FAQ

We support New Product Introduction (NPI). Before mass production, we can provide prototype tooling or small-batch trial runs to verify the design. If design changes are needed, our team can quickly modify the mold or adjust CNC machining parameters to ensure the final part meets your assembly requirements.

As a dedicated contract manufacturer, we respect your Intellectual Property (IP). Once you pay for the custom tooling, the mold belongs entirely to you. We maintain the molds in our factory for your exclusive production use and will never use your proprietary designs for other clients or our own brand.

Yes. If you need to reproduce legacy parts or upgrade plastic components to aluminum, we can perform reverse engineering based on your physical samples. We use 3D scanning to generate CAD data and develop new die-casting molds to replicate the part with precise geometric tolerances.

Yes, Feiya offers a one-stop solution. We have an in-house tooling workshop capable of independent mold design and manufacturing. We utilize Mold Flow Analysis to optimize gate locations and cooling channels before cutting steel, ensuring high-density castings for complex parts like cylinder heads and pump housings.

To provide an accurate quotation, please provide 2D drawings (PDF) with tolerance specifications and 3D models (STEP/IGES/X_T format). Please also specify the aluminum alloy grade (e.g., ADC12, A356), estimated annual quantity, and surface treatment requirements. Our engineering team will conduct a DFM (Design for Manufacturing) review upon receipt.

We are flexible. For mass production of die-cast parts, typical MOQs start from 500-1,000 pieces to ensure cost-efficiency. However, we understand the needs of high-mix, low-volume projects and can support smaller batches during the initial launch phase to help you ramp up.

The cycle from mold design to sample delivery is approximately 60-90 days.

The inner packaging is a standard cardboard box, and the outer packaging is a custom-made wooden box.

We offer flexible export logistics solutions based on your timeline and budget. We can ship via Sea Freight (FCL/LCL) for bulk cost-efficiency or Air Freight for urgent sample delivery. We are familiar with major incoterms like FOB (Ningbo/Shanghai), CIF, and DDP to support global delivery.

We stand behind our quality. If any non-conforming parts due to manufacturing defects (such as casting porosity or dimensional deviation) are found upon receipt, please contact us within 30 days. We will investigate the root cause and provide free replacements or credit in the next shipment to ensure your production is not disrupted.

Our quality lab is equipped with advanced Hexagon CMM (Coordinate Measuring Machines). We verify key geometric tolerances, such as flatness, concentricity, and hole positions, to ensure your CNC machined parts fit perfectly on your assembly line.

Yes. For critical components like engine cylinder heads, fuel dispenser pumps, and valve bodies, we conduct 100% pneumatic leak testing (air-decay test) and pressure testing. This guarantees the parts are free from porosity and leakage before they leave our factory.

We strictly control material quality. Before casting, every batch of molten aluminum is analyzed using a Spectrometer to verify the chemical composition (e.g., Si, Cu, Fe content). We can provide Material Composition Reports with every shipment to ensure compliance with standards like ADC12 or A356.
