- Copper CNC parts and silver CNC parts: These materials are prone to oxidation and can become soft, so we use custom blister boxes, foam packaging, and paper wrapping to protect them during transport.
- Aluminum CNC parts: These parts can easily become scratched, so we use foam packaging and paper wrapping to prevent damage.
- Titanium parts: These parts require protection during polishing, so we use foam packaging and paper wrapping to ensure they arrive in perfect condition.
- Iron and steel parts: We use PP bag packaging and apply anti-rust oil to prevent oxidation and maintain their condition during transport.
- Stainless steel CNC parts and brass CNC parts: We use PP bag and custom boxes or foam inserts, depending on the size and shape of the parts.
We use proper packaging to protect your metal parts during transport. Contact us for any questions about our packaging solutions.
