company history
SERVING CUSTOMERS FOR OVER 25 YEARS
In September of 1999, brothers Lee Dundas Jr. and Kelly Dundas founded their injection molding company in Newberg, Oregon, building on a rich legacy in the plastics industry. Their journey began under the guidance of their father, Lee Dundas Sr., who had established Quality Plastics in 1966. This pioneering company laid the groundwork for the family's expertise before his retiring and Quality Plastics being sold to another injection molding firm in 1994.
Lee Jr., after decades of leadership retired and passed the torch to Kelly in 2021, marking a new chapter for their company. By 2025, the next generation had already begun to leave its mark, with Kelly’s son, Elliott Dundas, stepping up as Vice President and part owner at 3D Plastics Inc.
Throughout the years, 3D Plastics Inc. has nurtured a strong family-oriented culture, proudly employing five members of the Dundas family presently. This commitment to family and innovation continues to drive their success in the ever-evolving world of plastics.

ISO 9001:2015
What is ISO?
ISO 9001:2015 is a quality management system standard that presents guidelines intended to increase business efficiency and customer satisfaction.
How do you implement an ISO 9001:2015 certification?
Implementation starts within the company. Implementing ISO 9001:2015 is the gathering of all your company’s processes and documenting them. Do what you say and say what you do. Then audit those processes for repeatability and effectiveness.
What does ISO mean to you?
With ISO 9001:2015, each company that participates in the process of manufacturing and/or developing a product knows that ISO is part of an internationally known, reliable system. And because the customer is most important to a company, ISO 9001:2015 makes the customer its focus.
