What You Need to Know About Shock Resistance Testing

Simulate Real-World Use

Although shock resistance testing is sometimes compared to vibration testing, the former involves a more complicated and extreme process. The procedures are designed to use a specific type of force to recreate real-world use. Producers and manufacturers use an accelerometer to gauge the force and speed. Through this, the materials will be exposed to loads of pressure and impact.

After which, they assess and classify the material for stress and damage. Because of these rigid procedures, manufacturers and producers are able to guarantee that the product can meet the demands of its work setting.

Accurate Results

A team of experts conducts shock resistance testing that complies with several military and industrial standards such as EN 60068, DEF STAN 00-35, MIL-STD-810, and RTCA DO-160. These engineer experts aim to support custom and complicated projects through the assistance of specification selection and protocol development processes. Since manufacturers and producers possess a global platform of experts and laboratories, getting accurate results on time is never an issue.

Other Tests

Aside from the shock resistance test, there are also other tests that manufacturers routinely perform to guarantee quality results. Some of the tests employed are impact testing, drop testing, shock and impulse testing, bump/shock testing, decaying sine wave testing, shock pulse testing, and operational crash safety.

The History of Forging

Ever wondered how open die and closed die forging began? The art of forging emerged around 4,000 B.C. – some even say that it began way before this time. Metals like iron and bronze were forged to produce hand tools and other weapons for defense. However, the earliest recorded metal forged by early generations was made out of gold. If you want to know more about the history of forging, please read on.

Centuries of Forging Developments

Before the 19th Century

Limited amounts of natural gold were found in Spanish caves and were said to be used as tools and weapons in the late Paleolithic period. The forging of steel and iron continued in the 19th century and its improvements became the pillars of what has become of today’s forging processes.

19th Century

Forgers and other experts on the forging process were specifically skilled at hand, especially when it comes to open die and closed die forgings. Since bent and twisted iron can only be produced in high heat, the forgers became dexterous in hammer welding and several large shaft forgings.

In 1856, the emergence of the Bessemer steel-making process became a breakthrough in the history of the forging process. People now have an abundant supply of low-cost steel for creating and designing large quantities of forgings.

Historians say that the first cavity steel forging began with the help of the closed die process. It commenced in the United Stated in 1862.

20th Century

The Industrial Revolution and World War II both lead to the development of better forging equipment and processes. Eventually, electrical motors and induction heaters enabled forged rolled rings to be produced quicker, easier, and more effectively than ever before.

Continuous and Lost Foam Casting

There are several types of machined castings and the less discussed methods are continuous

and lost foam casting. Both have complicated technological processes and complex technical characteristics. Here are the facts on the two types of castings.

where can i get machined castings?

Why Choose These Types of Castings

Continuous Casting

It is a state-of-the-art casting method that involves the continuous pour of molten metal into a crystallizer. Once it solidifies, the casting is continuously pulled out from another end so the metal can obtain any specific length.

When it comes to technical characteristics, continuous casting can enhance production efficiency. Likewise, because of the simplified techniques, this process can dramatically reduce the desired production area and labor intensity. Another advantage why using continuous casting is recommendable is the fact that it offers good mechanical properties, uniform structure, and dense crystals.

Continuous castings are often applied in productions with cross-sectional shapes like pipes, rod billets, slabs, and ingots. This type of casting is also used in components made of magnesium alloys, aluminum alloys, copper alloys, iron, and cast steel.

Lost Foam Casting

Otherwise known as a solid casting, lost foam casting is a contemporary method that involves a combination of foam or paraffin models akin to the shape and size of the casting to produce a model cluster. After drying and brushing the refractory coating, it is buried in dry sand and poured under intense pressure to vaporize the model.

As for its technical characteristics, lost foam casting can reduce production costs and investment. It also offers a high degree of freedom during the production process, flexible design, and no parting surface.

As for application purposes, it works best in producing different sizes of precision castings with complicated structures. The best thing about this type of casting is that there are no restrictions on the kind of alloy used.

Forgeability of a Metal

The ability of a metal to undergo deformation without cracking by means of forging is what experts call the forgeability of a metal. With this characteristic, metals can easily be formed with low force and resistance. For instance, closed die forging involves a process wherein the dies move toward each other by covering the metal. The heated raw material is placed at the bottom die to produce a design or shape according to specifications. To know more about the forgeability of the metal, please continue reading.

 

What is Closed Die Forging?

All about Forgeability

Tests to Determine Forgeability

According to experts, there are two primary tests to determine forgeability of a metal – Upsetting test and Hot-twist test. Upsetting test involves cracking while upsetting a cylindrical specimen.  Although this test only provides basic guidelines, it uses different strain and temperature rates to ensure that forgeability can be determined.

On the other hand, the hot-twist test requires the twisting of a metal rod at different temperature rates. Using this method, forgeability can be determined for various materials, including steel.

Extrusion Process

Extrusion is conducted by deforming metal and transporting it into a chamber before the compression process starts. In standard extrusion procedures, a round billet is placed in a chamber and forced through a die opening by a ram. Additionally, this process requires extreme temperature for the material to be completely formed.

The methods of extrusion involved in forgeability of a metal are direct extrusion, indirect extrusion, hydrostatic extrusion, and impact extrusion.

Metal Flow

Metal flow is an important factor to consider when deforming a metal. It must have a substantial reduction in the cross-sectional part of the process to make sure that the flow is undisturbed. Also, extrusion defects may occur if there are impurities and oxides caused due to the inhomogeneous flow of metal. When this happens, surface defects will thrust or be expelled into the center of the extruded parts.

How were Investment Castings Used in the Past?

Investment casting, otherwise known as a lost wax casting, is one of the oldest metal-forming processes that is still used as of this date. Approximately 5,000 years ago, investment castings started with a basic beeswax-formed pattern. Today, it involves highly complicated processes and technologies using refractory materials and specialized alloys.

what should i know about investment castings?

The History of Investment Castings

Original Use

The use of investment castings in ancient civilization was a bit different from the current method applied today. In the olden times, the craftsman designed the casting from beeswax by using basic tools such as shaving tools, melted wax, and other hot tools. To create the desired form, the craftsman will forge a pattern on the wax shape.

They will then fill the mold with a thin layer of melted wax. As soon as the wax mold is coated in ceramic, a perfect mold of the wax shape can be created. It will then be left to dry out before the craftsman can use it to forge a metal object. Such a process is generally used to create jewelry, decorative objects, and religious objects.

Modern Use

Investment casting is a complex metal-forming development that allows metal workers to create products with intricate and remarkable surfaces. The process starts by creating a mold and producing accurate patterns through the latest technological advancements. The good thing about the modern application of investment castings is that when the workers use wax to make patterns, it can still be reused.

The flexible patterns allow for easy reproduction and stress-free production of wax materials that underwent a series of coating and hardening. Once the materials are invested – jargon for poured – into the mold decorated with unique patterns, it will go through a lot of processes such as dewaxing, heating, pouring, removal, and cleaning.

Inconel | What You Need to Know About Inconel

In today’s manufacturing industry, the use of metal alloys is as prevalent as ever. The whole metals of old have been replaced with metal “blends”. An example of this is Inconel. Let’s take a look at what you need to know about this type of alloy and where you can find it for your next project.

What is It?

Inconel is a name for certain groups of nickel alloys, many of which also include chromium. It is one of the most popular types of alloys in modern manufacturing. This is due to its resistance to rust and corrosion, as well as its hardness and durability.

What Are Its Uses?

Inconel is commonly used in parts destined for high-pressure environments. Examples of this include turbine blades, exhaust pipes, and heat shields. It is also used in various types of automotive and aircraft parts that have to stand up to high pressure and/or high temperatures. The heat resistance is what makes it so popular. Where aluminum or even steel might wither and not handle heat well, Inconel reacts very well to high temperatures.

Is It Easy to Work with?

One of the few drawbacks to the durability is that it can be difficult to work with when it comes to production equipment. Since it handles high temperatures so well, things like machining and welding can be a challenge. As a result, a water-jet cutter, or specific kinds of ceramic cutter is needed when dealing with it.

Steel Castings | Types of Cast Steel

Steel castings are solid metal objects produced by filling the void within a mold with liquid steel. While cast steel typically has lower mechanical properties than other metals with the same chemical composition, they are better because they can be made into complex shapes in few steps. Let’s take a look at a few of the different types of cast steel

Carbon Cast Steel

Like other types of steel, carbon cast steel is classified according to its carbon content. Low carbon cast steel is relatively soft and not readily heat-treatable, while medium carbon cast steel is somewhat harder and can be strengthened by heat treatment. As you can imagine, high carbon cast steel is used when maximum hardness and wear resistance are desired.

Alloyed Cast Steel

Alloyed cast steel is categorized as either low- or high-alloy. Low-alloy cast steel reacts similarly to that of normal carbon steel. However, low alloy carbon steel has higher hardenability. High-alloy cast steel is designed to produce a specific property, such as corrosion resistance, heat resistance, or wear resistance. Some common examples of high-alloy steel include stainless steel and Hadfield’s manganese steel.
