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.

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.

For instance, magnesium oxide or talc is sometimes added to reduce setting time and avoid cracking.

What are Machined Castings?

Everything You Need to Know About Plaster Casting

What is it Made of?

You’d think this was a simple answer – plaster, right? It gets a little more complicated. Machined castings are made in different ways. The plaster pattern is made of either metal or rubber. Next, it is often coated with an anti-adhesive material to avoid it sticking to the mold.

Molds are Inexpensive

Machined castings can get expensive and large. With plaster castings, it’s easy to change, reuse, and remold. They are also pretty affordable. If you want to get a machined castings quality product without gaps around the mold, and at an affordable price, plaster casting is the perfect option.

Plaster Casting Process

Machined castings require a lot of attention to detail to get the result you want. Once you have determined the parting line, or where the two halves of the cast meet, the plaster is combined and the pattern is covered with an anti-adhesive. The plaster is then poured into the pattern and shaken, allowing the plaster to fill the gap. Finally, it is left alone in the cast for about 15 minutes to set.

Once you feel comfortable with the mold, it is heated at high temperatures to remove all the excess water. As soon as the metal hardens, the plaster is removed from the cast and the finishing process begins.

Guide in Choosing a Forging Manufacturer or Supplier

Know Which Type You Want

Forgings have two most popular forms. These are open die forging and closed die forging. Although both originated in the fundamental forging process that involves beating a piece of metal until the desired shape, strength, and granular level is achieved, these two processes have differences.

Choosing a Company That Delivers On-Time

Did you know that your success as a company depends on the complex relationships that make up your supply chain? Be sure that your supplier supports your success and delivers on-time, all the time. A delay in the delivery will make things complicated and may even compromise your production.

Fact Check of the Company’s History and Reputation

Sellers and manufacturers aren’t hard to find. Some companies focus on low-cost and low-quality solutions. Hence, you can immediately spot them as their products fail to stand the test of time. 

Thus, it’s essential to look for a reputable supplier with a proven history of producing forgings that offer high quality and durability. Your reputation in the industry is at stake if you fail to choose companies that provide quality forgings.

Look for Any Certification

The supplier or manufacturer you chose to provide you with forgings must adhere to industry standards and specifications. In this way, produce durable and resilient forgings that can withstand extreme temperature, pressure, or adverse weather conditions.  

Certified suppliers and manufacturers maintain data-driven systems that are continuously audited. Aside from the fact that they quickly address quality issues by creating quality improvement plans, they also conduct subsequent reviews to monitor and evaluate these plans’ effectiveness.

How Accurate is Investment Casting?

Investment casting is one of the first and most common types of metal components. The procedure to create these components involves pouring molten metal into a ceramic mold. The metal solidifies within the mold, and then the metal casting is broken out. Industries that focus on food equipment, railroad, heat treating, steel production and processing, coal mining, road construction, oil, aerospace, aircraft, and other countless industries discovered the benefits of this type of casting.

where is the best investment casting?

Accuracy of Investment Casting

Near Net Shape

Investment casting is extremely accurate and near net shape. Since metal components are created by using the same wax pattern, this accuracy can be maintained from casting to casting. Additionally, this process uses stainless steel, aluminum alloy, titanium alloy, or superalloy to create and yield precise metal components that can withstand high and low temperatures.

Additionally, near net shape manufacturing is an ideal solution for those wanting to save money as much as possible. This is because near-net-shape manufacturing does not require finishing steps. So, when you do not need any time for machining done, you can save on production costs.

Intricate Design

When using investment casting, engineers can design and create a lot to customize your product. Logos, product ID’s or numbers, letters, thru-holes, slots, blind holes, external and internal splines, gears, and thread profiles are just some of the intricacies that can be done.

Guarantees Product Quality

To ensure product quality, investment casting uses different methods such as coordinate measuring, ultrasonic, and dye penetrant. These methods will be used according to where the metal components will be used. Dye penetrant testing is a nondestructive method, and it includes cleaning the surface of a product, then applying a colored penetrant, or dye.

Ultrasonic testing is also nondestructive testing that works by sending high-frequency wavelengths through an object to detect cracks and other possible flaws. Lastly, coordinate measuring uses a probing system in the machine, and data collection allows for precision, which results in durability.

Comparing Die Casting and Investment Casting Methods

Die casting, and investment casting are 2 of the foremost important types of casting. Die casting is a method wherein molten metal is created and formed into a mold cavity by way of enforcing high pressure. On the other side, investment casting is a process that involves the injection of wax into the aluminum cavity. Both die casting and investment castings have different advantages and disadvantages. Read on to know more.

where are the best investment castings?

How Does Die Casting Differ from Investment Casting?

Die Casting

As stated earlier, die casting differ from investment castings in such a way that the former involves a metal casting procedure. It is categorized by the use of a mold cavity to apply high pressure to the molten metal. These molds are then machined, designed, and created from higher strength alloys. Additionally, the majority of die castings are iron-free.

Among the notable advantages that clients opt to choose to die castings over investment castings are the following: it has an exceptional economic effect, high productivity, and creates good product quality.

Investment Castings

Investment castings involve an exact and strict casting process through the use of the lost-wax process to create components in the metal cast alloys. This process is known to be very accurate, creating components with accurate dimensions and smooth surface finishes. With this process, the machining and finishing processes are reduced. Thus, it will be more cost-effective without even compromising the quality. The only downside when choosing investment casting is that it is more expensive than sand casting.

Other Differences

Casting predominantly includes special casting and sand casting. Investment casting is included under special casting while die casting is considered pressure casting, which is another major type with the same level as investment castings. As for the cost, die casting costs are higher than investment casting since the former involves post-processing operations and high-processing costs. However, when large production is needed, die casting is recommended because investment casting is a manual process that requires more time and cost.

Heat Treating Baskets | The 3 Different Heat Treatment Processes

For hundreds of years, people have been heat-treating metals for the purpose of improving their physical and chemical properties to fit a given application. However, we’ve come a long way since the blacksmiths of the middle ages forged and tempered metals to produce tools for everyday life. Today, material engineers and metallurgists use more specialized techniques and tools such as Heat-Treating Baskets to customize materials for definite applications.

 

The 3 Major Heat Treatment Processes

 

  1. Hardening

 

This process involves the heating of steel at a specific temperature until its pearlite is transformed into austenite before it is rapidly quenched in water or oil. The appropriate temperature at which the transformation quickly takes place is highly dependent upon the steel’s carbon content. For the core to be fully transformed into austenite, the heating time must be increased. In case you’re wondering, the hardened steel part’s microstructure us martensite, ferrite, or cementite.

 

  1. Tempering

 

When steel that has both been quenched and hardened for a period of time prior to being heated, the process involved would be tempering. The temperature at which this process is carried out is a critical factor that dictates the hardness and strength that is obtained. For example, high temperatures will produce high ductility, but low in hardness and strength. Conversely, low temperatures will result in low ductility, but high in hardness and strength. It’s extremely important to select the appropriate tempering temperature to achieve the desired level of hardness and strength. Tempering is performed on carbon steels that have been hardened to reduce their brittleness.

 

  1. Annealing

 

When steel is treated up to high temperature then cooled very slowly to room temperature to produce its high ductility and strength, but low in hardness, the process of annealing is being applied. In other words, annealing is performed by heating a component to the appropriate temperature before it soaks it at room temperature. The furnace is then shut off while the piece of steel is inside it.
