Quote / Order Placing
Once your design is complete, you’ll request a quote for a prototype on our website. Our online quoting system will prompt you to include all the critical information we need to provide you with an accurate quote.
Gathering information up front reduces back and forth. And because our system is entirely digital, all of your project details are automatically added to our work queue—no manual data entry is required. Ultimately, our efficient approach to quoting and order placing ensures that we can start your project quickly and seamlessly.
When your part is ready to enter production, our team uses a 3D CAD model to program our laser cutter, press brake, or other computer-controlled machines used in the fabrication of your part. This automated process removes the risk of human error and allows us to identify potential issues with the part before fabrication begins.
Next, fabrication begins using one or more of our in-house metal fabrication processes, such as laser cutting, punching, forming, or welding. Many parts require several different operations.
If you request finishing services, we will clean and prepare your parts in accordance with the finishing method you choose and then apply a high-quality finish.
