4 Uses of Glow Discharge Plasmas During Metal Fabrication

Posted by on Oct 25, 2016 in Uncategorized |

A good metal fabrication shop should always look out for newer ways to perform different tasks during the fabrication process. This article discusses how a glow-discharge plasma machine can be helpful during surface cleaning or treatment during metal fabrication. Use this information to make an informed decision about the suitability of this technology in your fabrication shop. Surface Degreasing Glow discharge plasmas use a low current to heat air particles until they release their ions. Those ions move towards the material that is being cleaned and cause it to become hot. That resultant heat can cause any grease that was used during previous fabrication stages, such as sheet metal bending, to melt. The material therefore becomes clean and dry once the glow discharge plasma has vaporised the grease. This makes the product to be ready for delivery to the client in a shorter time than it would take other surface cleaning methods, such as using an acid bath. Surface Passivation Some metal fabrication processes require the surface of the product to be rendered inactive. For instance, your client may require his or her zinc components to be passivized so that they form an oxide layer on their surface. The glow-discharge plasma machine can do this very well by heating oxygen gas within the plasma chamber. The ions released form an oxide layer on the surface of the components to the passivisation standard requested by the client. Removal of Oxide Layers Some situations may require you to remove the oxide layer from a material before further fabrication processes, such as powder coating, can be done. This objective can also be achieved by using the glow discharge plasma. This can be done by increasing the heat inside the plasma chamber so that the oxide layer on the surface of the material melts away. The fabricator can use an inert gas, such as argon, during this process so that little or no oxygen is allowed to react with the material. Removal of Particulate Deposits Metal particles may have become embedded in the surface of the component that has just been fabricated. Such particles can accelerate corrosion or cause the material to crack later on. Those particulates can be removed by heating the component using glow discharge plasmas. The particulates will be consumed in the heat so that the component is left free from any damaging particles on its surface. As you can see, glow discharge plasmas can be used for a variety of purposes within your fabrication shop. You can read more about metal fabrication to better determine what steps you should be...

What Type of Pool Fencing Should You Choose For Your Property?

Posted by on Sep 28, 2016 in Uncategorized |

Having a pool on your property usually means that you’re legally obligated to put a fence around it; this keeps out children and pets and helps to avoid tragic accidents when you’re away. Above and beyond the legal requirements, you want to ensure you choose a pool fence that is durable yet attractive while still being safe. After you’ve checked your local city codes to find out minimal requirements for pool fencing, note a few additional tips to help you decide the best fence for your property. Protection from debris One advantage of a mesh or glass fence is that they help to keep debris away from the pool more so than iron bar fences. If you live in a very windy area, or have neighbours who use high-powered leaf blowers and lawnmowers that always seem to blow grass clippings toward your pool, a mesh or glass fence can be best. The debris will then pile up against the fence before it reaches you pool, keeping it cleaner and resulting in less work for your pool filter. This is also good to consider if you don’t have a pool cover and need added protection against this debris landing on the water’s surface. Safety If you need to keep your pool protected from uninvited visitors, avoid a standard hurricane or cyclone fence. These offer a good toehold for climbing. A glass fence means there’s less chance of someone scaling the fence. A metal fence with pointed finials at the top can also discourage anyone from trying to climb the fence, and a tall vinyl fence, with its smoother surface, may also be more difficult to scale. Material Wrought iron is very durable but may be prone to rust when exposed to the water and chemicals from a pool. It may need refinishing on a regular basis. A glass fence doesn’t rust or corrode, but it may show watermarks and fingerprints, and it needs to be cleaned on both sides. If your property backs up to a nature area, remember that wildlife cannot see your glass fence so you may need to constantly clean off paw prints, nose marks and the like.  Vinyl is very durable and virtually waterproof and stain resistant, which is why it’s often chosen for commercial pools. PVC is also very lightweight and watertight. As it’s typically used for plumbing pipes, you know it will stand up well against constant exposure to pool...

Five Signs You Should Integrate Self-Cleaning Sheet Metal Into Your Product

Posted by on Jul 18, 2016 in Uncategorized |

Scientists have recently developed self-cleaning sheet metal. If you buy sheet-metal to make a product that you sell to clients, you may be wondering if it’s time to think about utilizing self-cleaning sheet metal in your products. Here are a few signs that you may want to include self-cleaning metal in your processes. 1. You make products for the food industry. If you make metal work surfaces for commercial kitchens, vats for milk processing plants or any other products for the food industry, you may definitely want to think about incorporating self-cleaning metal into your products. Mimicking the properties of the lotus leaf, self-cleaning metal makes moisture bead up on its surface, preventing bacteria from staying there. 2. You make products for hospitals or other facilities with high levels of bacteria. Self-cleaning sheet metal has a rough surface that encourages the formation of little pockets of air. The air gets in between bacteria and the surface of the metal, preventing bacteria from sticking. As a result, it is no longer necessary for the people who own the metal to clean it as often, and this can be especially helpful for facilities such as hospitals or aged care homes as well as for toilets in offices, restaurants and shops. 3. Your clients crave green, energy efficient solutions. If your typical client loves green products and energy efficiency, self-cleaning sheet metal allows you to sell them that concept. When the metal cleans itself — whether it is in a kitchen, a hospital or anywhere else — it saves your client time and helps to boost energy efficiency and protect the environment. In most cases, your clients won’t need to use as much water because they are cleaning less. Similarly, they won’t have to rely on cleaning chemicals which can be bad for the environment. Instead, the shape of the sheet metal takes care of cleaning. 4. You pride yourself on offering innovation. If your brand image is about traditional products made with traditional methods, you may prefer the sleek look of conventional sheet metal than the possibility of self-cleaning metal. However, if your brand is all about innovation, then this new product needs to be on your radar. It may be just what you need to impress your clients. 5. You have the ability to mock up a single demo. Before you integrate self-cleaning metal into your production process, you may want to purchase a sample and mock up a demo. That way, you can see if you like the result. If you cannot make a demo, you may not want to switch until you can explore the ramifications this type of sheet metal will have on your final product.   ...

Corrosion Types That Can Occur On Steel and How to Deal With the Corrosion

Posted by on Feb 11, 2016 in Uncategorized |

Stainless steel is typically corrosion resistant and holds up well in most environments. However, there is a limit of the corrosion resistance of any given stainless steel depending on its constituent elements, which means that every grade will have a slightly variant response when exposed to corrosive environments. For this reason, you need to be careful when selecting the grades of stainless steel for different applications in your home or workplace. To help you reduce the likelihood of corrosion and staining, here are forms of steel corrosion you should know and ways you can avoid them:  Pitting Corrosion Stainless steel contains chromium, which forms a surface film or layer of chromium oxide on contact with oxygen. This layer is passive because it makes the surface of the stainless steel to lose its chemical reactivity.  However, chemicals especially those with chloride ions, found in everyday materials like bleach and salt can attack this passive layer, allowing corrosion to start. This type of corrosion, known as pitting corrosion, refers to a local break in this passive layer that can be provoked by electrolytes rich in chlorides. To prevent this corrosion, keep your stainless steel material away from prolonged contact with chemicals. However, in the event that a pitting hazard is known, for instance, where both stainless steel and chlorides will be in contact, choose a grade of steel such as molybdenum-bearing stainless steel that will be more resistant to the chemical attack.  Galvanic Corrosion Galvanic or bimetallic corrosion can occur when dissimilar metals come into contact in common electrolytes such as water or other solutions, setting up a galvanic cell. If there is a flow of current between the two, the anode, the less noble metal, will corrode at a faster rate than it would have had the metals not come into contact (a noble metal is one that is resistant to oxidation and corrosion in moist air). The rate of corrosion will also depend on factors such as the composition and temperature of the electrolyte, and the areas of the metals that are in contact. Greater attack on the anode will occur with larger areas of the cathode (more noble metal). Therefore, avoid carbon steel bolts in any stainless steel member because the ratio of the stainless steel area to that of the carbon steel will be large, meaning that the carbon steel bolts will be subject to aggressive corrosion or attack. Alternatively, you can use non-metallic insulators like rubber to separate the metals. Crevice Corrosion Stainless steel needs an oxygen supply to ensure that the passive layer forms on its surface. Therefore, tight crevices hinder oxygen access to the stainless steel, making it vulnerable to attack. These crevices can occur between washers and nuts and around the shank of a bolt or the thread of a screw. To prevent this, seal the crevices with flexible sealants. For further assistance, contact professionals, such as those...

6 Reasons Why You Need Porcelain Tiles For Your Bathroom

Posted by on Jan 25, 2016 in Uncategorized |

When building or remodelling your house, the bathroom is a place you wouldn’t want to go wrong. This means that identifying tiles for your bathroom are among the major tasks you’ll face. Perhaps you’ve been thinking about bathroom tiles ever since you decided to construct or renovate your home. There is a variety of options and materials you can use for your bathroom tiles, including vinyl, wood, stone, etc. Whether it’s your bathroom floor tiles, shower tiles, wall tiles, or splashback tiles, you need to make the right choice that will give your bathroom an elegant look while standing up to your daily use.  For this reason, here are 6 reasons why you may want to go for porcelain tiles. Stain Resistance Porcelain has a natural stain resistance feature. With the ability to repel liquid penetration, staining agents won’t readily penetrate through this material dimensionally. This effect can be even more enhanced or dramatic when your porcelain tiles are glazed, making it almost impossible for the surface of these tiles to be discoloured. This makes porcelain tiles suitable for your bathroom. Durability Porcelain is denser than its comparable counterparts because it’s made from refined clay and fired at higher temperatures, making it durable. If installed correctly in your bathroom, it will last for long. Low Maintenance Porcelain is easy to maintain, especially because it’s resistant to stains and doesn’t need covering for water resistance. It is non-porous and has high resistance to slipping. For this reason, cleaning is an easy task because you can simply clean spills using water, a detergent if necessary, and a damp rag. Moreover, sweeping regularly will keep loose debris off your floor. Moisture Resistance Porcelain is less prone to moisture absorption because of its high density. This makes it the ideal option for your bathroom. Resistance to Wear and Tear Porcelain is a hard material, giving it a tendency to resist cracking from physical impacts. The higher breaking strength than other materials makes it more versatile for use in your bathroom. In addition, the hardwearing material can resist scratches, chipping, and fading. Since your bathroom is a place that can be used more than once in a day, this particular feature of porcelain tiles makes them a more flexible option. Options Porcelain offers you a variety of styles to choose from because the tiles can be made to look like wood, slate, granite, and marble among others depending on what you’d prefer....

Common Drill Bits You Can Use in Your CNC Metal Fabrication Shop

Posted by on Dec 21, 2015 in Uncategorized |

Computer numeric control (CNC) fabrication machines help to make products more precisely since they rely on computer commands to fabricate products. One of the tasks that CNC machines can do is drill holes during the fabrication process. This article discusses three kinds of drill bits that can do that work. Use this information to make an informed decision as you select the most appropriate drill bits for your newly installed CNC machines. Indexable Drill Bits This drill bit has ceramic inserts that work as cutting edges. The drill bit also has a very hard cutting tip that makes it unnecessary for you to sharpen the drill bit. The biggest advantage of this type of drill bit is that it is very fast. The drill bit also has the capability of making holes that are several times as wide as the drill shaft. Spade Drill Bits These are made out of two parts. One part is the metal body that is attached to the CNC machine. The second part is the drill tip that is clamped into a slot found in the metal body that has been attached onto the CNC machine. The biggest advantage of this type of drill bit is that it is equipped with special notches on its sides. Those notches help to remove the drill debris so that it does not create a clog in the area where the drill bit is operating. It is also easy to replace a worn drill bit. This is because you only have to remove the tip and clamp a fresh one in its place. Ejector Drill Bits These are ideal when you want to drill deep holes inside the material that is being machined. The drill bit can have a single head or it can have several heads. The version with several heads usually has brazed carbide bits in the middle so that they reinforce the action of the outer tips that may not be operating evenly due to encountering different magnitudes of resistance in the machined material. Ejector drill bits can also produce holes that are much larger than the drill shaft of the CNC machine. Work with a supplier of CNC milling machines so that you select a collection of drill bits that will be effective for the different drilling tasks that you perform at your fabrication shop. You may also try the different drill bits before you settle on a particular type that delivers satisfactory results on a consistent...

Important Factors to Consider When Choosing Castor Wheels

Posted by on Dec 4, 2015 in Uncategorized |

Castor wheels are used in vehicles, such as dollies, shopping carts, dumper bins and so on to ease movement of loads. Therefore, if you are thinking of fitting your vehicle/ cart with castor wheels, below are some factors you may want to take into account. Temperature it will be exposed to Before getting your wheels, you need to determine the amount of heat they will be subjected to. This will enable you to choose a wheel of the right material. For very hot temperature sites, you may want to acquire cast iron castor wheels. The cast iron is hardened and can withstand temperatures of up to1500 degrees Fahrenheit. Moreover, you can also get phenolic castor wheels made of high profile polyurethane, which is specifically designed for high temperature conditions. For extremely cold temperatures, you may opt for plastic or soft rubber wheels, since they are less susceptible to freezing than the former. Floor surface When buying castor wheels, identify the texture of the floor surface they will be used on. You may want to have a wheel surface texture that is opposite to that of the floor. For instance, a rigid rubber castor wheel would suffice for a very smooth floor. It consists of a wheel mounted to a stationary fork that restricts the vehicles motion to a straight line. Moreover, the rubber increases friction, thus grasping the floor more. For rougher surfaces, a smoother castor wheel, such as nylon glass, would do. Since these castors are mostly used for heavy loads, they exert plenty of friction on the surface. Therefore, they need not be rough to function properly. Impact it will be exposed to If the vehicle will be subjected to high impact with ground surfaces, it would be best to find castor wheels with tough and resistant material. For instance, cast iron wheels are commonly used for industrial dumper bins due to their hardness. Moreover, you may also go for nylon glass reinforced castor wheels, whose material has been reinforced to withstand high impact situations. Control For more control, the best solution would be a swivel castor. It has a swivel joint that allows the wheel to roll in any direction, thus enabling you to make tighter turns. In addition, you may also opt for braking and locking castors. These allow you to control the speed of your vehicle and can be useful when you need to keep the vehicle stationary. For more information about your options for castor wheels, contact a local...

Precautions to Take When Replacing a Worn Hydraulic Hose

Posted by on Nov 20, 2015 in Uncategorized |

Over time, hydraulic hoses from companies like Hose Mania in industrial machinery can wear out and start leaking. Such signs of wear can reduce machine efficiency. This makes it necessary to replace those hoses before they pose safety risks to employees. Read on and discover some important precautions that you should take as you perform your first hydraulic replacement task. Disable Any Attachments Supported by the Hydraulic System It is important for you to lower any equipment attachments that rely on hydraulic power to operate. For instance, you may wish to replace a hose that supplies lift equipment with hydraulic fluid. The attachment supported by the hydraulic system may come crashing down on you if you remove the hose that had the pressurised fluid that kept the attachment suspended. That is why you need to lower that attachment before you attempt to replace the damaged hose. Prepare to Catch Spilling Hydraulic Fluid Have you ever been drenched by a torrent of used hydraulic fluid? You don’t want to experience what it feels like to have all that fluid on your body. Avoid this unpleasant experience by relieving the pressure in the machine that uses the hydraulic fluid transported by the hose you wish to replace. Use the manual to find out where the pressure relief valve is found. Next, get a bucket and direct the end of the hose that you have just removed towards that bucket. This will channel all the residual fluid into the bucket. Continue with the replacement process once all the fluid has drained out. Plug the Fittings and the Hose Some people only plug the fittings (such as the hydraulic valves which are exposed after you remove the industrial hose) where the old hydraulic hose was. They forget to plug the ends of the new hose. This oversight can expose the hose to contamination by dust and other forms of dirt during the process of routing it through the machine until it reaches its position. Use the cap that came with the hose to plug the end of that new hose. Alternatively, you can tie a clean rag on the open end of the hose so that dirt is prevented from getting into the hose. Each piece of equipment has a manual that details how a hydraulic hose should be replaced once it wears out. Follow those guidelines, as well as the tips above and you will soon be adept at conducting industrial hose...

Questions to Ask About Hiring a Shipping Container

Posted by on Oct 30, 2015 in Uncategorized |

Renting or hiring a shipping container can give you the shipping options you need without the expense or hassle of maintaining your own container or finding storage for it when it’s not in use. It’s also typically the best choice for one-time rentals and companies that don’t use shipping containers very often. Before you decide on a container or a container hire company, note a few questions to ask and consider so you know you get the right choice and use the container properly. 1. Ask what was shipped in the container most recently Some shipments may leave very strong, foul odors in a shipping container and the items you’re shipping may tend to absorb those odors during shipment. Note however that most foodstuffs may not leave an odor since they need to be frozen or packed properly so they don’t rot during shipment, and in turn, they may not leave behind bad smells. Furs, certain feed or grain, and items like these are often the most offensive when it comes to bad smells, so be sure you ask about previous shipments and about their policy of returning the container if it does arrive with a bad odor inside. 2. Note the ground surface on which the container can be stored Not all containers are good for storing on soft ground as they may be so heavy that they tend to sink in. If your facility doesn’t have a concrete slab on which you’ll store the container while it’s being loaded, ask about a lightweight aluminum or plastic or another option that is better for the ground surface that is available. 3. Consider the clearance needed for doors You need to ensure you choose a shipping container that fits your property including the clearance needed for swing-out doors. If you do not have enough clearance for the doors to open fully and fold back all the way against the container without obstruction, ask about a container with a rollup door instead. Even if these are more expensive to rent, you may need it to ensure you can easily access the container. 4. Ask if you need a permit to keep the container on your property If you’ve never rented such a container before, you can ask the rental agency for assistance in this area. They will usually be familiar with your local regulations about permits, if needed, and can help you with this paperwork so that you have it available when the container...

Noise Making Refrigerators: How To Deal With Sounds Made By Refrigerators

Posted by on Sep 25, 2015 in Uncategorized |

If you feel like you are  losing your mind because you hear strange sounds coming from you kitchen in the middle of the night, it’s not you.  The culprit could be your refrigerator. Sounds generated by refrigerators can be quite annoying, and until recently, manufacturers and scientists alike were also baffled by some of these sounds. Here are the most common sounds that emanate from a refrigerator and how you can deal with them. Cracking Sounds According to Dr Hasan Koruk, a mechanical engineer, these sounds are generated by the expansion and contraction of fridge components; as the temperatures of the components fluctuate, they cause stress on the components, and hence the expansion and contraction. The heater panel in particular is the main source of the cracks. Therefore, by changing the panel to a more appropriate design, you can minimize the rapid temperature fluctuations, and thus, the expansion and contraction processes. For instance, changing your heater panel to one that has stiffeners and ribs can dampen the sound that it generates. Squealing and Chirping Sounds These noises come from the inside of the refrigerator and are associated with motors of the cooling fans. You can carry out a simple test to determine where the problem lies by opening the door of your refrigerator and holding down the fan switch. If the sound persists while holding the switch, the problem might be a defective fan motor. Another test is to take the evaporator cover off – the cover is usually located at the bottom or the back of the freezer. You should have a clear view of the fan once the cover is off, and you can easily determine what the source of the noise is. If the fan is defective, the best remedy is to have a technician change the fan for you. Buzzing and Clicking Sounds These sounds originate from the outside of the refrigerator, where most moving parts are located. The condenser fan is the major cause of these sounds. It accumulates lint and debris that make the sounds, and hence it should be your main concern. A technician can locate the condenser fan and clean it with specialized equipment. But at times, there could be nothing wrong with the components of your refrigerator. The sounds may be due to ice collecting around the shroud of your evaporating fan. When the blades are rotating, they strike the ice and generate noise. Check for ice around the fan and take them out. Remember that the evaporator cover is either at the back or at the bottom of your...
