“We have been working with Applied Process for over ten years and opportunities continue to grow.  We offer customers the benefit of looking to Austempered Ductile Iron as a replacement for steel fabrications, steel castings and forgings by working with the AP Sales and R&D teams to determine the feasibility of conversion to ADI.  We then work jointly with the customer to quickly determine the best path forward to minimize timing, cost and risk.  The relationship is such that the opportunities we have developed together produce results that are beneficial to everyone.   Once in production, the operations staff give us timely communication about order status and are always available to assist with special requests and expedites as they arise.  Our relationship has grown and is based in trust, confidence and reliability that will lead to increasing business in the future.”
