STAMP KEYCHAIN VS INJECTION KEYCHAIN
2023/01/11
The most common materials of keychain are iron, copper, brass and zinc alloy.
Compared with zinc alloy, the production speed of iron or copper or brass stamp keychain is faster. Most of the time, iron keychain is relatively cheap, and zinc alloy keychain is more expensive. The main reason is the material of zinc alloy is higher. However, when it comes to large size and thick thickness, zinc alloy injection keychain may not be more expensive than iron stamp keychain, and sometimes the same size zinc alloy can be thinner than iron, copper or brass stamp keychain. When the original design pattern is 3D, the zinc alloy die casting method can better meet the customer's design.

However, the thickness of stamp keychain is limited by the material and size, which can not be very thick, generally about 1.5-2.5mm.

And iron stamp keychain is cheaper than copper stamp keychain because iron is cheaper than copper.
