Queen City Forging Company has worked with IHT for over 15 years. They have supplied IR furnaces and worked closely with us on ongoing routine repairs and maintenance of the equipment. We have experienced exceptional up-time and quick response to our needs when inevitable failures occur. Working with them over the years it is obvious their designs have continued to innovate and improve and the range of applications have grown significantly. We consider IHT and improtant partner in our success.
