Rapid Sheet Metal Fabrication Process

Step 1: Submission of Drawings and Technical Specifications

The customer provides 2D engineering drawings, 3D CAD files, or physical samples, specifying materials, dimensions, tolerances, surface finishes, order quantities, and expected delivery times.

Step 2: Process Evaluation and Quotation

Based on product structure, manufacturing complexity, and order requirements, we evaluate processes such as laser cutting, stamping, bending, tapping, and surface finishing, and confirm a feasible production plan.

Step 3: Sample Fabrication

For R&D or validation projects, sample fabrication is arranged upon request to facilitate dimensional inspection, assembly verification, and visual assessment.

Step 4: Production and Quality Inspection

Production is carried out in accordance with confirmed engineering drawings, process plans, and acceptance criteria; dimensional, visual, and other necessary inspections are performed as agreed upon for the project.

Step 5: Surface Finishing and Delivery

Surface treatments—such as anodizing, powder coating, painting, or other applicable processes—are completed according to order specifications; the products are then packaged and shipped based on the confirmed delivery schedule.
