Profiles and pipe can be injection molded using “indefinite-length” technology developed by Continuous Moulding Technologies Pty. Ltd. of Baranduda, Australia, which has been granted a U.S. patent.
Inventor Michael Privan, a veteran toolmaker, got the idea for the requirement of a structural core for the textile winding industry measuring 50 millimeters in diameter by 6 meters long. Privan developed a tool and the necessary minor machinery alterations to make his vision for indefinite-length molding.
The high-speed winding sector remains a market today, where CMT said its polypropylene core is cheaper and more stable than the standard structural cardboard.
CMT officials said the small footprint required to make pipe using its process lends itself to a mobile line producing pipe right at the worksite. The process also allows continuous molding of long-fiber materials.
Also, many dimensions can be added to the profile or pipe by using injection molding tooling techniques such as split tooling, core pulling and unscrewing. CMT has tested glass-reinforced nylon pressure pipe for natural gas.
The company was formed by Privan and his associate Don Ryan.
