Ordering & Delivery FAQ

Please upload your 3D CAD files (STEP, X_T, IGES) and 2D drawings (PDF, DWG) via our quote form. 3D files are used for pricing and programming, while 2D drawings are required to specify tolerances, threads, and surface finishes. We typically quote within 2-8 hours.

Yes. Every quote includes a complimentary DFM review. Our engineers analyze your design for manufacturability issues (thin walls, undercuts, sharp corners) and suggest modifications to reduce cost and risk.

No. We strictly have No MOQ. We support the entire product lifecycle, from 1 single prototype to 10,000+ production parts.

While bots are fast, they often reject complex parts. Boona uses a “Human-Centric” review process. Our expert engineers personally review your files to find creative ways to manufacture complex geometries that automated systems might flag as “impossible.”

Absolutely. We conform to strict international IP protection standards. We are happy to sign a Non-Disclosure Agreement (NDA). Your files are encrypted and never shared with third parties.

• 3D Printing: 1-3 days.

• CNC Machining: 3-5 days (Prototype), 10-15 days (Production).

• Sheet Metal: 5-7 days.

• Vacuum Casting: 10-12 days.

• Injection Molding: 2-5 weeks (T1 Sample).

Yes. If you don’t have CAD files, you can send us the physical part. We offer 3D Scanning and Reverse Engineering services to create the 3D data needed for manufacturing.

Yes. We install Helicoils, inserts, O-rings, and assemble multi-component products. We can also apply custom labels and barcoding.

We follow ISO 2768-m (Medium).

• Metals: ±0.1mm (±0.004″).

• Plastics: ±0.05mm – ±0.1mm.

• High Precision: We can achieve ±0.005mm – ±0.01mm for critical features (like bearing bores) if specified on your 2D drawing.

• 3-Axis: Good for simple flat parts.

• 5-Axis: The cutter moves on X, Y, Z, A, B axes simultaneously. Essential for complex organic shapes (impellers) and machining 5 sides of a part in a single setup to maintain high positional accuracy.

CNC tools are round (rotating). We cannot machine a sharp 90° internal corner. There will always be a radius equal to the tool radius.

• Design Tip: Add a fillet radius or use a “Dog-bone” relief if a square part needs to fit inside.

• 6061-T6: Standard choice. Weldable, corrosion-resistant. Good for enclosures.

• 7075-T6: “Aerospace grade.” High strength (comparable to steel) and hardness. Hard to weld. Good for high-stress gears and shafts.

• As-Machined: Ra 1.6 – 3.2μm (Visible tool marks).

• Smooth Machined: Ra 0.8 – 1.6μm.

• Polished: Ra < 0.4μm (Mirror finish).

• Optical Polish: Ra < 0.05μm (Diamond polish).

Yes. We machine Stainless Steel (17-4PH, 316L), Titanium (Ti-6Al-4V), Inconel 718, and Tool Steel.

• Milling: 2000 x 800 x 600 mm.

• Turning: Diameter up to 500 mm.

es. We support standard metric (M) and imperial (UNC/UNF) threads. We also install Helicoil inserts for stronger threads in soft metals (Aluminum/Magnesium).

• SLA (Resin): High detail, smooth surface. Best for visual prototypes.

• SLS (Nylon Powder): Strong, functional parts without support structures.

• MJF (HP Multi Jet Fusion): Best for low-volume production of functional Nylon PA12 parts.

• DMLS (Metal): For complex metal geometries.

• SLA: Naturally watertight.

• SLS/MJF: Inherently porous. To make them watertight/airtight, we offer Vapor Smoothing or epoxy infiltration.

• Prototyping (FDM/SLA): Focus on fit and form. Parts may be anisotropic (weaker in Z-axis).

• Production (SLS/MJF/DMLS): Focus on strength. Parts are isotropic (strong in all directions), comparable to injection molding.

We do not recommend printing threads directly as they are brittle. We recommend designing pilot holes and letting us tap them manually, or using Heat-Set Inserts.

• SLA: 0.05 – 0.10 mm.

• SLS/MJF: 0.08 – 0.12 mm.

• DMLS: 0.02 – 0.06 mm.

Yes. Vapor smoothing (for SLS/MJF) chemically melts the outer surface to seal pores, creating a smooth, glossy, watertight finish similar to injection molding.

You do. Once you pay for the tooling, it is your property. We store and maintain it for free at our facility for its lifetime.

• Rapid (Soft) Tooling: Aluminum/P20 Steel. Life: 5k-10k shots. Lead time: 15 days.

• Production (Hard) Tooling: NAK80/H13 Steel. Life: 100k-1M+ shots. Lead time: 4-6 weeks.

Draft angles (1°-2°) allow the part to eject from the mold without dragging.

• Rule: Add 1.5° draft for every 0.025mm (0.001″) depth of texture (VDI 3400).

Follow the 60% Rule: Ribs and bosses should be max 60% of the main wall thickness. Use Coring to maintain uniform wall thickness.

• Overmolding: Molding soft rubber (TPE) over a hard plastic substrate (e.g., tool handles).

• Insert Molding: Molding plastic around a metal insert (e.g., brass nut).

• SPI A-1/A-2: High Gloss.

• SPI B-1/B-2: Semi-Gloss.

• SPI C-1/C-2: Matte.

• MT / VDI 3400: Textured (Spark Erosion).

Yes. A family mold produces multiple different parts (e.g., top and bottom enclosure) in one shot to save tooling costs. Note: Parts should be of similar size and material.

Typically ±0.005″ per inch (±0.125mm per 25mm). Tighter tolerances depend on material shrinkage rates.

 It is the perfect “bridge” for 20-100 units. It delivers production-like quality (color, texture, rubber hardness) without the high cost of metal molds.

One silicone mold typically lasts for 15-20 shots before dimensions degrade. For 100 parts, we make 5 molds.

Yes. We mix pigments into the PU resin to match any Pantone (PMS) or RAL color exactly.

We use PU resins simulating production plastics:

• ABS-like (PX-200)

• PC-like (Clear, PX-5210)

• Rubber-like (TPE/TPU, Shore A 30-90)

• PP-like (High impact)

We usually use SLA 3D Printing or CNC Machining to create the master pattern, which is then hand-polished to the desired finish before making the silicone mold.

The K-Factor is the ratio of the neutral axis to material thickness, used to calculate the Flat Pattern. We calculate this automatically; you just provide the folded 3D model.

Generally 1x Material Thickness (1T).

• Aluminum: 1T.

• Steel: 1T.

• Stainless: 1.5T. Going smaller risks cracking the material.

Holes should be at least 2.5x Material Thickness + Bend Radius away from the bend line to prevent distortion (ovalization).

• Powder Coating: Durable, decorative.

• Anodizing: (Aluminum only).

• Zinc Plating: Corrosion resistance for steel.

• Silk Screening: Logos and labels.

• PEM Insert Installation: Press-fit nuts and studs.

• Laser Cutting: For precision and complex shapes.

• Water Jet: For thick materials or materials sensitive to heat.

• NCT Punching: For simple holes and louvers in high volume.

• Type II (Standard): Adds ~5-10μm (0.0002″-0.0004″). Usually negligible for general tolerances.

• Type III (Hard): Adds ~25-50μm (0.001″-0.002″). This significantly affects dimensions and holes may need masking.

• Anodizing: Chemical integration with the metal. Thin, metallic look. Only for Aluminum/Titanium.

• Powder Coating: A sprayed plastic layer baked on. Thick (~80μm), durable, hides surface defects. Applicable to any metal.

Passivation is a chemical process for Stainless Steel. It removes free iron from the surface to enhance corrosion resistance without changing the part’s dimensions or appearance.
