On November 24th, the Lies Company's manufacturing department was independently developed and designed by Sun Baolong, the manager, and a three-screw double-layer extrusion die machine processed by the equipment maintenance department passed the acceptance test after one month of trial operation. This signified that the technology and die manufacturing design of Liex Company reached the leading level in the industry and filled the domestic gap. The triple-screw double-layer extrusion die is a newly emerging extrusion mode in the international blow-molding industry. It can be molded in one of three materials, and can also be extruded in a composite color. It can simultaneously extrude three types of screw-shaped preforms. Multi-point control ensures the blowing quality.
At present, there are only a few professional blow molding machinery manufacturers in foreign countries that can complete the design of such die heads. No domestic manufacturer can produce the same type of die heads. It is reported that the die can produce 1-5L various types of blow molding bottles of 6,000, which will provide a solid backing for the sustainable development of Shanghai Lishi.
