Why Choose a Horizontal Centrifugal Casting Machine Manufacturer over a Vertical One

 While thinking about centrifugal casting, people usually think about either vertical or horizontal casting, not both. A basic question people ask is why they should choose a horizontal centrifugal casting machine manufacturer over a vertical casting machine maker and vice versa, and how to know which casting type is best for the machine parts.

Usually, a common foundry man might believe that the centrifugal casting procedure is simply used for cylindrically shaped parts like liners, tubes, sleeves, pipes, or rolls. However, this is not true. These shapes are usually cast using the horizontal centrifugal casting technique. The non-cylindrical-shaped parts, such as gear blanks, sheaves, valves, and sprockets, are ideally cast using the vertical centrifugal casting technique.

Why Use Horizontal Centrifugal Casting over Vertical Centrifugal Casting?

Ideally, horizontal centrifugal casting is best implemented for castings of greater length than diameter that feature a cylindrical bore. For this reason, you will generally find tube shapes between 12" and 20’ long cast horizontally. On the other hand, vertical casting is generally used for cylindrical shapes where the diameter exceeds the casting’s height or length, such as bearings or rings. Moreover, other specialty castings like ball valve balls and conical-shaped castings are also cast via the vertical centrifugal casting method.

Both vertical and horizontal casting methods can be utilized with non-ferrous and ferrous materials. The machines are not aware of the material being spun. It is through applying several methods, like water cooling duration and rates of spinning and pouring, that several materials, like cast iron and copper, can successfully be poured into similar kinds of quality castings and devices.

Horizontal and vertical castings differ not only in shape but also in how the molten material behaves in the device. Although both horizontal and vertical techniques use centrifugal force, there are some distinctions in how the pressure is applied regarding the axis of the mold rotation and the speed of the molten metal with respect to the rotating mold.

For instance, using a vertical mold axis, the ultimate force on the liquid is continuous. The same is not the case in a horizontal mold. The other distinction between vertical and horizontal mold orientations is the speed gained by the molten metal as it spins around the mold. When the manufacturer pours metal into the horizontally rotating mold, significant slip occurs between the mold and the metal. Therefore, the metal doesn’t move as quickly as the rotating mold.

To overcome this inertia, the metal should be sped up to reach the speed of mold rotation. This is not an issue in the vertical centrifugal process, where the molten metal reaches the mold speed soon after pouring. However, using a vertical mold axis, there is scope for the molten metal to create a parabolic shape because of the competing centrifugal and gravitational forces.

Conclusion

Both devices can provide a semi-manual setup in which cycle times are heavily influenced by operator speed, all the way up to a fully automated device in which an operator uses one or more devices in a high production setting. Centrifugal Casting Machine Company is a vertical and horizontal centrifugal casting machine manufacturer that delivers a complete range of both types of devices and can help you decide which type is best suited for your requirements.

What to Know Before Choosing a Vertical Centrifugal Casting Machine Manufacturer

The methods utilized for molding and shaping metals have transformed vigorously over the centuries. Sand casting, forging, and welded and rolled processes are some of the conventional techniques used for making metal parts and elements. However, there are several applications where these fabrication techniques are not effective or suitable. A vertical centrifugal casting manufacturer can manufacture components with intricate geometries at a reasonable price and with decreased machining needs compared to other casting manufacturers.

The centrifugal casting process involves pouring molten metal into the center of a rotating mold. The rotation induces centrifugal force and pushes the molten metal against the mold’s inner wall to make the desired shape. The molding dies can be oriented vertically or horizontally.

When Is Centrifugal Casting Appropriate?

Centrifugal casting has traditionally been utilized to create hollow shapes with particularized thicknesses in the places where the end product needs the densest and best material on the product. Because of its operation mode, centrifugal casting is highly suitable for elements with axisymmetric geometries. An advantage of this technique is a reduction in instances of retained porosity or air pockets in the ultimate product.

Centrifugal casting is well-suited to apparatus that requires extreme precision because it is done with a pre-determined mold size and controlled electronically. Products with exact weights and dimensions can be produced to strict tolerances by controlling the casting procedures with computerized controls.

Although most usually related to molten metal, there are centrifugal casting benefits when utilized with virtually any material that can be melted into a pourable slurry, including plastics, ceramics, glass, and concrete.

The Process of Vertical Centrifugal Casting

The vertical centrifugal casting method contains many phases. At the starting point, the molten metal is poured into a vertically oriented, preheated, rotating die. Then the centrifugal forces in the vertically spinning mold lead the molten metal to spread vertically and horizontally along the mold’s inner diameter so it can assume a particular shape.

Since the die and mold spin, the denser components of the molten metal are forced towards the outer diameter. The mold acts as a cooling surface in a directional solidification process, which solidifies the metal from the outer diameter as it shifts towards the bore. This method causes impurities to float toward the inner diameter. When the casting procedure is completed, they can be machined away.

The outcome is an ultimate product with exclusive mechanical properties and a finer and more uniform grain structure. This is why vertical centrifugal casting methods are used to make elements for aerospace, aviation, petrochemical, military, and other industries that need high-end elements.

Although both vertical and horizontal casting can create the same quality products, vertical casting orientations are more convenient for cylindrical shapes with a diameter many times larger than the height or depth of the cast. The examples of products best suited for vertical centrifugal casting are bearings and rings.

Vertical centrifugal casting can be utilized to cast non-cylindrical parts like propellers and valves by utilizing specialty castings. Other commonly created products with vertical centrifugal casting techniques are sprockets, flanges, short bushings, gear blanks, and balls for ball valves.

Things to Consider While Choosing a Centrifugal Casting Machine Company

The procedure of choosing the right centrifugal casting machine company must not be the same a selecting a supplier for manufacturing equipment, bolts, or office supplies. Although some may treat centrifugal castings as a commodity, they are far from it, and the procedure of choosing the right manufacturer for a particular application needs cautious consideration.

The qualification of the supplier is the most essential part of the buying process. Usually, a buyer’s main responsibility is to find responsive and qualified suppliers. However, in a few cases, buyers think that a supplier willing to contractually fulfill their buying needs is qualified. However, using unqualified suppliers and low-cost products can lead to quality issues and wasted money and time in the future.

To help you understand the process, here are a few things to ponder while choosing the right centrifugal casting machine supplier:

1. Price, Product Quality, and Service

While choosing a centrifugal casting machine manufacturer, careful consideration must be given to price, product quality, and service. Think about what is essential for you, noting that many companies are acceptable in every area but can possibly excel in just one. For instance, if the lowest possible cost is mostly necessary, the supplier will likely not be the best-in-class in product quality and service.

2. Experience in the Market

While choosing a casting machine company to work with, decide whether they are experienced. A centrifugal casting supplier that fully understands your products, applications, pain points, and terminology can predict possible issues and requirements. This is particularly essential in high-compliance markets. The good news is that authentic centrifugal casting machine makers publish their basic markets on their websites, making it convenient to decide while choosing a supplier.

3. Machining Capacities

Purchasers usually choose centrifugal casting suppliers who have machining capabilities. This prevents problems if deflects are observed during machining. If a third party is causing the problem, it may be possible to determine who is to blame. Is it a machining problem or a casting problem? If the supplier finds a problem during machining, the issue is solved quickly without any dispute over whose fault it is. The company owns it, so there is less time required for processing, shipping, and replacing or exchanging. Also, integrated machining eases the supply chain and lowers handling time and shipping expenses before the product makes it to the consumer.

Bottom Lines

As earlier mentioned, the process of choosing the right centrifugal casting machine company needs you to consider some points carefully. Make sure you consider the points discussed above so you can decide on the best supplier for your requirements. Centrifugal Casting Machine Company, Inc. is a world-class leader in centrifugal casting and permanent mold technology.
