Small batch CNC machining

Significance & Application Scenarios of Small Batch Production

Keywin flexibly aligns production volumes with different development stages—from 10 validation parts to 500-unit small batches—while maintaining consistent manufacturing efficiency and cost control.

Product Development Validation: Verify structural, assembly, and functional feasibility.

Market Testing and Demonstration: Supports small-batch trial sales or sample displays prior to product launch.

Equipment or Component Replacement: Addresses requirements for specialized repair parts, small-batch custom components, or discontinued model accessories.

Low-Demand Products: Ideal for non-mass-produced items such as custom equipment, specialized instruments, and experimental apparatus.

Our Manufacturing Capabilities

CNC Precision Machining

Achieves tolerances as tight as ±0.005 mm, supporting 3/4/5-axis milling and turning.

Multi-Process Small Batches

3D printing, silicone molding, laser cutting, EDM/wire cutting.

Surface Finishing

Anodizing, electroplating, sandblasting, polishing, and more.

Assembly & Delivery

Component assembly, functional testing, and customized packaging.

Process & Quality Control

We maintain a comprehensive quality management system, with experienced teams ensuring product precision and consistency throughout production.

Quality processes include: Incoming Inspection → First Article Inspection (FAI) → Process Sampling → Outgoing Quality Control (OQC). Each step adheres to strict standards, guaranteeing process stability and dimensional consistency.

Equipped with CMM (Coordinate Measuring Machine), projectors, calipers, hardness testers, and other inspection tools, we provide CMM reports, dimensional reports, and full inspection records, ensuring tolerances remain stable within ±0.005–0.01 mm.

We support the development of customized acceptance criteria and inspection plans based on client requirements, delivering full traceability and reliable quality assurance from design to delivery.

FAQ

What is your Minimum Order Quantity (MOQ)?

Our MOQ policy is designed to be as flexible as possible to meet your needs:

CNC Machining: 1–1000 pcs

3D Printing: 1–50 pcs

Silicone Vacuum Casting: 1–100 pcs

Laser Cutting: 1–500 pcs

EDM (Spark Erosion): 1–100 pcs

Wire Cutting: 1–100 pcs
How do I know which manufacturing process is best for my project?

You don’t need to choose the process yourself. Simply share your drawings, 3D files, samples, or even a rough sketch, and our engineers will evaluate the geometry, material, tolerances, and quantity requirements to recommend the most suitable manufacturing process.
What is your production lead time?

For samples: 3-7 days. For mass production: 10-30 days after order confirmation, depending on the order quantity and part complexity. Rush services are available for urgent projects.
What’s your product price?

Small-batch orders don’t follow a fixed pricing model. The cost is determined by your part’s geometry, material, finish, and the required quantity (whether it’s 1 pc or 1000 pcs). Share your drawings or a sample, and we’ll prepare a detailed quotation within 24 hours.
How do you handle quality issues?

If any quality issue is found, we will promptly evaluate the cause and provide corrective, rework, or remake solutions to ensure the parts meet specifications.
Can you sign a Non-Disclosure Agreement (NDA)?

Yes. We strictly protect customers’ intellectual property and design confidentiality, and can sign an NDA to ensure project security. Over the past 20+ years, we have supported numerous companies across OEM/ODM services, helping them bring products from concept to mass production while maintaining strict confidentiality at every stage.
What if I don't have drawings? Can you help?

Of course. We offer ODM (Original Design Manufacturing) services — you can simply provide sketches, photos, or reference samples, and our engineering team will help turn your idea into a manufacturable design.
