Test Devices Improves Overall Production Capacity

In-House Machining Capabilities

At Test Devices, Inc. we’ve made dramatic improvements in production capacity. We are not only producing more, but we’re also doing it faster than ever before. Along with dramatically shorter lead times, record production, and a plan for continued growth and improvement, here’s an outline of exciting developments at Test Devices.

Test Devices Improved Production Capacity

To appreciate our remarkable growth in production, you just need to look at the numbers. In the first quarter of 2017, we shipped 480 pieces. By the same time in 2018, that number grew to 915, and in 2019 it has more than doubled to 1,873 parts. Our capacity has continued to increase in the last four months, and we are poised to hit a new record high of 800 pieces a month.

One of the ways we have expanded production capacity, and speed, is with our new and expanding machining operations. Previously, we had to outsource forging machining to other facilities. Transit time and queue times added significant delays, which added considerable time to projects. With our enhanced and growing machining capabilities, we’ve eliminated those delays. Parts go through machining, to spinning, with improved velocity.  This has enabled us to achieved a same-day turnaround in some cases.. We’ve also added balancing equipment, and our post balance spin testing allows us to prove out the balancing operations. We are capable of pre-spin  machining, spinning, and post-spinning machining, all in-house, so processing is more efficient than ever. 

Another boost to our growth is the group of talented post-graduate engineering students we work with. Through this partnership, we provide them with the opportunity to begin their career in aerospace. They join us to learn the business from the ground up, and their detailed knowledge of our operations helps them seamlessly move into the engineering side of the company. This gives them concrete knowledge about our operations before they dive into the intricacies of the aerospace industry.

Our ability to manage larger volumes, in less time, means we can serve customers as they grow. This eliminates the need for customers to line up second or third backup supply houses, making their process simple and streamlined with one vendor. We’re not only helping our current customers with quick turnarounds, and increased production volumes, but we are also reaching out to new customers to expand our business.

All of this adds up to an incredible work environment where the atmosphere is positive and collaborative. Our team works together efficiently and enthusiastically to continue our forward momentum.

Test Devices Inc.’s Improved Capacity

Over the last year, Test Devices has seen a significant influx in the volume of parts that our facility processes on a weekly basis. This increased demand pushed us to re-evaluate whether our methods were providing the best possible experience for our clients.

We’ve made several adjustments to our processes in order to improve turnaround time, capacity, and overall customer experience. We’ve already started to roll out many of these changes, and you will begin seeing them take effect in the coming weeks. The most notable areas of change are:


Many of the parts we process require that a precise measurement be taken both before and after the spin test. In January 2017, we installed a 2nd CMM (scans parts up to 48” diameter) that not only allows us to inspect larger parts, but to inspect multiple parts simultaneously as well.



Spin Rigs

In 2016, we dedicated (2) spin rigs to be used solely for the support of pre-spin and overspeed spin testing. We are also retrofitting another existing machine (available mid-April). With the addition of this machine, we will have a total of (3) machines dedicated to our pre-spin and overspeed spin testing, and Test Devices will be able to better dedicate rigs for specific speeds and part types – ultimately significantly reducing setup times.



Test Devices has added additional personnel to support two shifts of operation in both spin rigs and CMM inspection. We are actively looking for additional candidates as the 3rd spin rig comes on-line.


5S Activity

Last year, Test Devices acquired additional space within our facility, and we immediately went to work to determine how it could be used to maximize efficiency and improve part flow.  A thoughtful reorganization of our layout freed up a significant amount of room, which is now expressly dedicated to handling the increased volume of pre-spin and overspeed spin testing.


Improved Scheduling

We have recently instituted the use of a whiteboard to improve scheduling and better ensure we meet customer commitments.
