Ruican Sand Casting is specialized in manufacturing Sand Casting, Investment Casting, Die Casting, Green Sand Casting,Sand Casting Part,Sand Mold Casting.

Foundry sand is used for making castings, and is primarily generated by the automotive industry and its part suppliers (these deliver  approximately 95 of foundry sand). It consists of clean silica sand  which is of high quality or lake sand which are bonded to make molds for   ferrous (iron and steel) and non-ferrous (copper, aluminum, brass)  metal castings. The following types of sands are used for making molds  in the foundry industry: Green Sand, Resin Coated Sand, Molasses, Cold  Box Sand, Hot Box Sand, and CO2 Sand.

Sand Casting Processes in the Foundry
The two commonly used casting processes in the foundry system are as follows:

* The Sand Cast Systems --- The sand used for making sand cast moulds   for ferrous castings is largely green sand which comprises of silica  sand of high quality, around 10 per cent bentonite clay (which acts as  the binder), up to 5 per cent water and about 5 per cent sea coal (which   is an additive for improving the casting finish). This green sand forms  more than 90 per cent of the molding materials utilized in the process.  Various types of metals can be cast and it is the type of the metal  that determines the gradation of the sand and the additives that are  used in these systems.
* Chemically Bonded Sand Cast Systems ---  These systems are used for 'cores' for producing cavities, which cannot  be easily produced through usual molding procedures and also for molds  for nonferrous castings. Here one or more organic binders are utilized  along with catalysts and various setting techniques. Foundry sand  constitutes around 97 per cent of this mixture.

Composition of Foundry Sand
While before being used, foundry sand is uniformly graded, the spent sand often contains

* Remnants of metal from the casting process as well as mold and core material with the binder in a partially degraded form;
* Leachable contaminants such as heavy metals and phenols which are  absorbed by the sand in the course of the molding procedures (these  phenols are produced by the thermal decomposition, at high temperatures,   of the organic binders during the process of pouring the metal);
* And, more specifically, high concentrations of elements such as  cadmium, lead, nickel, zinc and copper in brass and bronze foundries.

The  green sand moulding process requires sand, clay and water to be mixed  together to form a mould material that can be compacted around a pattern  to produce a mould. Water develops the bonding characteristics of the  clay, which binds the sand together, when used in its moist condition it  is referred to as green.

When rammed and compacted around a  pattern a mould of sufficient strength is produced to allow metal to be  poured into it to produce a casting.

The green sand process can  be used to produce castings in both aluminium and copper based metals.  The process allows 90% to 95% reclamation of material and so provides a  low cost form of production.

In essence we will always find the  most suitable and cost effective method to casting whatever your  requirement whether it be for individual light castings or multiple  heavy castings.

Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a parting line and the solidified casting can be removed. The steps in this process are described in greater detail in the next section. In sand casting, the primary piece of equipment is the mold, which contains several components. The mold is divided into two halves - the cope (upper half) and the drag (bottom half), which meet along a parting line. Both mold halves are contained inside a box, called a flask, which itself is divided along this parting line. The mold cavity is formed by packing sand around the pattern in each half of the flask. The sand can be packed by hand, but machines that use pressure or impact ensure even packing of the sand and require far less time, thus increasing the production rate. After the sand has been packed and the pattern is removed, a cavity will remain that forms the external shape of the casting. Some internal surfaces of the casting may be formed by cores.

Sand casting is used to produce a wide variety of metal components with complex geometries. These parts can vary greatly in size and weight, ranging from a couple ounces to several tons. Some smaller sand cast parts include components as gears, pulleys, crankshafts, connecting rods, and propellers. Larger applications include housings for large equipment and heavy machine bases. Sand casting is also common in producing automobile components, such as engine blocks, engine manifolds, cylinder heads, and transmission cases.

Sand casting is able to make use of almost any alloy. An advantage of sand casting is the ability to cast materials with high melting temperatures, including steel, nickel, and titanium. The four most common materials that are used in sand casting are shown below, along with their melting temperatures.

Materials             Melting temperature    
Aluminum alloys     1220 °F (660 °C)   
Brass alloys           1980 °F (1082 °C)   
Cast iron               1990-2300 °F (1088-1260 °C)   
Cast steel              2500 °F (1371 °C)   

The material cost for sand casting includes the cost of the metal, melting the metal, the mold sand, and the core sand. The cost of the metal is determined by the weight of the part, calculated from part volume and material density, as well the unit price of the material. The melting cost will also be greater for a larger part weight and is influenced by the material, as some materials are more costly to melt. However, the melting cost in typically insignificant compared to the metal cost. The amount of mold sand that is used, and hence the cost, is also proportional to the weight of the part. Lastly, the cost of the core sand is determined by the quantity and size of the cores used to cast the part.

Alloys of aluminium are used in die  casting more extensively than alloys of any other base  metals.
Die casting is especially suited to production of large quantities  of relatively small parts. The more important reasons for using light  metal casting are low weight, mechanical strength, stiffness and  electrical properties. Other applications are e.g. components for the  power transmission line in the vehicle industry and electronics  industry.

Typical applications of die cast aluminium alloys include:

* · Alloy 380.0 - Lawnmower housings, gear
* · Alloy A380.0 - Streetlamps housings, typewriter frames, dental  equipment
* · Alloy 360.0 - Frying skillets, cover plates, instrument cases,  parts requiring corrosion resistance.
* · Alloy 413.0 - Outboard motor parts such as pistons, connecting  rods, and housings
* Alloy 518.1 - Escalator parts, conveyor components, aircraft and  marine hardware and lit tings.

With die casting, it is possible to maintain  close tolerances and produce good surface finishes. Die castings are made by injection of molten metal into metal molds under  substantial pressure. Rapid injection and rapid solidification under  high pressure combine to produce a dense, fine-grain surface structure,  which results in excellent wear and fatigue properties. Our factory have  Large spectrum of die casting machines (280T - 1600T),it can produce  Variety of alloys available to meet in house production requirements and  to provide quality custom-made die-casting parts for other industries
