Compatible Materials

We support a broad range of thermoplastics and metals, optimized for dimensional stability and performance under load. Key materials include:

Metals:
Aluminum: 6061-T6, 7075-T6, 2024-T3 – ideal for lightweight, high-strength components
Steel: 1018, 4140, 4340 – used in high-wear or structural applications

Engineering Plastics:
ABS (Acrylonitrile Butadiene Styrene) – good impact resistance, machinability, and surface finish
Nylon (PA 6, PA 66) – excellent wear and chemical resistance; suitable for moving parts

All plastic machining operations are performed with optimized feeds, speeds, and tool paths to minimize thermal deformation and maintain tight tolerances. Our CNC programs are verified using CAM simulation software (e.g., Mastercam, Fusion 360) to ensure accuracy and repeatability.

From CAD to Part: The Process

Honyo Prototype executes precision plastic machining through a rigorously defined workflow optimized for speed, quality, and manufacturability. Our process begins with secure digital intake and concludes with certified delivery, ensuring seamless transition from concept to functional component. Below is the detailed sequence:

CAD Upload
Clients initiate the process via Honyo’s encrypted online portal, uploading native or neutral CAD formats (STEP, IGES, Parasolid, SLDPRT). The system performs automated validation for file integrity and geometric completeness, confirming unit consistency and absence of non-manifold edges. This stage establishes the foundational geometry for all downstream operations, with immediate confirmation of receipt and preliminary file assessment.

AI-Powered Quoting
Uploaded geometry undergoes rapid analysis by Honyo’s proprietary AI engine, which evaluates dimensional complexity, feature density, and material requirements against live machine capacity and material stock databases. The system generates a preliminary cost and lead time estimate within 15 minutes, incorporating real-time factors such as polymer grade availability (e.g., PEEK, Acetal, Ultem), machine hourly rates, and secondary operation needs. Crucially, all AI outputs are validated by our engineering team to ensure contextual accuracy—addressing nuances like cosmetic finish requirements or tolerance stack-ups that algorithms may overlook.

Engineering-Led DFM Review
Following quote acceptance, our manufacturing engineers conduct a comprehensive Design for Manufacturability (DFM) assessment focused explicitly on plastic machining challenges. This phase identifies risks such as thin-wall deformation, thermal stress points, or non-optimal tool engagement angles unique to polymeric materials. Key considerations include:

DFM Factor	Plastic-Specific Risk	Honyo Mitigation
Wall Thickness	Warpage during cooling	Recommend ribbing or uniform cross-sections
Undercuts	Tool access limitations	Propose split features or alternative toolpaths
Tight Tolerances	Material creep (e.g., Nylon)	Adjust tolerances or suggest stabilized grades
Surface Finish	Melt fracture at high feeds	Optimize spindle speed/feed per polymer type

The engineering team collaborates directly with the client to resolve conflicts, providing annotated CAD markups and alternative geometry suggestions. This iterative step typically reduces production iterations by 65% and prevents costly post-machining rework.

Precision Production
Approved designs move to Honyo’s climate-controlled machining floor, where CNC mills (3- and 5-axis) and lathes process virgin engineering plastics under strict environmental parameters. Critical protocols include:
Material preconditioning to 23°C ±1°C to minimize thermal expansion
Dedicated tooling libraries with sharp, polished carbide cutters to prevent melting
In-process CMM verification at defined checkpoints for features below ±0.025mm
Cleanroom protocols for medical/aerospace components (ISO Class 7)

All operations adhere to AS9100 and ISO 13485 standards, with real-time machine data logged for traceability. Secondary operations like threading, polishing, or bonding occur in specialized workcells with polymer-specific process controls.

Certified Delivery
Final components undergo first-article inspection per AS9102 or client-specific protocols, with full dimensional reports and material certifications packaged with the shipment. Honyo ships via tracked logistics with anti-static and moisture-barrier packaging tailored to polymer sensitivity. Every delivery includes a digital quality dossier accessible through our client portal, containing inspection data, process parameters, and environmental logs. Typical lead times range from 5 to 15 business days depending on complexity, with expedited options available for critical path items.

This integrated workflow ensures plastic components meet stringent functional requirements while minimizing time-to-part—turning digital designs into certified, production-ready hardware with engineering rigor at every phase.
