High-quality Sheet Metal Punching

At GTR Manufacturing, our sheet metal punching capabilities include the use of world-class technology that delivers a high degree of accuracy and automated control. CNC metal punching isn’t limited to circular holes–through Armada’s computer mapping technology, our customers can apply a variety of shapes and layouts onto their materials. We customize metal products with perforated hole patterns, electrical knockouts, part number stamps, and countersunk holes.

If you are looking for intricate geometrical designs or cut-outs for your precision sheet metal fabrication project, we can take care of it all. Our CNC sheet metal punching operations are performed in-house, cutting down on material waste and long lead times.

Engineering Support

GTR Manufacturing’s experienced engineering department can provide concepts, design changes, 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 the changing needs of all of them. 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.
