Foundries

Introduction: A foundry is where the elaborate metal casting process takes place. A metal foundry may specialize in making one particular item or a variety of products using different alloys. Based on the production requirement, there are small foundries that employ few people and large industrial foundries that employ thousands of workers. History: Foundry operations of the present day is an outcome of…

Definition

Casting is a method where a solid material is dissolved, heated to suitable temperature (generally treated to change its chemical structure), and is then added into a mold or cavity, which keeps it in a proper form during solidification. As a result, in just one step, complex or simple designs can be created from any material that can be dissolved.…

Components for Pumps & Valves

A variety of casting methods are used for making the components for pumps and valves. They can be done using either ferrous or non-ferrous casting methods. Using Ferrous Casting Pump and Valve components can be cast using the following processes malleable iron casting, gray iron casting and ductile iron casting. Advantages of each of the casting methods are enumerated below…

Automobile Casting Equipment

The automobile industry offers a huge market for the cast products using ferrous, non-ferrous metals and its alloys. Various casting methods are used to produce automobile accessories that are light in weight, easy to maneuver, and cheap. Zinc Die Casting and Aluminum Die Casting are two most popularly used processes to produce automobile casting equipment. Zinc Die Casting :By using…

The Metal Casting Operation

Pouring, Fluidity, Risers, Shrinkage And Other Defect In the previous section the fundamentals of the metal casting process, as the basic starting point for metal fabrication and part manufacture, were covered. Setup and design of a system to perform a casting operation was explained. Main topics were molds, patterns, cores, and the elements of a gating system. In this section…

Metal Casting Processes

  Metal Casting Processes Foundry Process Process Pros / Cons Green Sand Molding The green sand process utilizes a mold made of compressed or compacted moist sand packed around a wood or metal pattern. A metal frame or flask is placed over the pattern to produce a cavity representing one half of the casting. The sand is compacted by either jolting…

Founding

Founding, the process of pouring molten metal into a cavity that has been molded according to a pattern of the desired shape. When the metal solidifies, the result is a casting—a metal object conforming to that shape. A great variety of metal objects are so molded at some point during their manufacture. The most common type of mold is made of sand and clay; ceramics, sand with cement, metals,…

Casting Designing Framework

To approach an ideal framework for designing a metal casting requires a detailed study of the contradictory requirements and identifying the best solution. The artifact’s designing, quality-benchmarking and cost-effective considerations play an important role to work out an ideal structure for metal casting. Advantages of defining framework: To design functionally stable cast products with production techniques using minimal development time.…

Casting Process

Consider the casting process at 645 B.C, the first traces of the Sand Molding was found. Now consider the state-of-the-art Electromagnetic casting process. Truly, the Casting process has traversed a long path and impacted human civilization for nearly five millennia. With technological advances, metal casting is playing a greater role in our everyday lives and is more essential than it…

Casting Alloys

The wide range of casting alloys helps in selecting the most suitable and cost effective material that meets the requirements of a particular application. Each of these casting alloy has its own physical and mechanical properties. They also have their own casting characteristics, like: Weldability Machinability Corrosion resistance Heat treatment properties Did You Know Bronzes are unquestionably the most versatile…
