The metal powder injection-moulding technique has been introduced to raise and increase the quality and quantity of products in the DPRK.
It is a technique to mass-produce at lower costs the goods that are small in size and complex in shape.
Kim Jong Gon, PhD and director of the composite material research institute of the material science and technology faculty at Kim Chaek University of Technology, was instrumental in introducing the technique.
His development is said to be on the world level.
Over ten years ago, the powder material department was assigned the task of establishing a metal powder injection-moulding process at a factory.
Kim Jong Gon was head of the department at the time and he was unfamiliar with that field at the time.
But he buckled down to it with other lecturers of his department.
They established a powder goods production line consisting of a metal powder production process based on gas spraying, hot-mix, injection-moulding, etc. and developed a technique for producing goods.
Those who have introduced the technique say that its introduction has enabled them to radically boost the output of small products with complex shape and reduce their per-unit cost to one third as compared to previously.
Kim also developed the lever of the assembling tool of CNC lathe, which was imported previously, and new materials using the metal powder injection-moulding technique for the first time in the country.
In addition, he developed a rare earth permanent magnet and succeeded in other important research projects.
