Chunk mills for extreme applications

High-performance cutting mills for high throughput

A mould with conformal cooling, additive manufactured out of H11 (1.2343)? Currrently a task where only a few providers can deliver the right solution. /H&B/ is convinced of the benefits of this steel, as well as most oft he mould makers are convinced: wear resistance, thermal stability, heat conductivity and hot hardnes. As one of the first providers in market we now are able to print parts out of H11 (1.2343). Additionally we offer the design of the conformal cooling channels, based on in-depth knowledge of our engineers as well as years of experience in mouldmaking and injection moulding. The impact of conforming cooling on all components, mould, tempering unit and injection moulding process is evaluated through a comprehensive approach.

COMPLETELY DIGITAL AND VIRTUALLY UNLIMITED. 3D-LaserEngraving is effected with the most modern, fully digital technology for maximum performance. This makes possible virtually endless design options for innovative and individual textures. In this process, the engraving is applied directly to the steel surface of the mold with a five-axis fiber laser, working in every dimension. The successive build-up of the topography for the engraving takes place in individual ablation steps, removing layers of varying thicknesses. The number of layers and steps determines the depth and the three-dimensionality of the engraving.

SITRAPLAS offers customized material solutions specifically tailored to the requirements of additive manufacturing. We work with you to develop a technical compound or filament based on various raw materials, whether virgin or recycled, tailored to your specific application profile.

Do you manufacture assembly parts from different polymers - and the entire part is supposed to have a uniform colour? This can be achieved with homogeneously compounded thermoplastics granulates in the customer's desired colour. Assembly parts that consist of different polymers and whose inherent colours differ significantly from each other can be produced in a uniform colour by using solid coloured thermoplastic compounds. By contrast to the process of self-colouring in the injection moulding machine when using masterbatches, even the slightest colour differences may be reliably compensated for when colourants in powder form are compounded into thermoplastics granulates. As a result, the granulates are visually uniformly coloured.
