Process Of Making Tin Bar Billets For Extruding Lead-Free Solder Wire !

How To Make Lead-Free Solder Wire !

1. Raw material stock, ingredients, tin, lead/copper, rosin, antioxidant testing !

2. The melting of the tin material, the main and auxiliary materials according to a certain proportion of debugging into the melting furnace, after melting with anti-oxidant covered in its surface, this is to prevent the tin material of the tin dioxide (chemical formula SnO2, white, square shape,) to increase the temperature slightly stirring to make it completely dissolved !

3. The casting of the tin material, the heating oil in the fusion process, electric heating, there are also manufacturers using coal heating, the use of oil, electric heating has the corresponding special heating furnace, can actively stir the temperature in real time active control, eliminate the human factors caused by the bad fusion, the melted tin material into the mold, cast into a rod.

4. Extrusion wire, in the entire soldering wire manufacturing process, the extrusion of tin material is the most critical, if there are defects and hidden dangers during extrusion will lead to irreparable defects of soldering wire, it is difficult to find problems occasionally, in order to ensure the production of high quality tin wire, the extrusion to carry out precise control, with very heavy rod objects in the hydraulic press and extrusion mold extrusion of soldering wire, In the extrusion process should pay attention to broken wire, according to the production requirements can be made round wire, flat wire and thick wire, the thickness of the formulation can use another mold !

5. Winding, control winding smooth in the automatic control can count the number of turns, winding will appear uneven, uneven and other bad situations, in the production to carefully solve these problems !

6. Solder wire inspection, packaging and inspection into the finished product warehouse !
