The materials engineering team is available Monday through Friday from 8:00 AM to 6:00 PM (GMT-3). Inquiries received outside these hours are answered at the start of the next business day. For production line emergencies, we have a priority channel via email with automatic acknowledgment of receipt.

To expedite the response, we recommend attaching the drawing or sketch with main dimensions, the reference alloy (Zamak 3, ZA-8, ZK-12, or other), the estimated volume per batch, and the required dimensional tolerances. It is also helpful to indicate if the part will be exposed to corrosive environments or cyclic loads.

Yes. The review of physical or digital samples (STEP/IGES files) is completed within 48 business hours from receipt. For die-casting samples, the report includes porosity analysis, Brinell hardness, and dimensional verification against the drawing. If additional tests are required, a meeting with the materials laboratory is coordinated.

The technical library is available on the corporate portal, in the "Resources" section. There you will find alloy datasheets with chemical composition, mechanical properties, and design recommendations. We also publish case studies with production data and rejection rates. If you need a specific document not listed in the library, you can request it through the contact form.

Yes. Our engineers advise on choosing the most suitable alloy based on the service environment, geometric complexity, and production volume. For example, for suspension components exposed to moisture and salts, ZK-12 is recommended, while for decorative parts with a good surface finish, Zamak 5 is preferred. The initial consultation is free of charge.

Samples are shipped through selected carriers with online tracking. Shipping costs are borne by the requester, except for previously agreed-upon joint development projects. To coordinate a pickup or check the status of a shipment, write to logistica@zinkandsons.com or call (89)4170-0114.
