IDI Composites International has made a major investment in their commitment to the Thermoset Composite industry, renovating and modernizing their corporate headquarters and manufacturing facility. This included a complete reconstruction of their 110,000 square foot manufacturing operation and a redesign of their 10,000 square foot administrative and sales offices of their Noblesville, Indiana headquarters and manufacturing facility.

The expansion will allow IDI Composites International to better serve traditional markets such as automotive, heavy truck and various consumer industries while also allowing for greater expansion into new and emerging markets like oil and gas, rapid transit, aerospace and alternative energy. The reconstruction of the manufacturing plant gives greater capacity for the production of their traditional Sheet Molding Compounds (SMC) and Bulk Molding Compounds (BMC) as well as their newest line; Structural Thermoset Composites (STC®), which meet a wide variety of requirements for the most demanding applications.
