Gray iron castings provide durability, hardness and strength to any operation in which they are used. There are many applications for gray iron castings. As non-combustible building elements, they provide excellent fire protection for wooden support structures. Additionally, their graphite/graphite flake content can be used for energy dissipation in components such as engine blocks and crankshafts, which depend on the damping of mechanical vibrations.
Gray iron castings are frequently used in the manufacture of: valves, housings, engine blocks, molds, pump casings, pipes, brake drums, trim and gray iron cookware.
Benefits of gray iron castings
Gray cast iron has many advantages. First, it imparts high damping capacity, compressive and tensile strength to the product. Second, it's quick and easy to produce. Also, due to the presence of graphite and graphite flakes, gray cast iron has good machinability and weldability. With it, cast iron foundries can create a wide variety of complex shapes. Additionally, the gray iron casting process produces less shrinkage during cooling than similar casting methods. This means that castings require little secondary machining. Best of all, gray iron castings are relatively cheap, so investing in them won't break the bank.
Gray iron castings do have a disadvantage in that they are not shock resistant and will shatter instantly with sufficient force.
Bronze is one of the oldest types of metal discovered by man. It is known to have existed around 3500 B.C. and first used by the Sumerians in Western Asia. Bronze is an alloy that is traditionally made up of copper and the metal tin. The ratio between copper and tin varies from one metal to another, however, recently, one can only be considered bronze if it’s made up of 88% copper and 12% tin.
Liquid bronze is created by melting copper and tin and mixing them. Bronze casting is the process wherein the molten bronze is poured into a mould created based on the model sculpture. The creation of the model and the negative mould is the first steps in the process of bronze sculpture production. The bronze is then let to cool down and harden for at least three days. Once it’s done, the shell or the negative mould is shattered to reveal the sculpture.
Die casting is an efficient and economical process that enables a wider range of shapes and components for the automotive industry and other applications than any other manufacturing technique. Parts are long-lasting and can be designed to complement the visual appeal of surrounding parts. Automotive part designers can gain many advantages and benefits by specifying aluminum die cast parts.
High Speed Production - Die casting is capable of producing automotive parts with complex shapes and with tighter tolerances than many other mass production processes. Little to no machining is required, and thousands of identical automotive die castings can be produced before the mold is repaired.
Dimensional Accuracy and Stability - Die casting produces automotive parts that are durable and dimensionally stable while maintaining tight tolerances. They are also heat resistant.
Strength and Weight - Thin-walled castings of die-cast automotive parts are stronger and lighter than castings produced by other casting methods. In addition, since die castings are not composed of separate parts that are welded or fastened together, the strength of the automotive part after die casting is that of the alloy, not the joining process.
Multiple Finishing Techniques - Die cast automotive parts can be produced with smooth or textured surfaces and can be easily plated or finished with minimal surface preparation.

Investment casting can be used to customize a wide variety of metal components for industries such as medical, construction, mining, forestry, automotive, and more. Like other industries, agricultural machinery is one of the main fields of application of precision castings. Investment castings for agricultural applications account for approximately 20% of all investment castings in our investment casting company. This shows the important position of investment castings in the manufacture of agricultural equipment.
We often refer to "agricultural castings" as agricultural wear parts or farming implements. In order to maximize the accuracy of agricultural investment castings, such products are designed and produced in precision investment castings. Importing precision castings from Chinese companies has many advantages such as low cost, convenient delivery, and good quality. All of these factors attract our customers to purchase agricultural parts from our investment foundry. CFS Foundry can provide investment castings in materials with good wear resistance. What's more, we can make farming tools with tungsten brazing or ceramic tiles. We can produce agricultural investment castings for:
tractor
Harvester
planting equipment
sowing equipment
farming equipment
etc.
With the exception of some standard castings, such as teeth and adapters, most investment castings are custom metal parts. So, no matter what kind of agricultural component you are looking for, investment casting is always the ideal method of manufacture. We can make agricultural castings in any shape you like.
Almost all agricultural components must be wear resistant. For investment casting, we can choose metal alloys with good wear and corrosion resistance. The most widely used casting alloy grades are ASTM 4140, ASTM 8630, AISI 1045, etc. In addition, heat treatment also helps to increase the hardness, which in turn increases the wear resistance of the product.
Some agricultural components are brazed with tungsten. For such products, the surfaces to which the tungsten carbide will be brazed must be machined. We can only leave a small processing allowance, which not only saves processing costs but also saves time.
Water glass casting is very similar to investment casting (i.e. lost wax), but is particularly suitable for larger castings and is less expensive to produce. The process provides a surface finish and dimensional accuracy far superior to sand casting, and more complex shapes can be achieved. In addition to steel, alternative materials such as iron and SG iron can also be cast using this method.
The difference between lost wax and water glass casting is simply the way the wax is removed from the ceramic mold:
Investment casting uses a high temperature autoclave to melt the wax, and in water glass casting, the mold is dipped in hot water to remove the wax. The wax then melts from the mold and floats on the water. This then allows it to be skimmed off and reused for waxing purposes.
Obviously, this also offers environmental advantages, and the wax is fully recyclable.
Advantages of water glass casting:
Better surface finish than sand casting.
Higher dimensional accuracy than sand casting.
Realize more complex parts.
Larger parts than traditional investment casting methods.
Cheaper than investment casting.
More metal options.
environmental advantage.
Casting tolerancedepend on the casting material and the production method used. General tolerances for metal alloy castings are specified by the International Organization for Standardization in their standard ISO 8062 for SG cast iron castings, manufactured using machine-produced sand molds. Suitable grades are Casting Tolerance (CT) 8 to 12. The capabilities of our green sand plant allow us to provide CT8 grade castings. The hand-produced castings are CT9 rated.
Closer tolerances may be available in certain cases.
The sand casting process has many advantages, especially investment casting, another popular casting method (to learn more, read our article on investment casting). This section will briefly explore why sand casting is so widespread in the industry, and its shortcomings as a manufacturing method.
The main advantages of using sand casting are as follows:
Sand casting can be used to make parts of almost any size, from triggers to engine blocks - if the correct mold is made, there is no limit to the size of the part required
Sand casting can produce very complex parts if the correct core/gating system is used
The process is highly adaptable and can be implemented in mass production of parts
Almost all types of alloys can be cast as long as they are molten and pourable
Low cost of equipment as it usually only involves sand and reusable patterns
Short lead times for making molds make sand casting ideal for short runs
Sand casting has low set-up costs and cost-effective modifications
The main disadvantages of using sand casting are as follows:
Sand casting creates a high degree of porosity in the metal, resulting in low final part strength
The surface finish of the mold is poor and must be cleaned
Castings have lower dimensional accuracy due to poor surface finish and shrinkage of the metal after cooling
Sand casting does not prevent defects, so cleaning must be done and can be time consuming
Sand castings with low tolerances must undergo some secondary machining
So, while sand casting may be a cheaper alternative to investment casting and can provide more complex shapes, more effort is required to achieve the same precision, finish, and overall part quality.
Application of sand casting
It is difficult to grasp how many different techniques use sand casting. Its versatility as a casting process makes it ideal for almost any complex part, and nearly all modern technologies benefit from this manufacturing process. Below is a list of just a few products manufactured using the sand casting process, showing how wide the range of possible applications is.
Sand casting is used to manufacture the following products:
Various pistons and valves
Blower/Impeller
Cams, Bushings and Bearings
Electronic equipment
Gas/Oil Tank
most hardware
engine block
car parts
Screws, Nuts and Gears
agricultural machinery
medical equipment
mining equipment
and more.
While far less precise than investment casting, sand casting is a low-cost, low-complexity manufacturing process that has repeatedly proven itself to be an integral part of modern manufacturing. If investment casting is too tedious, or if large parts are required, consider implementing sand casting in your production line.
