Rare Earth Magnets

What Are Rare Earth Magnets?

Rare earth magnets are the pinnacle of the magnetic industry, they are the strongest permanent magnets available on the market today significantly outperforming ferrite and alnico magnets. There are two types of rare earth magnets being used daily due to there outstanding magnetic capabilities. These are neodymium magnets also known as NdFeb and samarium cobalt magnet or SmCo, and although they are both rare earth magnets, they each have very unique magnetic properties.

Samarium Cobalt Rare Earth Magnets

Samarium cobalt rare earth magnets were the strongest magnets available on the market until the introduction of neodymium. This type of magnet is known for being extremely difficult to demagnetise and several other benefits its application can provide. For example, they have very high maximum operating temperature and high resistance to corrosion.

Neodymium Rare Earth Magnets

Neodymium rare earth magnets took the market by storm, taking the title of the strongest permanent magnet available away from SmCo magnets and still retaining it this very day. This type of rare earth magnets differs in properties from the samarium, it is made up of neodymium, iron and boron giving this a lower maximum operating temperature and are susceptible to corrosion if they are not coated or covered.

Rare Earth Magnets in Industry

Throughout the industrial and consumer market rare earth magnets have been progressively increasing in popularity year in year out. Once you understand what rare earth magnets applications and implications you are can understand why they are used so frequently across several industries.

Rare Earth magnets are applied to a situation or job where space is limited as they can be specifically designed and shaped to fit the available space. Rare earth magnets are vital as part of the everyday running of some business’s and their factories as they are the preferred magnet of choice when the greatest possible magnetic pull is required for the task at hand. Therefore, they can be seen across a magnitude of industrial application including a vast variety of industries including:

  • Aerospace industry
  • Renewable energy
  • O.S displays
  • Consumer electronics
  • Food and drink processing
  • Deep-sea exploration




Plastic Extrusion

Plastic ExtrusionNU Gears - Plastic extrusion

The plastic extrusion process is one of the most popular machines today throughout the manufacturing and plastic industry. This is because of the many beneficial factors that come with using the plastic extrusion machinery. The main benefit that comes with plastic extrusion is the low cost and high production rate from the machinery, the ability to manufacture high product volumes quickly and inexpensively makes the plastic extrusion machine an essential piece of equipment in the plastic industry.

Finally, another benefit of plastic extrusion is that the extrusion process is very flexible and versatile. This give the manufacturer the capability to create products of all sizes, shapes, texture and thickness allowing a bespoke plastic extrusion manufacturing process, tailoring products to customers specific needs and requirement if needed.

The 5 steps of Plastic Extrusion

1) To begin the process, you’ll need the right materials. Raw plastic resin is placed and fed down into the extruder hopper along with any colourants and additives necessary for the specific plastic extrusion product you are looking to create.

2) Once the raw resin is in place in the extruder hopper, the resin and beads are gravity-fed through the feed throat of the hopper down into the extruder’s barrel. Within the barrel is a long, spinning screw that feeds the resin forward.

3) The resin travels through the barrel on the screw while being heated to extremely high temperatures. These temperatures can range between 400 to 530 degrees Fahrenheit setting the correct melting temperature specific to that type of plastic. By the time it reaches the end of the screw, the plastic is thoroughly mixed as the barrel gradually increases in heat from the loading end to the feed pipe. This gradual increase enables gradual melting therefore to minimize the possibility of plastic degradation.

4) Next the molten plastic is forced through a screen pack and then fed into a feed pipe that leads to the die. The function of the screen pack is to remove any contaminants or inconsistencies that may have appeared in the plastic

5) Finally, once the molten plastic has entered the feed pipe it is fed into the die cavity, where it cools and hardens.  The die for an individual plastic profile is designed so that the plastic flows smoothly and evenly from the cylindrical profile of the extruder into the final profile shape.

The Plastic extrusion process is one of the most used process’s for manufacturing & producing a wide range of plastic products on the market today. The plastic extrusion process has therefore been adapted and applied throughout many business sectors & industries from building materials, consumer products to industrial parts. Many common items you wouldn’t even realise are made through the plastic extrusion process these include examples such as Pipes, tubing, window frames, electrical covers, fence, edging, and weather stripping along with thousands of custom & bespoke extrusions builds for a specific industrial application.

Gearbox repairs

A gearbox is a device which is used to increase as well as decrease torque (this is a twisting force which causes rotation) through the increase or reduction of speed. Therefore a gearbox is used to change the speed of a moving vehicle. Due to wear over time, gearbox repairs are needed. There are a variety of issues that could go wrong and then need repairing.


Signs that your gearbox needs repairing:

Your gears are slipping

When you are putting your car into gear it should not slip out and if it does, it is obvious that you have a fault. A likely cause of this is that the gears themselves are worn down and will have to be replaced. If you do not repair this, it will only get worst over time.

Gears are noisy whilst in neutral

If you are hearing a lot more noise then you usually do when your car is in neutral, then double check the levels of fluid and try topping it up as it could be low levels of transmission fluid causing this problem.

Burning smell from your car

When it comes to your gearbox, a burning smell can be caused from the transmission fluid overheating. If you ignore the burning smell and do not get a gearbox repair then this could lead for you to have an entire transmission replacement.

Shaking or grinding

A car should never shake, however grinding and shaking is a common symptom of a faulty gearbox when you move from one gear to another. If you ignore this issue, it will only get worse and you will end up acquiring a higher repair cost.

Along with all these signs, there are a variety of other signs that you should look out for as these are only the main factors. These include:

• Leaking fluids

• No response from your gearbox

• Strange noises from the gearbox

• Won’t go into gear

Whether your gearbox needs fixing or replacing, the price will vary from one place to the next but you should get the problem fixed as soon as you can possibly do so to stop yourself incurring a higher gearbox repair cost.
