The Pyongyang Textile Machine Factory has newly built a combustion model casting process.
“Until a few years ago, we used to ask a machine research and manufacturing unit to make the main body and other castings for air jet loom,” said Kim In Phal, a workteam leader of the factory.
So, it was hard to ensure the period of loom production to be supplied to textile mills every year.
The factory buckled down to establishing the combustion model casting process in order to put the production of modern and efficient textile machines on a normal footing.
“As the labour- and energy-saving combustion model casting method is widely used in the field of castings, it is simpler in the casting production process and has higher surface precision of castings than the traditional casting method and helps produce castings with complicated structures,” said Kim Kun Hyok, a technician of the factory.
The factory carried out the renovation project of different buildings for mould processing, painting and other main work areas, manufactured necessary facilities, developed their programs and invented and introduced various jigs and tools.
In particular, it confirmed the position and number of gas passing film, thereby ensuring the uniformity of sand injection and completely removing gas from the casting process.
It contrived a vibration sand sorting strainer and efficient dust collecting device to recycle sand and prevent environmental pollution while deciding on the position and size of rational molten iron inlet and designing and manufacturing the general control panel which can automatically control all machine elements.
Besides, it set up the combustion model casting process in a short time by solving technical problems including the thickness of paint layer and the intensity of vibration compaction in conformity with its specific conditions.
As a result, the factory laid foundations for making and supplying all castings including the main body of air jet loom by its own efforts.
