s103, arranging the positioning piece in a second mold, and injecting plastic raw materials for injection molding;

and S104, cooling to obtain the finished product of the long tube.

Example 3

s101, preparing materials, namely uniformly mixing the toner and the plastic raw material for later use, wherein the mass ratio of the toner to the plastic raw material is 0.25%;

and S104, cooling to obtain the finished product of the long tube.
