Bolt Cutter Manufacturing Process

What is a Bolt Cutter?

A bolt cutter, also known as a bolt cropper, is a tool used to cut bolts, chains, padlocks, rebar, and wire mesh. It often features long handles and small blades, as well as compound hinges to increase leverage and cutting force. A typical bolt cutter produces 20 kilonewtons (4,500 lbf) of cutting force for every 250 newtons (56 lbf) applied to the handles.

12 Steps Bolt Cutter Manufacturing Process

STEP 1
Raw material

Bolt cutters are constructed of steel, an iron-carbon alloy that can be strengthened with additional components such as chromium or vanadium.

STEP 2
Drop Forging

Bolt cutters are heavy-duty tools manufactured using precision equipment and high-quality steel. They are created via a method known as "drop forging," in which the metal is heated and then pushed into a mould, known as a die, by a falling or powered hammer dropped from above.

STEP 3
Trimming
A special-purpose trimming tool is used to eliminate excess material surrounding a forged object; material is then cut to the appropriate form while keeping trimming weight to a minimum.
STEP 4
CNC machining

A jaw is processed in a single clamping device on a CNC machine, ensuring that it is manufactured within the required size and positioning tolerances.

STEP 5
Hardening

The first stage (hardening) involves heating each blade with a gas torch (or a machine) until it glows red. This happens above 480 degrees Celsius (900 degrees Fahrenheit).

STEP 6
Tempering

The second stage (“tempering”) reduces the brittleness of the blade and leaves it more supple and resilient.

STEP 7
Mounting the handle onto the joint and pressing
the handle is firmly mounted onto the joint. The handle is then pressed onto the joint, which ensures that the mounted handle does not come loose under even the greatest strain.

STEP 8
Bending the handle
Bending the handle
the handle is bent to the required functional angle with a special bending device, which provides the user with ergonomic applicability.
 
STEP 9
Coating
Coating
a protective colour is applied using powder coating technology, which gives the product a professional appearance and also serves as surface protection.
 
STEP 10
Mounting the sleeve
Mounting the sleeve
A PVC sleeve is mounted on the handle that gives a user a good and ergonomic grip.
 
STEP 11
Manufacturing screws and nuts
Manufacturing screws and nuts

is carried out using CNC machines, which, in addition to high-quality materials and heat treatment, provide the best bonding between the cutter's separate components.

STEP 12
Assembly
ASSEMBLY

The qualified, talented, and diligent personnel who execute the final assembly assemble the separate pieces, inspect the major features, and transform the Unior cutter into a high-quality product.
