Raw Materials of Nails

Manufacturers use various metals such as steel, aluminium, copper, brass, bronze, stainless steel, and nickel to produce most nails. Additionally, nail silver, monel, zinc, and iron find common usage in nail manufacturing. Galvanized nail has a zinc coating to enhance their resistance to corrosion. Blued steel nails undergo heat treatment to acquire a pale blue oxide finish, which provides a certain level of corrosion resistance. To enhance their grip, manufacturers apply a plastic resin coating to nail covered with concrete. Certain brands also feature a coloured enamel coating that matches the secured material.

Manufacturing of Nails

Process cycle

We produce most nails by using coils of metal wire. A nail-production machine handles the wire and can produce up to 700 nails. Afterwards, we can further shape, polish, finish, and package the nail.

Framing

We draw the wire from a loop coil and handle it in the nail-production machine, where a pair of grippers dies hold it. The shape of the nail’s head has been machined at the end of the die.

As the dies secure the wire in place, a mechanical hammer strikes the free end of the wire. This twists the finish of the wire into the die cavity to shape the top of the nail.

With the wire actually clipped in the dies, a bunch of molded cutters strike the far edge of the nail, framing the point and releasing the nail from the remainder of the wire falling off the coil.

The dies open and a removal system thumps the nail into an assortment skillet beneath the machine. The free finish of the wire is drawn from the loop and care of the machine. The cycle then, at that point, starts once more.

Additional forming

A Nail with helical twists, serrations, or other surface configurations is fed into other machines that roll, twist, stamp or cut the required forms. This may be a purely mechanical process or may require heating the material before forming.

Finishing

The nail is cleansed in a rotating barrel loaded up with hard caustic soda. This nail separates any oil from the shaping machine and cleans up any little metal pieces, or nipping, that may be sticking to the nail.

Skilled artisans apply a final splendid finish to many nails before packaging them. They achieve this by placing the nails in a rotating drum filled with hot sawdust, delicately cleansing the outer layer. A Nail undergoes a process where they expose to an open fire in an oven to acquire a blued finish. We use a method called hot-dip galvanization for galvanized nail. This method involves immersing the nails in a tank of liquid zinc. Another option is to apply a zinc coating by heating the nail to approximately 300 °C in a sealed container containing a powder comprising zinc dust and zinc oxide. Finally, other coated nails achieve their final finish by either immersion or spraying.

Depending on the resiliency wanted some strength nails may likewise require an extra heat-treating step.
