Technical Capabilities

Sheet metal dome fabrication involves precision manufacturing processes including laser cutting, bending, and welding to produce structural or enclosure components. The selection of materials such as Aluminum, Steel, ABS, and Nylon significantly influences the feasibility and methodology of each process. Below is a technical specification summary for each process based on material compatibility and standard industry practices.

Process	Material	Thickness Range	Tolerances	Surface Finish Considerations	Notes
Laser Cutting	Aluminum	0.5 mm – 12 mm	±0.1 mm	Smooth edge, minimal dross; may require deburring	Highly suitable; reflective nature managed with appropriate laser settings
	Steel (Mild)	0.8 mm – 20 mm	±0.1 mm	Oxide layer possible; post-process cleaning advised	Excellent compatibility; high precision and edge quality
	ABS	1 mm – 6 mm	±0.2 mm	Melted, sealed edges; slight charring possible	Limited use; typically not recommended for structural domes
	Nylon	1 mm – 6 mm	±0.2 mm	Melted edges with thermal distortion risk	Not ideal for laser cutting due to poor heat resistance
Bending	Aluminum	0.5 mm – 10 mm	±0.2° angular, ±0.1 mm	Smooth finish; risk of surface marking	Requires controlled V-die and tooling to prevent cracking
	Steel (Mild)	0.8 mm – 15 mm	±0.2° angular, ±0.1 mm	Minimal deformation with proper tooling	Excellent bendability; springback must be compensated
	ABS	Not recommended	N/A	High risk of cracking under stress	Thermoplastic behavior makes cold bending impractical
	Nylon	Not recommended	N/A	Poor form stability and high elasticity	Not suitable for standard press brake forming
Welding	Aluminum	≥2 mm typical	±0.5 mm alignment	Requires post-weld finishing; oxidation possible	TIG or MIG preferred; needs shielding gas and skilled technique
	Steel (Mild)	≥1 mm typical	±0.5 mm alignment	Spatter possible; grindable to smooth finish	Highly weldable; commonly done with MIG or spot welding
	ABS	Not applicable	N/A	Solvent or ultrasonic welding only	Not compatible with arc or laser welding; limited structural integrity
	Nylon	Not applicable	N/A	Limited to hot-plate or vibration welding	Not suitable for metal-based welding processes

General Observations
Laser cutting is highly effective for Aluminum and Steel sheet metal domes, providing tight tolerances and clean edges. Bending operations are standard for metals but not feasible for ABS and Nylon due to their thermoplastic nature and low yield strength under forming stress. Welding is structurally viable only for Aluminum and Steel, with process selection dependent on joint design and environmental requirements. ABS and Nylon domes are typically fabricated via molding or additive manufacturing rather than sheet metal techniques.

From CAD to Part: The Process

Honyo Prototype executes sheet metal dome fabrication through a rigorously controlled five-stage workflow optimized for precision domes requiring deep drawing, stretch forming, or hydroforming. This process ensures geometric accuracy, material integrity, and on-time delivery for complex curved components.

CAD Upload
Customers initiate the process by uploading native 3D CAD files (STEP, IPT, SLDPRT, or Parasolid formats) via our secure customer portal. For dome geometries, we specifically validate surface continuity, draft angles, and minimum radius-to-thickness ratios against material capabilities. Our system automatically checks for manufacturability thresholds such as a minimum dome height-to-diameter ratio of 0.15 and maximum depth limitations based on material ductility.

AI Quote Generation
Within 90 minutes, our AI-powered quoting engine analyzes the dome geometry against 12,000+ historical production datasets. It calculates cost drivers unique to domes: deep-draw tooling complexity (progressive vs. compound dies), material waste factors for circular blanks, and required press tonnage (typically 300–1,200 tons for diameters 50–500mm). The quote includes explicit allowances for springback compensation and secondary operations like flange trimming or edge rolling, with material utilization efficiency metrics provided.

DFM Analysis
All dome designs undergo mandatory Design for Manufacturability review by our tooling engineers. Key dome-specific checks include:

DFM Parameter	Critical Threshold	Action if Violated
Wall thickness reduction	>25% of original	Redesign dome profile or recommend alternative material
Grain direction alignment	Not radial to dome apex	Mandate blank orientation specification
Minimum radius	<8x material thickness	Propose multi-stage forming sequence
Springback prediction	>0.5° angular deviation	Integrate CNC radius compensation in tool path

This phase includes FEA simulation of material flow during forming to prevent wrinkling or tearing, with tolerance stack-up analysis for critical spherical radii (±0.1mm achievable).

Production Execution
Approved designs move to production using our dedicated dome fabrication cell:
Blanking: Laser cutting of circular blanks with 0.05mm positional accuracy
Forming: Hydraulic presses (500–1,200 ton capacity) with CNC-controlled draw depth and blank holder force; domes >200mm diameter use hydroforming for uniform wall thickness
Secondary Operations: In-die flange curling, precision grinding of sealing surfaces, and automated deburring
In-Process Verification: First-article inspection of dome profile using coordinate measuring machines with 3D surface deviation mapping against CAD nominal

Delivery and Certification
Final domes undergo comprehensive quality validation before shipment:
Full FAI report per AS9102 with spherical radius measurements at 8 azimuthal points
Material certification traceable to mill test reports
Dimensional inspection package including wall thickness mapping at crown, mid-radius, and flange zones
Protective packaging with custom foam inserts preventing deflection during transit
Standard lead time from CAD approval to delivery is 12–18 days for quantities ≤500 units, with expedited 7-day options for critical applications. All deliverables include digital quality records accessible via customer portal.
