The metal casting process is characterized by forcing molten metal under high pressure into a mould cavity. Once the mould cavity is filled, the pressure is maintained until the casting solidifies. Then the mould opens and the buckle is ejected.
Required a skilful craftsman to guarantee the best results. It takes a lot of time but eliminates a shortage of machine deburring.
The buckle is in a vibrating container. The barrel contains a mixture of abrasives and liquids. Those start moving and rubbing against the buckle with the vibratory movement.
This process can create a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface as a result.
With manual or machine to assemble pin to the buckle Or assemble different clip system or twistable system.
Different metal is deposited on a conductive surface.
Under the high-speed turning, wheel leaves the extremely tiny line on the plating layer.
To isolate from the air, the buckle will be coated with a transparent layer.
