Building top-tier air conditioning cabinets requires both speed and precision. At Custom Rollform Products in St. Louis, MO, we build automation systems that make your factory run better. Specifically, our Tangent Forming tools help you create full cabinet wrappers with perfect accuracy. We focus on helping you reduce waste and increase profit.
Precision Forming and Surface Protection
First, the process starts with a flat metal sheet. Since these sheets often have a shiny paint finish, we built our machines to protect the surface. Next, the Tangent Former starts to shape the metal. The machine bends a sharp 90-degree edge along the top of the housing. Meanwhile, it folds the two sides up to create a clean, three-sided shape. This method keeps the metal smooth and prevents any cracks in the paint.
Strong Joints Without Welding
In addition to shaping the metal, the system handles the assembly. For instance, while the machine holds the sides at a perfect angle, it overlaps the back corners. Subsequently, a built-in locking tool secures these corners for good. By punching three locks into each corner, the machine creates a very strong bond. This removes the need for slow welding or extra screws. Furthermore, this process creates a much cleaner look for the final product.
Smart Solutions for Your Factory
Moreover, we offer different setups to fit your shop floor. You can choose a manual system for small jobs or a full auto line for big orders. As a result, your team makes more parts in less time. You also keep the tight quality levels that modern HVAC parts need. Our machines work hard so your workers can focus on other tasks.
Ultimately, a Custom Rollform Tangent Former helps you work smarter. By automating the folding and locking steps, you cut labor costs and stop mistakes. Therefore, if you want to grow your AC cabinet business, our team is ready to help you find the best machine. We provide the tools you need to stay ahead of your competition.
