The requirements of the global market are as simple as they are merciless. An optimum quality of the injection moulded part is required, while the cost pressure is continuously increasing. Shortest cycle time and optimum part quality are the main requirements which have to be met by high-quality injection molds. The main focus lies on the optimum temperature control of the mold. A key factor is the thermal conductivity of the materials used for the cavity forming area. The resulting thermal requirements are met by the high-quality copper alloys of Schmelzmetall.
Screw cap mold: Cycle time reduced by 30%:
For this kind of molds there are various possibilities to use HOVADUR® K alloys and compound solutions. Often, the combination of different materials is the best way to achieve the occasionally desired and/or required characteristics. Both materials are bound using a special process that is partially metallurgical and therefore inseparable.
SCHMELZMETALL has now developed into a leader in innovative production of precipitation hardened copper alloys which are melted and casted under vacuum.
HOVADUR® copper alloys CNCS & CCZ, are now also offered as fine-grained spherical powders <20-100μm. In combination with the well adapted heat treatment we offer the highest level of thermal conductivity & mechanical properties for those HOVADUR® copper alloys CNCS & CCZ print powders.
Highest purity, a controlled low oxygen level, tailored for Additive Manufacturing technologies such like Laser Beam Melting, Selective Laser Melting (SLM), Laser Metal Deposition, Laser Cladding or as well for Metal Injection Moulding (MIM).
HOVADUR® powders offering nearly limitless possibilities for designers of plastic injection molds to produce tool inserts, which can be designed with internal cooling channels, being able to reduce the injection cycle as well as increasing the quality of the injected part.
