Developing functional prototypes quickly is essential for reducing product development cycles and accelerating time-to-market. At Hongming Sheng, we specialize in high-precision sheet metal prototyping — from single samples to low-volume production — helping engineers validate designs before scaling.

✔ Clarify Design Requirements

Before prototyping begins, ensure every detail of your drawing is finalized. Dimensions, tolerances, bend radii, hole positioning, and functional constraints must all be clearly defined. If design adjustments are possible, we can offer manufacturability suggestions to avoid costly trial and error.

✔ Choose the Right Material

Select materials based on your application's strength, flexibility, corrosion resistance, and finish requirements. Common options include stainless steel, aluminum, brass, or copper. Need help deciding? Our engineers can recommend suitable materials for forming or welding performance.

✔ Use CAD & Unfolding Software

CAD software enables accurate flat pattern generation, bend allowance simulation, and rapid file transfer to machines. Send us 2D or 3D CAD files (STEP/DXF) — our team ensures proper unfolding and prepares it for CNC laser cutting or punching.

✔ Understand Forming Limitations

Consider the limitations of your chosen forming process — press brake, deep draw, or progressive die. Keep bend radii ≥ material thickness and allow sufficient clearance between holes and bends. Our DFM team helps refine designs for clean, crack-free bends.

✔ Plan for Tolerance Stack-up

When assembling multiple parts, accumulated tolerances can cause misalignment. By incorporating datum points, tabs, or alignment pins, you reduce assembly risk and ensure consistent fitment. Let us help you review and optimize assembly tolerances.

✔ Utilize Rapid Prototyping Techniques

For faster validation, we combine CNC machining, laser cutting, and manual forming in-house. We can deliver sheet metal prototypes within 2–5 days. Optional finishing services include powder coating, anodizing, silk-screening, and spot welding — all in one stop.

Whether you're refining your first sample or need short-run production, our prototyping services ensure speed, precision, and cost control. Share your drawings or sketches with us and get feedback within 24 hours.

Non-Disclosure Agreement

Hongming Sheng always respects intellectual property rights. We do not share product drawings, models, or process details with any third party without written approval. NDA agreements are fully supported to ensure confidentiality throughout your prototyping and production process.
