In 1986, with the establishment of Boo Sung Engineering Co., Ltd., we started manufacturing various hand saws with firm committment to the enhancement of technology and accumulation of know-how. In May, 1993, the company changed its name to Jerim Metal Engineering and started exporting to various countries such as the U.S., Europe and Australia, advancing

into the worlds saw market in earnest.   Currently, we manufacture and export pruning saws, curved saws and pole tree saws and is equipped with an annual production capacity of 100,000 units.

  Our company boasts of production capacity that matches world-class companies. In addition, ceaseless R&D efforts with the help of various institutions such as Korea Institute of Design Promotion have resulted in a wide array of designs for saw handles

that can satisfy the needs of customers around the world. This has enabled us to have the competitiveness required for the new ‘era of design competition’, moving away from the past era of quality and price competition. Our ergonomic design that promotes the safety and convenience of users has enabled us to register eight utility models and ten designs.

  **  Impulse Hardening Machine for saw blade

# Characteristics of Impulse Hardening


  Improving the resistance of saw blade by impulse hardening the surface of the edge of saw blade in a short period of time.


 As a result of impulse hardening, the hardness of saw blade will be increased from H.R.C 50 to H.R.C.  76, a hardness that can last for at least three times longer.

  **  CNC Automatic Grinder for Saw Blade

  The conventional semi-automatic grinders were inconvenient because each saw blade had to be taken out and a new one had to be fed into the machine manually. However, this machine automatically takes care of this process, which does not only lead to productivity gains, but also grinding around the clock, leading to a reduction in labor cost and material cost. In short, you can catch three birds with one stone!

   # Characteristics of the machine
       The Impuls-H2000 Machine we have is the latest model by IMPULS, a German company. Rather than using the natural cooling mode, the machine improves weak-resistance by using a quick hardening machine at -20° to achieve a hardening of HV 1000~1050.

  **  Automatic Saw Blade Coating Machine

  In the past, we manually painted oil on saw blades to prevent the saw from gathering rust. However, such a method decreases work efficiency and productivity. Accordingly, we have designed and manufactured an automatic saw blade coating machine to reduce the two-stage manual process of cleansing the saw blade and paining oil to one automatic coating. This has enabled us to increase work efficiency and more importantly, prevent the saw from going rusty.
