Engineering Support

GTR Manufacturing’s experienced engineering department can provide concepts, product enhancements, and reverse engineering. We will work with your team to deliver your parts at competitive costs.

Our sales, management, and engineering teams have experience in a wide range of industries and understand their changing needs. We work in close partnership with our clients in developing and refining product designs and production process planning to simplify manufacturing and create cost savings for your end product.

We have the capability to import and unfold your 3D models ( .dwg, .step, .iges, .sldasm, .ldprt, .dxf) built in Solid Works, Pro/E, and other modeling software. The model is unfolded and downloaded directly into the CAM process, reducing errors and assisting in short lead times for your sheet metal parts.



By using the Just-In-Time (JIT) inventory strategy, GTR Manufacturing schedules production to meet your ordering needs. We reduce costs by carrying less idle inventory, resulting in a quality product that is delivered on time at a lower price.

We pair JIT with the Kanban technique to manage our highly-efficient development process. We establish minimum and maximum quantities, fulfilling customer needs on a pull system. This method empowers us to reduce inventory for customers and suppliers and uses lean production practices. In addition, we have full insight into your pipeline through an online portal, ensuring it’s always full.

Are GTR’s CNC Milling and Turning Services Right For Your Next Project?

  • Is your business in need of custom metal work that adheres to specific requirements?
  • Have other manufacturers looked at your blueprints and ruled that your systems are “too difficult” or complicated to create?
  • Are you looking for a straightforward job but are surprised at how long the lead times are?

We are proud to simplify the machining processes by offering CNC milling and turning as part of our one-stop-shop capabilities to speed up project timelines and lower the risk associated with relying on external supply chains. With complete oversight and control over the entire production process—from prototyping to shipping—GTR ensures uncompromised, on-time quality and delivery.
