Our Comprehensive Sheet Metal Assembly Process

Our integrated sheet metal assembly process is designed to achieve maximum clarity. We first review the feasibility of the design engineering support and determine the foundation for your project. Next, we perform precision sheet metal fabrication to create components to exact specifications. Like: Cutting、Bending、Forming、Stamping. Finally, each sheet metal parts are connected through assembly techniques and assembled into a complete functional product in the final stage.

Frequently Asked Questions

What is your lead time for sheet metal assemblies?

Our standard lead time for most sheet metal assemblies is approximately 10-14 business days from the final approval of your design. However, this can vary based on part complexity, material availability, and finishing requirements. For urgent projects, we offer expedited services to accelerate your timeline. Please submit your project details for an accurate quote and a precise delivery schedule.

What types of assemblies can you complete?

We specialize in a broad spectrum of custom assemblies, from simple hardware insertion (PEMs, studs, standoffs) into brackets and enclosures to complex weldments and large electromechanical systems. Our team is equipped to manage multi-component projects that require the integration of machined parts, wiring, and diverse finishes, delivering a product that is ready for immediate use.

Besides sheet metal processing, what other manufacturing processes do you offer?

We operate as a comprehensive manufacturing partner. Beyond our core sheet metal capabilities, we offer extensive in-house services, including precision CNC Machining, Vacuum Casting, and a full range of Finishing, like powder coating and anodizing. This single-source solution streamlines your supply chain, reduces logistical complexity, and ensures perfect component compatibility from start to finish.
