Project Management
Every project has quality assurance built in from the start and is managed by an experienced project manager. By communicating with our customers and performing a complete contract/specification review up front, we develop a quality and manufacturing plan that meets the requirements of the project. That way the correct checks and inspections are performed at the proper time in the manufacturing process, eliminating surprises at the end.

You guys do spectacular work such perfectly polished seams! Thank you for getting it overnight-ed to me. Anderson Dahlen is first on my list to get the special things done from here on out. Tim, Wonder Works Unlimited
Thank you to you and your team who assisted me during my visit. Both the customer and I were hugely impressed with everything from start to finish. The actual FATs were one of the smoothest that I have experienced in 20 years. I look forward to working with you in the future. Martin Kelly, Thermo Fisher
We want to let you know how much Brian and I appreciate you, Greg, Nathan, and the rest of the Anderson Dahlen team for helping us to complete the test assembly and collect the test data on time during our visit. Your help truly exceeded our expectations. We thank you for showing us your manufacturing plants. Vincent Lee, Plasma-Therm NES
Thank you to Gary and the fabricators who helped us remove the scratch and refinishing our aluminum part. You saved us a ton of time and kept us on track for an on time delivery to our customer. We definitely owe you one! Clint Bitterman, VP-Co Owner of Master Tool & Mfg Inc.
Their willingness to spin a large part well off axis made it possible. Their attention to detail made it a success. Equally praiseworthy is their communication during the manufacturing process, assuring the best part.
