초록

A process is disclosed for the production of molded tubular structural web articles of thermoplastic material comprising the steps: passing molten plastic material into a tubular mold cavity to fill a substantial portion of said cavity; injecting a low viscosity pressurizing fluid into said material in said mold cavity; coordinating the fluid flow rate, pressure, temperature and plastic material volume so that the pressurizing fluid divides into at least two streams on entering said material without causing the low viscosity pressurizing fluid to break t...
