The performance of magnets such as Neodymium varies across due to the effects caused by various factors. These magnets are widely used for multiple applications, are strong, and have good magnetic properties. More information is available about the Neodymium magnets, and you can click here to read. Generally, all magnets possess a pull rating which is calculated in kilograms. Since there are no perfect conditions for them to work in, their performance is affected differently. We expound on factors affecting magnet performance below.

Factors Affecting the Performance of a Magnet

The factors that affect the performance of any magnet include;

1. Material

Magnets attract metals of different materials hence the effect on their performance. The material they attract determines its magnetism conduction or pull strength. The pull strength is tested using mild steel, which acts as the contact material. Other metals like cast iron or alloys of steel and not used as their power to conduct magnetism is low compared to that of mild steel. They prevent the magnet from reaching its maximum capability. Some metals reduce the pull while others increase it hence the performance effect.

2. The thickness of the steel

A steel surface affects the performance and pull of a magnet. The thickness of the steel must match the magnet’s requirement for it to perform at its maximum and take in all the magnetism. If the contact steel isn’t thick enough, say 1mm, when the required thickness is 10mm, the magnet will not attract as needed and will deliver a fraction of its potential capability.

To test and ensure the steel thickness is okay, attach another piece of steel onto the previous one. If the extra steel piece remains attached to the first one when you move the magnet, the steel cannot fully absorb the magnet’s power. If it falls off, it indicates the steel thickness is correct, and full magnetism absorption is taking place.

3. Temperature

Any magnet used in conditions above its maximum operating temperature range tends to lose its performance completely. The maximum operating temperature varies between magnets. For example, for Neodymium magnets its 80 degrees centigrade, while for Ferrite is 180 degrees centigrade.

If you subject the magnet to very high heat severally, the performance reduces. Magnets have magnetic domains that are aligned; hence they possess magnetic properties. When the domains are misaligned, like in the case of constant heating, they lose their magnetism and can not function as expected. Alternatively, low temperatures are ideal for magnetic performance. When exposed to such, their performance increases.

4. Corrosion

Corrosion mostly takes place in the presence of water. Since most magnets are used outdoors, they are prone to this, causing their performance to decline. The magnet’s plate is damaged, resulting in rust; hence the magnet loses its magnetic power. However, some magnets are designed to withstand such conditions such as Samarium Cobalt.

Conclusion

When buying a magnet, you expect it to have and maintain its original properties during its use; however, sometimes, that’s not the case. The factors above will help you understand what affects it and prevent such exposure to these elements. Take note of them to keep your magnet in its maximum magnetic capability.

What You Need to Know About Plastic Granulators

What is the Purpose of a Plastic Granulator?

Some people might have heard about these machines but can’t tell what they do or how they work. The main objective is to convert any material, in this case, plastic, from its current condition to granulates that facilitate the reusing of the materials. The granulates produced are high-quality due to various reasons.

1. What is a High-Quality Granulate?

You can define this granulate based on three elements: size, cleanliness, or proper sanitation and uniformity.

a. Size

The size of the granulate on the screen brings about balance between the throughput you intend to have and the end product that is the final size of the granulate. The ultimate granulate size is usually compatible with the size of the original material.

b. Proper Sanitation

A high-quality granulate is clean, with no fines or traces of dust. The absence of these elements shows that part of the material was lost during the air conveying process or filtration. Their removal is essential to keep the granulate clean and prevent any adverse effects on the subsequent machines like the moulding and extruder machines.

Also, the choice of material determines whether the granulate will have fines or not. Brittle or weak materials tend to break easily, contributing to fine formation.

c. Uniformity

It’s important to note that plastic granulators cannot be fed materials randomly. The material size must be right. Likewise, keeping the size of the granulate constant allows for a more consistent density and the feeding method.

The uniformity promotes proper mixing and blending of the granulates and the virgin pellets, making the level of melting within the barrel consistent.

2. What are the Tips for Selecting a Plastic Granulator?

There are two main tips to consider that is;

a. Identify Your Application/Purpose

Your application will guide you on the kind of granulator to get. In addition, factor in the size and materials that you will have in the process. The machine sizes vary; hence it is necessary to define the size you want clearly. However, there are chances you can get one that fits all materials, which would be very beneficial to you.

b. Check Out the Machine Parts

Ensure you confirm every part you wish to have is there. Among the essential components is the rotor, which can be opened or staggered. Consider the horsepower, shape and size of the chamber and the number of knives. All these parts contribute to the proper working of the granulator; thus, you can leave them out.

Conclusion

Granulators are detailed equipment with several parts that work together to facilitate the recycling of materials. They appear different based on the involved application, but their main aim is to produce granulates for reprocessing. Consider the tips given for proper selection to get a valuable machine that works for your needs and is worth the money spent.

Printed Circuit Boards have grown in popularity over recent years. They support electrical and electronic devices in daily home use or other applications like Medicine where the medical PCB is used. Manufacturers produce various forms of PCBs based on factors like materials, design, and how they are used. As for the material, it’s essential to know and understand how each one behaves, their advantages and limitations, and the type of PCB they can be used on. We discuss the materials used in PCB manufacturing below.

Materials Used in PCB Manufacturing

PCBs can either be rigid or flexible, depending on the choice of material. Every PCB has an insulating layer that is a poor conductor of electricity and is known as a dielectric material or substrate. Some examples include glass epoxy laminates, plastics, porcelain, and few metal oxides. The substrate is used alongside conductive metals like copper to allow current flow. Other materials include;

1. FR4

It is the most common type of material used in PCB. It is an epoxy laminate sheet reinforced with glass and has good tensile strength. Since it’s a composite material, its purpose is to offer mechanical support for all components on the board. Most people prefer it due to its ability to resist water, meaning it doesn’t get damaged if the electronic device gets in the water.

FR4 comes in three forms, i.e., standard, halogen-free, and high glass transition temperature. The standard kind is the most widely used and is the cheapest. The halogen-free and the type with a high glass transitional temperature work well with the lead reflow technology.

2. FR 1 and 2

These materials are suitable for use in the single-layer PCB and are made from phenol and paper elements. They have the same qualities, but the difference comes in the different temperature ranges during the glass transition. The transition glass temperature for FR1 is higher than that of FR2. Like FR4, the materials come in the same forms, i.e., the standard and halogen-free but have a new kind that is non-hydrophobic.

3. Polyimide

It is used to produce flexible PCBs and is made from Rogers, Kepton, and Dupont components, which are the reasons behind its excellent electrical properties. Its good at resisting chemicals, and its range of temperature is more comprehensive compared to other materials.

4. Prepeg

The material name means pre-impregnated, and it is not as popular as other material names used in PCB manufacturing. It refers to fiberglass materials filled or impregnated with resin. The dried resin is melted, allowing it to flow and immerse in the fiberglass. Prepeg is naturally sticky, and its adhesive layer provides good tensile and mechanical strength. This material’s resin content creates many versions, such as standard, medium, and high resin. The three types are also determined by structuring the layers, their thickness, and electric resistance.

Bottom Line

As listed above, several materials are available, and picking the right one, especially during the design process, is vital. Some of their qualities are similar while others are different, thus contributing to their use in various applications.

If you are in manufacturing, you know just how important it is to have all the valves well sealed. Leaking fluid and gases can be dangerous to the factory and can cause huge accidents. It is for this reason that people get PTFE gaskets and sheetsfor their pipes around the factory. You can get your Multidirectional Expanded PTFE Sheet China Manufacturer, who are known to have genuine products. Here are some of the main perks of PTFE gaskets.

1. Highly resistant to chemicals

One of the biggest perks of using PTFE gaskets is that it is highly resistant to the chemical. It is the main reason it can seal up pipes that deal with aggressive chemicals like acids, bases, and solvents. Tests done with the gaskets show that they do not let any liquid pass through, no matter how strong it is. They can be trusted to hold everything in when it comes to closing up such valves.

2. Resistant to high temperature

Another perk of using PTFE gaskets is they can withstand high temperatures without melting or disintegrating. The quality makes it appropriate for food manufacturing and packaging companies since most of them have to heat the food and cook it fully before they package it. Getting gaskets that can withstand the right temperature and lower temperature for foods sold frozen is a great perk because the companies do not have to worry about cross-contamination from the gaskets.

3. Versatile

One of the main reasons many companies use PTFE gaskets is the versatility it comes with. The gaskets come in a variety of thicknesses, filters, and compression sheets. You get to choose which one will suit you and your needs. The various sizes mean you can use them for different uses. Most companies allow you also to get your custom-made size to suit your needs.

4. Works well as an insulator

Whether you are working with electricity or heat, getting gaskets that insulate against them can be a great plus for you. With PTFE gaskets, you get all these features. They work very well as electrical and thermal insulators, which means you can use them for insulation purposes. It can be used even in a heavy-duty industry that needs insulation, although they might have to make it thicker to withstand all the work it will be doing.

5. Easily available

Getting PTFE gaskets is very simple, all you need to do is get the right manufacturer and place an order for them, and you will get it in no time. It beats the hassle of figuring out where you will get the gasket from or having to buy them at a very high price. Many of the factories that manufacture PTFE do it at an affordable price that even a startup can afford.

Conclusion

Running a manufacturing plant means that you need to know the different components of the plant itself. PTFE gaskets might not be a big part of the plant, but they play a major role in ensuring the machines are safe and working. Getting the right PTFE gaskets is very vital to the running of your plant.
