AIRCORE (Development of Air Cores for Forming Complex Geometries in Injection Molds)

The aim of the project is to develop an innovative technology in addition to the known solutions for the creation of complex angle geometries in plastic injection molds.

With the project, a new molding technology will be developed as an alternative to collapsible core and scraper core technique used to form a gasket channel in the plastic pipe industry. The target product for the production of reverse angled forms with air power is the gasket channels in the wastewater pipe fittings products.

The Aircore core will serve as a mechanical core within the system, while the gasket channel will be formed with the air passing through it. It is also important to improve the cooling quality of the surfaces of the core in contact with the plastic in the molten phase. Form Conformal Cooling ”technique was applied on the model in order to increase the cooling quality. The geometric elements required for efficient cooling are considered in the modeling. The designs are supported by mechanical and flow analysis.

When making mold and product design, dimensions and working positions of the core were taken into consideration. The region where the molten plastic will move is formed on the model and on the core insert, the operation of the double-acting hydraulic piston is provided.

The air core technology developed within the scope of the project is designed and manufactured as a prototype of 2-chamber Wastewater Cuff mold using AIRCORE technology. The product and production technology were successfully completed by making trial productions.

The project output is protected under the name of Molding core, mold and fluid-aided molding method, PCT / TR2015 / 050286.
