OUR CASTING PROCESS
At Viva, we are able to create castings that precisely match the geometric requirements and features of your project. Our team’s ability to deliver tiny one-off orders to demanding continuing production schedules and everything in between is made possible by our on-site infrastructure. We manufacture accurate parts and precision components with tolerances that lead the industry and acceptable mechanical qualities. We can meet your budget and production schedules while producing parts and components quickly and precisely.
Die Casting
In the metal casting process known as ``die casting,`` molten or liquid metal is forced into a metal mould. Usually, the mould is made from two steel dies that have been hardened and machined into the required shape. One of the most popular processes for creating parts with excellent dimensional stability for a range of applications is die casting. In a novel procedure known as die casting, molten metal is forced into a mould cavity at extreme pressure.
Aluminum Die Casting
Aluminum die casting services provide precise, high-quality manufacturing solutions. With a variety of aluminum alloys and cutting-edge methods, we can fabricate intricate forms with remarkable corrosion resistance, strength-to-weight ratios, and great dimensional stability.
Gravity Die Casting
Created by coating the cavity and melting the metal that is poured in it this uses gravity to introduce molten metal into a mold's cavity and till the metal solidifies.The process uses automatic or manual machines. This method is still effective for smaller parts, finding use in a variety of applications including: kitchenware, lighting, and automobiles.
Pressure Die Casting
Modern metal processing methods like high-pressure die casting involve quickly and rapidly filling a mold with molten metal to create castings. It boasts strong mechanical properties, minimal machining, high production efficiency, and excellent surface finish.
Shell Molding / Resin Sand Casting
A thin mold is made around a heated metal pattern as part of the precision casting process known as shell molding. Dry silica sand combined with a thermosetting resin forms a shell that is about 6 mm thick around the pattern. This shell is then dried, stripped, and joined to form a cavity for pouring molten metal. For the mass production of thin-walled castings, shell molding is the best option because it offers dimensional accuracy and a superior surface finish.
Investment Casting
investment casting is a painstaking process where ceramic molds are created around wax patterns to encapsulate molten metal. A gate system can have multiple wax patterns melted onto it. The pattern(s) is/are then submerged in slurry and sand to create a multilayer casing. Melted metals, such as aluminum or stainless steel, are poured in to create incredibly detailed reproductions when the wax is removed.
Centrifugal Casting / Roto casting
The centrifugal casting is used to create thin-walled cylinders from materials like metal, glass, and concrete. It produces a fine-grained casting with rotational symmetry by rapidly rotating a permanent mold while pouring molten material. Instead of producing custom-shaped parts, the centrifugal casting method is often employed to produce standardized stock materials for further machining. Molds are made of steel, cast iron, or either graphite.
Sand Casting
A sort of metal casting manufacturing process called ``sand casting`` uses sand to form a mould. The finished product is poured into the sand mould using molten metal. Metal goods in a variety of sizes and forms are produced using this manufacturing technique.
