Healing Singing Bowls is a Nepal-based singing bowl manufacturer and wholesale supplier. Our core HSB collections are made through a coordinated production network in Kathmandu Valley, combining specialist metal casting, hand hammering, decorative finishing, acoustic selection and export preparation.
Our hammering workshop is located in Bungamati, a traditional craft area in Lalitpur, south of central Kathmandu. Other specialist stages take place in Balaju, Swayambhunath and our Kathmandu warehouse network. This means that every operation is entrusted to a team with the appropriate equipment and experience rather than forcing the entire process into one building.
For buyers searching for a singing bowl factory in Nepal, this distinction matters. The HSB model is built around a transparent and traceable production process. We coordinate the stages, define the product requirements and inspect the finished bowls before they are prepared for international customers.
One Production Process, Several Specialist Locations
An HSB singing bowl travels through several stages within Kathmandu Valley:
- Balaju — alloy preparation and casting: the metal is melted and cast into thick circular discs.
- Bungamati — heating and hand hammering: the discs are repeatedly heated, hammered and gradually formed into bowls.
- Swayambhunath — specialist finishes: separate teams apply patinas, traditional decoration, etching, laser engraving and selected custom designs.
- Kathmandu — final selection and quality control: finished stock is returned to our warehouse network for visual checks, sound control and note selection when required.
- Balaju — export packing: approved products are protectively packed at our export facility before being transferred to Kathmandu airport.
This structure gives HSB access to specialised skills at every stage while maintaining a consistent commercial and quality-control process.
Why Hammering Begins Before Sunrise
Work at the Bungamati hammering workshop often begins at around 3 a.m.
There are two practical reasons. First, the temperature is cooler, making intense physical work beside the furnaces more manageable. Second, before sunrise, experienced metalworkers can see the colour and glow of the heated bronze more clearly. The red intensity of the metal helps them judge its condition and decide when it is ready for another hammering cycle.
This is not a ceremonial detail created for visitors. It is part of the working rhythm of a demanding hot-metal process.
The Hammering Teams and the Master Craftsman
A hammering group generally includes three to five people. During busy production periods, two or three teams may work in parallel.
Each group is led by an experienced master craftsman who controls the process from the first heating cycles to the final form. The master organises the hammering rhythm, monitors the temperature, checks how the metal is responding and directs the other team members. Diameter, wall height, curvature, thickness and rim regularity are assessed progressively as the bowl takes shape.
The handcrafted singing bowl sector relies on a mobile community of skilled metalworkers from Nepal and West Bengal, India. Teams may rotate between workshops and manufacturers according to production cycles, order volumes and the needs of different projects. This mobility is a normal feature of the regional metalworking ecosystem. Within each production group, an experienced craftsman remains responsible for coordination and technical control.
From Bronze Disc to Hand-Hammered Bowl
1. Preparing and casting the alloy in Balaju
For the classic HSB ranges, the base is a high-tin bronze composed mainly of approximately 80% copper and 20% tin. Five other metals traditionally associated with “seven-metal” bowls may be present only in trace or very small proportions. They should not be understood as seven equal ingredients.
The alloy is melted and cast into circular metal discs in Balaju. The cooled discs are then transported to Bungamati for forming.
This composition describes the standard HSB base. It does not describe every artisan collection distributed by HSB, as other makers may use their own alloy specifications. Read our guide explaining what seven-metal singing bowls actually contain.
2. Heating and collective hammering in Bungamati
The metal discs are heated until they become red and sufficiently malleable. The artisans then hammer them in a coordinated rhythm under the direction of the master craftsman.
As the bronze cools, it becomes harder to work and must return to the furnace. The team repeats the same cycle as many times as necessary:
Heating → Hammering → Reheating → Hammering
Through these successive cycles, a flat disc gradually becomes a bowl. The team adjusts its diameter, height, curvature, wall thickness, base and rim. Large formats require greater metal mass, longer heating cycles and especially careful coordination. Our article on how large and giant singing bowls are made explains this demanding process in more detail.
3. Rim finishing, surface cleaning and sanding
Once the main shape has been achieved, a mechanical finishing tool or lathe is used to regularise the rim. The surface is then scraped to remove black residues and excess material left by repeated heating. A final sanding stage removes rough areas and prepares the bowl for its natural finish, patina or decoration.
Handmade does not mean that every operation is performed without tools. The defining form of the bowl is created through repeated hand hammering; appropriate tools are then used for accuracy, safety and surface preparation.
Patinas, Carving and Laser Engraving in Swayambhunath
Decorative finishing is handled separately by specialist teams, mainly in the Swayambhunath area. Depending on the collection or customer project, this work may include:
- aged patinas and colour treatments;
- shallow hand carving and etching;
- traditional symbols and inscriptions;
- detailed laser engraving for Super Fine Carved bowls;
- logos, names and private-label designs.
The 7 Metal, Patinated, Carved, Super Fine Carved and Sun Moon Black collections share the same principal HSB bowl base. Their main difference is the visual finish. HSB does not claim that patina or engraving automatically improves sound quality.

Visual and Acoustic Quality Control in Kathmandu
After production and finishing, bowls are returned to HSB’s warehouse network in Kathmandu. Our team checks their general condition, form, finish and sound before they move to export preparation.
For orders placed by size, the bowl is checked against the requested size range. A bowl sold as 18 cm must measure between 18.0 and 18.9 cm and is not supplied below the ordered size.
For orders placed by musical note, selection is based on the bowl’s fundamental frequency, never on an overtone. The standard reference is A4 = 440 Hz, while selection using A4 = 432 Hz can be arranged separately. HSB accepts a deviation strictly below 3% from the target fundamental frequency, and the measuring tools are regularly compared for consistency.
Not every bowl sold by size is assigned a precise musical note. Frequency selection is a dedicated service for customers ordering singing bowls by note or carefully matched singing bowl sets.
Protective Packing and Export from Balaju
Approved products are transferred to a separate HSB export location in Balaju. There, the team prepares protective packing according to the product, order size and destination. Bowls must be immobilised and separated so that they cannot strike each other during transport. Large bowls and mixed wholesale orders require additional reinforcement and careful weight distribution.
Once packed and documented, shipments are transferred from Balaju to Kathmandu airport for international transport. Customers can review our shipping, delivery and returns information for current destinations, costs and conditions.

Wholesale, Custom and Private-Label Production
Our production network supports individual customers, professional practitioners, retailers and international brands.
Standard wholesale products can be ordered through our Wholesale Singing Bowls from Nepal programme. Depending on technical feasibility and order volume, HSB can also coordinate specific sizes, selected notes, custom finishes, logo engraving, prototypes and repeatable private-label collections.
Because every bowl is hand-hammered, natural variations remain part of the product. Our role is to define realistic specifications, select the appropriate production and finishing methods, inspect the finished pieces and communicate clearly about what can be reproduced.
