Technical challenges related to EIM

Silver Flake
Silver flakes have excellent electrical and thermal conductivity properties. This means that their heat dissipation and good electrical efficiency are difficult to compare. They precisely control current and heat in certain products. Although they are more expensive than other fillers, they perform better in difficult electrical applications.

They perform best in components that require conductive fan data adhesives, such as printed circuit board (PCB) components or thermal interface materials, such as heat sinks.

Graphite
Graphite exhibits excellent thermal conductivity and good electrical properties. Its efficiency in dissipating heat and flowing current makes it an ideal material for various applications. Graphite also exhibits exceptional strength and resilience in high-stress situations, especially in high-power electrical applications.

Applications of graphite materials may include electric brushes, connectors, and high power electrical components.

Challenges and Considerations Associated with Electric Injection Molding (EIM)
Electrical injection molding (EIM) presents several technical challenges that manufacturers must overcome to ensure the production of high-quality electrical components.

Complex Geometries : Designing molds with complex shapes can be a significant challenge. Engineering accuracy is an important factor in maintaining tight tolerances for operating electrical components. This increases production time and, therefore, manufacturing costs. The use of advanced CAD (computer-aided design) and CAM (computer-aided manufacturing) software is therefore necessary to streamline the design process prior to production.

Material Behavior: Materials exhibit different flow characteristics during the injection molding process. It is usually as important to conduct thorough material testing before production as it is afterward to gain a better understanding of each material’s properties. Knowing how each material reacts when subjected to different conditions is essential to avoiding defects.

Contamination Control: This tiny, easily overlooked contaminant can affect the overall integrity of the final product . Contamination by oils, dust, or other residues tends to compromise the quality of castings, causing defects and performance degradation. The manufacturing environment must be cleaned and regular maintenance performed.
