Ron Witherspoon Inc. has been at the forefront of precision manufacturing for the high tech, medical, aerospace and defense industries since 1977. RWI is a woman-owned company with facilities in the heart of Silicon Valley and near the Monterey peninsula. We are ITAR approved and ISO 9001 certified. RWI is one of the largest privately-owned manufacturing companies on the west coast. RWI consistently delivers quality products on time and on budget, while also taking on, and successfully completing, many jobs that other manufacturers have deemed “impossible”. Our highly skilled employees are dedicated to exceeding our customer’s expectations and take pride in the parts they produce. RWI has an in-house engineering department to assist our customers in planning both prototype and production manufacturing. Our quality control department excels at all levels of inspection. RWI is much more than a supplier of your parts; we are your partner for success. RWI has extensive experience in precision manufacturing parts from all types of metals and plastics—from the most common steel and aluminum alloys to more exotic materials such as tungsten, titanium, beryllium copper and Glidcop. Additionally, we provide a wide selection of manufacturing capabilities ranging from standard vertical and horizontal CNC milling to 5-axis and micro-milling; from sinker and wire EDM to fine wire EDM: from turning to screw machines to micro-turning and mill/turn. Our dedication to absolute precision and quality is what has driven RWI’s success, and how we have earned our reputation for being able to produce the best parts in the industry. “RWI is committed to the delivery of product that meets or exceeds the customer’s expectations, as well as all relevant requirements, and to the continual improvement of all business functions and processes.” – Monica Witherspoon, CEO & Owner, Ron Witherspoon, Inc.
