Technical Capabilities

Honyo Prototype provides precision laser processing services for both metal and plastic sheet materials. While laser engraving is commonly applied to plastics for marking and surface detailing, the broader capabilities in laser cutting, bending (post-processing), and welding are critical for functional prototyping and low-volume production. Below are the technical specifications and material considerations for laser processing, with a focus on plastics such as ABS and Nylon, and comparative notes for metals like Aluminum and Steel.

Process	Material	Laser Type	Thickness Range	Power Requirement	Tolerance	Edge Quality	Notes
Laser Cutting	ABS	CO₂ Laser	0.5 – 10 mm	30 – 100 W	±0.1 mm	Smooth, slightly melted edge	High precision; minimal post-processing; flammable—requires ventilation
Laser Cutting	Nylon	CO₂ Laser	1 – 12 mm	40 – 120 W	±0.15 mm	Smooth, may show slight browning	Good for gears and insulators; absorbs moisture—pre-dry recommended
Laser Cutting	Aluminum	Fiber Laser	0.8 – 15 mm	500 – 4000 W	±0.2 mm	Clean, oxidized edge	Reflective—requires anti-reflective coating or pulsed mode
Laser Cutting	Steel	Fiber Laser	0.5 – 20 mm	500 – 3000 W	±0.1 mm	Smooth, dross possible on thick cuts	Mild steel cuts efficiently; stainless requires assist gas (N₂/O₂)
Bending	ABS	Not applicable (thermal forming post-cut)	Up to 6 mm	N/A	±0.5° angular	Smooth inner radius	Requires heated bending jig; not laser-bent directly
Bending	Nylon	Not applicable (thermal forming post-cut)	Up to 8 mm	N/A	±0.5° angular	Moderate springback	Preheating to 80–100°C recommended for clean bends
Bending	Aluminum	Press brake (post-laser cut)	0.8 – 6 mm	N/A	±0.2°	Clean, no cracking if grain direction controlled	Laser cutting precedes bending; avoid bending over cut edges
Bending	Steel	Press brake (post-laser cut)	0.5 – 8 mm	N/A	±0.2°	Clean, sharp bend lines	High tensile steels may require annealing prior to bending
Laser Welding	ABS	Diode/Transmission Laser (via through-transmission welding)	1 – 5 mm	50 – 150 W	Joint-dependent	Hermetic, minimal flash	Requires one transparent and one absorptive part; additives may be needed
Laser Welding	Nylon	Diode/Transmission Laser	1 – 6 mm	60 – 200 W	Joint-dependent	Strong, chemically resistant	Excellent for fluid housings; moisture content affects weld strength
Laser Welding	Aluminum	High-power Fiber Laser	0.5 – 8 mm	1000 – 4000 W	±0.1 mm	Deep penetration, spatter possible	Requires shielding gas (Ar/He); high reflectivity and thermal conductivity challenges
Laser Welding	Steel	Fiber Laser	0.5 – 12 mm	500 – 3000 W	±0.1 mm	High strength, low distortion	Ideal for structural joints; stainless benefits from nitrogen shielding

Notes on Process Compatibility
Laser engraving of plastics (ABS, Nylon) is typically performed using CO₂ lasers (10.6 μm wavelength) due to high absorption rates. Engraving depth can be controlled via power and speed adjustments, typically ranging from 0.05 mm to 1.5 mm. For ABS, engraving produces high-contrast marks with minimal charring when parameters are optimized. Nylon engraves well but may require marking additives for enhanced contrast.

Laser cutting of plastics achieves tight tolerances and is ideal for intricate geometries. However, thermal effects such as melting and recast layers must be managed through assist gas (e.g., compressed air for plastics, inert gas for metals).

Welding of plastics via laser transmission welding (LTW) is a non-contact, precise method suitable for medical and automotive sensors. Metals require high-energy fiber lasers, with joint design and surface preparation being critical for weld integrity.

All processes are supported by CNC-controlled systems at Honyo Prototype, ensuring repeatability and integration across hybrid material assemblies.

From CAD to Part: The Process

Honyo Prototype executes laser engraving of plastic sheets through a rigorously controlled five-stage workflow designed for precision, speed, and manufacturability assurance. This integrated process minimizes errors and ensures optimal results for engineering thermoplastics.

CAD Upload and Material Specification
Clients initiate the process by uploading native CAD files (STEP, IGES, or native CAD formats preferred) via our secure portal. Concurrently, the required plastic sheet material, grade, thickness, and finish must be specified. Our system validates file integrity and identifies critical engraving features such as line widths, depth requirements, and text height. Material selection is critical at this stage as it directly impacts laser parameters and feasibility.

AI-Powered Quoting and Feasibility Assessment
Our proprietary AI engine analyzes the CAD geometry against Honyo’s extensive material database and laser processing rules. The quote generated within minutes includes not only cost and lead time but also preliminary feasibility flags. Key parameters evaluated include minimum feature size relative to material type, thermal sensitivity thresholds, and potential for edge charring or melting. The AI cross-references historical production data for similar materials like acrylic, polycarbonate, ABS, or polyimide to predict optimal laser power, speed, and frequency settings. Example material considerations include:

Material Type	Key Laser Parameter Considerations	Common Applications
Acrylic (PMMA)	Low power, high speed; minimal charring risk	Displays, signage, lenses
Polycarbonate (PC)	Moderate power; requires assist gas to prevent yellowing	Enclosures, automotive parts
ABS	Lower power settings; high risk of melting	Prototypes, housings
Polyimide (Kapton)	Precise pulse control; sensitive to overscanning	Flexible circuits, insulation

Engineering DFM Review
Every job undergoes mandatory Design for Manufacturability (DFM) analysis by Honyo’s senior manufacturing engineers. This step validates the AI’s preliminary assessment and addresses nuanced technical constraints. Engineers verify engraving depth consistency across complex geometries, assess thermal distortion risks for thin sheets, and confirm minimum feature resolution aligns with material properties. Critical checks include evaluating whether fine text or intricate logos will vaporize rather than engrave cleanly on the specified plastic. Clients receive a formal DFM report with actionable recommendations—such as adjusting line widths or suggesting alternative materials—before proceeding to production. No job advances without explicit DFM sign-off.

Precision Laser Engraving Production
Approved jobs move to production using Class 4 fiber lasers with 10–50 W power ranges, selected based on material and depth requirements. Plastic sheets are fixtured under inert gas (typically nitrogen) to prevent oxidation and melting artifacts. Our CNC-controlled systems execute engraving paths with ±0.025 mm positional accuracy, dynamically adjusting pulse duration and spot size per the pre-validated parameters. In-process metrology checks occur at 30% and 70% job completion to verify depth consistency and edge quality. All operations adhere to ISO 9001 environmental controls, maintaining temperature and humidity stability to prevent material warpage.

Quality-Controlled Delivery
Post-engraving, each sheet undergoes 100% visual inspection under calibrated lighting for debris, incomplete vaporization, or surface damage. Dimensional verification uses coordinate measuring machines (CMM) for critical features. Cleaned parts are packaged in anti-static, non-abrasive materials with humidity control for sensitive polymers. Delivery includes a traceability report documenting laser parameters, inspection results, and material lot numbers. Standard lead time is 3–5 business days from DFM approval, with real-time production tracking available via client portal. Rush services achieve 24-hour turnaround for qualified geometries and materials.
