This factory floor video shows: (1) our 5,000 sq.m. Bao'an, Shenzhen machining plant with 30+ imported CNC machines; (2) a walkthrough of the 5-axis DMG Mori cell, Swiss-type turning area, Zeiss CMM inspection room, and automated parts cleaning line; (3) the daily morning quality stand-up meeting; (4) a sample end-to-end production flow from material stock → blanking → CNC → deburr → QC → packaging → shipment. The video was shot in Q4 2023 during a regular production day, no staging, so buyers see actual operating conditions. If you would like a live virtual tour focused on a specific process or SKU, contact our sales team to schedule a Zoom call at your convenience.

Suntech operates 30 numerically controlled machines on site plus 38 cold heading and thread rolling machines for fastener production. The CNC fleet includes: 12 3-axis vertical machining centers (VMCs, FANUC / MAZAK, 8,000–12,000 RPM); 6 4-axis horizontal machining centers (HMCs) for rotary tombstone work; 2 5-axis DMG Mori DMU 50 simultaneous mills for complex 3D surfaces; 6 Citizen Cincom Swiss-type lathes (12 mm, 20 mm, 32 mm) with live tooling + sub-spindle; 2 Mazak INTEGREX turn-mill centers for medium-diameter mill-turn work; 2 Studer ID/OD precision grinders. Auxiliary equipment includes 4 Mitsubishi wire EDMs, 1 sinker EDM, vibratory deburr tumblers, and a 6-station ultrasonic cleaning line. A full machine list with serial numbers + calibration dates is available under NDA.

As of 2025, Suntech factory certifications include: (1) ISO 9001:2015 Quality Management System (SGS); (2) IATF 16949:2016 Automotive Quality Management System (TÜV Rheinland) — required for our EV chassis and battery fastener programs; (3) ISO 14001:2015 Environmental Management System; (4) ISO 45001 Occupational Health & Safety. In-house test lab is ISO/IEC 17025 accredited for dimensional, hardness, coating thickness, and salt spray testing. We are also in Stage 2 audit for AS9100D aerospace QMS, expected completion mid-2026. Copies of current certificates are available on the website Resources page, and originals can be verified via the respective accreditation body portals.

Yes — both. In-person visits: welcome by appointment, M–F 9:00–17:00 Shenzhen time; we provide airport pick-up from SZX, factory interpreter (English/Japanese/Korean), catered lunch, and dedicated 2–4 hour technical tour with the plant manager + process engineer assigned to your program. Virtual visits: Zoom or Teams live-stream walkthrough using our factory 360° PTZ cameras + engineer wearing a GoPro to get close-ups on specific machines, setups, or inspection steps — no travel needed, typically 45–60 minutes. For large programs (>US$500K) we also support third-party on-site audits (SGS, BV, TÜV) arranged within 5 business days of request. Email sales@suntech-cn.com to schedule.

Monthly CNC machining capacity: ~30,000 machining hours across 2 shifts × 22 working days = ~1,300 machine-hours per week. In practical SKU terms: (1) Prototyping cell: 500 new part numbers / month, 1–50 pieces each, 3–7 day turnaround; (2) Low volume production: 5,000–30,000 pieces / month mixed SKU; (3) High volume repeat programs: 50,000–200,000 pieces / month (e.g., Swiss-type turned pins). Cold heading fastener capacity: 6 machines × 2 shifts → 8,000,000 standard or custom fasteners per month. MOQs: No MOQ for prototype CNC jobs (even 1 piece is fine). MOQ for dedicated cold header tooling is typically 50,000 pieces per SKU, amortized across the program's 12-month volume.
