Durability: Why Metal is Still the Best Material for Medical Device Manufacture

Posted by on 7:15 am in Uncategorized | Comments Off on Durability: Why Metal is Still the Best Material for Medical Device Manufacture

Plastic is often heralded as the way forward for medical devices, but it’s not without its drawbacks. Metal is still growing and improving as a medical material, and should not be discounted in favour of the plastic hype. Metal is highly durable, making it the ideal choice for many medical devices for multiple reasons. Here are just 3 reasons why you should still consider durable metal fabrication when getting your next medical device manufactured.  Durability Makes Metal Safer While it is true that high performance plastics can be durable, metal is still the stronger choice. The alloys used in medical manufacture are able to withstand very high amounts of pressure, heat and repeated impact, while brittle plastics are more prone to breakage and deformation. Take, for example, two materials used to make hip prostheses. Lennite UHMWP, a thermoplastic, has a yield strength of just 22.9 MPa (meaning it can take 3,320 pounds of force per square inch). Titanium alloy TIMETAL 367, on the other hand, has a yield strength of 800 MPa (116,000 pounds of force per square inch). Metal alloys also have added benefits like corrosion resistance, and the ability to be manufactured in more precise sizes than plastic. These factors are incredibly important for devices that will need to penetrate bone, come into contact with corrosive substances, or remain in the body for long periods and withstand constant strain. If a device breaks, bends or corrodes while in contact with the patient’s body, the results could be catastrophic. Resistant metals are a far safer choice for medical devices that could threaten a patient’s health or life if damaged. Durability Makes Metal Reusable Disposable plastic devices definitely have their place in today’s medical world. They reduce the need for sterilisation, which in turn helps keep infection rates and labour costs lower. However, all this plastic waste wreaks havoc on the environment. Did you know that 1/3 of all hospital waste in Australia is plastic, and items like tubing make up a large amount of that figure? If these plastics are burned, they will release toxins into the atmosphere. If they’re simply disposed of, they end up in landfills. If your next medical device will include tubing or something similar, consider whether it needs to be disposable plastic. If not, you should aim to make something reusable, and metal can be a good material choice for this, depending on the device. Given its resistance to chemicals and heat, metal can be sterilised manually or through autoclaves repeatedly without damage. Metal’s strength and impact resistance make these devices far less likely to break than plastics. As a result, metal is the ideal material for high sustainability. Durability Makes Metal Cheaper Given that metals are strong and reusable, it’s no surprise that they can work out to be a cheaper choice than plastics. Hospitals are always looking to cut costs where possible, so a metal device that lasts years is preferable to a plastic device that needs to be replaced after every use. Metal can also be cheaper on the manufacturer’s side for small runs of prototypes and new designs or technologies, as opposed to injection mouldings that require very expensive initial...

How to Choose Accessories for Your Sump Pump

Posted by on 11:58 am in Uncategorized | Comments Off on How to Choose Accessories for Your Sump Pump

If you have a basement in your house, you know the benefits that come with installing a sump pump. Sump pumps keep the basement dry and mold-free during the rainy season by pumping water away into a drainage system. Proper maintenance of your sump pump is essential for optimal performance. One of the ways of monitoring the performance of the pump is by installing the right accessories.  Float switches Float switches help detect the level of water in the pump. They automatically turn on and off as the level of water rises or falls respectively. There are three types of float switches: tethered, vertical, and electronic float switches. Tethered float switches are ideal for use in large sump pumps, or pumps with deep basins. Since the float is large and has a long cord, it de-energizes the pump for extended periods between pumping cycles so that the motor can cool off. Vertical float switches are ideal for sump pumps whose basins are too small to accommodate a tethered float. They have shorter pump cycles than tethered pumps, so they consume more electricity. Electronic switches are more efficient and reliable than vertical and tethered float switches. They do not have any moving parts such as cords; hence, they hardly get stuck or hung-up, a problem that is common with other types of switches. What’s more, they can be used on pumps with shallow or deep basins. Backup sump pump Sump pumps usually fail during the rainy weather when the basement is more likely to flood. If you do not have a backup pump, extensive flooding can occur before you get your pump repaired. If you store items in your basement, they can easily get damaged as well. A backup sump pump is like a secondary or a redundant sump pump that you can install in your basement. Its float switch is designed to operate only when the primary sump pump fails or gets overwhelmed. Sump pump alarm A sump pump water alarm is used to monitor water leaks in the basement and overflowing or leaking pumps. It detects water where it is not supposed to be and goes off. A sump pump alarm can help you identify and repair small leaks or minor sump pump problems before they become a major issue. In some latest models, the alarm can call you when it detects water in your basement. Sump pumps help keep the basement free from flooding all year round. With the right accessories, your sump pump will operate efficiently and give you peace of mind even in the rainy...

Why You Should Use Acrylic Sheets Instead of Glass Panels for Greenhouse Construction

Posted by on 11:39 am in Uncategorized | Comments Off on Why You Should Use Acrylic Sheets Instead of Glass Panels for Greenhouse Construction

The possibility of growing fresh fruits and vegetables for residential consumption (and even for sale) is increasingly becoming a reality for homeowners who choose to invest in residential greenhouses. In order for this possibility to materialize into reality, prospective greenhouse owners must ensure that greenhouse crops grow under optimum conditions. Ideally, the building materials chosen for greenhouse construction should encourage the prevalence of the optimum conditions mentioned above within the greenhouse area. With this in mind, here are a few reasons why acrylic sheets are better than glass panels for greenhouse construction. The “Light” Advantage Acrylic is a lighter material than glass. As such, acrylic sheets will be easier (and often cheaper) to transport to the site of greenhouse construction. Another advantage of the lightweight nature of acrylic sheets is that it makes their installation less expensive than that of glass panels. Being that glass is heavier, the foundation for the greenhouse will have to be dug deeper if it’s to support the heavier weight of glass panels. Similarly, the frames used on greenhouse glass panels have to be more robust than those used for acrylic sheets. More importantly however, the “light” advantage of acrylic sheets over glass panels is seen in the fact that acrylic has better light transmission properties than glass. Therefore, acrylic will allow more of the sun’s light into a residential greenhouse. Sufficient diffusion of light within the greenhouse area is essential for the healthy growth of crops therein. Impact Resistance The use of acrylic sheeting over glass panels for greenhouse construction is also beneficial in the sense that acrylic has a higher impact resistance than glass. Acrylic is said to be up to seventeen times better than glass at resisting the impact of sudden external forces. Better impact resistance means that acrylic sheeting is less likely to suffer physical damage as a result of exposure to sudden impact. As such, acrylic sheets are considered to be more durable than glass panels when used for greenhouse construction. The greater impact resistance of acrylic sheets also translates to them being a safer building material. Even when acrylic sheets suffer physical damage, they’re not likely to shatter and spread debris around the greenhouse. This is a relatively common occurrence with greenhouse glass panels. Shattered glass panels compromise the safety of those who happen to be near the structure at the time of impact and the safety of those who work within the greenhouse area on a regular basis. If you’re considering getting acrylic sheets for your greenhouse, consider contacting perspex suppliers for the acrylic...

Reasons to choose swivel wheels over rigid wheels

Posted by on 9:20 am in Uncategorized | Comments Off on Reasons to choose swivel wheels over rigid wheels

It is necessary that you make the right choice when purchasing castor wheels. Swivel and rigid wheels are examples of castor wheels. Your intention is to get a product that will serve your specific need. Take time to consider factors of maintenance costs, purchasing costs, reliability of the machine, the type of floors to be used, and specific use of your machine. The nature of the wheels will determine the nature of service that you will receive. Swivel wheel castors are a better choice for your use compared to the rigid wheel castors. Response to directional change Swivel wheels have the ability of turning 360 degrees compared to the rigid wheels. They will offer you an easy way of navigation when carrying a load. The weight of your load is well accommodated in all directions and makes movement easy. In addition, rolling ease will reduce cases of injury due to reduced levels of rigidity as compared with rigid wheels. Turning 360 degrees also allows you to move forward and backward with ease allowing use for longer distances. Floor protection Your floor has to be protected and maintained as part of your valued investment. The use of swivel wheels reduces the impact that is exerted on the floor, reducing the damage that may occur. Rigid wheels exert a lot of pressure on floors and increase cases of damage. Avoid extra costs by using swivel wheels to reduce wear and tear on cemented floors. In addition, swivel wheels are easy to use on rough floors and the level of wear is minimized. Rigid wheels take a lot of resistance from rough floors increasing the wear and tear. Therefore, swivel wheels will offer you an option of using them on rough and smooth floors. Durability of the wheels Lubrication of rotating parts is required for your wheel. Friction increases wear and tear in rotating edges. Swivel wheels will offer you the best option as the ease of rotation reduces the amount of friction that is exerted at the rotating edges. You will experience reduced levels of lubrication compared to the rigid wheels which have increased amount of friction. Levels of wear and tear are also high calling for your consistent attention to lubricate the moving edges. You deserve an effective and reliable machine that does not require your constant attention for lubrication to deliver better services. Choose swivel wheels and experience a smooth and easy operation for an extended period. Take charge of your machines and choose swivel wheels for your machine and enjoy better and reliable...

Useful advice to choose a suitable type of trophy for a sporting event

Posted by on 3:12 pm in Uncategorized | Comments Off on Useful advice to choose a suitable type of trophy for a sporting event

While the participants will always have the memories of a specific event or tournament, it is not enough. There needs to be some mark of achievement presented to the winners of the event, as well as to those who have finished in the 2nd and 3rd positions. This is why you need to have a physical reminder of the event, such as a trophy. Even though most professional tournaments and events present prize money as the main award, they will all also present some type of trophy to the winners. By having this as an incentive, the participants of the event will have more enjoyment and pleasure, as they have something to play for. However, there are many different types to choose from, so it can be a quiet daunting process trying to find the one that suits your specific needs the best. While you can worry about the small details later, your first and most important port of call is choosing the best type of trophy that suits your specific needs. Different types of trophies You may want to have space for annual event winners, or it may be a one off award. If an event lasts for several years, the winners should have their names engraved on the trophy, so there should be appropriate room to do so. Individual trophies that are given out to be kept permanently by the winner are easy to customise so you don’t have to worry about space. They can be quiet costly, however, as you have to give out a trophy for a once off occasions, rather than re-using the same trophy year upon year. Perpetual trophies are given to the winner for the period leading up until the next renewal of the event. This is a great way to continuously mark the winner’s achievements and is something to look back on in years to come. It is also a cheaper option as the same trophy can be re-used year after year. Classic Trophies The more classic types of trophies are sculptures or cups. They can be made from a wide range of materials such as metal, wood and plastic. There are many different designs that you can choose from, including different poses of sportspeople that will fit your specific need perfectly. When buying a classic trophy, keep in mind how much space they will take up. Plaque trophies These are a great alternative to classic trophies as the winner does not need a lot of space in their house to hang one up. They are slabs of decorative metal, wood or plastic, which can hang on the wall or be propped up like a picture frame on a desk. Ring trophies Having ring trophies is extremely common in American based sports such as basketball and American football. They will normally be the most expensive trophy type, but they are unique and can be easily stored or worn. This can be a great option for a team that has won a championship, or had some other significant achievement.

3 Important Questions When Selecting Shower Screens

Posted by on 9:40 am in Uncategorized | Comments Off on 3 Important Questions When Selecting Shower Screens

Sometimes, asking yourself the right questions will help you to clarify the choices that you need to make. For instance, you may find it very difficult to choose the right shower screens for your home if you have not asked yourself crucial questions that can help you to clarify the kind of shower screens that you need. This article discusses three key questions that you should think about if you want to select the most appropriate shower screens for your home. How Big is the Bathroom? The size of your bathroom has a lot to do with the kind of shower screens that will be right for you. For instance, small bathrooms usually have limited door space. It would be better to select bi-fold doors for the shower screens installed in such bathrooms. This is because bi-fold doors take up very little space. Size also affects your choice of shower screen design. An example is that clear glass would be ideal for small bathrooms. This is because the clear glass makes the bathroom look larger than it is. Frosted glass would have the opposite effect. Thus, frosted glass is better suited to large bathrooms. How Much Time Do You Have to Maintain the Shower Screens? Many people are constantly juggling several commitments (such as two jobs). This leaves them with very little time to do domestic chores like cleaning the bathroom. Frameless glass shower screens would be very good for such people. This is because such shower screens have fewer surfaces into which dirt can accumulate. It will therefore be very easy for you to clean this kind of shower screen. This is in contrast to a shower screen that has frames. Dirt can accumulate in the tiny spaces between the glass and its frame. Such dirt takes plenty of time to extract during the cleaning process. You should therefore select a shower screen based on how easy it will be to maintain (given the time you have). How Much Privacy Do You Need? Compare these two scenarios; one person lives alone, while another person shares his or her bathroom with several family members. Who will need more privacy? Obviously, the person who uses a shared bathroom needs more privacy. Such a person would be well advised to buy frosted glass shower screens. This is because frosted glass is less transparent. The person who doesn’t share a bathroom can buy clear-glass shower screens. Use the thought-provoking questions above as a starting point to analyse what your needs are before you go shopping for shower screens. The answers to those questions will be instrumental in helping you to choose the best shower...

Why Induction Bending Is the Best Way to Bend Metal Pipes

Posted by on 8:44 am in Uncategorized | Comments Off on Why Induction Bending Is the Best Way to Bend Metal Pipes

Various bending methods are used in the metal construction industry today. In the production of metal pipes, many metal manufacturers often prefer to use the induction bending method. So, why is induction bending the best bending method to apply in the manufacturer of stainless steel, aluminium, carbon steel, iron, alloy steels, titanium and many more metal pipe products? The following points will help explain to you why induction bending stands out in the industry more than conventional metal pipe bending techniques. High quality bends Induction bending is the preferred bending method for bending of metal pipes because the process offers a narrow and focused band heating, which results in higher quality bends with reduced wall thinning and ovality than other types of bending processes such as cold bending. Since induction bending allows for the manufacture of bends with tighter angles and smaller radii, modifications in alignment can be done over shorter distances. Even for bends with thicker walls, the process will ensure a uniform pipe radius is maintained. The pipe can be annealed or tempered and then cooled using cold water to obtain high quality products with minimal defects. Consequently, the general quality of the induction-bended metal pipes product is greater than that of other bending methods such as roll bending, where too much warping arises in most cases. Energy efficiency With induction bending, you can heat a specific portion of a metal pipe so as to reduce the distortion that usually occurs once the bending process is completed. Temperature can be varied depending on the thermal properties of the material so that only the required amount of heat is used. With the straight metal pipe placed in the heating coil at a specific temperature, pressure is exerted using a bending arm to turn the pipe into the sought after shape. Induction bending is an energy efficient bending method because heat and pressure are applied only where they are required. Since there is minimal wastage of energy in the system, energy costs can be minimized significantly. Pipes cures properly and can achieve complex bends The induction bending does not require welding of joints, culminating in bends with smoother surfaces. The process is also ideal for achieving bends with complex designs, e.g. spirals and U-bends. Thanks to induction heating, metal piping cures well. Curing occurs whenever heat is used to initiate or catalyse structural changes in the metal materials. It means that there will be no need to treat the metal pipes after completion of the bending process. For more information on induction bending, talk with professionals, or click here to find out...

Tips and Products to Use to Avoid Unnecessary Conveyor Belt Wear

Posted by on 2:07 pm in Uncategorized | Comments Off on Tips and Products to Use to Avoid Unnecessary Conveyor Belt Wear

A conveyor belt is often found in a warehouse or production facility to help safely and quickly move product around the facility. A conveyor belt can be very large and may move heavy and bulky objects, even those on pallets, which means it may face wear and tear very quickly. To keep your conveyor belts from wearing out sooner than they should, you might note a few simple tips and some products from companies like Britrac (Aus) Pty Ltd that can protect your conveyor as much as possible. 1. Aligners and trackers An aligner or tracker is placed under the conveyor unit and it then reaches up to each side of the belt. The aligner will work to keep the belt on track and perfectly aligned. If the belt should drift to one direction or another, the rolling motion of the tracker will gently nudge it back into place. This can keep the belt from coming off the conveyor itself and also avoid uneven wear on one side of the belt. 2. Cleaners Cleaners are vital for any conveyor belt but especially for those that manage small items in bulk like gravel. These can easily get caught in the ridges and grooves of the conveyor belt where they get tamped down and then cause excessive wear. A cleaner is typically a roller that the belt runs through at the end of a pass and it may have a polyurethane coating that gently pushes away any type of gravel, dirt, oil, and other debris from the belt. You may be able to add special cleaning solutions to the rollers for added effectiveness. This will keep the conveyor belt cleaner and free from damage caused by these materials. 3. Dust filters Dust can be very damaging to a conveyor belt because it can settle on the belt as well as on the rollers and in the motor of the conveyor as well. Production and warehouse facilities may already have high levels of dust, and moving dusty cartons or raw goods that create more dust can mean damage to your conveyor belt. Dust filters can be installed at either end of a conveyor or along the line itself. These filters may work to absorb the air around its unit and filter it before being circulated again. Dust bags may work as a passive dust collation system; they simply provide material on which dust might collect and in turn, it is kept from settling along the conveyor belt or near its motor and other...

Five Tips for Making a Loose Plastic Joiner Fit More Tightly

Posted by on 4:13 pm in Uncategorized | Comments Off on Five Tips for Making a Loose Plastic Joiner Fit More Tightly

If you’ve got a plastic joiner that doesn’t fit tightly, there are a few things you can do to tighten up the connection. First, make sure your pipe and joiner are the right size to be fitted together, and if they are not, replace them. If they should fit together, try these tips to address the looseness: 1. Make sure you have a square cut If you have cut either the pipe or the joiner, it may not be fitting as tightly as possible because the cut is crooked. A straight, square cut allows the pieces to fit as they should. Pull them apart, and if possible, use a power miter saw to square the edges of both your plastic joiner and whatever pipe it is attaching to. If you don’t have a miter saw, use the finest tooth saw you have. 2. Remove debris or manufacturer protrusions Debris caught in your plastic joiners may be preventing them from creating a tight seal. Take apart the existing connection and grab some sand paper. Roll the sandpaper into a tube, insert it in the plastic joiner and twist it until the plastic is smooth. This process removes old solvent as well as other issues. Repeat this process for the inside of your connecting pipe as well as for the outside of both the joiner and the pipe. If there is a lot of dust when you are done, rinse it off and thoroughly dry everything. 3. Use a marker to mark the best alignment Now that everything is clean, smooth and squarely cut, push your plastic joiner and your pipe together. Use a marker to mark when you want the joiner to fit on your pipe. Use that mark as a guide when you put your pipe and joiner together, but apply solvent first. 4. Apply a thin layer of solvent Properly applied solvent can be critical when trying to make a loose connection be tight again. You can buy solvent at most hardware stores — make sure you purchase a can that is compatible with the type of plastic your joiner is made of. Use a brush or cloth to thinly apply a layer of solvent to both the plastic joiner and the pipe it will be joining. Make sure the layer is even — just throwing the solvent on there won’t fix the looseness. 5. Explore transition coupling Transition coupling consists of metal rings that can be tightened by a screw. You slip this over your plastic fitting and pipe and you tighten it to help them stay more tightly together. If the above steps don’t help, try to explore transition...
