Two researchers work on developing an automatic screen printer at the Ryuwon Footwear Factory.
“I can do it, too,” says every employee of the Ryuwon Footwear Factory.
With the firm confidence that they can carry on technical innovation, its employees think deeply to raise the rate of domestic production of raw and other materials and improve the quality of products.
In the course of this, they conceived an idea to remodel a manual ring-inserting machine into an automatic one and succeeded in its making through repeated tests. They also brightened the local illumination of each machine to further reduce electricity consumption and improve production conditions.
A worker at the laboratory of the factory found out a method of substituting a locally-abundant material for an imported reagent capable of promoting resistance of vinyl chloride to cold, thereby completing the production method of winter shoes based on waste vinyl chloride and making a contribution to the domestic production of materials and recycling.
It is said that the sci-tech classes hosted by the factory were very helpful to making such successes though they did not receive university education.
They said that they could acquire special knowledge related to the production of footwear and make technical innovations in the course of studying hard as they competed with and taught each other.
