Complete CNC Manufacturing Solutions for OEM and ODM Projects
Most CNC manufacturing shops simply run parts based on provided drawings. A true solution involves understanding your actual problem, not just your geometry. Since 2003, we've evolved from a small workshop to operating 50+ CNC machining centers across two factories with 632 employees, continuously learning from every project.
What defines a manufacturing solution? First, identifying potential issues before production begins. Second, handling the full range of processes under one management system. Third, understanding industry-specific standards and requirements.
Key Features
  • Full-Process Capability: CNC turning, milling (3/4/5-axis), wire EDM, surface grinding, surface treatment, and assembly with single-point contact
  • Multi-Material Machining: Aluminum, stainless steel, titanium, copper, brass, carbon steel, and engineering plastics with 48-hour material availability
  • Prototype to Volume: 1 piece in 3-7 days for validation, 100-1,000 pieces in 7-15 days, 10,000+ pieces in 15-25 days with consistent quality
  • Certified Quality System: ISO 9001:2015, IATF 16949, RoHS, CE, REACH with CMM inspection and PPAP support
  • Engineering Support: Free DFM review, material selection guidance, tolerance optimization, and manufacturability analysis

Frequently Asked Questions
What file formats do you accept?
STEP, IGES, SolidWorks, Pro/E, AutoCAD, PDF - STEP is preferred for 3D parts. PDF works for 2D drawings, and even hand sketches can be quoted.
Can you handle confidential designs?
Yes, we sign NDAs before receiving drawings and maintain strict IP protection with secure systems and document deletion upon request.
What's the difference between your prototype and production service?
Same quality system and inspection criteria. Prototypes use standard tooling (3-7 days), while production uses dedicated fixtures and optimized processes (7-25 days).
Do you support PPAP for automotive parts?
Yes, we provide PPAP Level 1-3 support with Design FMEA, Process FMEA, Control Plans, MSA studies, and SPC data per IATF 16949 requirements.
How do you handle engineering changes mid-production?
We assess impact, provide change order quotes within 24 hours, and often absorb minor changes to maintain project momentum.
What's your on-time delivery rate?
96% across all orders in 2025, with delays primarily due to material supply issues or customer-induced changes.
