Highly polished cores for injection molding

Tool and mold making TruPrint 5000 Tool steel 500 °C preheating

Printed results for highly polished cores made out of H11 using the 500 °C preheating option are crack-free with densities in excess of 99.9%. The polishing properties are also high with no difference to conventional production. Cooling performance is comparable to copper. However, integrated conformal cooling channels have enabled stable plastic parts production in injection molding. Plastic handles produced for an operating room light are able to be produced with a significantly reduced cycle time.

TruPrint 5000

The highly productive, semi-automated 3D printing system TruPrint 5000 prepares you for industrial batch production –  with features such as optional 500 °C preheating and the full-field multilaser equipment with three 500 watt TRUMPF lasers.  Thanks to the preform option, the TruPrint 5000 supports hybrid component production. For this purpose, the component structures to be additively manufactured are applied to a blank.
