A Complete Guide to Traditional, Modern & Technology-Driven Bangle Making

Gold bangles are one of the most iconic pieces of jewelry across cultures. From classic handcrafted kada designs to modern CNC-finished bangles, each style carries its own identity — and each requires a different manufacturing technique.

Whether you are a jewelry lover, a retailer, or part of the gold manufacturing industry, this guide explains the most popular types of gold bangles and how every style comes to life inside the workshop.

✨ Why Understanding Bangle Types Matters

Every bangle differs in:

• Production time

• Manufacturing technique

• Strength & durability

• Design complexity

• Weight & gold wastage

Knowing these helps customers choose better and helps jewelers explain craftsmanship more effectively.

1. Solid Bangles — The Classic & Timeless Style

What Are Solid Bangles?

Solid gold bangles are made from a continuous circle of gold with no hollow space inside. They are durable, long-lasting, and traditional.

How They Are Manufactured

• Gold is melted and cast into rods.

• Rods are rolled to the required thickness.

• Craftsmen bend the rod into a circular shape.

• The ends are welded using torch or laser welding.

• Final shaping, sizing, and polishing complete the piece.

Best For: Bridal sets, premium collections, traditional wear.

2. Hollow Bangles — Lightweight & Budget-Friendly

What Are Hollow Bangles?

Hollow bangles look solid but are empty inside. They offer bold designs with much lighter weight.

Manufacturing Process

• Thin gold sheets are rolled into tubes.

• Tubes are shaped into bangles using forming machines.

• Precision welding seals the tube perfectly.

• CNC or laser machines may add external patterns.

• Final polishing gives a shiny, finished look.

Best For: Daily wear, fashion collections, gifting.

3. Casting Bangles — Bold, Detailed & Artistic

What Are Casting Bangles?

These bangles are made through the casting process, allowing complex shapes, textures, and artistic details.

How They Are Manufactured

• Designers create a 3D CAD model.

• The model is printed in wax.

• Wax tree is created for mass production.

• Investment casting forms a mold.

• Molten gold is poured inside.

• After cooling, the mold is broken, and the bangle emerges.

• Filing, soldering, finishing, and polishing are done manually.

Best For: Designer bangles, textured patterns, stone-studded styles.

4. CNC Bangles — Precision Cut & Modern Luxury

What Are CNC Bangles?

CNC (Computer Numerical Control) bangles feature sharp, geometric, and diamond-cut-like patterns created by machines.

Manufacturing Method

• Start with a solid or hollow tube.

• CNC machine cuts micro-designs with extreme precision.

• Multi-axis movement creates 3D and 4D patterns.

• Laser finishing enhances shine and sharp edges.

Best For: Modern, stylish bangles with brilliant sparkling effects.

5. Laser-Welded Bangles — Seamless & Highly Durable

What Makes These Special?

Laser welding creates invisible joints, increasing strength and providing a clean, flawless finish.

Manufacturing Steps

• Components are made separately (body, edges, joints).

• High-precision laser welding joins them.

• This avoids excess heat and prevents damage.

• Final polishing ensures no visible seam or line.

Best For: High-quality premium bangles, especially openable bangles.

6. Openable Bangles — Practical & Stylish

What Are They?

These bangles come with a hinge and lock system, making them easy to wear and remove.

How They Are Manufactured

• Bangle is crafted in two halves (casting or CNC).

• Hinges and locks are made separately using micro-components.

• Laser welding is used to assemble fine parts.

• Final checking ensures lock strength and smooth movement.

Best For: Daily wear bangles, elderly customers, bridal pieces.

7. Kada Bangles — Thick, Bold & Cultural

What Is a Kada?

A kada is a thicker, often wider bangle, sometimes for men, designed with heavy patterns or plain finishes.

Manufacturing Technique

• Created using forging, rolling, or casting.

• Heavy polishing tools give a smooth or hammered finish.

• Sometimes laser engraving or CNC detailing is added.

Best For: Traditional wear, men’s jewelry, temple-style designs.

8. Flexible Bangles — Smooth, Comfortable & Trendy

What Are Flexible Bangles?

Made with multiple small joints or wires, flexible bangles easily adjust to wrist movement.

Manufacturing Process

• Thin wires or micro-links are crafted individually.

• Each link is laser-welded or joined with precision.

• Gold tubes and springs may be used for flexibility.

• Polishing and cleaning complete the piece.

Best For: Modern fashion jewelry, lightweight collections.

9. Textured Bangles — Matte, Hammered, Gloss & More

What Makes Them Unique?

Textures enhance personality using surface design.

How They Are Made

• Matte by sanding or blasting

• Gloss by high-speed polishing

• Hammered by hand tools

• CNC by machine engraving

Best For: Stylish women, gifting, designer collections.

✨ Final Thoughts: Choosing the Right Bangle Style

Each type reflects a different blend of craftsmanship and technology. Understanding these makes it easier to choose the right bangle — whether for retail, manufacturing, or personal style.
