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.
Claims8
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, said microbubble generating member comprising a perforated tip, the microbubble creating method comprising the steps of:
- a) driving said feed screw to propel a fluid polymer into a 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.
