CNC Machining & Injection Molding — DFM/Moldflow Support, CMM Inspection, Prototype to Production Solutions.
Company Profile
A buyer-ready snapshot for internal review: who we are, what we run, and how we control quality—structured for fast scanning and easy screenshots.
All values are typical ranges. Final tolerance and timing are confirmed after DFM review and measurement plan lock-in.
Capabilities
Pick a path based on your part type and risk profile—then go deeper on the service page for process details and typical applications.
Complex housings and multi-face features in one setup.
Best for: complex housings, optical mounts, and multi-face features that need tight true position across multiple datums.
Learn MoreMicro shafts, pins, and precision fasteners with tight runout.
Best for: micro shafts, pins, and precision fasteners where runout and surface finish make or break assembly.
Learn MoreFrom bridge tooling to production molds with documented trials.
Best for: plastic parts moving from pilot builds to stable volume—where texture, color, marking, and repeatability must match spec.
Learn MoreShorter tool lead times for fast iteration and pilot runs.
Best for: bridge-to-production programs when you need tooling speed without losing measurement discipline and process control.

Capability Summary
Built for buyers who need measurable outcomes: documented inspection, controlled processes, and a faster path from DFM to stable production.
We avoid generic claims—these are the deliverables and controls you can audit.
CMM-backed verification and reportable results on defined features—so critical dimensions stay stable from prototypes to production lots.
Up to ±0.002 mm validation (defined features)Risk-driven planning and CTQ control to reduce variation and improve lot-to-lot consistency across repeat orders.
FMEA · Control Plans · SPC on CTQsOne team closes the DFM loop faster and aligns sampling, trials, and documentation to support production readiness and PPAP-style packages.

We keep this section buyer-scannable: one line on what we typically build, plus a direct path to the dedicated industry page.
Titanium and Inconel brackets, optical mounts, and fasteners with documented measurement on critical features.
See Aerospace CNC MachiningRepeatable CNC parts for EV and powertrain programs—built around CTQ control, traceability, and stable lot-to-lot output.
See Automotive CNC MachiningPrecision housings, brackets, and functional components where documented inspection and clean packaging discipline matter.
See Medical CNC MachiningCosmetic + functional parts that need clean edges, controlled surfaces, and fast iteration from prototype to pilot runs.

Company Profile Modules
A buyer-friendly “snapshot” format: tables and bullets designed for quick internal review, screenshots, and forwarding—without long paragraphs.
| CNC Machining | DMG MORI, HAAS, Makino — 3–5 axis precision machining (±0.005 mm typical). |
|---|---|
| Swiss-Type Turning | Citizen, Tsugami — micro-threaded / high-runout-control components (±0.01 mm typical). |
| Injection Molding | 50–1200T electric/hydraulic machines; multi-shot, LSR, hot runner molds. |
| Additive Manufacturing | EOS 3D printing (metal & polymer): titanium alloys, stainless steel, engineering plastics. |
| Auxiliary Processes | Wire EDM, EDM, grinding, heat treatment, anodizing/plating/spraying/sandblasting. |
Keep the numbers program-specific: final Cpk/CTQ definitions and reporting scope are confirmed during engineering review.
| Certifications | ISO 9001:2015 & IATF 16949 certified; pursuing ISO 13485 (medical) and AS9100 (aerospace). |
|---|---|
| Inspection Devices | Hexagon CMM, Nikon vision system, contour & roughness tester, hardness testers, ceramic gauges. |
| Traceability | Incoming inspection → FAI → in-process checks → final measurement; barcode tracking throughout. |
Documentation packages (FAI/CMM, material/finish certs, lot labels) are aligned to your RFQ and control plan.
