Manufacturing Overview
Xunbanglong operates a 15,000-square-meter precision manufacturing facility in Shenzhen, China, housing dedicated CNC machining, sheet metal fabrication, and assembly cells. We provide custom-to-print mechanical components for industrial original equipment manufacturers (OEMs). Our production floor integrates automated material loading, multi-axis machining centers, and a temperature-controlled metrology laboratory to maintain batch-to-batch dimensional stability.
Plant Footprint: 15,000 m² production and assembly area.
Engineering Staff: 28 toolmakers and DFM (Design for Manufacturing) mechanical engineers.
Annual Output: Over 1.2 million precision metal and plastic components shipped globally.
Quality Management System: ISO 9001:2015 certified (Certificate No. available upon request).

Product Development & R&D
Every production order undergoes a structured DFM review before G-code generation to verify geometric feasibility and material suitability.
CAD/CAM Compatibility: Direct processing of STEP, IGES, SolidWorks (.sldprt), and Parasolid (.x_t) files via Mastercam and Siemens NX.
Prototyping Lead Time: Quick-turn CNC prototypes delivered within 3 to 5 business days upon drawing confirmation.
DFM Feedback Protocol: Engineering reports generated within 24 hours to highlight undercuts, thin walls, draft angles, and potential tool clearance risks prior to tool path programming.
Production Capabilities & Technical Parameters
We accommodate complex geometries and difficult-to-machine engineering alloys under controlled machining tolerances.
Achievable Dimensional Tolerances: Standard milling ± 0.01 mm; high-precision milling up to ± 0.005 mm.
Supported Materials:
- Metals: Aluminum (6061-T6, 7075-T6, 5052), Stainless Steel (304, 316L, 17-4PH), Carbon Steel (1045, 4140), Brass, Copper, Grade 5 Titanium.
- Engineering Plastics: POM (Delrin), PEEK, PTFE, Nylon, ABS, Polycarbonate (PC).
Machining Envelope:
- CNC Milling: Up to 1500 × 800 × 600 mm.
- CNC Turning: Up to dia. 400 × 1000 mm.
Manufacturing Process Routing
Our shop floor routing follows a standardized, closed-loop workflow to track component lineage and minimize operational variance:
Incoming Material Verification: Spectrometer material composition check and ultrasonic testing for internal inclusion detection.
Raw Material Preparation: High-speed automatic saw cutting and CNC blank facing.
Primary & Secondary Machining: Multi-axis roughing, stress-relief heat treatment (when specified), and finish contouring.
Deburring & Surface Treatment: Manual precision deburring followed by chemical passivation, anodizing, or powder coating as specified in drawing notes.
Final Quality Audit: CMM dimensional scanning and visual surface inspection against approved client drawings.
Export Packaging: VCI anti-rust wrapping and shock-absorbing crate packing.
Quality Control & Inspection Equipment
Quality verification is integrated into every production milestone rather than left to final sorting. The quality department operates independently from the production scheduling team.
Inspection Instrumentation:
- Hexagon Coordinate Measuring Machines (CMM)
- Keyence optical image dimension measurement systems
- Digital height gauges, thread plug gauges, and micro-meters.
Traceability: Heat number tracking for raw metal blocks; individual inspection sheets and Material Test Reports (MTRs) archived digitally for a minimum of 5 years.
Inspection Checkpoints: 100% First-Article Inspection (FAI) for new part setups, in-process SPC (Statistical Process Control) every 50 parts, and AQL 1.0/2.5 final sampling before shipping.
Production Capacity & Standard Lead Times
We balance multi-shift manufacturing capacity with structured scheduling to meet target delivery schedules.
Operating Schedule
3 shifts daily, with 24/7 automated machining cells for high-volume repeat runs.
OEE Control
Maintained above 85% via scheduled preventive maintenance programs.
Standard Lead Times
CNC Prototypes (1–10 pcs): 5 to 7 business days.
Batch Production (100–5,000 pcs): 15 to 25 business days (subject to material availability and finishing requirements).
Packaging & Order Fulfillment
Protecting machined surfaces during international transit is managed through engineered packaging standards.
Packaging Specifications: VCI (Volatile Corrosion Inhibitor) anti-rust polyethylene bags, custom high-density EPE foam cutouts, and ISPM 15 compliant heat-treated fumigated wooden crates.
Logistics Channels: Express air freight (DHL/FedEx/UPS) for prototypes; ocean freight (FOB/CIF container loading) from Shenzhen/Guangzhou ports for bulk orders.
OEM & ODM Manufacturing Support
We protect client intellectual property and maintain transparent communication channels throughout project execution.
IP Security: Bilateral Non-Disclosure Agreements (NDAs) executed prior to drawing exchange; isolated CAD networks with restricted data export access.
Project Management: Designated project engineers assigned to provide weekly progress logs and verification photo/video documentation upon request.
