Smart hardware,
startup to shipped.

Hardware startups love us because we make quotes and iteration painless. Upload a STEP file, get pricing in 24 hours, iterate until you're ready for production — from investor demo sample to first 1,000-unit run.

How hardware startups use us

Hardware startups are in a different hurry than established OEMs. A typical consumer electronics brand runs a 12-month design cycle; a hardware startup trying to hit a Kickstarter ship date runs a 4-month cycle with three fewer engineers. What they need from a manufacturing partner isn't just speed — it's speed plus manufacturing judgment, because the startup's founding team rarely has the experience to know which DFM rules matter and which are old-wives-tales.

Our typical hardware startup workflow is: weekly iteration cycles on CNC-machined prototypes (3–5 day turns, progressively closer to production intent), a vacuum-cast pre-production batch for Kickstarter backers or investor seeds (50–200 units), and a first production run in injection molding once volume and design are settled.

Investor demo samples and pre-seed hardware

At the earliest stages — before a seed round, before a proper industrial designer is hired — founders need a handful of physical demos to raise money. We produce these without looking down our nose at the low volumes. A set of 5 investor demo units in CNC aluminum, bead-blasted, anodized, and cleanly assembled runs $500–3,000 depending on complexity and turns in 1–2 weeks. See our rapid prototyping page for lead time options.

IoT device enclosures

IoT devices live in a specific manufacturing sweet spot: too low volume for injection molding to make sense at first (often 500–5,000 units across a product's first 12 months), but aesthetically more demanding than industrial IoT gear. The right process for most is vacuum casting — silicone tooling costs 5–10% of injection mold tooling, first parts land in 3 weeks, and the finish quality is indistinguishable from production injection molding on painted parts.

Our vacuum casting cells produce 15–25 parts per silicone mold. For a 200-unit production run, we typically pour 8–15 molds in parallel. Resin chemistry mimics ABS, PC, PMMA, PP, TPU, and flame-retardant grades. For over-molded soft-grip sections, we run two-shot processes on manual presses.

Robotics components

Robotics customers come to us for structural machined parts: frame rails, motor mounts, gearbox housings, joint brackets, end-effector plates. Aluminum 6061-T6 is the default material; 7075-T6 for weight-critical or load-bearing parts; titanium Grade 5 for the top-line wearable robotics and medical exoskeleton projects where the cost premium is acceptable.

For end-of-arm tooling (EOAT) that needs custom geometry matched to a specific workpiece, we run quick-turn 5-axis machining from customer STEP files. Typical turnaround 1 week; typical run size 1–10 units per deployment.

Drone chassis and camera gimbals

Drone work breaks into two types. Consumer quadcopters at high volume are made from injection-molded plastic and carbon-fiber composite — not our sweet spot. Industrial and inspection drones made in lower volumes (50–2,000 units per year) often use machined aluminum airframes and CNC-machined camera gimbals; that's where we fit.

For camera gimbals specifically, we hold tight tolerances on the bearing bores and pivot interfaces (±0.02 mm typical) to ensure smooth stabilization performance. Dynamic balancing is handled by customer's assembly, but we can provide pre-balanced static fixtures on request.

Kickstarter and backer-reward production

If you've launched a hardware Kickstarter, the manufacturing path typically goes: fulfill early backers (first 50–100 units) with CNC'd or vacuum-cast quality parts, move mid-tier backers (100–500 units) to vacuum casting, then move to injection molding for volumes above 500 and stretch-goal reward units.

The mistake we see most often is founders committing to injection molding on day one because it has the lowest per-unit cost at high volume — then realizing they need 6 months of tooling lead time and $40k upfront capital, and can't actually ship until 10 months post-campaign. The staged approach above gets early backers their rewards in 3–4 months and sets up a proven design for injection molding at month 8.

/ FAQ

Frequently asked questions

Q01What's the fastest you can turn a functional prototype?+
72 hours for a straightforward CNC aluminum part (bracket, housing shell, sensor mount) at extra-fast pricing. Standard expedite is 3–5 business days. For vacuum-cast parts that need silicone tooling, minimum 7–10 days. We're honest about lead time at quote — we don't promise 3 days then deliver in 2 weeks.
Q02Can you keep our IP confidential before we file patents?+
Yes. Our standard NDA is signed on first project quote and covers all CAD files, drawings, and communication. CAD is stored in controlled access folders — only assigned engineers see your files. For customers with specific IP concerns (new battery tech, novel mechanical architecture), we sign project-specific IP clauses beyond our standard NDA on request.
Q03We're planning a Kickstarter — can you help us figure out manufacturing before launch?+
Yes, and we recommend doing this before you finalize your funding target. We'll review your CAD, suggest DFM improvements, propose a staged manufacturing path (prototype → vacuum cast pre-production → injection molding), and give you realistic per-unit costs at different volumes. This usually shifts your pricing strategy and stretch-goal planning.
Q04Do you work with hardware accelerators and VC-backed startups?+
Yes, both. We've produced investor demo samples for seed-stage startups and first production runs for Series A and B hardware companies. For accelerator cohorts (HAX, Techstars, YC hardware batch), we can offer batch pricing if multiple teams share material runs. Ask your cohort lead to introduce us.
Q05Can you handle small runs of 20–50 units cost-effectively?+
Yes. For volumes below 100 pieces, CNC from billet is usually the most cost-effective process — no tooling, just machine time. For volumes of 10–100 pieces of complex geometry, vacuum casting with a silicone tool gives production-quality parts at roughly 2–3× per-unit cost of injection molding but with near-zero tooling investment. We help you choose the right path per project.
Q06What about drone chassis and robotics structural parts?+
Drone airframes in 6061-T6 or 7075-T6 aluminum are a regular workflow. For weight-critical robotics (wearable exoskeletons, mobile manipulators), titanium Grade 5 or magnesium AZ31 is a worthwhile upgrade. For high-volume consumer drones, carbon-fiber composite would be the right material — we can CNC machine CFRP plates but for monocoque airframes we'd refer you to a composite specialist.
