Spheroidizing Annealing is one of Basic Ways of improving structure of steel and performance, the main purpose of Spheroidizing Annealing is the carbide spheroidization that makes in the microtexture of ferrous materials, reduces the hardness of material, improves the plasticity of material, reduce the resistance to deformation of material, make material be easy to plastic working and be shaped.Will obtain ideal performance and tissue in the screw wire production, key is to select suitable carbide annealing process.
Pickling
Pickling is to remove impurities and scale from the metal surface, which not only enhances the smoothness of the metal surface, but also provides better adhesion for subsequent coatings. For metals used in electrical applications, pickling removes oxide and corrosion layers to restore the metal's conductivity.
Wire drawing is a metal processing process that is mainly used to reduce the cross-section of the wire by pulling it through one or more dies to achieve a diameter that matches the customer's customized product.
Cold Forging
This step works by squeezing the metal between the punch and die until the material conforms to the contours of the die. Cold forging techniques include rolling, pressing, drawing, spinning, upsetting and extrusion. Of course, Jinrui also has hot forging machinery, and the specific operation can be based on the customer's customized needs to select the appropriate production method.
According to the customer's needs, our engineers will prepare the corresponding thread mold to produce the thread size that meets the customer's needs.
Heat Treatment
The heat treatment process alters the internal structure of the metal by heating to a certain temperature and then being cooled in a certain manner to obtain the desired degree of physical and mechanical properties such as hardness, brittleness and softness.
We will do surface treatment for our customers' products according to their needs. A good surface treatment will greatly extend the service life of the bolts. We currently can provide hot-dip galvanizing, electro-galvanizing, oxidation blackening, Dacromet, and Teflon and other surface treatments.
Packing/stocking
We can provide the necessary packaging methods according to customer needs.
We can provide the necessary transportation methods according to customer needs.
