Bolts and nuts galvanizing classes of manufacturing plus procedures
We talk about bolts and nuts galvanizing as one of the galvanization types that follow immersion, when the pieces that need to be galvanized are small, like accessory nails, bolts, washers, nuts or just particularly shaped objects. Generally, bolts and nuts are subjected to the same chemical cleaning treatments as other artifacts, then immersed in galvanizing baths placed inside perforated baskets.
Once the phase of the galvanizing process is concluded, the basket gets transported into the centrifuge with the task of eliminating any excess coating.This process causes the partial removal of the top zinc layer, giving the items’ surface a more matte appearance, and an excellent dimensional accuracy.
Gimeco srl is able to provide fully automated plants to enforce such galvanization types on smallware. We mainly offer automatic centrifuges that perform their cycle above the molten metal bath, greatly increasing the product’s quality and considerably reducing any potential losses. We also supply some hybrid solutions that allow to treat all kinds of hardware, from bolts & nuts to main metalworks, using the same pre-treatment vats and furnaces, depending on our customers’ particular needs.
