    Alloy Steel Casting

    Alloy Steel Casting is carbon steel, based
    on the microstructure and the corresponding carbon steel is
    generally similar. Significantly improve the mechanical properties
    of the steel alloying elements in steel. In recent years, with the
    development of society and scientific and technological progress,
    the growing demand for low-alloy steel castings.


    In order to overcome the low alloy steel in a coarse grains large
    thermal cracking and the tendency to temper brittleness greater
    shortcomings, the casting process should strictly control the
    production of each process and technology operations and take
    effective measures to prevent or reduce the generation of casting
    defects, especially control of the smelting process and casting hot cut
    process control is a critical part of the low alloy steel castings
    production.

    Nonwoven product

    Nonwoven fabric is made from long fibers, which
    is a fabric-like material bonded together by chemical, mechanical,
    heat or solvent treatment. Nonwoven fabric is used
    in the textile manufacturing industry to denote fabrics, such as
    felt, which are neither woven nor knitted. Nonwoven materials
    typically lack strength unless densified or reinforced by a
    backing. In recent years, nonwoven products have
    got a fast development and now become an alternative of
    polyurethanefoam.

    The market of LED lamp is growing fast, and we believe the LED technology will be the most important illumination in near future. And in the coming days, we will pay more attention on the following points:


    First, the current LED lamps are mostly designed for traditional lamp replacement, but as LED chip is small size, energy saving and long lifespan, the LED lamp should be personalized, which can give full play to these advantages.


    Second, the lifespan of led chip can be as long as 100 000 hours, while the led driver’s can only be 10 000 to 20 000 hours, which means when the led driver stop working, the led chip still can be used. LED driver with better reliability is needed. It’s the basic of LED applications.


    Third, to make the life be more comfortable and colorful, functional controller like IR sensor, color temperature controller should be used on more and more LED lamps.

    Aluminum Die Castings

    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

    Brass Sand Casting

    Brass sang casting, as the name suggests, involves the use of brass as the molten metal. Brass casting can be carried out by the way of brass sand casting only. Sand casting can be defined as a ‘casting part’ produced by formation of a mold from a mixture of sand and pouring the casting liquid (mostly molten metal) into mold.



    Brass is a great metal to cast with as it can provide some really great looking results.  Many believe that brass, an alloy of zinc and copper, has been around since our prehistoric ancestors. Today brass is used for a multitude of products from coins to trumpets not to mention a whole bunch of other musical instruments.

    Aluminum Sand Casting


    Aluminum casting Process are classified as Ingot casting or Mould casting. During the first process, primary or secondary aluminium is cast into rolling ingot (slab), extrusion ingot (billet) and wire bar ingot which are subsequently transformed in semi- and finished products.

    The second process is used in the foundries for producing cast products. This is the oldest and simplest (in theory but not in practice) means of manufacturing shaped components.

    Green Sand Casting

    These Green Sand Casting molds are made of wet sands that are used to make the mold&#039;s shape. The name comes from the fact that wet sands are used in the molding process.


    For a simple object—flat on one side—the lower portion of the box, closed at the bottom, will be filled with prepared casting sand or green sand—a slightly moist mixture of sand and clay。

    forms a "green" mold which must be dried to receive the hot metal. If
    the mold is not sufficiently dried a steam explosion can occur that can
    throw molten metal about. In some cases, the sand may be oiled instead
    of moistened, which makes possible casting without waiting for the sand to dry. Sand may also be bonded by chemical binders, such as furane resins or amine-hardened resins.

    Metal Casting Processes

    There are various casting processes being implemented now days. The oldest amongst them is sand casting. Spin casting is also widely used. They can be described as follows:



    Sand Casting
    : Sand casting involves formation of mold from a mixture of sand and to pour a casting liquid, most probably, a molten metal into mold. The metal is then allowed to solidify and the removal of mold, takes place. Sand molding consists of two types: green sand method and air set method. The first one consists of mixture of clay, moisture, silica, and many other additives. The second one consists of mixture of dry sand and other materials, not moist clay. They are mixed with the help of a quick curing adhesive. The collective use of these materials is called 'air set'.



    At times, there is temporary plug placed to pour the fluid which is to be molded. Air-set molds usually form molds consisting of two parts-the bottom and the top. The mixture of sand gets tamped down after its addition. It does not generate any by-product. After the solidification and cooling of metal, the mold gets usually destroyed. This is because its removal involves a lot of breaking and cracking. The casting accuracy depends a great deal on the sand and the process of molding used. Castings composed of green sand result into formation of rough texture on casting surface, and this characteristic makes them easily recognizable. Air-set molds produce smoother castings.



    Many a times, the casting process results in losing of components of sand mixture. It is possible to reuse green sand by the way of adjusting the composition to get the lost additives and moisture replenished. The entire pattern itself is eligible to be reused for producing novel sand molds. The method of reuse can be continued for an indefinite period. In 1950, casting process got automated partially. They have been in great demand for developing production lines since then.



    Spin Casting: Spin Casting is better known as Centrifugal Rubber Mold Casting (CRMC). It implies utilization of centrifugal force for producing castings out of rubber mold. As a customary practice, a mold having shape of a disc gets spun through its 'central axis' at a pre-decided speed. The material used for casting is usually thermoset plastic in the liquid form or a molten metal. It gets poured into the mold through the opening at its centre. Corresponding to the solidification of metal, or the setting of thermoset plastic, the spinning of the filled mold takes place.



    Normally, organic rubber or vulcanized silicone is used as a mold-making substrate in spin casting. Vulcanization takes place in the middle of process of mold-making. After the successful completion of vulcanization process, venting and gating must be undergone by the mold. This implies carving of channels for ensuring proper material flow and air during the course of casting. A scalpel or knife is used to carry out the above two processes. The mold complexity is directly proportional to the time required in implementation of venting and gating.

    Sand Casting
    Sand Casting www.cnsandcasting.com is a process, which is used to make or manufacture large components and equipment made out of brass, aluminum, iron and bronze. The metal is first melted and then gently poured into a mould, which is made up of sand. In other words, sand casting, the most widely used forging 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.

    Sand casting is used to produce a wide variety of metal components with complex geometries. Sand casting is also common in producing automobile components, such as engine blocks, engine manifolds, cylinder heads, and transmission cases.

    Commercial Forms of Aluminum Alloys: Part One

    Mill products of aluminum vary from foil thinner than tissue paper to plate 6 in. thick, and from wrist-thick stranded electrical power transmission conductor to magnet wire finer than human hair.


    Ingot

    Ingot, from which all other aluminum products are made, is generally supplied in one of seven commercial forms.


    Unalloyed Ingot. Unalloyed aluminum ingot is furnished in sizes ranging from small-notched bars weighing a pound or less to large ingots weighing a ton or more. Unalloyed ingot may vary from about 98 to 99.999% Al; 99.5% Al is the most common grade. Electrical conductor (EC) ingot and rotor ingot for motors are special grades in which impurities objectionable for these applications are controlled.


    Rich Alloy Ingot. Although unalloyed ingot is often used as produced, it is more often necessary to alloy it with other elements such as chromium, copper, iron, magnesium, manganese, nickel, silicon, titanium, and zinc. To accomplish this easily in production, rich alloy ingot, or "hardener", is employed; hardeners contain from less than 1% to as much as 50% of alloying elements.



    Casting Alloy Ingot. Large quantities of scrap are consumed in the production of casting alloy ingot. When the impurity limitations on such alloys permit the introduction of large amounts of scrap, the resulting product is referred to as secondary casting alloy ingot. When the composition limits restrict the use of scrap, the product is designated as primary or virgin casting alloy ingot. There are many areas of overlap between primary and secondary.


    Extrusion ingot. Extrusion ingot is usually furnished in cylindrical form, both solid and hollow. It varies in outside diameter from 75 to 800 mm. This product is most often made by the direct chill (DC) casting process or by some modification thereof. It is sawed to lengths varying, conforming to the requirements of the press in which it will be extruded. With certain alloys, extrusion ingots are often soaked or preheated before shipment to the extruder. This treatment, sometimes called homogenizing, permits higher extrusion speeds, improved surface finish on the extrusions, and longer die life. When extrusions of the highest quality are required, as in strong alloy aircraft parts, extrusion billets may be scalped before shipment to remove surface liquation. Hollow ingots are used to extrude tube and other hollow shapes. These ingots are normally cast to the required dimensions in the direct chill casting machine, but manufacturing limitations often require machining of the inside diameter.


    Forging Ingot. Although most small forgings are produced from rolled or extruded stock, cast ingots are often used for large forgings. To prevent irregularities in the cast surface from affecting the quality of the forgings, these ingots are always scalped before shipment. Forging ingot is generally supplied in cylindrical form.


    Hot Metal. Molten metal is sometimes transferred directly in insulated ladles from the smelter to the customer’s plant, occasionally at distances up to several hundred miles.


    Castings

    In order of commercial importance, the three major forms of aluminum castings are: die, permanent mold, and sand.


    Die casting. Die-casting is inherently suited to large-quantity production of both ornamental and structural aluminum parts. If the quantity permits investment in a die, if wall thickness can be reduced as much as the casting process permits, and if objectionable undercuts are not present in the design, aluminum castings can usually be produced by this process at a lower cost than by any other method.



    Permanent Mold Castings. In the permanent mold process, cast iron molds and cores are generally used; less frequently, steel and inlays of other metals are employed. Molten aluminum is poured into the mold cavity under a normal gravity head. In special cases, a small amount of pressure is applied to the mold through the application of vacuum, by pumping the molten metal, or by centrifugal force. In the semi permanent mold process, cores of dry sand or other expendable material are employed, overcoming many of the design limitations imposed by metal cores. Permanent mold castings are metallurgically superior to die or sand castings, having greater soundness, pressure tightness, higher strength, greater speed of production, and thinner walls.


    Sand Castings. The sand casting process is the most versatile method of producing a cast aluminum shape and is characterized by universal adaptability. It is employed to produce small quantities of identical castings, parts requiring intricate coring, and very large castings. Modern high-speed molding equipment and methods produce sand castings relatively cheaply.


    Other Cast Forms. Direct chill castings -- both solid and hollow, having round, rectangular or odd-shaped sections -- are used because of their outstanding mechanical properties after heat treatment and their sound structure. Mechanical properties approach those of wrought products except that the elongation is lower. Cast tool and jig plate and large sizes of cast bus bar are commonly made by this process. When thin walls and close dimensional tolerances are required, and if the quantity does not warrant die-casting, shell mold casting, plaster mold casting, or investment casting are often employed. The last two processes are also used where difficult undercuts and intricate coring are required. The centrifugal casting process is used for the production of large aluminum alloy tubes and rings.


    Forgings and Pressings

    Aluminum alloy forgings and pressings are produced commercially in conventional hammer equipment, on hydraulic and mechanical presses, in ring rollers, and on upsetters. They may be classified as die forgings, hand forgings, and rolled rings.


    Die Forgings. Depending upon the amount of machining necessary to obtain a finished part, aluminum die forgings and pressings are categorized as (a) blocker, requiring the most machining; (b) conventional, providing a good balance between die cost and machining cost; or (c) precision forgings and pressings. Precision forgings are of advantage where it is desirable to obtain thin web sections and thin, accurate ribs with a minimum of machining. Draft angles are controlled to less than 10 if desired; corner fillets can be held to a minimum.



    Hand forgings are produced by working aluminum stock between flat dies or other simple tools that shape the piece roughly to the required contour. Prototypes are frequently made as hand forgings to reduce delivery time. Slabs as large as 7 in. thick by 120 in. wide and 450 in. long, weighing over 35,000 lb, are available in the form of hand forgings.


    Rolled Ring Forgings. Precision ring rolling equipment is available to produce rolled rings in a wide range of diameters up to 150 in., in any wall thickness and alloy. Larger rings can be fabricated by forging over a mandrel.

    Green Sand Mold process
    The Sand Casting process - aka Green Sand Mold process - is commonly used in the casting of aluminum, brass/bronze, and iron products.


    The term “green sand” is known principally because of the moisture content within the sand. The sand undergoes a “mulling” process in which various clay and chemical additives that act as binders are blended with the sand, which results in a compound which is suitable for the sand molding process.


    This prepared sand mixture is then compressed around the pattern at specific pressures and temperatures, to ensure it will maintain its shape throughout the remainder of the casting process. The blended sand and binders are compacted around the pattern, taking on the shape of the desired casting.


    Sometimes the design of the casting entails internal passageways being formed into the mold. This is done by using sand cores which are made of a similar sand mixture. The cores are strategically placed to form the necessary passageways in the casting. The two halves of the mold are subsequently closed and metal is poured into the cavity and left to solidify.


    After solidification has taken place, the sand is vibrated until it is released from the casting. The finishing process can then be completed by grinding, machining, plating and painting.
