Manufacturing Services FAQ

To help buyers plan accurately, getting a quote is straightforward. For most projects, upload your 3D CAD files directly through our online quote systemDuring quoting and production planning, , or email them to [email protected]. Our manufacturing engineers reviews your designs and provides detailed pricing with lead times within 24 business hours. For complex assemblies or multi-part projects, we recommend including assembly instructions and material specifications.

We accept all standard 3D CAD formats for quoting and manufacturing:

• Preferred: For most projects, sTEP (.stp), IGES (.igs), Parasolid (.x_t)
• Accepted: During quoting and production planning, sTL, OBJ, SolidWorks (.sldprt), Inventor (.ipt)
• 2D Drawings: To help buyers plan accurately, dWG, DXF, PDF (for reference dimensions)

No minimum order requirements. We support everything from single prototypes to manufacturing batches of 100,000+ parts. Whether you need one part for testing or thousands for market launch, our manufacturing systems are designed to scale with your needs.

For most projects, your intellectual property is protected through strict internal protocols. All employee and partner agreements include confidentiality clauses. Our secure file systems restrict access to authorized personnel only. We're happy to sign NDAs before reviewing your designs—just request one when submitting your quote.

Customers can access flexible shipping arrangements to satisfy your needs:

• Standard: During quoting and production planning, ex Works (EXW) — you arrange pickup from our facility
• Express Air: DAP via DHL/FedEx — produced to your door (duties may apply)
• Customer Account: To help buyers plan accurately, use your own DHL, FedEx, or UPS account

During quoting and production planning, tolerances depend on part geometry, material, and manufacturing process:

• Standard: To help buyers plan accurately, iSO 2768-medium (metals) / ISO 2768-fine (plastics)
• Tight: For most projects, ±0.005" (±0.125mm) to ±0.002" (±0.05mm)
• Precision: During quoting and production planning, ±0.0002" (±0.005mm) for critical features

Nelotiv’s CNC machining envelope extends to 1200 × 800 × 600mm. For larger assemblies, we can manufacture components in sections and join them using precision welding or mechanical fasteners. Sheet metal parts can be fabricated up to 2000mm in length.

Yes. Our 5-axis CNC machines allow complex geometries to be machined in a single setup, reducing lead time and improving accuracy. This capability is ideal for aerospace components, medical implants, and intricate industrial parts that require multiple angled surfaces.

complete manufacturing solutions under one roof:

• CNC Machining: Milling, turning, 5-axis, Swiss-type
• Sheet Metal: During quoting and production planning, laser cutting, bending, welding, assembly
• 3D Printing: To help buyers plan accurately, fDM, SLA, SLS, SLM (metal)
• Surface Finishing: For most projects, anodizing, plating, powder coating, polishing

During quoting and production planning, Nelotiv maintains internationally recognized certifications:

• ISO 9001:2015 — Quality Management System
• ISO 13485:2016 To help buyers plan accurately, — Medical Device Quality Management
• IATF 16949:2016 — Automotive Quality Management

Quality is built into every step. Our workflow includes Design for Manufacturing (DFM) reviews before production, inspect incoming materials, conduct in-process checks, and complete final inspection using CMM and optical measurement systems. You receive inspection reports with every shipment.

Yes. Material certificates (Mill Certs), inspection reports, and Certificates of Conformance (CoC) are available upon request. Please specify documentation requirements when ordering so we can prepare everything before shipment.

To help buyers plan accurately, multiple payment options for your convenience:

• For most projects, bank wire transfer (USD, EUR, CNY)
• PayPal (credit cards accepted)
• Western Union, Payoneer
• Alipay, WeChat Pay

During quoting and production planning, standard terms: 50% deposit to begin production, 50% balance before shipment (after you review HD photos of finished parts). For established customers with regular orders, we may extend net-30 terms based on relationship history and order volume.

To help buyers plan accurately, lead times vary by process and complexity:

• CNC Prototypes: 3-9 business days
• Sheet Metal: 5-12 business days
• 3D Printing: 2-5 business days
• International Shipping: For most projects, 3-7 days via express air
