What is Metal Fabrication

Metal fabrication is a process which involves building a variety of equipment ranging from machinery to metallic structures from raw metal. It includes processes like designing, cutting, burning, processing and assembling the final products. Metal fabrication includes designing simple metal sheets to more complex structures used in the building and construction injury. A one stop metal fabrication shop has helped contractors to avoid going to different vendors for a variety of purposes and can help simplify several processes. Metal fabrication includes all of the following

  • Manufacturing cutlery and other metal tools
  • Designing metallic structures used for architectural purposes
  • Manufacturing hardware for industrial and commercial purposes
  • Screw, nuts and bolts manufacturing
  • Stamping and forging

The metal fabrication has a great deal of scope in industrial use. Professional metal fabricators have several options to create a variety of parts and products which can be put to further industrial use. A variety of fabrication processes are carried out on different metals and alloys.

These include all of the following

Cutting the metal

Power scissor are used to cut metals in the fabrication industry and doesn’t require a great deal of manual effort. When it comes to cutting a large amount of material mechanical saws and laser blades are used. Lasers work well on carbon steel because it’s very strong ad durable and requires something extreme to cut through its tough layers.

Removing excess material from the metal

Fabricators can remove material from metals with the help of machining. The material is rotated against a cutting tool. The machine has a number of axes defines the range of motion of the machine.

Punching

Punching involves the use of scissors, pressure is used to create a hole into the metal. This in turn helps to remove the slug and the scrape. The punch helps create cut out shapes of different dimensions and sizes. It punches geometric shapes like a square and circle.

Blanking

Blanking involves removing large portions of metals from different spaces on the metal sheets. Fabricators can blank several pieces in a single setting. Products made through this process are usually used for decoration purposes or for jewellery and making watches.

Stamping and Shearing

Stamping involves raising a bit of metal without blanking it out. Shearing makes use of two different tools which can help shape the metal into a required part.

Bending

Fabricator make use of a break press machine to bend a metal into a certain shape. The machine makes use of two tolls and the metal is placed between these tools. The tools can be operated automatically or manually.

Spinning

Spinning can help shape metal into cylindrical structures. Force is applied to one side of the metal which needs to be rolled. Application include manufacturing of cooking utensils, satellite dishes and musical instruments.

Metals which can be fabricated include steel, carbon steel, aluminium, black iron sheets and stainless steel sheets. If you are interested to learn more about metal fabrication make sure you check out the fabrication processes carried out at Rose Valley Steel Works.

concrete pumping

3 Things You Should Know About Concrete Pumping

In the construction and building jargon, there are multiple terms you may come across. For a layman, there are hundreds of words and phrases which make no sense. Concrete pumping is one of them. You may have heard this phrase but do you know what it means?

To explain it literally would be to say that concrete pumping is a process through which liquid concrete is pumped into an excavation or cavity to fill it up, using a machine. There are two main kinds of concrete pumps. The first one is the one attached to a truck. This uses a robotic arm to deliver the liquid into the required excavation accurately. This arm is also called the “boom”. The pump delivers the liquid concrete wherever required by being controlled by a remote controller.

The second type of concrete pump is the one with a linear arm. This linear arm is then attached to either a truck or a trailer. The attached machine is used to align the arm with the place that requires the liquid.

Now that you know how the concrete pumping works and what types of concrete pumps are there, you can learn more about concrete pumping gold coast from the following tips:

1. Challenges it Faces

Understanding any machine does not come without understanding its challenges. The concrete pumps face a realtime challenge when delivering the liquid concrete from one place to another. Despite the advancement in construction of these pumps, delivering it is a hassle. The concrete liquid is heavy, viscous and contains rocky substances. Because of the liquid’s nature, it becomes hard to easily transfer it using a robotic or linear arm.

Furthermore, the liquid is very heavy and therefore, precision is required to balance the liquid in the mechanical arm for hassle-free delivery.

2. The Liquid Concrete Freezes

Just like cement, the liquid concrete freezes if it is not moved on a regular time period. The liquid needs to be in a constant movement when being delivered into an excavation or a small cavity where it is needed before it freezes.

Interestingly, the liquid can maintain its position if the mechanical arm containing it is in slow, but constant motion to deliver it to the required area. When transferring the liquid concrete, it is important to make the movement slow, yet precise and continuous. Not only will the liquid easily transfer, but not cause any damage to the surface it is falling upon.

3. Mines and Tunnels Use Special Concrete Pumps

Liquid concrete pumps are used as per their needs. Apart from the two main ones mentioned above, there are other concrete pumps too which can be used in smaller sites that are enclosed. These sites include tunnels and mines.

Tunnels and mines use skid mounted and rail mounted concrete pumps as they can carry less amount of required liquid in a small and enclosed area and sustain a constant motion for viscosity of the liquid. Aluminum concrete frameworks within tunnels are usually filled using skid mounted concrete pumps.

What to Know About Hydraulic Hoses

Everything You Need to Know About Hydraulic Hoses

History shows that hydraulic systems have been in use since the early 1940s when a group of engineers came out with a more compact, lighter and even self-lubricating. The use of hydraulic machinery by the military was stirred by World War II. When flexible hydraulic pipes were discovered, it led to the development of other machines that were powered by hydraulic energy.

What is a hydraulic hose anyway? Well. A hydraulic hose is a synthetic rubber, high pressure or thermoplastic pipe that usually carries any fluid (petroleum, synthetic oil, and water) to transmit some force within a hydraulic system/machinery. How is this hose constructed?

This hydraulic hose is made up of 3 main parts namely inner tube, a sheath and spiral wound wire. The inner tube usually carries the transported fluid while the outer protective layer usually protects the hose from adverse weather, oil or chemicals. These pipes are made for various specific mechanical applications. They have specific connectors, sizes, and lengths that enable them to fit into certain specific machines. The following information was provided by: Hydraulic Oils – Hydraulic Hose Fittings – Hydraulics WA

The Lifespan, Types and the Purpose of Hydraulic Hose

You are already aware that nothing in this world is permanent even you. That’s on a light note. However, hydraulic hoses are also not meant to stay forever and it is affected by various conditions. For example;

  • Twisting the hose
  • Kinking
  • Flexing it much
  • Crushing
  • Scratching its surface
  • Stretching the pipe

Also, a major determinant of the life span is the level of temperature. Either too high or too low-temperature increases or decreases the internal pressure of the hose. In addition, avoid using wrong types, sizes or weight of hoses to avoid any breakages. Some of them show some swelling, blisters, bubbles, cracking or even no signs when they are worn out.

The lifespan of a hydraulic hose is also determined by the type of the pipe. Some of the types include:

  • Reinforced rubber hose – its light but cannot withstand high temperatures
  • Steel reinforced Teflon hose– is a strong, light and can withstand high temperatures. They are either return lines or coiled hoses.
  • Corrugated and articulated hose – they are flexible and can accommodate pressure

It is recommended you replace the hose before any sign of failure mostly in heavy hydraulic machinery and brakes of vehicles. Unlike mechanical systems that require gears, chains, and pulleys to move a fluid from the engine, the hydraulic system transmits force through the hose from the force engine.

Fluids in these hoses transmit the force very effectively because of their incompressibility. The force from one end goes to the other end using very little power. When changing the pipe ensure you use the right sizes because they either rise or drop the force in the pipe.

Every hydraulic hose has certain specific ratings depending on the working temperature ranges and the level of pressure. Check the number on the hose before fitting them.

Safety and Maintenance of a Hydraulic Hose

When it comes to the safety of this hydraulic hose, you need correct selection, maintenance, and even replacement. This will decrease the risks when using hydraulic machinery systems. Always have a maintenance routine like on monthly basis and also don’t ignore any leakages especially where there are inflammable sources.

Always replace damaged or any old hose since they are potential hazards, avoid any contamination by cleaning the pipe thoroughly before replacing it. In addition, maintain correct temperature and pressure.

In conclusion, maintain you hose properly despite being the smallest part of a hydraulic system and machinery since it can cause the largest problem and even serious injuries.

Excavator Tracks Maintenance Tips

 

Excavator tracks go through a great deal of wear and tear. It is therefore necessary to provide them with the right kind of maintenance to ensure longevity. In case you don’t get it maintained on a regular basis, it can cost you a great deal of cash in the long run.

If you want the excavator tracks to remain in top condition make sure you practice the following maintenance tips.

excavator tracks

 

Always keep the bottom of the excavator tracks clean and debris free

Whenever the excavator tracks are used, these should be cleaned thoroughly when not in use. Cleaning the tracks would prevent the buildup of dirt and ensure better performance of the tracks every time. He tracks can be cleaned with the help of shovels and high pressure cleaners as well.

The tracks can be prone to a great deal of damage if not cleaned on a regular basis. Too much build up on the tracks can directly affect the fuel usage. Since it becomes difficult to move the tracks due to the buildup, more fuel is used to maneuver the excavator.

 

Make sure to carry out regular inspections

The tracks should be inspected every now and then to check out for any kind of wear and tear. This is also one way of looking for any damaged or missing parts. Those excavator tracks which are used in harsh conditions and on uneven terrain should be inspected more often. Calling a professional would help and they can rule out any damage to prevent complete breakdown of the tracks.

It is necessary to keep track of the track bolts, track chains, the track shoes and to ensure proper track tension.

If any of the parts or components are out of place, the professional can make sure to put it back properly. A loose track pad or a broken track pad should be repaired immediately.

 

Other maintenance tips for excavator tracks

·       In order to reduce wear and tear it is advisable to make wider turns. Making sharp turns or instant pivoting of the vehicle can cause unnecessary tension on the tracks. It can even lead to the de tracking which would mean you would have to call in for professional help.

·       Avoid too much movement on slopes. However, at times it’s not possible to avoid slopes altogether. Therefore it’s necessary that the motor is driven in the correct direction. The drive motor should always face the back of the machine.

·       Avoid driving over extra rough surfaces. These include movement over sharp asphalt surfaces or hard concrete ones.

·       Avoid a great deal of track spinning. It can reduce productivity.

·       Use the right kind of excavator tracks according to your vehicle and requirements. Narrower tracks for hard soils. Wise excavator tracks are useful for softer surfaces because they wont dig into the surface or get stuck.

·       Use the right kind of grouser. The higher the number of grousers the better and easier it is to maneuver the vehicle.

Following these above mentioned tips would help the excavator tracks to work for longer and reduce wear and tear as well.

 

Emissions Control Systems

In the world of automobiles, there are many terms that drivers and car aficionados should know. One of these important terms is emissions control system. What are they and what can they do for your car? In automobiles, the emissions control systems are used to limit the number of noxious gases that come from your engine and the other components in the car. This system can help to keep the air much cleaner along with making your car run smoother and with greater ease.

Gases Emitted From Your Car

When you are driving your car, you may notice that there are quite a few gases that are emitted from your exhaust. These gases can be controlled depending on your emissions system. The gases that come from your car are generally:

  • Carbon monoxide
  • Hydrocarbons
  • Nitrogen
  • Sulfur

You will come to find out that there are many different emission control systems that you can install onto your car to help you lower a number of gases that you are releasing into the air each time that you start your car.

Systems to Help Control Gases

When you are ready to make additions to your car, you will need to be sure to choose the right type of emissions control system. There are a wide variety of these systems that you can install to help keep your engine running better and to help lower the gases being released from your car. One of these systems is called exhaust gas recirculation or EGR. With this system, there are gases that are redirected to the cylinder head in your car. These gases will then be combined with fuel and air and moved back to the combustion chamber in your car. The new gases that are now being produced will help to lower the combustion temperature and better protect the engine in your car.

There are other ways to help your car’s emission become lower. One of the other emission controls systems that you can add to your car is a catalytic converter. This is a type of emissions control system that helps to convert gases and other exhaust fumes into water vapor, nitrogen, and carbon dioxide. Many drivers have noticed some problems with them, but once you start to preheat the catalytic converter, you will see better results almost instantly.

Cost and Repairs For Emissions Control Systems

Like any type of repairs for your car, you may find that repairing your emission control systems seems to be costly. The better you take care of these systems, the fewer repairs and cost you will have to face. However, if you do find that you need repairs, there are some things to keep in mind. Some of the lowest rates for these repairs start at around $100 and go get as high as $399. By taking good car of your car, you will find that these rates are much lower than if you are negligent with your car. Many mechanics know how important it is to get monthly tune-ups on your car, and it is no different when you add these emission control systems.

Taking care of the air quality is just as important as your car. Ensure when you have emission control systems installed on your car, make sure to take great care of them so you will not have any larger problems in the long run.
