Not in the platform sense. At JIZAO, every RFQ is reviewed by real engineers rather than an automatic quoting system. We typically respond within 12 hours, and for standard projects, we can usually provide a feasibility review, optimization suggestions, and quotation within 24 hours after receiving sufficient project information.

Before production, we check the key manufacturing risks in your design and communicate any concerns clearly. After order confirmation, we continue to update you on project progress throughout production. All parts are inspected against the drawing before shipment, and we do not send parts that do not meet dimensional requirements to our customers.

To review your project properly, we recommend sending 3D files or 2D drawings, along with the material, quantity, tolerance requirements, surface finish requirements, and delivery address. The more complete the information, the more accurate our engineering assessment and quotation will be.

Lead time depends on part complexity, quantity, material, and process requirements. Prototype parts are typically shipped within 2–5 days, and for suitable projects, selected parts can be delivered in as fast as 1 day. Low-volume production usually takes around 15–25 days.

For suitable CNC machining projects, tolerances can be controlled as tight as ±0.025 mm (±0.001″). The actual achievable tolerance depends on the material, part size, geometry, feature type, and inspection requirements shown on the drawing.

We support a wide range of metal and plastic materials for CNC machining. We also offer multiple finishing options, including anodizing, powder coating, painting, electroplating, brushing, sandblasting, and polishing. If you have a specific material, finish, color, or appearance requirement, please include it in your RFQ so our engineers can confirm the most suitable solution.

Yes. JIZAO supports rapid prototyping, low-volume production, and batch manufacturing. We help customers choose a practical machining route based on the project stage, quantity, quality requirements, and delivery target.

Yes. These are the types of projects we are especially familiar with. We have strong experience in multi-axis machining, thin-wall parts, difficult-to-machine materials, and complex precision components, especially for aerospace, medical, robotics, and UAV applications.

No strict MOQ is required. We can support single prototype parts, small batches, and repeat production orders. The right manufacturing approach depends on the part design and quantity.

Parts are inspected against the approved drawing requirements before shipment. Our team reviews dimensional and quality requirements throughout the process, and we do not knowingly send nonconforming parts to customers. For projects with specific inspection needs, we can align the inspection method with the order requirements in advance.

Yes. For standard projects, we can provide DFM / manufacturability feedback during the quotation stage. If required, we can also provide documents such as dimensional inspection records, CMM reports, FAI documents, material certificates, RoHS/REACH reports, and third-party inspection documents, depending on the project requirements.
