With rising demands for higher part quality, the need for effective process monitoring is increasing. For precise quality monitoring and process control, temperature sensors must be placed at critical points. However, practical constraints like limited accessibility and space due to cooling channels or ejectors often force compromises. This can result in reduced process insights, even with advanced measurement technology. voestalpine Sensorized Inserts overcome these limitations by enabling the seamless integration of internal channels for sensor placement via additive manufacturing. Using our integration know-how, small diameter channels can be realised with precise positioning up to 0.5 mm from the cavity. This approach allows precise process monitoring at critical areas without sacrificing cooling performance. Utilizing the design freedom of additive manufacturing, sensors can be optimally positioned between cooling channels and the cavity wall, eliminating the need for additional drilling efforts. Moreover, conventional thermocouples offer a cost-effective alternative, as they can be installed directly into the mold insert.

Proper venting in injection molds is crucial for releasing trapped air and gases. This ensures optimal material flow, uniform cavity filling, and high-quality parts. Inadequate venting can lead to defects such as short shots, burn marks, voids, and weak weld lines, compromising part integrity and appearance. By leveraging the possibilities of additive manufacturing, voestalpine solves these challenges with porous, corrosion-resistant tool steels for injection mold inserts. Microscopic pores allow gases to escape directly through the mold surface without affecting structural strength. The standard component voestalpine Venting Inserts are compact porous plugs, which are easy to integrate into molds, boosting productivity, reducing waste, and ensuring superior part quality. Download datasheet for installation guidelines.

Using additive manufacturing, venting structures with a microscopic porosity can be produced that allow a targeted release of compressed air and ensure that the mold remains air free during injection.
