Polycarbonate (PC) is an amorphous, crystal clear engineering thermoplastic which has many attractive mechanical and optical properties. For example, it has very high impact toughness and exceptional high light transmittance as well as good dimensional stability, creep resistance and elasticity over a wide temperature range. Because of its higher price relative to PVC, PE, and PP film, it is generally considered a specialty film.

PET sheet (polyethylene terephthalate) is a common thermoplastic that provides high dimensional stability, excellent mechanical strength and good resistance to creep. It offers resistance to chemicals, provides very low moisture absorption and is a good electrical insulator. PET film sheet also performs well in wear applications and has a tough, hard surface that can be easily machined and polished.

Wire Drawing Dies are one of the most important technical issues in the drawing process. The proper choice of drawing dies and lubricants is very effective in the final quality product. We will focus on types of wire drawing dies.
The wire drawing process reduces the size of a ferrous or non-ferrous rod down to a variety of finished sizes including super fine wire. http://www.natust.com/drawing-....die/wire-drawing-die
Control valves are control devices that are used to manage and control fluid flow, pressure, temperature, or liquid level by varying the flow passage size. In process systems of production wells, oil and gas plants, Chemical and Petrochemical industries, refineries, and power plants, Control valves are frequently used to control or manage any of the process parameters.
