As a Customized manufacturer there are different steps in our production process. These processes and steps are flexible and can be reduced or increased as per the requirement of product and customer

The very first step of the process is to either create a design or to evaluate the existing design. It’s done for several reasons including –
• Identifying and aligning with the objective of clients
• Planning the most accurate process of manufacturing,
• Analyzing the drawing for errors and loopholes,
• Deciding the material of choice and preparing the same.
RVI designs and evaluate the existing designs to offer desired results to clients.

Die and Tool making

Die development is an integral part of product manufacturing for both Casting and Forging brass products. It’s a specialized machine tool used to cut and/or form material to a desired shape or profile.
Generally, for our industry the dies are made of special metal and harden able steel. We generally customize die to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology.
Dies can be used for processes including sheet cutting, stamping, forging, casting and such similar operations.


The casting process is basically accomplished by pouring liquid brass or other metal into a die which is in the shape of the desired part and allowing it to cool.

Preferable casting methods for Brass –
• Sand Casting
• Pressure Die Casting
• Lost-Wax Casting
Casting process can be cost-effective when producing at larger scale and can help in making complex shapes with ease.


A large part of brass metal components is made using forging process.

Forging is when a manufacturing process involves the shaping of a metal through hammering, pressing, or rolling. These compressive forces are delivered with a hammer or die. Forging is often categorized according to the temperature at which it is performed-cold, warm, or hot forging.

The process begins with the cutting of the brass bars to the length of the product being made. It is then heated to achieve permeability and then pressed in between dies at high pressure. Cooling then follows after which the flash is trimmed and machining of the forging blank done to finish the product.
Different type of forgings for Brass-
• Drop forging
• Open-die forging
• Closed-die forging
• Press forging
• Precision forging

Some typical forged or formed brass components
• Plumbing fittings for many types of fluids especially water faucets and taps
• Components used in outdoor environments such as metal fitting on boats and vehicles
• Knobs, handles and many “hand-touch” items that require antimicrobial properties
• Bushings and bearings where the “self-lubricating” properties of a copper-based alloy are an advantage


RVI offers machining for brass products including forging parts, casting parts and extrusion rod cuttings.

In Machining we include –
• Turning
• Milling
• Drilling/Boring/Reaming
• Cutting and Grinding
• Planing and Shaping
• Threading
• Grooving
• Broaching
• Sawing

Surface Treatment

Surface treatment is a process of artificially forming a surface layer on the surface of the base material that is different from the mechanical, physical, and chemical properties of the base body. The purpose of surface treatment is to meet the requirements of corrosion resistance, wear resistance, decoration or other special functions of the product.

We offer following surface treatment for brass metal products-
1. Mechanical Surface Treatment: sand blasting, shot blasting, polishing, rolling, brushing, etc.

2. Chemical Surface Treatment: blue and black, phosphating, pickling, electro-less plating of various metals and alloys, chemical oxidation, etc.

3. Electrochemical Surface Treatment: anodizing, electrochemical polishing, electroplating, etc.

4. Pickling Passivation: refers to the process of immersing metal parts in the pickling Passivation solution until the surface of the work piece becomes uniform and silver-white.

5. Electrolytic Polishing Treatment: Electrolytic polishing, also known as electrochemical polishing, which refers to a process in which a work piece is placed in a solution that is energized to improve the flatness of the surface of the metal work piece and make it shiny.

All these Surface treatments are done on the advice and as per the requirement of clients.

Packing and Shipment

Packing of the products is done to ensure the protection of items from certain mishaps that can occur during transition.

1. Packing Goods in Strong, Lightweight Containers
2. For overseas transits loading cargos in Shipping Container or Securely on Pallets
3. Individual packing and wrapping of items.
4. Labeling of material to avoid misplacement
5. Adhering to customer’s suggestions and requirement for packaging of material.

As for the shipping and transit we offer different options depending on the urgency of delivery or specific instructions given by customers.


If you have any other specific requirement that hasn’t been mentioned here or you want some detailed information on any process, then we welcome you to contact one of our representatives.
