Production Line
1. The black annealed twist wire is made using Q195 low carbon steel wire. The main process includes a wire drawing, acid washing, annealing, coiling then packing. The wire is most often used in construction, hand crafts, woven wire mesh, express way fencing mesh, packaging products and other daily uses.
2. There are two types of drawing machines used: powder drawing and water drawing
The powder drawing machine is fit for smaller drawing processes (6.5-4.0mm). One powder machine has 4 tanks and 4 molds, with one tank per mold. Each of them features energy using an electromotor. 0.9mm maximum can be “eaten” when the wire crosses the mold. There is also no weight loss during the drawing process.
3. Annealing is done to lower the tensile strength of the wire. The stove is solid and built with bricks, with a cube like structure. Different wire thicknesses requires a different temperature, ranging from 700 to 900°C. The output of the annealing stove reaches a tensile strength of 400-500N.
4. Through a packing coil of 1-800kgs per roll, the wire is expertly packed into a woven bag, paper box or other way as per customer requests.
