From CAD to Part: The Process

From CAD to Finished Part: Honyo Prototype’s Sheet Metal Workflow

At Shenzhen Honyo Prototype, our sheet metal fabrication process is engineered for precision, efficiency, and seamless client collaboration. We transform digital designs into high-quality physical components through a rigorously defined workflow centered on three critical phases: AI-Powered Quoting, Design for Manufacturability (DFM) analysis, and Precision Production. This structured approach minimizes delays and ensures optimal manufacturability from the outset.

The workflow begins the moment a client submits a CAD file. Our proprietary AI quoting engine instantly analyzes the geometry, material specifications, and geometric complexity. This system rapidly calculates material utilization, machine time estimates, and secondary operation requirements against our extensive cost database. Unlike manual quoting, this AI-driven step delivers highly accurate cost projections and lead times within minutes, providing immediate clarity for project planning and budgeting. The speed and data-driven nature of this phase empower clients to make informed decisions rapidly during the design iteration stage.

Following quote acceptance, the CAD model undergoes mandatory DFM analysis by our experienced manufacturing engineering team. This is not a passive review but an active collaboration. Engineers scrutinize the design against our production capabilities and industry best practices, identifying potential issues such as insufficient bend radii, improperly placed holes near bends, inadequate flange lengths, or material thickness inconsistencies. We provide specific, actionable feedback and optimization suggestions directly to the client’s design team. Resolving these manufacturability concerns before tooling or cutting commences prevents costly rework, reduces lead times significantly, and guarantees the final part meets both functional and quality requirements. Key geometric tolerances achievable through our standard processes are outlined below.

| Parameter | Standard Tolerance | Precision Capability |

| :—————– | :—————– | :——————- |

| Linear Dimension | ±0.1 mm | ±0.05 mm |

| Hole Position | ±0.15 mm | ±0.08 mm |

| Bend Angle | ±1.0° | ±0.5° |

| Edge Misalignment | 0.1 mm | 0.05 mm |

With DFM sign-off complete, the approved design moves directly into production. Our integrated manufacturing cell utilizes state-of-the-art equipment. Fiber laser cutters execute precise contour cuts and hole patterns from the native CAD data. CNC press brakes, programmed directly from the 3D model, form complex geometries with consistent accuracy, leveraging our documented bend allowances. Secondary operations, including welding (TIG, MIG, spot), hardware insertion, and surface finishing (powder coating, anodizing, plating), are managed within our facility under strict process controls. Throughout production, in-process inspections verify critical dimensions against the engineering drawing at defined checkpoints.

The final stage involves comprehensive First Article Inspection (FAI) and batch sampling per AS9102 or client-specified standards. Dimensional reports, material certifications, and finish validation documentation accompany every shipment. This end-to-end workflow, from instantaneous AI analysis through proactive DFM collaboration to tightly controlled production and rigorous QC, is the foundation of Honyo Prototype’s commitment to delivering flawless sheet metal components on time, every time. We bridge the gap between design intent and manufacturable reality.
