong> – you will receive a microstructure that corresponds exactly to the later series quality. Each component benefits from professional casting simulation, which ensures optimum solidification and microstructure formation during rapid prototyping casting. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Using 3D sand printing (binder jetting), the molds are created directly from the digital design data. This enables immediate production without preparation times for physical mold making.

Yes, because the actual casting process is carried out with the same melts and under the same thermal conditions as in series production, the physical properties such as tensile strength, hardness and elongation are identical to the subsequent series product.
