How Are Padlocks Made?

Padlocks are available in a wide variety of sizes, shapes, and colors. Throughout history, padlocks have been designed in different ways depending on the technology and processes available to different people and civilizations. Nevertheless, the importance of padlocks has remained the same over the years: to provide security and, by extension, a symbol to secure love and signify commitment between lovers or friends.

Today, padlocks are indispensable. We depend on them for security, making preferences in design, size, shape and complexity. However, the real question is: what's inside a padlock? What makes this somewhat mysterious box impossible to open? What is the mechanism behind it? This article will consider padlocks. What is inside? And how they are made.

What is Inside Padlocks?

The inside of padlocks contains a lot of components. The first component is the plug, which is where the key is inserted. It appears to be a cylinder with a slot for a key to pass through. Plugs consist of several components, all of which play a role in opening the lock.

Next are the pins, which are bullet-shaped metal bits above the plug. A lock typically consists of six to twelve pins arranged in pairs. In a stack of pins, the top pin is the driver pin, and the bottom pin is the key pin. There is also an additional pin known as the security pin, which prevents the removal of the plug. For safety reasons, springs secure the pins inside the plug, so they do not slip out.

The next components are the latches, which are held together by two springs behind the plug.

Finally, there is the shackle. The shape is asymmetrical. When the padlock is opened, one side is long enough to reach the bottom, while the other is short enough to draw out when the padlock is opened.

How Padlocks Are Made

Padlocks are created in several factories, and it takes time to make a padlock since it involves different processes.

Making the Body

Stacks of metal sheets are laminated together to make the padlock's body. The stacked metal pieces make the inside of the body stronger, preventing easy lock breaking, while the lamination strengthens the metal. The padlock’s body is completed by riveting caps into the metal after shaping.

Making the Shackle

Machines cut steel rods to fit into holes in the lock body. Then they are tempered and bent by a bending robot. The bottom of the shackle is then split into divots. The divots ensure that the locking mechanism works properly. After everything is completed, latches will eventually catch on holes and stop the lock from opening.

Making the Mechanism

Everything that goes inside padlocks is made here. At this stage, ball bearings are sometimes inserted into padlocks, without which the padlock can be shimmed open.

The inside of a padlock is filled with a cylindrical case to allow a lock cylinder to be inserted. Machines assemble cylinder pieces, which consist of taking a plug, adding pins and springs, and encasing it.

Last Stage

A key is cut to match the pins in the cylinder. Usually, the padlock is tested at the end of the process to ensure everything is working properly. In addition to testing the padlock's ease of use, it is also tested to ensure that it is strong.
