Turning is a form of machining, a material removal process, which is used to create rotational parts by cutting away unwanted material. The turning process requires a turning machine or lathe, workpiece, fixture, and cutting tool. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached to the turning machine, and allowed to rotate at high speeds. The cutter is typically a single-point cutting tool that is also secured in the machine, although some operations make use of multi-point tools. The cutting tool feeds into the rotating workpiece and cuts away material in the form of small chips to create the desired shape.

Hot Forging: It is the process of forming the shape of the metal in hot condition into a predetermined shape. 
A metal is heated to the proper temperature by high-speed electric induction before it is inserted into a metal piece. 
Bolts are hot forged when the material is too large in diameter or it is not malleable enough.

The process of turning sheets of metal into a useful part or component is called sheet metal stamping. The metal is fed into a press, where the stamping tool, also known as a die, creates the desired shape. The die is pressed into or through the metal with tremendous force. The force used in the process is measured in tons.Except for some specialized processes, sheet metal stamping doesn’t use heat. Instead, it is done with a cold-forming technique. Even though no heat is used, the part can come out hot because of the friction that’s created between the metal and the die from the force of the press.

JM Hardware® Screw manufacturing process
First, deliver the entire bundle of steel wires (plate element) to the factory, and then pickling
Insert the wires into the machine. Cut them and then use molds “extrusion.
Depending on the products to determine whether combined with washers, if it is not. Then deliver directly send “tapping.”
The use of different kinds of drill bits (top). The screw twist drill pattern.
Because the twist drill screw process requires constant lubrication with oil spray, then it will be covered with oil for screw do “de-oiled.”
In order to increase the strength and compressive strength of the screws, the screws will be sent to do the heat treatment.
In order to prevent corrosion and increase the beauty, we sent to sandblasting or screw plating, black handle.
Finally, after each inspection, we confirmed screws with no problem. It can be packaged shipped.

When standard fasteners fail under the twin pressures of mechanical stress and aggressive environments, the search for a robust solution begins. JM Hardware® answers this call with our latest production run of custom carriage bolts made from Duplex Stainless Steel D6-70 (2205), a product engineered to deliver unmatched value and performance where it matters most.
