The invention provides a manufacturing method of a high-strength anti-aging cable protection 
pipe. The manufacturing method comprises the following steps of a, stirring, wherein 100 parts of high-density 
polyethylene resin, 0.8-2.2 parts of an 
antioxidant, 1-4 parts of a lubricating agent, 0-40 parts of a filling agent, 6-20 parts of a 
plasticizer, 0.5-1.5 parts of a stabilizer and 4-8 parts of color 
masterbatch are weighed and placed into a stirrer for stirring treatment; b, 
drying, wherein a mixture is dried through a 
drying machine; c, 
extrusion and molding, wherein 
extrusion treatment of the mixture is carried out through an extruder, and the mixture enters a mold for molding treatment after 
extrusion; d, shaping, wherein shaping treatment of a semi-finished 
pipe is carried out; e, cooling, wherein the semi-finished 
pipe is cooled through cooling equipment; f, 
cutting, wherein the semi-finished pipe is 
cut through slitting equipment; g, 
polishing, wherein an end opening of the semi-finished pipe is polished through an end opening 
polishing device; h, spraying, wherein surface spraying treatment of the semi-finished pipe is carried out through a surface treatment device; and i,code spraying, wherein code spraying treatment of the semi-finished pipe is carried out through an automatic code spraying 
machine.
