5 Key Advantages of Custom Metal Fabrication

What does an assembly line make you think of? If you answered “sameness”, you wouldn’t be alone. Repetition, huge orders, a factory producing one product.

Hey, there’s nothing wrong with assembly lines. They’re helpful and efficient. But the one thing they don’t do is a custom job.

When it comes to metal parts, custom is the way to go. Here are the 5 advantages of custom metal fabrication:

1) You Choose What You Want

Not all parts will work for all jobs, and all metal parts can’t be bought in a store. With custom metal fabrication both problems solve themselves.

On top of getting the ability to choose exactly what the part is going to look like and what it’s going to be made out of, you’re also given the opportunity to save time.

In deciding how you want a part, you’re also making the decision how that part gets made.

2) Get Your Job Done More Quickly

Will it be a cut-and-roller job, or will it be a cast-and-form job? This factors into how quickly you’ll get your part. For all you know they’re out of your part at the store.

For all you know they’re out of your part at the store, and by the time they’re able to order a new one you could have had one that would haven’t just been a better fit for your project, it would have quite literally been the perfect fit.

3) Custom Metal Fabrication Means Handy Metal

Though some companies have the ability to work with other metals like aluminum, cast iron, and manganese steel, plate or sheet metal is most commonly in custom metal fabrication. This durable metal means several convenient things.

Sheet metal is lightweight. That means the product you get fabricated will be light as well. That will cut weigh down on transportation costs.

4) There’s Strength in Custom Jobs

Additionally, sheet metal doesn’t wear down easily and will look the way you want it to, or act the way it needs for a good long while. This has both aesthetic and practical implications.

Though it’s strong and light, perhaps the reason it gets used so often is its durability. It withstands heat and corrosion, meaning the thing that you built is built to last.

5) It Requires Its Laborers to Have Skills

This is no ordinary job! Much the same way your set of skills has landed you where you are, it takes a group of highly-skilled laborers to pull off custom metal making, which means you’ll work with the best.

It comes highly recommended that you find one company to work with for the majority of your transactions so that you can build up trust. The custom fabricated metal industry is a highly specialized industry.

This means, find someone you’re ready to spend a career partnered with.

Perhaps among the most important things to do is to find a company today that has the capabilities of taking on odd, often last-minute requests.

You’d be surprised (or maybe you already know…) just how often this kind of thing occurs.

US Manufacturing Industry Report: 5 Big Trends to Watch

US Manufacturing Industry Report: 5 Big Trends to Watch

2017 has been an exciting year for the manufacturing industry. The industry has seen some major breakthroughs and taken some surprising turns.

The US manufacturing industry now stands to be one of the major influencing forces of the year on the US economy and workforce.

5 Things You Should Know About the US Manufacturing Industry

We’ve combed the latest headlines to come up with the top 5 trends and statistics that are taking the US manufacturing industry by storm.

1. Manufacturing Employment is at a Steady Low

Manufacturing jobs in the US are currently at 12.4 million. While this number reflects an increase since 2010, when it was only 11.5 million, it shows a sharp decline since peaking in 1979 when there were 19.4 million workers in the industry. Today, the overall industry remains at its lowest since before WWII.

2. South and Midwest Regions Have Been Hit Hardest by Decline in Jobs

Areas that have traditionally relied on manufacturing in the south and midwest have been hit the hardest by the loss of jobs available. The obvious effects that the decline has had on workers may lend to the fact that four out of five Americans, are aware that jobs in the industry are down, according to Pew Research Center.

3. Jobs May Be Down, But Productivity is Up

Most Americans may realize that jobs are down, but what most don’t know is that output has grown. Pew Research Center’s report claims that while 81% of Americans realize that manufacturing employment has decreased, only 35% know that productivity has increased.

The gains have varied widely across manufacturing industry categories.

The report shows that there has been a whopping 2,600% increase in productivity in computer and electronics since 1987. However, in motor vehicles and parts, the percentage has ebbed and flowed, dropping during the recession, but now showing a 124% lead over its level of output in 1987. And, the textile sector has seen an overall decrease in productivity since 1987 of over 50%.

4. Advances in Automation Lend to Productivity Increase

How can one of the industries with the biggest losses in jobs account for its thriving rate of production? The answer, at least to a major degree, lies in the growth of automation.

Few industries aren’t at risk for being affected by the reliance on automation. Among them, first line supervisors of mechanics, installers, and repairers.

5. New Research Indicates 1 in 4 Jobs at Risk for Being Off-Shored

In addition to automation, off shoring has created yet another option for less expensive labor costs. In an effort to cut spending, many companies will turn to off shoring to meet their production needs.

25% of Americans are at risk of losing their positions to offshoring.

This may be a good deal for the companies, but it comes as a cut to the national workforce, whose manufacturing jobs have already suffered major losses.

Conclusion

If you are in the manufacturing industry, you need to know the latest stats and information. The manufacturing industry is changing in a major way. Make sure that you stay on top of the information that you need to know!

5 Telltale Signs Your Rope Drum Needs Maintenance

Not only can changing out rope drums be time-consuming, but it can also be difficult to tell when the right time is to have your rope drum serviced.

Not to worry. Below are the five telltale signs your rope drum needs maintenance.

1. Wearing Down of the Grooves

A study conducted in connection with the steel industry showed that the number one reason for changing out rope drums was that the grooves were worn.

Having worn grooves can be dangerous, which is why it is important to keep maintenance a top priority. There is a risk that it could pinch or damage the rope. It could even potentially cut the wire rope.

The best way to avoid these issues is to pay attention to both the material of your rope drums and the heat treatment.

2. Rope Looks Worn or Damaged

Another major sign that your rope drum needs maintenance is that the rope itself is worn or frayed.

Small particles can be abrasive to the rope, causing wear and tear that weakens the rope. If anything gets caught in the rope, that can cause damage too.

A weak rope means a weak rope drum. Ensuring that the rope is in good condition will greatly prolong the life of your rope drum. This is an important step in every rope drum maintenance effort.

Cleaning your rope from time to time can help combat this wearing down of the rope. Taking preventative measures like these is an important part of extending the life of your rope drum.

3. Rope Is Loose

It may be time to do some maintenance on your rope drum if the rope has come loose at all. If the rope is loose or out of place on the rope drum, the rope drum will not function properly and will need to replaced much more quickly.

Ensuring that the rope is properly in place on your rope drum will help it continue to function properly. If this is not the case, it is time to do some maintenance on your rope drum.

4. Groove Surface Is Crushed

Another issue that may come about with your rope drum is that the drum surface becomes crushed, leaving it flat and smooth. There should be grooves holding the rope in place on your rope drum. If these become worn down or even crushed, your rope drum will not work properly.

Check the groove surface regularly to ensure that your rope drum is still in good working condition. If it’s not, chances are it’s high time for maintenance.

5. You Don’t Have A Rope Drum From A Kor-Pak Supplier

Kor-Pak offers a full range of rope drum material and heat treatments. Our TSP-carburized rope drums virtually eliminate the need for maintenance. They also significantly improve the performance of your wire rope.

Kor-Pak carries rope drums that are carburized and hardened to 60-65 Rockwell C. They virtually eliminate the crushing and corrugation of the rope groove surface, which greatly helps to extend the life of your wire rope and your rope drum overall.

Contact us today if you have additional questions about rope drums.

Stainless Steel Fabrication: How Is It Made?

Stainless Steel Fabrication: How Is It Made?

Stainless steel is well known for its ubiquitous practical uses — making appearances in a range of commercial and industrial applications.

Since stainless steel contains chromium, it’s highly resistant to rust and corrosion.

Its ability to withstand high temperatures, high pressure and still be ductile and malleable makes it ideal for a wide range of oxidation resistant applications.

Stainless steels, by nature, are alloys of iron with a chromium content of at least 10.5 percent.

Other alloying elements in stainless steel include copper, titanium, nickel, molybdenum, nitrogen, and carbon. These elements are added to enhance its properties such as toughness and formability.

Due to its versatility, there is a wide range of stainless steel fabrication techniques.

The Importance of Chromium in Stainless Steel Fabrication

Chromium is a hard, corrosion resistant element that gives stainless steel its corrosion resistant properties. It’s an essential element in the manufacture of stainless steel and has no viable alternative.

In the presence of oxidizing agents, the stainless steel forms a passive film (chromium oxide) invisible to the naked eye on the surface.

As the film adheres strongly to the surface of the steel, it protects it from interacting with the environment, stopping the electrochemical reactions that cause corrosion.

How Stainless Steel is Made

The Manufacture of Stainless Steel Involves a Series of Processes.

1. Melting and Casting

The alloy materials are melted in an electric furnace for around 8 to 12 hours until the metals become molten.

The molten mixture is then decarburized in an Argon-Oxygen Decabuliser (AOD) to remove excess carbon. This involves blowing argon, oxygen, and nitrogen into the molten steel.

At this stage, other alloying elements such as nickel and molybdenum can be added enhance the properties of the stainless steel.

2. Tuning and Forming

Tuning involves stirring the steel slowly to remove unwanted elements and maintain the right chemical composition.

After tuning is complete, the molten steel is cast into forms. This is done by passing the refined stainless steel through a casting machine to form slabs, billets (round or square shapes), blooms (rectangular shapes) and tubes.

3. Hot Rolling

Hot rolling involves heat treatment of the final products after the forming process. It involves heating the slabs to between 1,100 to 1300 degrees Celsius, depending on the type of steel.

Through the heating, billets and blooms are further formed into bar and wire while slabs are formed into strips, sheets, and plates.

The plate thickness can range from 3mm to 60mm.

4. Cold Rolling

Cold rolling involves subjecting the rolls to a relatively low temperature. The process not only reduces the thickness of the rolls but also produces smooth, shiny finished, and cold rolled stainless steel.

5. Annealing and Pickling

Annealing is the process used to soften the stainless steel and improve its ductility. The annealing process results in a scale build up on the steel, which is often cleaned through a process called pickling.

Pickling involves bathing the steel in nitric hydrofluoric acid. Alternatively, the scale can be removed through electrocleaning — a process that involves the use of electric current to get rid of the scale.

6. Cutting

Cutting operations are necessary to give the final product the desired shape or size.

Mechanical cutting involves the use of guillotine knives for straight shearing, circular knives for circle shearing, or steel blades. Other methods of cutting include nibbling and blanking.

7. Finishing

In applications where the appearance of the stainless steel is important, applying a surface finish can give the steel an attractive look.

Some surface finishes also make the stainless steel easier to clean, which is important for kitchen appliances.

Surface finishes are in most cases the product of the stainless steel fabrication process. For example, annealing, hot scaling, and descaling result in a dull finish.

A combination of annealing and cold rolling in controlled temperatures produces a reflective finish. Abrasive belts and grinding wheels can also be used to polish steel.

To Sum Up

Currently, there are over 60 grades of stainless steel, all categorized by the alloy elements of their microstructure. Within these grades are the three most popular types of stainless steel, namely, austenitic, ferritic, and duplex.

Each type of stainless steel differs depending on the percentage of chromium and the proportion of other elements.

How Electric Brakes Work

How Electric Brakes Work

Electric brakes are standard features on trailers, and they’re similar to the hydraulic brakes on cars. The only difference is that electric options use electromagnets while hydraulic pressure powers car brakes.

An electric braking system has several components, including a magnet, shaft, actuating arm, small front shoe, reactor spring, and larger rear shoe. All these parts work together seamlessly to support the overall function.

If you’re curious about the workings of an electric break, this post is going to help you to learn that.

Read on to learn more.

The Controller

An electric braking system requires the use of brake controller, which is usually connected to the battery and stop light switch. This component regulates the electric current sent to the brake once your press the pedal.

Your trailer can have the time delay or proportional brake controller. These are the two common types of controller. Proportional controllers work by determining how the tow vehicle is stopping and regulates the power to the brake proportionally.

Proportional controllers work by determining how the tow vehicle is stopping and controls the power to the brake proportionally. The use of this controller allows the trailer brakes to be applied at the same time and rate as the tow vehicle brake.

With a time delay controller, you have to adjust its controls to suit your trailer weight and the moment when you apply the trailer brake. This is important to avoid too little or too much stopping resistance when braking.

The Braking System

As you already know, electric brakes have a magnet, which is usually on the backing plate. The plate is usually bolted to a flange on the trailer axle, which is the passage of the hub and the bearings. This magnet has two conductor wires that are directly connected to the trailer spring.

So, when electric power is on, it activates the magnet, which is then attracted to the drum face. The contact of the magnet and the drum face results in friction that prompts a rotating action. This rotation causes the actuating arm to pivot, pushing the brakes shoes out against the inside of the drum.

When this happens, the hub stops, resulting in the stopping of the wheels.

Safety Features

Federal laws in most states require the use of a safety circuit for trailers that have electric brakes. This circuit is known as a breakaway system, which is designed to apply the brakes if the trailer disconnects from the tow vehicle.

The breakaway system features a battery and switch. The switch has a non-conductive plastic that separates its contacts. A lanyard connects the plastic to the tow vehicle. So, if the trailer disconnects from the trailer, the lanyard pulls the plastic, allowing the switch to close. This stops the brakes of the trailer.

Electric Brakes – The Bottom Line

Understanding how electric braking systems work is essential to ensure safety when using your trailer. Different states have varied laws regarding the ideal towing practices.
Ideally, it’s safe to have electric brakes if you have a camper or an RV. Make sure to get braking system that suits your particular vehicle for the best performance.
