Our customers need confidence in no product variation.  Their products are critical, with dimensional requirements of +/- 10-20 µm (+/- 0.0004”-0.0008”) and even tighter in some cases. Our customers have many and varied needs that we work to meet or exceed, including dimensional stability, color requirements, complex visual criteria, structural integrity, and processing.


With the nature of our customer product needs being specific and technologically complex, quality and process documentation must be complete, uncomplicated, and technically for a repeatable and consistent manufacturing process.


Our in house and third-party supply chains are reliable, giving our customers confidence that even in times of supply chain upset, their parts will get to them on time.  Along with our quality documentation, lot and product tracking ensures our customers can track and manage their orders and have visibility into real-time data on their orders and schedules.


Customers who wish to move production to the USA, tackling complicated product development, or searching for more sophisticated suppliers can receive engineering and manufacturing attention within their timeline and utilizing innovation, technology, and dedication to solve their needs.  Those new to the process or those looking to make supplier changes come to us for DFM and feasibility reviews, material recommendations, and informative cost analysis, including tooling and molding and related add-on services.


We are looking to partner with customers who want improvement or assistance in these areas so that we can help them grow and produce quality and dependable products without interruptions or headaches common to the supply chain and the typical manufacturing process.
