Manufacturing Insight: Custom Metal Sheet Fabrication at Honyo Prototype
Custom metal sheet fabrication forms a critical foundation for rapid prototyping and low-volume production across industries including electronics enclosures, medical devices, and industrial machinery. At Shenzhen Honyo Prototype, we specialize in transforming engineered designs into precise, functional metal components with exceptional speed and technical rigor. Our process leverages advanced digital manufacturing to overcome traditional barriers in sheet metal prototyping, where conventional suppliers often prioritize high-volume runs over agile development needs. We understand that early-stage hardware requires dimensional accuracy, material fidelity, and rapid iteration—capabilities embedded in our operational DNA.
Our core strength lies in integrating precision laser cutting, CNC turret punching, and automated bending within a single streamlined workflow. This eliminates external handoffs that typically introduce delays and quality inconsistencies. Material selection initiates the workflow, with our technicians evaluating design geometry against optimal stock parameters to minimize waste and cost. Laser cutting executes complex 2D profiles with kerf widths as tight as 0.1mm, while our AMADA-branded press brakes achieve bend angles within ±0.5 degrees across diverse grain orientations. Every stage adheres to prototyping-grade tolerances that balance speed with functional reliability, ensuring parts integrate seamlessly into your assembly trials.
The following table outlines our standard technical capabilities for custom sheet metal projects:
| Parameter | Standard Capability | Prototyping Advantage |

Beyond primary forming, Honyo integrates essential secondary operations to deliver fully functional prototypes. Deburring occurs inline to eliminate sharp edges that compromise safety and assembly. Precision hardware insertion—including PEM® nuts, standoffs, and weld studs—occurs under torque-controlled conditions. Surface finishing options span technical anodizing (Type II), powder coating (RAL catalog), and conductive plating, all applied with thickness control to maintain dimensional tolerances. Crucially, our engineers conduct Design for Manufacturability (DFM) reviews before cutting begins, flagging potential issues like minimum bend radii violations or hole-to-edge conflicts that could derail your timeline.
Honyo Prototype redefines sheet metal prototyping by merging industrial-scale equipment with a dedicated rapid-manufacturing ethos. We deliver certified, assembly-ready metal components in 3-7 days without requiring custom tooling—accelerating your development cycle while maintaining rigorous quality standards. This capability ensures your design iterations progress reliably from CAD model to physical validation, de-risking the path to量产. Partner with us to transform complex sheet metal concepts into tangible engineering assets with unmatched technical precision.

From CAD to Part: The Process
From CAD to Part: Sheet Metal Production Workflow at Shenzhen Honyo Prototype
At Shenzhen Honyo Prototype, our sheet metal fabrication process transforms your digital CAD model into a precise physical component through a rigorously defined sequence. This workflow ensures efficiency, quality, and adherence to your specifications, minimizing delays and cost overruns. The journey begins when you submit your 3D CAD file (STEP, IGES, or native formats preferred) via our online portal. Our integrated system immediately initiates the AI-Powered Quoting Engine. This engine analyzes geometric complexity, material requirements, sheet thickness, feature density, and required secondary operations. It cross-references real-time data on material costs, machine availability, and labor rates to generate an accurate, detailed quotation within hours—not days—providing upfront clarity on cost and lead time without manual intervention.
Following quote acceptance, the project enters the critical Design for Manufacturability (DFM) Analysis phase. Our engineering team conducts a comprehensive review, moving beyond basic feasibility to optimize your design for production. We scrutinize bend radii against material type and thickness, verify minimum hole sizes and spacing relative to sheet gauge, assess flange lengths for tool clearance, and evaluate feature placement to avoid secondary handling. Crucially, we identify potential issues like excessive tight tolerances on non-critical features or impractical grain direction requirements that could cause warpage. This proactive collaboration often involves direct consultation with your design team to suggest minor, non-functional adjustments that significantly enhance manufacturability and reduce costs, preventing costly rework later. DFM sign-off is mandatory before any metal is cut.
With an approved DFM report, the project advances to Production Execution. First, our nesting software optimizes material utilization, strategically arranging parts on the raw sheet to maximize yield and minimize waste. Cutting commences using high-precision fiber laser or turret punch systems, selected based on feature complexity and volume. Subsequent CNC press braking forms bends with exacting angular accuracy, guided by co-developed bend sequences. Secondary operations like welding, hardware insertion, or surface finishing (powder coating, anodizing, plating) follow as specified. Throughout, in-process inspections at key stages—post-cutting, post-bending, pre-finishing—verify dimensional compliance against your drawing using CMMs and optical comparators. Final assembly and 100% first-article inspection ensure the delivered part meets all functional and aesthetic requirements before shipment.
