QWhat zinc alloy materials do you use for die-casting?
We primarily use Zamak 3 (ZnAl4Cu0.1) and Zamak 5 (ZnAl4Cu1) in compliance with ASTM B86 standards. These materials offer an excellent balance of strength, dimensional stability, and surface finish quality.
QWhat surface finishing options are available?
We offer a wide range of surface treatments including polishing, electroplating (nickel, chrome, zinc), powder coating, spray painting, and PVD coating. Custom colors and finishes are all available upon request.
QDo you support OEM and ODM orders?
Yes, we fully support both OEM and ODM services. We provide CAD/3D modeling assistance, DFM analysis, rapid prototyping within 5–7 working days, and high-precision mold manufacturing.
QWhat is your salt spray test performance standard?
Our standard plating thickness ensures a minimum of 240 hours neutral salt spray test. For higher requirements, we can customize products to exceed 480 hours. Our specs: Cu ≥ 15μm, Ni ≥ 10μm, Cr ≥ 0.15μm.
QWhat is the typical lead time for production?
Prototypes and samples are typically delivered within 5–7 working days. Bulk production lead times vary depending on order complexity and quantity.
QWhat quality control measures are in place?
We are ISO 9001:2015 certified and implement strict QC throughout the entire process—from mold making to final inspection. Our QC includes 100% dimensional inspection and SPC process control.
