Methods Of Inspection Of Screws
- Jul 30, 2018 -

Screw surface inspection is divided into two kinds, one is the screw after the production is not electroplating before the test, the other is a screw plating after the test, that is, screw hardening, screw surface after the inspection. Before the screw is produced, we inspect the screws for dimensions, tolerances and so on. See if it meets the national standards or customer requirements. After the screw surface treatment, we electroplating good screws for inspection, the main test plating color and there are no bad screws.

In this way we send screw goods to customers, customers receive goods to smooth clearance.
