Make mold (tooling).Sometimes, customer will make a sample mold, which is smaller and cost less, Just for making samples. Sometimes, customer make a big mold directly, for both making samples and mass production.
The mold usually made by steel. We promise the mold can be used for 50000 times in 10 years. If there are some problems during the guarantee period, our company will pay for the repairs or remake.
