Many companies are imitators in the manufacturing industry, claiming to “comply” or “conform” to the ISO standards. Only those holding themselves to a higher standard of quality are certified by an independent third party. We are one of the companies whom hold ourselves at—and above—this higher level of standards with these certifications. We are independently certified by NQA.

Our Quality Management System is supported by our executive management committee, quality management committee, and maintained by all members of D&L Engineering..

As standards go, AS9001C is one of the most widely recognized in the world. The importance of AS9001C is the importance of quality. Many companies offer products and services, but it is those companies who put out the best products and services efficiently that succeed. AS9001C is a standard created to make the attainment of quality, consistent products easier by providing specific steps for development of an organization’s quality management system.

The cornerstone of AS9001C is continual improvement. No company should ever be satisfied with the conditions of a process at the given moment and should always be looking for ways to make these processes more efficient and effective—for themselves and their customers. D&L’s philosophy is premised upon continual improvement, thus the certifications we obtained were a natural evolution in staying true to this philosophy.
