Precision CNC Turning Services for Custom
Metal & Plastic Parts

We ensure high consistency between the first article and batch production through process control, data management, and on-site expertise, rather than relying solely on final inspections.
First Article Inspection (FAI): Once the first piece is processed, we perform a full dimensional inspection to verify critical dimensions, tolerances, and surface finish. Mass production only begins after FAI approval.
In-Process Sampling: During mass production, we conduct periodic dimensional checks according to the production beat, focusing on critical features and geometric tolerances (GD&T).
Precision Instrumentation: We utilize calibrated calipers, micrometers, and CMMs (Coordinate Measuring Machines) to ensure all measurement data is reliable.
Material Uniformity: For batch orders, we unify the material source and can provide material certifications to ensure consistent performance across all units.

Yes. Depending on your requirements, we can provide the following material documentation:
Mill Test Certificate (MTC) / Material Certificate: Detailing the material grade, chemical composition, and mechanical properties.
Material Standards Compliance: Documentation showing adherence to ASTM, EN, JIS, or GB standards.
Batch Consistency Statements: Ensuring all parts in a large order originate from the same material lot.
Note: If your project requires third-party testing or specialized material certifications, please specify this before the quotation stage so we can confirm the lead time and costs.

Yes. We fully support NDA execution and treat customer intellectual property protection as a fundamental engineering principle.
Our specific measures include:
Support for unilateral or mutual NDAs
NDAs can be signed before drawing review or quotation.
Controlled access to technical data
Customer drawings are accessible only to project-related engineering personnel.
No outsourcing or public display
Parts are not used for marketing, sample displays, or third-party demonstrations.
No part retention or replication
Finished parts are not retained or reproduced without written customer authorization.
We understand that for engineering-driven customers, the design itself is the core asset.

We take full responsibility for our machining quality and maintain a transparent, actionable after-sales policy:
Immediate Response: Upon receiving feedback, we respond immediately. If the product is found to be non-conforming due to our error, we will provide a free remake or a full refund.
Corrective Action: We log the issue into our internal process records and perform a root-cause analysis to prevent the recurrence of the issue in future orders.
Solution-Oriented: Our goal is not to deflect responsibility, but to resolve the problem quickly to keep your project on schedule.

Surface Treatment:
If the treatment methods and requirements are clearly defined, they will be listed as a separate line item or integrated into the unit price.
If requirements are unconfirmed, these are not included by default to avoid misunderstandings later.
Logistics Costs:
We offer various Incoterms including EXW, FOB, CIF, and DDP based on your needs.
Shipping costs are typically listed separately to allow for easier cost comparison and accounting.
