Each project and each venture requires a different kind of casting and your project to be perfect; you will need to choose the right casting company. For the best possible customizations, detailed specific

s and more, make sure you pick the company that yields maximum benefits for you. There are some key factors to be kept in mind when you negotiate, choose and bid for the right casting company. This article aims at helping you with those so that you don’t fall prey to unfortunate mishaps during investment casting foundry.

• Involvement and no quality compromises should be on the top of your priority list while choosing. Quality of casting will determine longevity of life of your projects. It is essential for the casting company to show interest and be involved in your endeavor from the very beginning.
• Choose a company that invests time to understand your demands and is sure that it can deliver fully to cater to your needs. If you come across a company that hurries too much and is not sure about delivering the best, do not choose them.
• Do your research well and choose from amongst a variety of companies. When you bid and tell them your needs, through your interaction you will figure out how much time each is willing to invest in looking into details. Remember, it is always better to be safe than sorry.
• Transparency and communication is very important. If you do not receive a very detailed bid from the company of what you need and what you’ll get, choose a different company. If something is not mentioned properly, ask for clarifications.
• Communication from your end is important too. Provide visual details, graphical representation and drawings as much as possible of your venture so that the company has a detailed idea about the kind of customization needed.
• Check out reviews, especially about timely delivery. Delivery being postpones and then leading to unsatisfactory projects are common and the best way to avoid that is looking out for trustworthy reviews about the company’s timely delivery.
• Advanced demands from your end are absolutely okay as long as you specify the volume you require as well as add on elements. Add ons would essentially include pain, galvanization and others.
• A pattern or a prototype of the object which is to be cast is very important too. This involves details about the pattern, material of the pattern, life cycle of it and other details. Faulty patterning can severely hamper the final product. Your bid must clearly indicate pattern requirements along with type and cost too.

No matter how much research you do, the final product is a matter of luck. However, doing your research well about the company and investment casting foundry can keep many misfortunes at bay. Clear out all the terms. Communicate and interact well before finally choosing and investing. Ask if the company has worked on similar projects before and look for testimonials. Get a comprehensive schedule and time of delivery.

Need To Know About Pressure Relief Butterfly Valve Castings

Pressure relief butterfly valves are flow controlling devices which isolate or regulate the flow of any fluid. Its closing mechanism is a rotating disk, unlike the ball valve. With its expanding usage throughout different industries, butterfly valve castings are very high in demand, globally. So, let’s take a quick look at the basics of these valves to understand their relevance.

How does it operate?

The basic principle of operation is identical to that of a ball valve, which allows for a quick shut off of flow. But usually people are more biased towards the former because of their comparatively lower cost than the latter. In addition, butterfly valves are lighter in weight, hence requiring much less support. A butterfly valve’s basic functioning design is:

• A disc is placed at the centre of a pipe.
• A rod passes through that disc to an actuator placed outside of the valve.
• By rotating the actuator, the disc can be turned parallel or perpendicular to the flow.
• Unlike the ball valve, due to the constant presence of the disc within the flow, there is a pressure drop induced even when open.

The butterfly valve belongs to the group of quarter-turn valves. While operating, the valve completely opens or closes with the rotation of a quarter turn of the disc. The “butterfly” comprises nothing but a disc made of metal, which is placed on a rod. The disc is twisted at the time the when the valve remains closed and this ends up blocking out the passageway, whereas, when completely open, the disc on the valve gets a quarter turn rotation, to allow the fluid flow in an unhindered manner. The valve can be opened in a gradual increasing method, to enable throttle of the flow.

Different Kinds of Butterfly Valves

There are different kinds of butterfly valves available to suit different pressures and usages. The most common kinds are-

• Wafer-style butterfly valve: This type of butterfly valve has a designed to keep up a blockage against pressure gap that is bi-directional, to stop it from flowing back in systems that are meant to have unidirectional flow.
• Lug-style butterfly valve: In these types of valves, both ends of the body have threaded inclusions which enable installation of the valves into a system that has just two bolt sets, without any nuts. This setup allows either sides of the piping arrangement to be disconnected without affecting the other side.
• Rotary Valve: These kinds of valves comprise a variation of the basic butterfly valve where pockets are included in the butterfly as an alternative to being flat.

Usage of Butterfly Valves in Industries

• Butterfly valves are frequently used in the chemical, pharmaceutical as well as the food industry.
• These valves are also used by firefighters on their hoses to limit their pressure.
• These are also abundantly used on front and rear suction ports, tanks and water pumps.
• In case of specific valves, it is possible that the valve may perform additional functions; e.g.-cast iron butterfly valves not only act as a regulatory device but can actually stop and start the flow as desired.

Due to its low cost, high functioning and simplicity of installation, butterfly valves have been replacing ball valves in their several usages (like the petroleum industry). But it is important to make sure that the valves used in these industries are manufactured according to the CGMP (Current Good Manufacturing Practice) guidelines. In different industries, butterfly valve castings are preferred and appreciated alike, by virtue of their efficiency and simplistic design.

A Comparison Between Butterfly Valve and Ball Valve Castings

The butterfly valve and the ball valve are the two most commonly used valves in the industrial sector. The two have many similarities and dissimilarities. While they look very different from each other, both of them tend to perform very similar fu

nctions. This article about ball valve castings and more will bring to you a comparative study of the ball valves and butterfly valves.

The similarities:

• Both of them are essentially made by combining a variety of different metals like stainless steel, brass and cast iron.
• Both of them are very commonly used because of their high durability and shelf life.
• Both of them are also economical, which makes them always be high on demand.
• Both of them can be used at different temperatures for the regulation of flow of a variety of gases and liquids.

The differences:

• The construction and look of the two valves are vastly different. The ball valve castings have balls with holes through them. The butterfly valves on the other hand have disks mounted on rotating shafts.
• The working procedures of the two are also different. The ball valve opens, blocks or partially opens a hole in the ball to control and regulate the flow. The disk is what the butterfly valves use. The handle is used in the latter case to turn the disk by ninety degrees to either let the flow completely through or to completely block it.
• The pressure drops involved with the two valves are different in nature. In the ball valves, there is hardly any difference in pressure and that is a huge advantage. The ball valve will turn no matter how much pressure is being exerted from the end of the supply unit. However, the same is not true for butterfly valves. In this case, with the interfering nature of the disk, there is always a drop in the pressure. This can go on to have serious problems later on.
• In the sector of uses, both have their own advantages and disadvantages. Ball valves are better overall but more expensive. They are most commonly used for the flow of gas. This is because they have a better sealing mechanism with very low chances of leakage.
• On the other hand, butterfly valves are economical and boast of low maintenance. They are used for public services like municipal water projects and sewage control. Even projects that involve redirecting or controlling the flow of streams or rivers, butterfly valves are the chosen options.

A careful inspection of both must be done before you choose to use one for your necessity. Understanding the structure and function of both is necessary to pick the perfect valve for the function you need it to perform. Ball valve castings as well as butterfly valves are available widely and easy to procure. You should feel free to contact a trusted manufacturer who can explain and choose the best suited valve for you. Do your research well before investing as it always better to be safe than sorry.

How to Check Mechanism and Benefits of Check Valve Castings

Valves that are known as non-return valves, one way valves, and clack valves are all the same type of valves. As defined by the check valves casting, these are all the different names of the same valve, popularly known as the check valve.

Operation of check valves

Check valve is completely different from other types of valves. Their major ability is passing the fluid in any one direction and in that direction only. This function is greatly helpful for a number of applications, especially when it concerns the prevention of overflow.

It is important to understand how these valves function first and foremost. Check valves operate usually on a two port system. It has an opening to allow gas to be drawn to the first port. This gas is then transferred with the help of a mechanism that separates the two different types of port.

These ports help in drawing the water from the first port to the second port. This water is then pushed out with an opening, blocking the fluids from reentering the first port.

Different kinds of Check Valves

Now, let us briefly know about the different types of check valves available in the market. There are many types of check valves that are common in the industry: swing check valves, disc check valves, split disc check valve, diaphragm check valve, and wafer check valve.

Swing check valves are common valves, used in toilet tanks present in houses and so on.  There are no balls controlling the flow. This valve uses small door on hinges whichis forced opened when the water or other fluidsare drawn. It closes when there is enough water, thus preventing the drainage of water from entrance of the valve.

Disk check valves are a bit more complex valves that have a disc which is mounted on a spring for functionality. The pressure forces the inlets to open up, as it stretches the spring. When the water flow stops, the compression of the spring is great. This causes the disc to return to the initial position.

Split disk check valves or dual plate check valves have a door split in the middle. This door regulates the flow of the liquid in one direction only. The fluid causes a pressure that enables the hinges to open.

Diaphragm check valves have flexing rubber mechanism. This helps in the regulation of the flow of liquids. It helps in activating a certain pressure on the upstream side of the valve, pushing out the fluid.

Wafer check valves can usually work with swing, disk check, split or any other mechanism. It is usually smaller in size and can be fitted between flanges.

Benefits of Check Valves

There are several benefits to check valves. A few of the more pronounced ones are:

• Protection of pumps and compressor equipment from damage and flows in the wrong directions.
• Reduction

  

  of time taken and loss of production of liquid for unsuitable valves.
• Increase in the energy savings due to lower pressure.
• Prevention of water hammer in check valves.

Check valves in check valve casting are casted to have smaller footprint and reduces the possibility of sudden failure in valves, making them cheap and effective for longer runs.

An iconic addition in the pumping industry - Submersible pumps

It needn’t be stated that water forms is fundamental for our existence and without a doubt, the most essential amenity that we require to survive. For those of us loving in the cities and metropolitans or even the outskirts, we know the importance of a good and efficient pumping system. We are so used to having this very basic amenity just a lever away that we often take it for granted. The easy availability of modernized pumping systems for our homes and offices has made our day to day lives a whole lot easier.

Acquiring water stored underground and converting it into water that is fit for consumption may seem a simple process, one we hardly ponder over. Yet, it is one process that requires the state of the art technology and skills. At present, submersible pumps are the new in thing. As a matter of fact, submersible pump parts casting have revolutionized the pumping system across the globe. Let’s learn more about it.

What are submersible pumps all about?

A submersible pump also goes by the name of utility pump and that is how it is known worldwide. Also, submersible pumps are electrical

devices which are airtight usually. These pumps are used to empty and drain the accumulated water in your offices and homes. The motor in the case of a submersible pump is sealed and attached to the body of the pump. The motor has been designed in such a manner that it is durable and able to withstand the pressure of the water pumping process everyday – both from outside and within the surface of the earth.

In the case of submersible pumps, there are a few major components which must be taken into account. They are – expulsion flow, pumping pressure, horsepower, discharge size and the maximum discharge. Like all other pumping systems, you will have to be cautious while maintaining the submersible pump in order to prevent any kind of leak or damage. Moreover, these pumps come in numerous shapes and sizes depending upon the nature of function they are supposed to perform. In most cases, pumps with half horsepower are more than enough, but if the water levels are lower, you would require pumps with higher horsepower.

Why should you go for submersible pumps?

Now the question might arise, why go for submersible pumps when the traditional pumping systems are working just fine? Here’s why:

• Submersible pumps are not dependent on outer air pressure. That makes it all the more flexible and allows it to suck in more power.
• Also, the pump comes with advanced mechanical seals which are highly efficient when it comes to preventing any kind of a leak. Leaks are always dangerous in the case of any electrical device, since it may lead to a short circuit.
• They are relatively low maintenance and are ideal for heavy duty work.

What is the Lost Wax Investment Casting Process?

The lost wax investment casting process refers to a procedure where casting of a replica sculpture can be done from a sculpture that is original. Known by a variety of names such as investment casting, precision casting and “cire perdue” (French), the oldest artifacts made from the lost-wax casting proc

ess date back to 4500-3500 BC in Israel. Other than that, artifacts have also been found in other parts of the world. Although the procedure has been modified according to recent times, and varies according to foundries, the traditional methods are still preferred and the steps are standardized.

1. What’s the process behind lost-wax casting?

The casts are made from a copy of the original model, which could be made clay that is oil or wax-based. The moulds have outer and inner moulds, into which molten wax is poured to create an even coating over the inner surface. The outer mould is made from plastic or fiberglass, while the inner mould is made out of polyurethane rubber, latex, and silicone. Moulds mostly consist of two pieces along with a shim containing keys, which are required to reconstruct the original sculpt. After the poured-in wax cools down and hardens, the mould attains the preferred thickness.

The wax model is then removed from the mould, which may be used for making multiple models. A heat-resistant mixture is then poured into the mould to blend out any defects, and the shell is secured with many layers of the plaster. Other molded pieces are now attached to the main body. The model is inverted and baked in a kiln, which dries out the plaster and the leftover wax runs out.

After removing remnant moisture, the shell is then packed with sand and molten metal is poured into it. After it has cooled down, the shell and the core are removed which reveals the original casting. The metal is now “chased” to blend out flaws, and the casting now looks identical to the original model. The final casting is filed down and finishing touches are added as needed.

2. What are the other uses of lost-wax casting process?

The lost-wax casting process has been used by foundry-men and artists to make intricate sculptures, ornaments and automobiles for centuries. Apart from this, the process is also popular for making casting jewelry, brooches, buckles and other small parts needed in various industries. Lost-wax casting can also be seen in textile use, where the wax and textiles are replaced by metal when casting. Due to fabric reinforcement, the model is thinner which reduces the amount of metal used in the mould. 

3. What are the advantages of the lost-wax casting process?

Despite modern ways of casting, foundry-men and artists still prefer the traditional methods of casting. Some of the advantages include –

1. The lost-wax casting process can be used on any material that can melt burn and evaporate to leave behind a mould cavity.
2. The duplicate model will reproduce even minute details of the original sculpture.
3. Allows for unique shapes of casting that would be impossible in other methods.

Therefore, the Lost wax investment casting process is a seasoned method for the reproduction of various objects. However, the procedure does have its disadvantages such as the initial cost, need for large machinery and the particularity of holes in the mould. Therefore, it is important to look for expertise, design, performance and cost to get the best quality at the best price.

Benefits of using stainless steel in pumps

If you were to name one of the most important amenities in your homes or offices, what would it be? Electricity? Food? You’d probably say water, since it’s impossible to imagine life without it. In order to ensure that you receive a steady and interrupted flow of water throughout the day, homes and offices usually come with pumping systems which are required for our day to day lives. Now have you ever wondered what these pipes are made of, or how they work? We usually take these systems for granted; but the truth is, they’re indispensable. It would do you good to know your basics and have a sufficient knowledge of how pumps work.

Now traditional pumps are usually made of bronze. Since time immemorial, bronze has been considered to be the standard metal since it is rust free, durable and strong enough to withstand the rigor and pressure that comes with pumping. But in the recent past, research has proven that stainless steel is equally good, if not better. Owing to this, stainless steel pump casting has recently gained in popularity. But before you change your traditional pumping system, it’s important to consider the pros and cons.

Benefits of using stainless steel in pumps

Now bronze is definitely a good choice when it comes to pumps; however, it is not as resistant to corrosion as stainless steel. Let’s take a look at some benefits of using stainless steel over bronze:

• As it turns out, the properties of stainless steel as a metal makes it immune to corrosion and rusting. Over time, bronze becomes vulnerable to corrosion, and once it is corroded, it becomes unfit for use since it may lead to leaks. You always want to go for a metal which is long lasting and will stand the test of time. Stainless steel too would be subject to corrosion, but it certainly lasts longer than bronze.
• Stainless steel would improve the surface performance of your pump, thus making it more energy efficient and enhancing the overall performance of the pump. Also, it would pave the way for sustainable performance of hydraulics.
• It is also resistant to chemicals and has lower degradation potential. That makes the pump all the more efficient.
• Speaking of application flexibility, it is much higher than that of bronze pumps.
• With bronze pumps, you’re going to have to spend a lot more on maintenance in order to prevent ruptures and leaks. However, stainless steel is relatively low maintenance. Since it is much more durable and immune to corrosion and, it wouldn’t require too much of an investment.
• Stainless steel pumps come with excellent formability. They are also easy to weld, making installation much easier. Plus, these pumps are comparatively easier to fabricate.
• In harsh environments, you need pumping systems that are adaptive and versatile. Bronze pumps being traditional and old school do not offer such benefits. This is where stainless steel pumps come in handy.

All about the Aluminum Investment Casting Process

Aluminum manufacturing is one of the most profitable manufacturing processes in this day and age. Investment casting foundry India claims that the manufacturing of aluminum for several uses in almost all aspect of life is one of the oldest metal working processes in the world.

This manufacturing process has not changed at all for over a hundred years and the industry is still growing at a rapid pace.

This process of metal working dates back to five thousand years ago. It was used to produce bronze and copper for pots, vessels, weapons and tools, gold jewelry and statues for decoration and personal use. This process was created by ancient civilizations of Mesopotamia, Egypt along with the Han Dynasty of China and the Aztecs.

There were several processes involved in the investment casting, such as:

• The lost wax casting was done with the use of bees wax for making a particular pattern while it was in liquid form.
• The wax was allowed to harden over time, away from the sun to get the best shape for the final casting.
• After the wax was hardened it was dipped in molten metal to have the final shape.

The earliest process recorded goes back to 1100 AD which speaks of a sculptor named Benvenuto Cellini molding a statue after the Greek Hero Perseus holding the head of Medusa.

Despite the process being old, it requires high tech advanced metal forming techniques that are bound to produce a higher quality and quality of metal and metal parts. Investment casting is a one on one process that creates one wax per metal part.

Because it is flexible and ever changing there it can develop a lot of complexities that need to be solved in order for it to run smoothly. With the correct casting methods however a large amount of metal works can be produced in a short time.

In this day and age with technological evolution, we have managed to create superior machines that make the process of aluminum investment casting easier, reliable and really effective with features such as quality control equipment, computerized processes, waxes, and refractory materials.

Modern day aluminum casting is used for several benefits, such as the fast and reliable creation of metal parts and metal components that cannot be produced with the use of the normal manufacturing processes.

A good example of using this type of casting is the creation of planes that carry several passengers but need to be as lightweight as possible. These large metal parts cannot be processed by regular methods and therefore investment casting is highly preferred for its precision and easy execution of the metal working process/

Apart from this, metal investment casting can be used to manufacture components such as sand casting, forgings and welded fabrication castings. Investment casting is popular because it is known to reduce the cost while improving the quality.
