# Dependable Pattern Works > Official Dependable Pattern Works business agent. Dependable Pattern Works is a Portland, Oregon pattern and machine shop providing CNC machining, 3D… ## Ask it a question Dependable Pattern Works answers for itself at https://api.hailera.com/mcp/dpwcorp. A client that speaks MCP can connect to that address; the tool is ask_dpwcorp and the protocol is 2026-07-28. Where this file and the agent disagree, the agent is current. ## About Dependable Pattern Works DPW was founded in 1933, during the Great Depression, initially serving the food processing industry before moving into pattern equipment for the coal and oil heating furnace market. Carl G. Mattson became a partner and later the company's leader, described on the site as shaping DPW into "a world-class pattern and machine shop." During World War II, DPW's production shifted to support the military effort as part of Oregon War Industries. In the 1950s, DPW developed and sold the Dependable Shell Core Machine line worldwide for over 50 years. In the 1970s, DPW worked with Boeing engineers on tooling for what the site describes as the largest aluminum casting used in an aircraft at the time. In 1982, DPW purchased a McAuto Unigraphics 1.0 CAD/CAM system and two Mazak CNC milling machines, which the site says began a technological shift in how the company made tools. In 1988, Carl Mattson turned the company over to his son, Tom Mattson, under whose leadership DPW added CNC machines, 3D printing, and 3D scanning. The site states different figures for how long DPW has operated: the home page says "For 90 years," the Our Story page header says "Celebrating over 85 years of service," and the DPW Difference page says "more than eight decades." Given this inconsistency across the site's own pages, no single years-in-business figure is asserted here beyond the founding year of 1933, which is stated directly and consistently. The DPW Difference page also states the company has staff with "over 100 years combined tooling experience using CAD/CAM systems" and describes an apprentice training and continuous improvement program. The equipment list page details inspection tools including a Brown and Sharpe 34-inch Micro-Hite height gauge and a Gage Master 14-inch optical comparator. The site does not name or display any ISO, AS9100, ITAR, or other formal certification number.

Its contact page states the company's location is "Portland's Central Eastside Industrial District, near the east end of the Hawthorne Bridge and OMSI," and gives driving directions from I-5 South, I-5 North, and from Portland International Airport (PDX). The site does not publish a street address or ZIP code as plain text, so none is given here; anyone needing a precise address should call to confirm before a visit. The published phone number is 503-239-5464. The contact page also offers an email option ("send us an email") but the address itself is not shown as plain, readable text in the page's underlying content, so it is not reproduced here. The site does not state office hours, days open, or any way to book or schedule an appointment online; there is no booking or scheduling tool described anywhere on the site. For pricing or a project quote, the contact page's own stated process is: "Questions? Looking for a quote? Give us a call or send us an email - we'd love to help!" DPW does not publish specific prices, rates, or fees for any service, and no cost range, minimum order, or turnaround estimate appears anywhere on the site. The site does not define a specific geographic service area beyond describing the Portland location; whether DPW takes on work from outside the Portland area is not stated. Lists Central, Hawthorne, Whitney, and Portland as a location. Names Oregon as a service area. Areas beyond these are not published.

Unlike a CMM, which the site says only inspects discrete points, DPW states that 3D scanning supplies complete digital model data useful for reverse engineering, quality inspection, and resolving manufacturing process issues. Listed uses include documenting as-built manufacturing modifications, measuring part dimensions, acquiring geometry for reverse engineering, ensuring assembly fit, process capability studies, producing rapid prototype data, documenting wear and predicting end of life, identifying part distortion or warpage, determining shrink factors, identifying tooling errors, mapping deviations for weld repair, and root cause analysis. The equipment list page names a Faro Edge 9-foot arm with a Faro HD laser scanner and Polyworks 2023 software for scanning, and two Stratasys FDM 400mc machines plus one Stratasys FDM 450mc for rapid prototyping, each with a 16 x 14 x 16 inch build envelope. The site lists 3D scanning, reverse engineering, and rapid prototyping among DPW's five precision services, but the rapid-prototyping and reverse-engineering pages themselves carry minimal description beyond navigation and gallery links. No pricing, rates, or fees are published for these services, and DPW does not state typical scan or print turnaround.

It states DPW can machine complex geometries and difficult angles in a single setup, or multiple setups when necessary, using 5-axis machining, which it says minimizes setup error and improves accuracy. Listed applications include assembly fixtures, book molds, carbon fiber fixtures, ceramic core molds, check gauges, compression molds, inspection fixtures, plastic injection molds, prototype parts, rubber molds, display and sales models, short-run machining, vacuum forming molds, wax injection molds, and wax assembly fixtures. The site's separate equipment list page names specific CNC machining centers, including an Akira Seiki HSV-1150 (3-axis, 20 HP, 8,000 RPM, 45 x 25 x 26 inch envelope), an Akira Seiki HV-5.5A (3-axis, 20 HP, 8,000 RPM, 53 x 25 x 26 inch envelope), a DMG/Mori Seiki 5-axis machine (Siemens 840D control, 47 HP, 18,000 RPM), a Mazak V7.5, a Mori Seiki, two OKK vertical machining centers, and a Pratt and Whitney Viking with a 96 x 60 x 26 inch envelope. These figures describe machine capacity as published, not a guarantee of what any given part can achieve. DPW does not state pricing, rates, or turnaround for CNC machining work on its site; customers are directed to call or email for a quote or estimate.

The company says the value it adds comes from years of experience with shrink factors, pattern and core clearances, draft angles, wood layup structure, and structural reinforcement, developed through familiarity with individual customers' processes. Materials listed for pattern and tooling work include wood, fiberglass, carbon fiber, plaster, silicone rubber, polyurethane, aluminum, steel, cast iron, brass, copper, and plastics. Tooling types listed include loose patterns, cope and drag boards, fiberglass layup molds, plaster molds, epoxy molds, foam nesting fixtures, and silicone rubber molds. The pattern-making page does not give prices, rates, or fees for any of this work, and does not state typical turnaround times. It links to a photo gallery of pattern work but does not name specific customer industries beyond the general foundry and tooling context described elsewhere on the site. Anyone wanting a cost estimate or quote for a pattern-making project is directed to contact DPW directly rather than relying on any figure published on the page.
