Total Quality Management (TQM)

Don-Nan's "TOTAL QUALITY MANAGEMENT" extends beyond manufacturing to all aspects of business, including sales, finance, service, support service, planning, and others.

TQM is doing things right the first time, throughout the organization, by everyone. At Don-Nan, quality means more than complying with the API Spec. 1 and API 11AX requirements or customer specifications. Meeting expectations isn't enough. Quality is working to exceed expectations, doing things right the first time, anticipating and responding to customer needs, while ensuring customer satisfaction. Whether you need a quick response, prototype, or "build-to-print" production, our complete manufacturing center offers a ready solution.
