Process for manufacturing articles of thin wall and injection molding an article of thin wall and thin wall tube.A process for the manufacture of articles with thin wall.Comprising the steps of: 1) selecting a polymer blends having a W greater than 10 hours; (I) several (preferably 6 or more) strips of polymer blends incorporating any tratameNo post molding to a final article having the dimensions of the cross section of 0.65 mm thick, 10 mm width is injection molded under high shear.Conditions for the duration of the flow long.Similar to those intended for use in the manufacture of the article of thin flexible wall; (II) the strips are folded back on themselves and wired 3 mm from the bending strip folds; (III)Adas are immersed in a solution of an agent from cracking by stress and maintained at a temperature of 50 u00b0 C; (IV) the strips are observed for signs of cracking.Any signs of cracking is considered as failure; and (V) the time to failure is when 50% of the strips show signs of cracking; 2) fusing the polymer mixture; (3) punching the mixture of P.Olu00edmero merged within a mold.Said mold having a cavity that produces an article having a thin wall thin section smaller than 1 mm thick and the thin section is substantially continuously for more than 50 mm.In the direction of flow of the polymer melt into the mold; and 4) to remove the mold the article wall formed of thin polymer blends.
