About the Product

Process: Sand Casting
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.Green Tara: Brief IntroductionSamaya Tara popularly known as Green Tara. She is represented in a royal ease posture with her left leg bent her left leg overstepping the main lotus and resting on a blue lotus ready to get up and offer assistance to those in need. She is portrayed with maroon Buddhist robes and jewelry. The earrings represent patience understanding and renunciation. The diadem with five jewels represents the transmutation of the five delusions into the Five Buddha Wisdoms. She is shown with a benevolent countenance seated upon a white moon disk which is associated with special restorative nectar associated with the naval chakra center. In Buddhists the moon symbolizes the wisdom aspect which when coupled with compassion leads to Sakyamuni Buddha's enlightenment. Her right hand is gracefully lowered in varada mudra the boon-granting gesture.IconographyGreen Tara's special lotus is the blue lotus or 'night lotus' which she bears in both hands. The word utpala means to 'burst open'. Her left hand holds a stem with an open blooming flower and an unopened bud. The bent lower part of the stem represents the root. The open blossom represents the present and also the present Buddha; the bud represents the future and also Buddhas yet to be born. The future here also refers to a safe journeys end and a future well being. Her right hand wisdom hand is in the gesture of giving refuge. The third finger touches the thumb to create a circle representing the union of wisdom and compassion and the three extended fingers symbolise the Three Jewels of Buddhism a. The Buddha State b. The Body of teachings c. The Principles of the Universe The same hand holds the stem of a blue lotus representing her willingness to assist. The closed blossom in her right hand represents the past and also the Buddhas of the past. Green Tara is shown in a place of paradise called Khadiravani where she Tara dwells. Khadiravani is described as a great mountain kingdom with many trees flowers and animals (not shown). 3 rainbow tails emanate from her outer aureole. The crescent moon and sun symbolise the union of male and female ubiquitous in Tantric art.
The seventy two golden lines represent psychic energy channels emanate from her body and her central psychic channel running up her spinal column. Each one signifies a thousand as there are traditionally seventy two thousand channels. The gold lines alternate between wiggly and straight to represent the two main psychic channels running up the central channel that entwine to create the interlocking 'snaking' caduceus and to which the energy channels are connected. The trees in the foreground are the Ashoka Tree. The word ashoka means 'without sorrow' and is the tree linked to the Vedic God of love and sexual union Kamadeva. Apparently the tree blossoms when a virtuous lady touches it.CommentaryThe word Tara means the one who saves. The word Tara is derived from the root trimeaning to cross and in context is taken to mean the one who helps people to cross the Ocean of Existence and Suffering. Green Tara is also called 'dark' Tara or more directly Shyama Tara. Green Tara is associated with the Amoghasiddhi who is also green and the north facing Meditation who is head of the action family. Her willingness to help others is shown by her body posture with one foot ready so that she can rise to offer assistance. Like WhiteTara she was born of the tears of compassion of the Bodhisattva Avalokiteshvara resulting from the extreme state of sadness he experienced when observing the continuing ceaseless suffering which he sought to end.
