A special procedure for the manufacture of shears
JAW
1. Cutting: flat steel is cut into the appropriate shape using a machine; the accuracy of the
cutting ensures the minimum consumption of quality material.
2. Forging:
forging parts are made using drop forging technology. Drop forging allowed diverse
ergonomic product shapes. The appropriate course of the fibres, already present in the
rolled blanks, is maintained using the appropriate forging processes.
3. Trimming:
removing superfluous materials.
4. Heat treatment (quenching and tempering):
the heat treatment with hardening and tempering is intended to improve the structure of
the steel, to provide greater hardness and toughness of the product and other properties
required to overcome the strain that work with such products requires.
JOINT
5. Forging part:
the forging part is made by drop forging - cutting, forging, trimming and calibrating.
6. Cnc working:
the entire working of the jaw is done using CNC machines. Clamping devices on the machines
provide the accuracy required for the quality operation of the cutters.
7. Heat treatment (quenching and tempering):
the heat treatment with hardening and tempering is intended to improve the structure of
the steel, to provide greater hardness and toughness of the product and other properties
required to overcome the strain that work with such products requires.
HANDLE-JOINT ASSEMBLY
8. 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.
9. Bending the handle:
the handle is bent to the required functional angle with a special bending device, which
provides the user with ergonomic applicability.
10. Coating:
a protective colour is applied using powder coating technology, which gives the product a
professional appearance and also serves as surface protection.
11. Mounting the sleeve:
a PVC sleeve is mounted on the handle, which gives the user good grip and helps during the
use of the tool.
12. Manufacturing screws and nuts:
is done using CNC machines, which, besides quality material and heat treatment, ensures the
optimum bonds between the individual elements of the cutter.
13. Assembly:
the trained, skilled and meticulous workers performing the final assembly put together
the individual parts, examine the main characteristics and turn the Unior cutter into a high
quality product.
