Abstract
A microbubble creating method using a forming machine for creating microbubbles by: installed a microbubble generating member in a mold, feed screw or barrel for enabling a perforated tip of the microbubble generating member to be surrounded by the applied fluid polymer so that when a high pressure high temperature gas is delivered through the perforated tip of the microbubble generating member, microbubbles are created with well mixed with the fluid polymer, and the expected foamed polymer product is thus obtained after cooling.

A microbubble creating method for creating microbubbles in a polymer using a forming machine, said foaming machine comprising a feed screw and a microbubble generator, said microbubble generator comprising a microbubble generating member mounted in a mold, said microbubble generating member comprising a perforated tip with extended into said mold, the microbubble creating method comprising the steps of:
- a) driving said feed screw to propel a fluid polymer into said mold, enabling said perforated tip of said microbubble generating member to be immersed in the fluid polymer and be surrounded by said fluid polymer;
- and
- b) starting up said microbubble generator to generate a high pressure high temperature gas, enabling said high pressure high temperature gas to create microbubbles for mixing with said fluid polymer in said mold when passed through said perforated tip of said microbubble generating member.
A microbubble creating method for creating microbubbles in a polymer using a forming machine, said foaming machine comprising a feed screw and a microbubble generator, said microbubble generator comprising a holder member and a microbubble generating member, said holder member comprising a runner disposed in communication between said feed screw and a mold, said microbubble generating member being mounted in said holder member, said microbubble generating member comprising a perforated tip with extended into said runner, the microbubble creating method comprising the steps of:
- a) driving said feed screw to propel a fluid polymer into said runner of said holder member toward said mold, enabling said perforated tip of said microbubble generating member to be immersed in the fluid polymer and be surrounded by said fluid polymer;
- and
- b) starting up said microbubble generator to generate a high pressure high temperature gas, enabling said high pressure high temperature gas to create microbubbles for mixing with said fluid polymer in said runner when passed through said perforated tip of said microbubble generating member.
A microbubble creating method for creating microbubbles in a polymer using a forming machine, said foaming machine comprising a feed screw and a microbubble generator, said microbubble generator comprising a locating ring and a microbubble generating member, said locating ring being mounted at a front end of said feed screw, said microbubble generating member being mounted at said locating ring, said microbubble generating member comprising a perforated tip protruded over the surface of said feed screw, the microbubble creating method comprising the steps of:
- a) driving said feed screw to propel a fluid polymer, enabling said perforated tip of said microbubble generating member to be immersed in the fluid polymer and be surrounded by said fluid polymer;
- b) starting up said microbubble generator to fill a high pressure gas into an air passage in said feed screw, enabling said high pressure gas to be heated when flowing through said air passage;
- and
- c) enabling the heated said high pressure gas to flow from said air passage of said feed screw into said microbubble generating member for creating microbubbles after passed through said perforated tip of said microbubble generating member so that the created said microbubbles are mixed with said fluid polymer subject to rotation of said feed screw.
A microbubble creating method for creating microbubbles in a polymer using a forming machine, said foaming machine comprising a barrel, a feed screw and a microbubble generator, said barrel comprising an input end and an opposing output end, said feed screw being mounted in said barrel, said microbubble generator comprising a microbubble generating member mounted in said output end of said barrel, said microbubble generating member comprising a perforated tip with extended into said barrel, the microbubble creating method comprising the steps of:
- a) driving said feed screw to propel a fluid polymer from said input end of said barrel toward said output end of said barrel, enabling said perforated tip of said microbubble generating member to be immersed in the fluid polymer and be surrounded by said fluid polymer and heated in said barrel;
- b) starting up said microbubble generator to fill a high pressure gas into an air passage of said barrel, enabling said high pressure gas to be heated when flowing through said air passage;
- and
- c) enabling the heated said high pressure gas to go through said air passage of said barrel into said microbubble generating member to create microbubbles for mixing with said fluid polymer subject to rotation of said feed screw after passed through said perforated tip of said microbubble generating member.
