The first is the coil unit. According to the requirements in real life, the special screw factory needs to find out the factory coil, specification, material and product name, as well as the weight and quantity, and then purchase some suitable wire rods. When buying, you should pay attention not to choose low-quality ones for cheap, but for the sake of life, it is better for everyone to choose high-quality ones.
Stainless Steel Screw
The second is annealing, which can increase the forging ability of screws, so that the production of post-processing will be more convenient.
The third is pickling. Although the link is relatively simple, it is enough to deal with the surface of the screw, but this link will make the next link more convenient.
The fourth is to draw the thread to undertake the pickling process above.
Fifth, the beginning, this link is to complete the shaping of the teeth.
Sixth, heat treatment is performed to change the mechanical properties of the screw.
Seventh, electroplating, in order to meet the requirements of customers and the beauty of the product, this link is very important.
With their high corrosion resistance, sturdy construction, and sleek appearance, stainless steel screws have become a staple fastener across industries. But how are these tiny metal marvels actually made? The manufacturing process requires advanced technology and meticulous craftsmanship to produce screws that can withstand immense stress and environmental exposure.
It starts with raw stainless steel wire rod that is cut to length depending on the desired screw size. The rods are then cold forged using powerful presses to form the hexagonal or slotted head shape. Cold forging strengthens the steel through compressive force rather than heat. The heads may also be hot forged for soft steel types.
The pointing and threading comes next using thread rolling mills. The screws are fed between polished steel dies which impress the sharp tip and spiral ridges onto the shaft through tremendous localized pressure. This churns and strengthens the steel grain structure. The screws may be heat treated afterward to further boost hardness.
The screws are then tumbled in barrels to polish and deburr any rough edges. They are washed to remove metal chips and oils before heading to quality control. Advanced imaging systems carefully inspect the screws for defects in shape, size, finish, and integrity down to 40x magnification. Random samples are load tested to specified limits.
The rigorously examined screws are finally packaged and shipped to customers. While simple in appearance, stainless steel screws are the product of immensely complex machining processes and technology. Their success hinges on quality control and precision engineering to guarantee flawless function for years to come. The hidden efforts behind their making reflects why stainless steel screws have become trusted fasteners around the globe.
