Heat Treatment
Heat Treatment
There are 3 main factors to decide the quality of beauty shears.
- Material 2. Heat Treatment 3. Craftsmanship
Out of the three, the level of heat treatment technology is hardest to judge by eyes.
First of all, high quality materials are needed to make high quality shears.
Second, proper heat treatment technology is needed in order to make the material have the best characteristics for shears.
Third, it is necessary for shears to be made by highly skilled and experienced craftsman.
As you may know from experience, some shears go dull within a week but some shears are able to stay sharp for 6 months or more. Highly skilled craftsmanship can give the shears nice cutting sensation. However, it is up to the materials and the heat treatment applied that allows the shears to last longer, regardless of the cutting feeling.
Various heat treatments are used for different types of metals and their usages. Different heat treatments can change the hardness and abrasivity even in the same metals. Also, the level of heat treatment skills are different in various countries. Japan, Korea, and Germany are in the top tier when looking only at the level of heat treatment for shears; while China and Pakistan are considered to be 10 to 20 years behind them.
Most of the shear factories in Korea and Japan doesn't have the facilities for heat treatment. As a result, the materials need to be sent to factories specialized in heat treatment. Expensive high-tech equipment are useless without experts to properly handle those machines, so only a few factories in the world have their own heat treatment facilities.
The heat treatment technology for the shears are unique, so it is only available at certain factories in Korea and Japan. However, Japan is a little bit ahead of Korea in the heat treatment technologies. The Japanese superior car manufacturing technology might have influenced the higher level heat treatment technique in the shear industry.
Cheap shears that seems to be high in quality usually do not go through proper heat treatment process or are made with low quality materials. If you buy these shears at a high price, you will most likely have some trouble.
*Vacuum Heat Treating Furnace*
The following introduces commonly used vacuum heat treatments in Korea and Japan.
<Heat Treatment>
- Heat treatments involve the usage of heating or chilling to harden or soften metals.
< Quenching>
- Quenching is a process of heating metals to an extremely high temperature and then cooling them rapidly.
- This makes ferrous metals harder and non-ferrous metals softer.
<Tempering>
- Tempering is a process of reheating metals to high temperature then back to low temperature.
- Tempering makes metals more ductile and tough.
< Subzero treatment >
- Subzero treatment is a process of cooling metals to an extremely low temperature.
- This enhances metal's wear resistance strength and makes the metal harder.
