Microwave System for Foundry Core Drying

Electromagnetic Technology is effectively used in Foundry Industry for Core wash Drying, Core Coating Drying, Resin Core Curing Application.

Twin Engineers is the leading manufacturer of Microwave Foundry Sand Core Drying System in India.

"TWIN" Electromagnetic System is specially designed for Foundry Industries for sand core drying & resin core curing. This is cost effective solution for Foundry Industries.

The ability of Electromagnetic energy to selectively heat certain materials such as water while not heating - sand cores, Styrofoam patterns or investment casting wax is of great benefit to the foundry for high speed drying and processing.

This technology is also used for Layer Drying & de-waxing of investment casting.
