Introduction Double L-ring 200 liters large barrel of materials is a large hollow blow molding products，such a large barrel of materials manufactured by extrusion blow molding method, Extrusion blow molding is the blow molding method for molding one of the three[5].
System design ideas According to the two L-ring drums of 200 liters of large material requirements, first in the three-dimensional modeling environment solidworks design 200 liters barrel three-dimensional model of large materials, then built by stacking three-dimensional stress analysis of materials bucket model, recycling the obtained analysis results to optimize the design, Optimize and verify whether the results meet the requirements, finally, there is then the optimized 200 liters of large material bucket drop test to verify the material barrel drop breakage, and ultimately determine whether the end of the design.
