Different Types of Castings and Their Maintenance

Metallic and non-metallic goods are a dominant part of our everyday life. From transportation to communication devices, there is barely any sector of an individual’s life that does not involve industrially manufactured goods. By the same observation, one can satisfactorily conclude that casting indeed remains a crucial process for our civilization because it is the only technique that allows the production of desired objects from natural mineral resources.

Basically, casting is a manufacturing process that involves pouring liquid metals in hollow molds of set sizes and shapes for the creation of solid objects. Depending upon the demand, casting exporters offer many kinds of casts including the ones made up of aluminum, steel, iron, metal alloys, and zinc. However, not all types of cast goods can be manufactured using the traditional casting technique. Hence, a number of casting process types have been developed by engineers, some of which can be enumerated as follows:

#1. Sand Casting
The cheapest and commonly used casting process is sand casting, where cast molds are created of a hardened mixture of sand and water. Patterns for products are carved on wood, so thorough machining is required to make the cast goods reach their desired quality. The biggest advantage of the sand casting process is that it can produce complex metal cast goods at lowest prices. However, the secondary costs of production (like surface shining and chiseling) reduce its application to primary industries.

#2. Shell Casting
Thin metallic or non-metallic cast goods like turbine fans are manufactured using shell casting technique. For conducting this process, patterns are made out of high endurance metals, while casting molds are typically composed of sand. Taking away from the primitive sand casting technique, this type of processing helps to produce goods with better surface quality.

#3. Investment Casting
Probably the most expensive but effective technique of processing, investment casting has made a mark of its own in the industrial landscape. It is considered advantageous for new age technology because it can produce goods with the highest of accuracy and surface finish. In addition, its enhanced speed of manufacturing also aids in keeping up with the demand of the market.

#4. Plaster Mold Casting
As the name suggests, this technique uses plaster molds for creating metallic goods. Patterns are drawn onto the plaster mold and the heated metal is allowed to cool down inside of the same. Its capabilities are lemmatized and hence, only zinc and aluminum goods can be cast using this process.

Casting exporters often note that the foundries become highly dangerous workplaces as a result of the complex machinery that is used in its premises. Casting instruments are specifically some of the most attention-seeking assets, for any negligence in their maintenance can result in massive losses. Here is a list comprising some practices that can help keep casting instruments in their best shape for an extended duration of time:

#1. Use High-Quality Supplementary Materials
Machinery demands like lubricants are fairly common to every kind of technological product. To ensure the best performance, automatic casting instruments must be lubricated and supplemented with the best grade products.

#2. Create a Healthy Work Environment
Effluents from the industry can degrade the machines used to make casts or conduct the process. So, wastewater, solid waste, and gaseous emissions must be channelized towards a safe exit away from the industrial area.

#3. Stock Management
Training workers to install casting instruments’ parts cannot be beneficial until industries maintain a wealthy stock of their spare parts that can be accessed at any emergency situation.

The casting industry has been developing fastidiously, the proof of which is the increasing number of casting exporters. Today, no industry can do away with the need for using cast goods.
