Rama : Brief Introduction
Rama Ram, also known as Ramachandra, is a major deity in Hinduism. He is the seventh avatar of Vishnu, one of his most popular incarnations along with Krishna, Parasuraman, and Gautama Buddha. Jain Texts also mentioned Rama as the eighth balabhadra among the 63 salakapurusas. In Sikhism, Rama is mentioned as one of twenty four divine incarnations of Vishnu in the Chaubis Avtar in Dasam Granth. In Rama-centric traditions of Hinduism, he is considered the Supreme Being.
Rama was born to Kaushalya and Dasharatha in Ayodhya, the ruler of the Kingdom of Kosala. His siblings included Lakshmana, Bharata, and Shatrughna. He married Sita. Though born in a royal family, their life is described in the Hindu texts as one challenged by unexpected changes such as an exile into impoverished and difficult circumstances, ethical questions and moral dilemmas. Of all their travails, the most notable is the kidnapping of Sita by demon-king Ravana, followed by the determined and epic efforts of Rama and Lakshmana to gain her freedom and destroy the evil Ravana against great odds. The entire life story of Rama, Sita and their companions allegorically discusses duties, rights and social responsibilities of an individual. It illustrates dharma and dharmic living through model characters.
Rama is especially important to Vaishnavism. He is the central figure of the ancient Hindu epic Ramayana, a text historically popular in the South Asian and Southeast Asian cultures. His ancient legends have attracted bhasya and extensive secondary literature and inspired performance arts. Two such texts, for example, are the Adhyatma Ramayana – a spiritual and theological treatise considered foundational by Ramanandi monasteries, and the Ramcharitmanas – a popular treatise that inspires thousands of Ramlila festival performances during autumn every year in India.
Rama legends are also found in the texts of Jainism and Buddhism, though he is sometimes called Pauma or Padma in these texts, and their details vary significantly from the Hindu versions.

Process: Sand Casting
This Tibetan Door Lock has been created using the sand casting system, also known as sand molding casting. This widely employed manufacturing process utilizes a sand mold to produce metal products and components in various sizes and shapes. Sand casting holds significant popularity in the industry, accounting for approximately 60% of all metal castings. The sand casting process involves six primary steps. First, a pattern or replica of the desired sculpture, in this case, Tibetan Door Lock, is created using a material like wood or metal. The pattern is then placed in a flask, which is a box-like structure divided into two halves. The next step involves packing the flask tightly with specially formulated molding sand, creating a mold cavity that matches the shape of the pattern. The pattern is subsequently removed, leaving behind a negative impression of the sculpture within the sand mold.
The third step is known as gating and risering, where additional channels and reservoirs are added to the mold to facilitate the flow of molten metal and compensate for any shrinkage during solidification. Once the gating system is prepared, the mold is carefully closed and secured. The fourth step involves pouring the molten metal, such as bronze or iron, into the mold through the gating system. After the metal has cooled and solidified, the mold is broken open, revealing the solid metal sculpture. The final steps involve removing any excess material, surface finishing, and polishing to achieve the desired appearance.
Sand casting offers several advantages, including its versatility in producing complex shapes, cost-effectiveness for both small and large-scale productions, and the ability to use a wide range of metals. However, it does require skilled craftsmanship and careful attention to ensure the quality and accuracy of the final sculpture. By utilizing the sand casting system, the Tibetan Door Lock embodies the craftsmanship and artistry of the process, resulting in a captivating and unique metal artwork.
The process cycle for sand casting consists of six main stages, which are explained below
Mold-making -The first step in the sand casting process is to create the mold for the casting. In an expendable mold process, this step must be performed for each casting. A sand mold is formed by packing sand into each half of the mold. The sand is packed around the pattern, which is a replica of the external shape of the casting. When the pattern is removed, the cavity that will form the casting remains. Any internal features of the casting that cannot be formed by the pattern are formed by separate cores which are made of sand prior to the formation of the mold. Further details on mold-making will be described in the next section. The mold-making time includes positioning the pattern, packing the sand, and removing the pattern. The mold-making time is affected by the size of the part, the number of cores, and the type of sand mold. If the mold type requires heating or baking time, the mold-making time is substantially increased. Also, lubrication is often applied to the surfaces of the mold cavity in order to facilitate removal of the casting. The use of a lubricant also improves the flow the metal and can improve the surface finish of the casting. The lubricant that is used is chosen based upon the sand and molten metal temperature.
Clamping - Once the mold has been made, it must be prepared for the molten metal to be poured. The surface of the mold cavity is first lubricated to facilitate the removal of the casting. Then, the cores are positioned and the mold halves are closed and securely clamped together. It is essential that the mold halves remain securely closed to prevent the loss of any material.
Pouring - The molten metal is maintained at a set temperature in a furnace. After the mold has been clamped, the molten metal can be ladled from its holding container in the furnace and poured into the mold. The pouring can be performed manually or by an automated machine. Enough molten metal must be poured to fill the entire cavity and all channels in the mold. The filling time is very short in order to prevent early solidification of any one part of the metal.
Cooling - The molten metal that is poured into the mold will begin to cool and solidify once it enters the cavity. When the entire cavity is filled and the molten metal solidifies, the final shape of the casting is formed. The mold can not be opened until the cooling time has elapsed. The desired cooling time can be estimated based upon the wall thickness of the casting and the temperature of the metal. Most of the possible defects that can occur are a result of the solidification process. If some of the molten metal cools too quickly, the part may exhibit shrinkage, cracks, or incomplete sections. Preventative measures can be taken in designing both the part and the mold and will be explored in later sections.
Removal - After the predetermined solidification time has passed, the sand mold can simply be broken, and the casting removed. This step, sometimes called shakeout, is typically performed by a vibrating machine that shakes the sand and casting out of the flask. Once removed, the casting will likely have some sand and oxide layers adhered to the surface. Shot blasting is sometimes used to remove any remaining sand, especially from internal surfaces, and reduce the surface roughness.
Trimming - During cooling, the material from the channels in the mold solidifies attached to the part. This excess material must be trimmed from the casting either manually via cutting or sawing, or using a trimming press. The time required to trim the excess material can be estimated from the size of the casting's envelope. A larger casting will require a longer trimming time. The scrap material that results from this trimming is either discarded or reused in the sand casting process. However, the scrap material may need to be reconditioned to the proper chemical composition before it can be combined with non-recycled metal and reused.
