Factory-direct CNC machining and rapid prototyping services for small-to-medium production runs and one-off samples. The supplier works with copper, brass, stainless steel, aluminum and various alloys, offers wire-EDM, broaching and micro-machining, and supports custom surface finishes and packaging. Minimum order quantity is 10 pieces and common CAD formats (PDF/DWG/STEP/IGES) are accepted for quoting and tooling.
Services: CNC turning, milling, wire EDM, broaching, drilling, laser machining, chemical etching, rapid prototyping.
Materials: Copper, brass, bronze, stainless steel, aluminum, hardened metals, steel alloys, plastic (on request).
Certifications: ISO 9001:2015 and ISO 13485:2016 (suitable for regulated/medical device supply chains).
File formats accepted: PDF, DWG, STEP, IGES.
MOQ: 10 pieces.
Typical lead times: 14–30 days depending on complexity and quantity; supplier lists example lead times (1–3,000 pcs ≈ 16 days; 3,001–10,000 pcs ≈ 30 days; larger volumes negotiable).
Equipment highlights: HAAS, CITIZEN, TSUGAMI, Miyano (precision CNC brands).
Pricing tiers (example from supplier): 1–999 pcs: ~$0.50/unit; 1,000–9,999 pcs: ~$0.30/unit; ≥10,000 pcs: ~$0.15/unit (final price depends on drawing/spec).
Factory-direct savings — pricing without middlemen, useful for startups and small manufacturers.
Low MOQ + fast prototyping — minimum of 10 pieces and rapid turnaround enable quick design validation.
Broad metal capabilities — from soft copper to hardened steels and micro-machining for small, tight-tolerance components.
Regulatory readiness — ISO 9001 & ISO 13485 certifications support medical and regulated applications.
Customization available — optional logo, packaging or mold customizations, and multiple surface treatments (polishing or “as-custom”).
Small mechanical components for consumer electronics, toys and trophies (e.g., doll/trophy parts).
Prototype and low-volume production runs for HVAC, lighting, or decorative metalwork.
Medical device components and precision parts that require certified manufacturing processes.
Precision connectors, bushings, or custom fasteners produced by wire-EDM or micro-machining.
Demand for quick, low-volume metal prototyping is rising as hardware startups compress product development cycles; services that combine low MOQ, rapid turnaround, and ISO compliance are well positioned.
Increased use of copper and brass in precision connectors and decorative parts (because of conductivity and appearance) keeps wire-EDM and specialized machining in demand.
As OEMs pursue localized supply chains, transparent lead times and factory-direct pricing become competitive advantages for contract manufacturers.
