While hot dip galvanizing is a standard metal treatment method, spin galvanizing is essential for galvanizing small pieces. Read on to see what spin galvanizing is, how it works, and the benefits it offers.
Spin galvanizing is a process used to coat small metal parts with zinc. It is beneficial for covering small, complex parts that may be difficult to dip into a galvanizing bath. The process involves placing the pieces in a basket, which is then submerged in molten zinc, withdrawn, and spun at high speeds. Spin galvanizing increases the lifespan of steel by making it more robust, durable, and rust-resistant.
Spin galvanizing involves several steps. First, the parts that need treating are cleaned and prepared for galvanizing, which removes dirt, grease, or other contaminants by using a method such as shot blasting.
Next, the parts are dipped in a basket into molten zinc. The basket stops the pieces from being lost in the bath. Once a zinc/alloy layer forms, the basket is withdrawn and spun at high speeds. The spinning action distributes the zinc evenly over all parts and removes any excess, creating a uniform coating. The coated parts are removed from the basket and inspected to ensure the coating is even and defects-free.
Spin galvanizing has numerous distinct benefits:
Protect small pieces: One of the main benefits of spin galvanizing is that small parts can be galvanized without being dipped directly into a bath. You gain the benefits of hot dip galvanizing without losing any pieces. This makes it an ideal solution for protecting fasteners, fixings, hinges, and chains.
Increased durability: Unlike surface-level coatings such as paint, the zinc layer used with galvanizing chemically bonds to the metal, making it stronger against corrosion. The zinc coating is also thicker than alternatives, further contributing to its durability. The increased durability enhances the metals lifespan, saving you time and money on repeated coatings.
Environmentally friendly: Galvanizing produces less waste than other methods, using only the amount of zinc needed. This makes it a circular economy environmentally friendly option.
Save money: You can expect to see a greater return on investment with spin galvanizing. Spin galvanizing makes the metal more durable, reducing the frequency of maintenance needed and reducing the associated labour costs such as transportation. It is also a fast process with a short turnaround time, so the parts are returned to you quicker.
Spin galvanizing is an optimal solution for safeguarding small metal parts, providing a combination of cost-effectiveness, efficiency, and environmental friendliness. This method improves adhesion and consistent coverage and minimises material wastage. Unlike alternative steel protection techniques, spin galvanizing stands out for its ability to deliver superior results. By choosing this method, you can effectively shield your small metal pieces.
