As the mold production for sand casting is a highly complex four step process, we’ll discuss each step in a separate blogpost continuing with the second step of the production which is the casting process design.

After having found the right mix for the molding material, the design of the casting process can start. This design is based on various factors, including the quality requirements of the castings, the production batch, and the production conditions. To optimize the casting process design, the following points are crucial:

• Understanding customer needs
• Familiarity with the existing production conditions and equipment options
• Economic analysis of products
• Energy-saving and environmental protection

Casting is a manufacturing process with a great history. Already almost 6,000 years ago, humans casted simple jewelry, tools, and many other things.

Today, we use casting to manufacture highly complex parts, but the basic principle has always remained the same: molten metal is poured into a prefabricated mold resulting in a predesigned shape after solidification. These prefabricated molds often don’t get the recognition they deserve. This blogpost sheds a light on the mold production for sand casting. As this is a highly complex four-step process, we’ll discuss each step in a separate blogpost starting with the first step of the production which is the preparation of the molding material.

The importance of the right type of sand

To meet the high demands of sand casting, a special type of sand for the mold production is required. So-called raw sand is used for the mold because it mostly contains quartz, which has a high melting point of 1713 ° Celsius and a high hardness. These characteristics make raw sand well suited for casting thanks to its high wear resistance and high temperature resistance. When selecting raw sand, the amount of quartz should be as high as possible.

The first patent on a centrifugal casting process was obtained in England in 1809 and 40 years later, centrifugal casting was first used in Baltimore to produce cast iron pipes.

Nowadays, centrifugal casting is mainly used to manufacture cylindrical components of high integrity and is a popular technology of choice for the manufacture of centrifuged and mechanical tubes, rings, bearings, rollers, bushings, ball valves, and shaft sleeve or sleeve.  What is centrifugal casting and what are its advantages?

What is centrifugal casting?

The process involves using a centrifugal force (high-speed rotation action) to exert pressure on the molten metal, and it is poured from an external source into a spinning die. The centrifugal force acts to distribute the molten metal in the spinning die at pressures close to 100 times the force of gravity. The mold rotates until the whole casting solidifies. Because of the high G-forces involved in this casting method, the less dense materials, including impurities, are forced to go to the inside diameter periphery of the part, which is subsequently removed by machining, and defects related to gas and porosity are reduced.

According to a report by ResearchAndMarkets, the digital transformation market is expected to grow at a CAGR of 22.7% from 2019 to reach $3,294 billion by 2025. Factors driving the growth in the global digital transformation market are the increasing technological advancements and government initiatives towards digitization.

If we look at our consumption habits over the last 50 years as a global society, it is true that more and more products are being manufactured which consume more and more basic materials. Metals are extracted from minerals after some form of processing and then used in a variety of goods and products. Furthermore, metals are essential for economic development, the functioning of society and the maintenance of our quality of life.

These materials and elements are finite, and we have a responsibility to ensure that future generations will be able to recover the elements after use and reuse them appropriately for other purposes. The fact is that there are many valuable elements that are not always recovered and reused.

The hardness and the strength of a material play a central role when it comes to wear resistance. The principle here is that the harder a material, the more resistant it is to wear. However, with increased hardness, a material also becomes less deformable – its ductility decreases. The result: the material becomes fragile and breaks faster. If the material is too soft, the surface wears out much faster. A material must therefore be hard and still have high ductility. Thanks to years of experience in metallurgy, AMPCO METAL has developed a special manufacturing method that meets these high demands on a material.

Everyone has certainly heard of wear and tear – but what exactly is behind the term? In order to get to the bottom of wear, we have to make a little excursion into physics.

Strictly speaking, wear is mechanical abrasion. This means that whenever two materials collide and rub against each other, mechanical abrasion occurs. This sort of abrasion always results in a loss of weight, because the friction constantly removes material from the surface of an object. A typical example of such a process is braking. Wear is the reason why we have to replace the brake pads on our vehicles from time to time. Due to friction when the brake pedal is pressed, two metals rub against each other and the brake pad loses material – it wears out.

First of all, we need to specify exactly what acid environments are and where they occur. An acidic environment is an area with a pH value below 7.0. The lower the pH value, the more acidic the environment. Such acid environments can be found anywhere in the world – either naturally or caused by humans. In nature, these acidic environments occur mainly at hydrothermal sites in the deep sea or on land, in oil and gas or in sulphate soils. Man-made acid environments include mining areas with their landfills and mine drainage.

Corrosion can lead to cost-intensive damage in your application. The chemical reaction takes place at any time and in any environment. However, certain factors can accelerate the process.

Corrosion is the superficial destruction of a metal caused by its environment. The best-known type of corrosion is probably that of iron, which is known to everyone as rusting. However, iron is not the only metal affected by corrosion and its consequences. All metals are exposed to the chemical process, which manifests itself in very different forms.
