How are pin clasps made?
Several processes are used to make pins, including forging, machining and stamping. The method used depends mainly on the type of pen and the application. However, regardless of the method, the manufacturer must guarantee quality and finish. Before reaching the market, they undergo rigorous testing and controls.
CNC processing
The CNC machining process creates the desired pen shape by removing material from a metal block. Editing is best suited to smaller pens where detail and precision are required. Materials used in machining include steel, aluminum or brass.
After the material is selected, it is placed in a CNC machine that cuts the material from the metal until the desired pin shape is obtained. Cutting time depends on the complexity of the design. After processing, the pen undergoes testing to ensure accuracy.
Stamp
The embossing process is suitable for larger pens, which can be produced more quickly and in large quantities. A sheet of metal is pressed into an already created shape that is shaped like a pen.
During the punching process, the die, which is shaped like the desired pin, is placed in a punching machine and a metal sheet is placed on top. Pressure is applied to the sheet metal, which penetrates the die to form the pins. You can repeat the process as many times as you want and then check for imperfections.
Forge
Forging involves heating a metal rod and then forming it into the desired shape. Therefore, this method is perfect for larger pens where durability and strength are required.
First select the material for the pen. It can be steel or titanium. Then heat it to the desired temperature before placing it in a forging press. Apply pressure to give the stick the desired shape and let it cool until it solidifies.
Common Materials for Making Pins
Like rivets and other fasteners, stud fasteners come in a variety of shapes and materials. The material used in its manufacture determines its use and specific purpose. Here are common pen materials.
- Brass: This material makes the pen resistant to corrosion and improves its aesthetic properties.
- Aluminum: Aluminum is perfect for lightweight pens because the material is not heavy. It also gives the pen the property of corrosion resistance.
- Steel: Steel material represents strength and durability; therefore, steel pins are robust and very reliable. They can be used in almost all industries.
- Titanium: This material is perfect for making machine pins used in heavy industry or machinery industries where high performance pins are required. This is due to its durability, lightness and resistance.
