DESC:FIELD
The present disclosure relates to a method for manufacturing a metal bangle.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.

Metal such as gold has been the most preferred precious metal used for making jewellery for ages, considering the fact that some metals such as gold are valuable, does not corrode and are sustainable. It is of utmost desirability that the jewellery such as a bangle made of metal mainly of gold is flawless and polished so that it is not mistaken for fake gold. Further, intricate designs are created on the outer surface of the bangle to make it more beautiful, thereby adding to its appeal. The process of producing gold bangles is either made by hand or by means of a machine. Hand-made bangles, although display uniqueness and intricacies, can lack perfection, shape and quality and show visible variations. Any minor defect, caused by human error, can cause the bangle to lose its charm and therefore value. On the other hand, machine made bangles are more consistent in shape and quality, but often fall short of the uniqueness that is quite often desired by a customer.

There is therefore felt a need for a method for making a metal bangle, while alleviating the aforementioned drawbacks.

The present disclosure envisages a method for manufacturing a metal bangle to enhance the consistency in shape and quality of the bangle The present disclosure provides creates unique and intricate designs of fine quality on the bangle. The present disclosure will now be described in detail with reference to Figure 1 through Figure 2.
Referring to Figure 1, the method (100) for manufacturing a metal bangle includes the following steps:
Step 101: Preparing a metal alloy
The method (100) includes preparing a metal alloy of a pre-desired composition and purity in a controlled environment to achieve the desired properties of the metal bangle.
In an embodiment, metal alloy is selected from the group of elements consisting of gold, silver, steel, platinum and copper.
For Example- The desired metal alloy for manufacturing metal bangles is considered to be 22kt gold alloy, especially to achieve spring-like characteristics in the metal bangle. Accordingly, gold is melted and mixed with other suitable elements to obtain an alloy of a pre-desired composition and purity in a controlled environment to achieve the desired springiness in the gold.
Step 102: Casting the prepared alloy
This step includes casting the prepared alloy, by a casting machine, into a circular tube.
In an embodiment the prepared alloy is introduced in its molten form in a casting machine. The casting machine facilitates the moulding of the alloy into a circular tube having a desired configuration, wherein the tube has a predetermined diameter and thickness. Casting the alloy into a tubular configuration ensures precision and quality in the tube production.
In an embodiment, the desired configuration of the spiral hollow tube is either an oval or circular configuration.
Step 103: Drawing the cast tube
This step includes drawing the formed cast tube, through a set of dies of progressively reduced diameter, to reduce the diameter of the circular tube.
In an embodiment, the cast tube is passed through a tube drawing machine which allows a reduction in the thickness of the tube, while simultaneously enhancing its spring action.
In an embodiment, the tube is repeatedly drawn through progressively smaller dies to reduce the diameter of the circular tube to a desired dimension and spring properties.
Step 104: Twisting the Circular Tube
This step includes twisting the circular tube, by a CNC machine, to obtain a spiral bangle. The twisting is done with the help of an end mill tool.
Step 105: Creating a design
This step includes creating a design, by the CNC machine, on an operative external surface of the obtained spiral metal bangle.
In an embodiment, intricate and precise designs are created on the external surface of the bangle with the help of a CNC machine. Employing the CNC machines to create the designs, allows customization of the designs while adding to its aesthetic appeal and uniqueness.
Step 106: Turning the bangle
This step includes turning of the bangle, by a lathe machine, to facilitate finishing of an operative interior surface of the bangle.
In an embodiment, the bangle (200) is turned in a lathe machine to facilitate smooth and precise finishing on the interior surface of the bangle, while enhancing comfort and aesthetics.
In an embodiment, the desired configuration of the metal bangle (200) has an arcuate cross-section.
Step 107: Polishing
This step includes polishing the operative outer and inner surfaces of the bangle by a polishing tool.
In an embodiment, polishing includes a sub-step of filling any gaps formed on the operative outer and inner surfaces of the bangle.
In an embodiment, polishing includes a sub-step of cleaning the bangle to remove impurities therefrom.
Figure 2 illustrates an isometric view of the bangle. The bangle (200) made by the above-mentioned process, has a spiral configuration defined by multiple turns (210) and end tips (205A, 205B), thereby giving the illusion that a wearer is wearing multiple individual bangles.
In an embodiment, the method further ensures polishing evenly throughout the inner and outer surface of the bangle (200), thus adding to the appeal of the bangle (200).
In an embodiment, the method of the present disclosure can be used for making a bangle (200) of any desired material and desired configuration as per the requirements of the customer. Additionally, the designs on the bangle can be customized as per the requirements of the customer.
In an embodiment, the bangle (200) is not only unique and covered with intricate designs, but also has a consistent quality.
In an exemplary embodiment, the method of the present disclosure is used for making a metal bangle (200) of 22kt gold having a spiral configuration defined by a plurality of helical turns (210) and a pair of end tips (205A, 205B) as shown in Figure 1 and Figure 2.

Individual components of a particular embodiment are generally not limited to that particular embodiment, but, are interchangeable. Such variations are not to be regarded as a departure from the present disclosure, and all such modifications are considered to be within the scope of the present disclosure.
