DN3000 mold R & D success
As the host device out of the amount of increase in diameter 3M in diameter pipe production has become a reality. But as the mold equipment, has become a technical difficulty. Because more than 3M in terms of large-diameter mold design and manufacturing, there are many problems. However, our difficulties, a lot of manpower and material resources and financial resources to overcome all difficulties, overcome various technical difficulties, and finally developed the DN3000 and above, and successfully applied to the mold production.
