Welcome to the Zhaohao FAQ center. Here you will find quick, reliable, and transparent answers regarding our custom spring production, precision CNC machining capabilities, IATF 16949 quality controls, and lead times. We are dedicated to providing global B2B clients and partners with the clear insights needed for seamless project collaboration.
A: We specialize in custom spring manufacturing (compression, flat, and hardware springs) and precision machining services. Our capabilities include CNC machining, Swiss-type CNC lathe machining, turn-mill multitasking, automatic lathe machining, metal stamping, and cold heading.
A: Yes, absolutely. We provide fast and precise prototyping (samples) to help you verify your designs. Our advanced facilities are fully equipped to support both rapid prototyping and subsequent high-volume mass production.
A: For customized loose parts and low-volume orders, we operate on a "Sample-to-Batch" phased pricing model. We first quote and produce samples for your approval, and then provide tiered batch pricing based on the finalized design and quantity of each subsequent batch.
A: Because of the setup and calibration costs required for precision hardware machining, small-batch or loose-part orders may not always have the absolute lowest price in the market. However, every small batch is manufactured using the same advanced machinery and undergoes the exact same rigorous quality control as our large-scale production. We prioritize uncompromising quality over low-cost compromises.
A: We prioritize reliability over cheap rates. Unlike low-cost suppliers who compromise on quality for small runs, we apply our strict, automotive-grade IATF 16949 standards to every order. With Zhaohao, you invest in guaranteed precision and peace of mind.
A: We do not have a rigid, one-size-fits-all MOQ. Our MOQ depends entirely on the complexity of the part, the material, and the manufacturing process (e.g., CNC vs. high-volume automatic lathe). Please contact our team with your drawings for a customized assessment.
A:
Prototypes/Samples: Typically 3 to 7 working days, depending on design complexity.
Mass Production: Typically 2 to 4 weeks, depending on order volume and machining processes. We will provide a specific timeline with your quotation.
A: Yes. Upon request, we provide full quality documentation, including Material Certificates (SGS/RoHS), Dimensional Inspection Reports, and First Article Inspection (FAI) reports.
A: We maintain a zero-defect policy. Our facilities are fully IATF 16949 certified (automotive-grade quality management). We also utilize an in-house quality control lab and an advanced CCD visual sorting workshop with over 60 testing instruments to ensure **** precision and consistency.
A: We accept most standard 3D and 2D CAD formats, including STEP (.stp, .step), IGES (.igs), SolidWorks (.sldprt), AutoCAD (.dwg, .dxf), and PDF. If you only have a physical sample, our engineering team can reverse-engineer it to create the drawings for you.
