Sawing Wire For Solar Wafer Cutting
Sawing wire , also called ultra fine wire,is cold drawing high strengh brass plated steel wire with high carbon.It can be used for cutting high hardness of single crystal line silicon,poly crystal line silicon,quartz material,etc.
Development of the sawing wire
Sawing wire is a high grade steel wire that can be used to cut a wide range of products,such as silicon, germanium, gallium aresenide, quartz, indium phosphide. It serves as the abrasive carrier in a Multi Wire Saw.
Saw wire is mostly used in the production of solar cells. The use of photovoltaic energy is increasing, as humanity becomes more and more aware of the scarcity of the natural resources.
The technique finds its origin in the world of solar cells. From the mid eighties, this technology was developed to decrease kerf loss and increase productivity.
In the early nineties the method was also introduced for slicing silicon ingots to wafers for the electronics industry. Since then the technique has been more and more introduced for cutting other hard and brittle materials as well.
Advantage Of Ultra fine wire
Tight diameter and ovality tolerances.
Very thin and tensile wires of low keff loss.
More wafers per cut and less fractures to make higher productivity.
A wide range of spool types assures it can be used on all machine types.
An advanced winding technology makes delivering an optimal winding quality.
High strength and heavy load, Lower costs, lower weight and higher fuel savings.
An annual output of 10,000 tons of sawing wire for Solar wafer cutting.

Raw Material Of Ultra fine wire
For certain excellent mechanical performance, Hengxing group requires suppliers for customization,especially on tensile and some key elements. In trace element composition of wire rod, we have high expectations for the c, since the c plays a key role for crystal nucleation.
Production Workshop
To ensure extreme precision and excellent performance of steel wire, hengxing group utilizes advanced production and control equipment in the world. Lubricants from France and drawing mold from Sweden to keep lower temperature and enough smoothness for better precision and surface quality. Germany electronic flowing measurement and Siemens temperature adjuster keep lubricant in needed state.
