About the Product

Finishing: Stone Setting

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.

 

Naga Kanya: Brief Introduction

Naga Kanya means in Sanskrit the virgin the maiden of the Nagas. This picture refers to a beautiful Buddhist tale narrated in the XIIth chapter of the Lotus Sutra where a Naga princess daughter of the Ocean (Sagara) comes to bodhicitta at the tender age of eight. Before an incredulous assembly of bodhisattvas (because she was so young and a woman) the Nagini offers then to the Buddha a jewel said to be worth thousands of worlds. When the bodhisattvas tell her that the Buddha accepted her jewel immediately she told them to watch her become a buddha even more rapidly. The common interpretation of this myth is that her jewel was in truth her very own life worth indeed thousands of worlds and the gift of which was the ultimate price whether it be spontaneous or the work of an entire life.IconographyNaga Kanya is usually seen as a very beautiful young girl in sited position holding precious jewels with her both hand in offering posture She has 5 headed snake on top of her head as a crown and wings representing she has the ability to fly.
