Conventional production processes
Application Example: HOVADUR® Alloys in Plastic Injection Molding:
Modern injection molds must deliver top-quality molded parts in the shortest possible cycle times. To achieve this, heat introduced by the plastic must dissipate rapidly and evenly. Only with efficient heat distribution can a homogeneous temperature be maintained across the mold surface, preventing hot spots and ensuring part consistency.
Additionally, reducing the temperature from injection to demolding levels as quickly as possible is essential for minimizing cycle time.
This is where the high thermal conductivity of HOVADUR® alloys plays a critical role.
We are happy to advise you on how to fully leverage the advantages of our alloys for your specific application. Don’t hesitate to contact us.

Additive Manufacturing
Modern injection molds must deliver top-quality parts in the shortest possible cycle times. High thermal conductivity in the mold materials plays a crucial role in achieving this. However, in certain applications, thermal conductivity alone may not be sufficient or the HOVADUR® alloy may require localized protection against wear in high-stress areas.
For these challenges, SCHMELZMETALL offers innovative solutions through its advanced hybrid and generative processes, unlocking new possibilities.
Selective Laser Melting (SLM)
The selective laser melting (SLM) is a generative production process which is often called 3-D printing.
The selective laser melting of our HOVADUR® alloys open up completely new possibilities and degrees of freedom to the designer:
- Ideal combination of high thermal conductivity and cooling close to the contour
- Shortest cycle times
- Unlimited contouring freedom

Laser Metal Deposition (LMD)
Laser metal deposition (LMD) is part of cladding. During this procedure, nearly any material can be applied to a part by means of fusing.
HOVADUR® alloys plus laser metal deposition – local wear protection exactly where it is needed:
- Use of our highly thermal conductive HOVADUR® alloys, even for very wear intensive applications
