Shamrock Engineering was founded by David Dunn, who has over 25 years of experience in the machine building industry. While purchasing automated equipment for a major corporation, David discovered a shortage of reputable companies able to manage projects under $150K. Most of the larger companies had enormous overhead and facilities which meant they were not capable of being profitable on projects less than $100K; while the smaller companies could not supply the quality and perform the needed amount of work required in a timely fashion. So, in March of 1998--after talking with family, friends and colleagues--David decided to start Shamrock Engineering, Inc. as an industrial equipment and manufacturing company. Since then, Shamrock has gained many years of experience designing and building customized machines and equipment for many different industries, such as consumer products, automotive, medical, defense and green energy.

Shamrock has extensive expertise in the following areas: Lean Manufacturing Cells, Flexible & Scalable Assembly Automation, Synchronous Assembly Systems, Non-synchronous Assembly Systems, Modular Systems, Test Systems, Vision Inspection, Vision Guidance, Robotic Integration, Measurement Systems, Welding Systems, Material Handling Systems, Part Feeding, Data Collection & Traceability.

Shamrock Engineering has the dedicated personal needed to service your automation related needs. We are backed by a complete staff of qualified engineers and skilled tradesmen. Shamrock Engineering continues to position itself to be profitable on smaller projects by keeping overhead costs to a minimum. Our target market area consists of AL, IN, IL, KS, KY, MI, MN, MO, OH, TN & WI; though we have placed equipment throughout the United States, Canada, Mexico and other overseas markets.


To put it simply: Shamrock Engineering builds custom industrial equipment to meet unique manufacturing needs. If you have a manufacturing process--simple or complex--then the odds are that we can provide solutions to automate it.

We excel at creating assembly cells that meet specific production requirements, decrease cycle times, increase operator ergonomics, and optimize workforce usage. Shamrock can also integrate part testing and part marking into any machine we build, such as component performance testing; functional testing; conformance testing; destructive testing; dimensional testing; leak testing; flow testing; and more. 

With a Mechanical Design and Engineering Department, Controls Design and Engineering Department, Manufacturing Assembly Team, and in-house machining facilities we are capable of completing an entire project from concept to commissioning.  We also provide post-installation support that can range from remote troubleshooting to spare parts manufacturing.
