What We Can Help

Focus on CNC milling, CNC turning, Swiss turning, 3D printing, and rapid prototyping. We serve Automotive, Electronics, Optics, Medical and more.

We offer a fast, efficient, end-to-end solution for your machining projects—handling prototype to small-batch runs.

Why Choose Us

Incredible Capabilities

From prototype to production with robust capacity.

On-time Delivery

We provide a practical schedule for your project.

Exceptional Experience

Responsive support with engineering assistance.

How's Our Capability

Advanced equipment including 3-axis, 4-axis, and 5-axis CNC with tight tolerance control down to ±0.005 mm.

Process control ensures every step meets requirements. CMM provides inspection reports quickly.

Quality Assurance

ISO Certified Manufacturer Our approach strictly follows the ISO 9001 quality management system with standardized processes, calibrated equipment, and traceable documentation to guarantee consistent quality at every stage.
  • Part design checking and feasibility review
  • Material incoming inspection with certification verification
  • First Article Inspection (FAI) for critical projects
  • In-process inspection with SPC (Statistical Process Control)
  • Final quality inspection with detailed reports
  • Export package inspection to ensure safe global delivery
  • Tool and equipment calibration on a scheduled basis
  • Non-destructive testing (NDT) when required
  • Continuous operator training and qualification
  • Documented corrective and preventive action (CAPA) system

About MTSPi CNC

Precision CNC Machining Partner for Prototypes and Production Parts

MTSPi CNC, operated by MEITESI, supports overseas buyers with CNC milling, CNC turning, Swiss-type machining, mill-turn machining, rapid prototyping, and surface finishing from Shenzhen, China. The goal is simple: make custom metal and plastic parts easier to quote, easier to inspect, and easier to reorder.

Engineering-first quoting

We review drawings, 3D CAD, material requirements, tolerances, surface finish, threads, and assembly risks before confirming the machining route.

Prototype to low-volume production

One-off samples, bridge production, and repeat batches can be managed with practical fixture planning and documented process control.

Inspection-ready parts

Dimensional checks, thread gauges, surface finish checks, CMM inspection, and first article reports can be arranged around your project requirements.

How We Work

A Clear Manufacturing Workflow for Custom CNC Parts

  1. RFQ reviewDrawings, 3D files, material, quantity, finish, tolerance notes, and delivery needs are checked before quoting.
  2. DFM feedbackWe flag sharp internal corners, deep pockets, thin walls, tight tolerance risks, and post-finish dimensional concerns.
  3. Machining and process controlTooling, fixture strategy, datum control, and in-process inspection are matched to part geometry.
  4. Final inspection and packingParts are checked, protected, labeled, and packed according to shipping and cosmetic requirements.
