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 Foundry Sand Casting Foundry Sand Casting Foundry Sand Casting Processes in the Foundry * 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. Composition of Foundry Sand * Remnants of metal from the casting process as well as mold and core material with the binder in a partially degraded form; 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.

What is die casting? Essentially, die casting uses steel molds called dies which molten metal is forced into using extremely high pressure. From steel sinks to tiny toy cars, die casting is a versatile technique that allows for various levels of complexity in production, while still maintaining absolute precision to create a flawless end product. The Four Steps of Investment casting There are four key steps in the process of die casting, and each must be fully completed before moving onto the next phase. However, before these steps can begin, the die worker must ensure that the die casting machine is at the required temperature. If the die is still cold when the molten metal is injected, it will solidify too quickly without conforming to the correct shape. According to the size of the intended cast, heating can take anywhere from several hours to several minutes. After the die has reached the right temperature for the job, casting can begin. 1) Spray the mold with lubricant and close it. This helps to regulate the temperature inside of the die, while also allowing for an easier removal of the cast object later on. The lubricant functions much in the same way as household cooking spray is used on a baking pan. 2) Inject the molten metal into the die. The metal is inserted at an extremely high pressure, which allows the metal to conform to the precise shape of the sand casting,Precision machining without the dangers of lumps or air pockets inside the product. 3) Cool the mold, and wait for the metal to solidify. In some cases, the mold may be immersed or sprayed with cold water to help the casting become solid faster than simply waiting for it. A high pressure is maintained inside the mold, which ensures the metal doesn¡¯t change properties while inside the die. 4) Open the die and remove the solid cast! There are several secondary steps which may need to be taken once the casting is removed, such as removing excess metal and smoothing rough surfaces. However, die casting can create pieces of metal as thin as 1mm wide in these four simple steps, which makes it a more economic process than using stamping presses or machine tools that require the operation of multiple pieces of large machinery for metalwork. The Life of a Die A die casting die is built to do several things, each of equal importance, and quite often the die itself cannot produce a completed final product. While a die holds the liquid metal inside itself to create a cast, there also must be a place for the metal to enter the die and reach the inside. This means that when the metal cools, there will be small pieces of unwanted metal attached to the final cast called flash, which will need to be removed by hand or secondary machine. Hydraulic presses can be used to remove the flash or scrap, while an older technique is to just saw off the flash by hand. A casting may need to be sanded or ground down to remove mold lines, and if any extra holes for screws or undercutting is necessary, this must be done outside of the die as well. Die casting machines can apply a clamping force that ranges from 100 to 4,000 psi, and are typically divided into categories according to the type of metals they can cast. Hot chamber dies can cast metals with lower melting points, such as zinc, while cold chamber dies cast metals with higher melting points like aluminum. Die casting dies typically have a lengthy lifespan, however over the course of several hundred thousand heatings and coolings, the dies' properties may begin to shift and weaken. Dies which make castings from aluminum and its alloys tend to have a shorter lifespan, simply due to the temperature required to make aluminum casts, while cold chamber dies tend to last almost indefinitely. Die sets for casting brass objects are extremely short-lived, and need to be replaced frequently, regardless of the strength of the cast. | ||

| Die casting is a metal forming process in which molten metal is put under pressure and injected into a die. The molten metal enters the die cavity through sprue holes in the fixed die half. The melt is directed to the cavity by runners (passageways) and gates (inlets) in the ejector half. Locking pins on the die secure the two halves together. The metal, kept just above its melting temperature, quickly solidifies into the shape of the Die casting. Ejector pins remove the die cast part. Die castings are made from alloy tool steels. They have at least two sections to permit the removal of castings, the fixed die, or cover, half and the ejector die half. Some dies also have parts, such as removable slides and cores, to produce holes, threads and other desired shapes in the casting. Openings in the die allow the addition of coolant and lubricant. Dies are either air- or water-cooled. The cooling of the die provides for quick cycling and is one of the factors in the high rate of production. It also gives a fine grain structure and superior strength and finish to the metal castings. The molds used by die casting manufacturers will perform up to 5 million shots in its lifetime. The services provided by die casting http://www.soocasting.com manufacturers have many advantages over other processes. Die casting is efficient and economical, offering a wide range of durable shapes and components. Little or no machining is required after die castings are made because the process provides very close tolerances for even complex part shapes. Metal castings can be easily plated or finished. Die castings are dimensionally stable and heat resistant. These lightweight parts, even while having thin walls, retain the strength of an alloy because they do not consist of separate parts welded together. Die casting manufacturers utilize a number of materials, including Zinc, Aluminum, Magnesium, Copper, lead and tin. Zinc is the easiest alloy to cast, has a low melting point and is economical and easily palatable. Sand Casting Zinc also has high impact strength, offers high ductability and promotes long die life. Aluminum alloys possess high dimensional stability for complex shapes and thin walls. Aluminum die casts are of a lightweight alloy that has good corrosion resistance, mechanical properties, high thermal and electrical conductivity and strength at high temperatures. Along with being the easiest alloy to machine, magnesium is also the lightest typically die cast. Magnesium die casting also has excellent strength-to-weight ratio. Copper is one of the hardest alloys and offers the highest mechanical properties of any other alloy that is cast. A dimensionally stable alloy, copper has high corrosion and wear resistance and strength approaching that of steel parts. Lead and tin are used for special forms of corrosion resistance. Although they have high density, parts with extremely close dimensions are able to be formed from lead castings and tin castings. | ||

A Sand Casting or a sand molded casting is a cast part produced by forming a mold from a sand mixture and pouring molten liquid metal into the cavity in the mold. The mold is then cooled until the metal has solidified. In the last stage the casting is separated from the mold. There are six steps in this process: 1 Place a pattern in sand to create a mold. 2 Incorporate a gating system. 3 Remove the pattern. 4 Fill the mold cavity with molten metal. 5 Allow the metal to cool. 6 Break away the sand mold and remove the casting. During casting, some of the components of the sand mixture are lost in the thermal casting process. Green sand can be reused after adjusting its composition to replenish the lost moisture and additives. The pattern itself can be reused indefinitely to produce new sand molds. The sand molding process has been used for many centuries to produce castings manually. Since 1950, partially-automated casting processes have been developed for production lines.

Unlike most of our competition, we offer three types of castings – aluminum sand casting, gravity die casting and aluminum die casting. We can also provide tooling, CNC machining, polishing, plating, heat treatment, pressure test, vacuum Impregnation, assembly and testing for your orders. Foundry processes can be divided into two types:- ferrous foundries and non-ferrous foundries. Foundry processes involve making the mould and the core, melting and pouring the metal into the mould, and finally removing the mould and core and finishing the product. Although different processes differ in the number of steps required to make the final product. Metal casting process starts with creation of mold. Metal that can be molted will be poured into this mould and cooled. The form of metal being used and shape of final product required would decide the material, which will be used to make the cast. A commonly used molding material is sand. Investment materials, metals, etc. can also be used. Different types of metals are used for melting different metals. Various Furnaces types are cupolas, electric arc, induction, hearth or reverberatory and crucible. Due to the different nature of metals, varying inputs are required and different toxic wastes are released from each type. After the metal has been melted, it is poured into the cast already made previously and made to cool and set. Silica sand, moisture, oils and green sand are mixed together to form a mould cavity. Metal is then poured in this cavity. When the metal is cooled, it is easily separated from the mould. This type of sand should b capable of handling high temperatures and pressure, allow gases to escape, have a constantly small grain size and be non-reactive with metals.

A motorcycle (also called a motorbicycle, motorbike, bike, or cycle) is a single-track, two- wheeled motor vehicle. Motorcycle varies considerably depending on the task for which they are designed, such as long distance travel, navigating congested urban traffic, cruising, sport and racing, or off-road conditions. Motorcycle is the most affordable form of motorised transport in many parts of the world, and for most of the world's population, they are also the most common type of motor vehicle. There are around 200 million motorcycles (including mopeds, motor scooters and other powered two- and three-wheelers) in use worldwide, or about 33 motorcycles per 1000 people. This compares to around 590 million cars, or about 91 per 1000 people. Most of the motorcycles, 58%, are in the developing countries of Asia, while 33% of the cars (195 million) are concentrated in the US and Japan. In the two countries of India and China, there are a total of only 6 million cars, but 71 million motorcycles. These numbers, worldwide, are dwarfed by the number of bicycles in use, estimated to be near twice the number of cars, or close to five times the number of motorcycle. There are many kinds of motorcycles.
