UPCAST ® Rod
The principle of the UPCAST® process is to cast molten copper continuously through a vertical die. The lower end of the die reaches into the melt, while the metal in the upper end is solidifying inside the die and the solidified product is pulled upwards through the die by the set of pinch rolls of the withdrawal machine. At Ta Win, we produce Oxygen Free High Thermal Conductivity Copper Rod (OFHC) via direct conversion of LME Grade “A” copper cathodes. Our UPCAST® Plant casts the copper under carefully controlled conditions to prevent contamination of the pure oxygen free copper rod during the process. This method of production results in the highest grade of copper content of 99.99%. With a negligibly small content of extraneous elements, the inherent properties of copper are brought forth to an optimal degree.
The important characteristics of our high-grade copper are:
– Oxygen free
– Low Impurity Level
– Immunity to hydrogen embrittlement
– Excellent fatigue strength
– Excellent impact and flow
– Excellent workability
OFHC Copper is mainly used in plasma deposition, including the manufacture of semi-conductors and superconductor components, as well as high vacuum devices such as particle accelerators.
Wire Drawing
Wire drawing is the process used to reduce the diameter (size) of the rod or wire by repeatedly pulling it through a series of drawing dies.
The wire can be annealed to enhance and maximize ductility and conductivity or can be produced in hard drawn condition. There are many applications for wire drawing, including electrical wiring, cables, tension-loaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments.
Vertical & Horizontal Enameling Process
Enameling is the process of coating the wire with a very thin layer of insulation. The insulation is typically made of tough polymer film materials. During the process, the wire is annealed and charged with enamel through the enameling dies. The dies are cured into the wire by using heat, resulting in electrical insulation. It is used in the construction of transformers, inductors, motors, speakers, hard disk head actuators, electromagnets, and other applications that require tight coils of insulated wire.
Electron-Beam Processing
Electron-beam processing or electron irradiation is an innovative process that involves environmentally friendly – clean and safe – irradiation treatment of wire and cable products using a high-energy electron-beam accelerator to improve mechanical (wear and tear surface resistance), thermal (temperature, aging and impact resistance) and chemical (stress crack resistance) properties of polymers.
The technology crosslinks (by modifying the jacketing structure and component of) cable and wire products with high energy electron beam 1.0MeV to 3.0MeV and thereby increases its melting temperature from typical 110°C to 300°C and lengthens its lifespan from typical few years to more than 25 years.
