Our Work
At Big Rocks Engineering, we help companies innovate, streamline operations, and solve complex challenges through engineering and manufacturing excellence. Explore how we’ve supported businesses across industries.

Power Electronics for EV Battery Testing Equipment
✅ Client: A manufacturer of power electronics for battery lifecycle testing
✅ Challenge: Their last product launch was 20 years ago, and they needed a cutting-edge solution to compete in the EV market.
✅ Our Solution: Conducted a Quality Function Deployment (QFD) and focus group study, developed a product requirements document, and led proof of concept, design, and prototyping before handing off for final production.
Our engineering company was engaged by a client to leverage our specialized knowledge in new product development for an autonomous machine specifically tailored for the meticulous preparation of bullet casings in the context of refilling. Our central aim was to attain unparalleled levels of precision in the bullet casing preparation process, which traditionally required manual labor. However, with our advanced autonomous machine, it is now possible to effortlessly initiate the machine and allow it to operate independently, eliminating the need for constant human supervision. To accomplish this, we employed our expertise in various areas, ranging from initial concept design to the meticulous creation of detailed models and drawings. By conducting rigorous design reviews and implementing thorough testing plans and procedures, we ensured the optimal performance of the machine. To bring the components together seamlessly, we utilized our in-house manufacturing capabilities. The image displayed above showcases our cutting motor subassembly, a critical component of the overall system. Due to confidentiality concerns, we are unable to disclose the name of our esteemed client.
Engineering Resource for an OEM in Farm Equipment
✅ Client: BEC Sales, an OEM selling farm supply equipment in Kansas
✅ Challenge: Needed computer-aided drafting (CAD) capabilities to update product designs and expand their portfolio to stay ahead of new competition.
✅ Our Solution: Provided automated drafting expertise, enabling faster design updates and market expansion.
Electrical Enclosures for HVAC Systems
✅ Client: MCS Electrical Enclosures
✅ Challenge: Needed a supply chain partner to not only manufacture electrical enclosures for HVAC systems but also manage inventory levels.
✅ Our Solution: Leveraged Mack Hils Metal Fabrication to provide quality manufacturing and ongoing inventory management to ensure consistent supply and reduced stockouts.
Kitting & Distribution: Garden Equipment Powder Coating & Logistics
✅ Client: Henderson Garden Equipment
✅ Challenge: Needed a storage, powder coating, and distribution solution for their inventory.
✅ Our Solution: Total Powder Coat & Finish handled container storage, powder coating, and drop shipping directly to customers as orders were placed.
Our engineering company was approached by the client to lend our expertise in various new product development endeavors. One such project involved the creation of a cutting-edge cooling mattress topper aimed at preventing the occurrence of ulcers in hospital patients. The prototype incorporated a sophisticated heat sensor that triggered a cooling mechanism, facilitating the release of cold air precisely where needed.
In another instance, we undertook the challenge of developing an elevating back support system. Instead of investing in a mattress with built-in elevation capabilities, our solution entailed designing an accessory to be placed atop the existing mattress, achieving the desired results without the need for an entirely new bedding setup.
Harnessing our technical acumen, we successfully transformed these conceptualizations into tangible realities, delivering fully functional prototypes on both occasions. However, in order to respect the confidentiality of our esteemed client, we are unable to disclose their identity.
High-Mix, Low-Volume Manufacturing for Various Industries
✅ Clients: Essex Industries, ITW, Sherwin Products
✅ Challenge: Needed a supply chain solution for high-mix, low-volume production across industries like flow control, heavy trucking, and agriculture.
✅ Our Solution: Provided precision machining, fabrication, and stamping services to support diverse product lines with flexibility and efficiency.
Our engineering company was approached by clients who presented us with a complex ladder and large metal enclosures, seeking our expertise in reverse engineering these products. Taking on the challenge, we meticulously analyzed and deconstructed the items to extract crucial technical specifications. These specifications were then meticulously documented and compiled into comprehensive technical specifications ready for production, allowing our clients to proceed with the mass manufacturing process.
