Consumer Electronics and 5G Communications

The reason that aluminum extrusions are becoming more prevalent in electrical and electronic appliances is aluminum's properties of low density, light weight, excellent surface treatability, low cost and multi variety of types which can satisfy individual production demands. RH Group offers aluminum extrusions which can be used for computer heat sink, access control & time attendance device, TV frame, speaker enclosure, etc.

Features of Extruded Aluminum Heat Sink
  • Light weight for easy installation and transportation; At the same performance of heat dissipation, the weight of aluminum heat sink is only one eleventh of the cast iron heat sink, one sixth of the steel heat sink and one third of the copper heat sink;
  • Aluminum extensions can be made into various shapes and specifications; Due to the large and uniform cross section of extruded aluminum heat sink, the process of assembly and surface treatment can be carried out in one pass while allowing for direct on-site installation, thus greatly lowering the cost for installation and maintenance; In addition to the high durability, extruded aluminum heat sink is processable with various surface treatments to meet specific application needs;
  • A heat sink made from extruded aluminum can withstand high pressure; Even it is designed with very thin fins, the extruded aluminum heat sink can also withstand loads of pressure, bending, pulling and impaction, avoiding from damaging during transportation, installation and usage;
Examples of Aluminum Extrusions
  • Aluminum extrusion for 5G network equipment
  • Power bank enclosure
  • Aluminum computer case
  • Attendance device frame
  • Cross cut heat sinks
  • Aluminum mobile phone housing
  • Sunflower heat sink
  • GPU cooling heat sink
  • Aluminum decorative faceplate
