General Questions

Q1: What industries do you focus on for precision manufacturing?

A: We specialize in the robotics and optical communications industries, providing custom precision components tailored to their strict requirements.

Our quality control process includes:

  • Incoming material inspection
  • In-process inspection
  • Final inspection (100% or sampling)
  • Measuring tools such as calipers, micrometers, projectors, and CMMs

Inspection reports can be provided for critical dimensions.

Q2: What is your minimum order quantity (MOQ) for custom components?

A: Our MOQ is flexible—starting from 1 piece for prototyping, scaling seamlessly to mass production based on your needs.

Q3: Do you provide design and engineering support for custom projects?

A: Yes. Our experienced engineers offer DFM reviews, custom component design, and optimization to meet your project’s specific needs.

Precision & Quality Control

Q1: Why Choose US for Optical Industry parts with tight tolerances?

A: Our standard CNC machining tolerance is ±0.01 mm. For critical features such as bearing seats, precision holes, and shafts, we can achieve tolerances down to ±0.005 mm, depending on part design and material.

Certified quality & compliance: ISO 9001 and ISO 13485 certifications ensure all optical components meet rigorous standards for precision and structural integrity.

Ultra-high precision machining: Our CNC technology achieves tolerances as tight as ±1μm, meeting the extreme accuracy required for laser systems and optical assemblies.

Rapid prototyping to production: We offer a seamless transition from prototypes to low-volume production, ensuring fast design validation and efficient scaling.

Bespoke engineering & tooling: We provide fully customizable solutions with tailored design and specialized tooling for unique optical requirements.

Instant AI quoting & DFM: Upload files for instant quotes and automated DFM feedback to optimize your optical parts before production begins.

50% faster lead times: By integrating digital quoting with high-speed manufacturing, we reduce lead times by over 50% to accelerate your time-to-market.

Q2: How do you ensure consistent quality for mass production?

A: We implement strict quality control throughout production, using advanced testing equipment to ensure consistent quality across all batches.

We ensure batch-to-batch consistency through:

  • Standardized machining processes
  • Dedicated fixtures and tooling
  • First Article Inspection (FAI)
  • In-process and final inspections

This helps ensure smooth robot assembly and stable product quality.

Q3: Do you provide material traceability?

A: Yes. We offer full material traceability, including certificates and test reports, to meet industry compliance requirements.

Surface Finishes

Q1: What surface finish options do you offer for robotics and optical components?

A: We provide one-stop surface finishing services, including:

  • Anodizing (standard, hard anodizing, multiple colors)
  • Sandblasting
  • Powder coating & painting
  • Electroplating
  • Black oxide
  • Polishing and brushing

We pay special attention to color and finish consistency across batches, which is critical for robot assembly.

Q2: Which surface finish is best for optical communications components?

A: Polishing (for ultra-smooth surfaces to avoid light interference) and Anodizing (for corrosion resistance) are most recommended for optical components.

NPI & Production

Q1: How long does prototype production take?

A: Prototypes take 2-7 business days, depending on component complexity and surface finish requirements.

  • Prototypes: 3–7 working days
  • Small batch production: 4–7 working days
  • Mass production: Depends on quantity and complexity

Urgent projects can be prioritized upon request.

Q2: Can you support end-to-end NPI solutions?

A: Yes. We offer full NPI support—from concept design and prototyping to mass production scaling.

With years of experience in robot CNC machining know-how:

  • Robot assembly requirements
  • Critical tolerance control
  • Appearance and finish consistency
  • Fast iteration and validation cycles

Many customers choose us for reliability and first-time-right results, not just price.

Logistics & Support

Q1: Do you ship internationally?

A: Yes, we ship globally, with mass production lead times of 10-20 business days and expedited options available.

Q2: What’s your lead time for small-batch production?

A:  Small batches (50–500 units) of automotive parts with fast delivery.
Prototypes: Ready in 24 hours (e.g., 3D-printed plastic dashboards, CNC-machined aluminum brackets).


Small batches: Delivered in 5–7 days for most parts (e.g., stamped body panels, 5-axis machined engine components).
