20 OctSafety and Electronics for Marine

Taking your boat out in the sea or lake with friends is always fun. The best way to make sure that your boat trip is comfortable and a success is to put safety first. Often, this means that you need to have, in addition to your life vests, your marine electronics in good working order.

One of the more important pieces of marine equipment boaters have these days is their GPS. A GPS can track your course, your distance from the shore, and your exact location, especially important in case you need help out at sea.

A quality marine antenna is also an essential safety component for your boat trip.

When you’re far out to sea, marine antennas allow you to boost your cell phone signal so you can make contact with land.

Having a marine generator is useful for powering many of the electronics avid boaters are used to, without straining the boat’s battery. A generator can power lights, radars and other small appliances. A marine generator is essential as backup for powering all of your needed marine electronics.

Properly charged batteries will prevent overuse of a marine generator. This means that a top-quality battery charger is essential boat equipment for maximizing battery longevity and durability.

There are other marine electronics such as satellite phones, televisions, fish finders and depth sounders that will make for a more enjoyable excursion, but are not necessarily essential for safety.

Quality marine electronics, proper boating instruments and their support systems are important for a comfortable and safe boat trip.

19 OctDie Cutting Tools

Die cutting machines are used to convert sheet or web materials into desired shapes. These are used to process rubber sheets, non-woven textiles and woven cloth. Basically, there are two types of die cutting machines – rotary die cutters and clicker presses. Automated die cutting machines are used for cutting dies with precise and minimal tolerances.

Rotary die cutter, also known as roller press die cutter, is used in the high-speed processing of sheet and web material. The rotary die cutting machines press roller-shaped cutting dies against a web. Web materials are inserted into the rotating roller dies and then changed into desired shapes. Clicker presses employ manual conversion of web materials. This press consists of a wide plate or table with a smaller swing-arm head. For more difficult jobs, full head and traveling head machines are used. The cutting speed of the die cutting machine is controlled by an electronic inverter.

Top performance, high-speed, reliable cutting results and high precision are the essential advantages of a good die cutting machine. The machines are available in several sizes and shapes for various die cutting requirements. Most die cutting machines offer a lifetime warranty and are able to provide a maximum pressure of 10 to 20 tons. The new generation machines come with excellent efficiency and high precision. There are high-speed hydraulic die cutting machines that can make 15,000 to 25,000 cuts in eight hours.

Several common technologies are used by die cutting machines. Some of them are driven by pneumatic cylinders or air-powered. Some machines have hydraulic components. Low-cost devices such as manual presses are perfect for simple applications such as creating identification cards.

16 OctRackmount Chassis – The Chassis to Protect Your Electronic Modules

Used for holding electronic modules like hard disks, and processors, rackmount chassis are frames that can fit into 19-inch racks. They can also hold visualization walls and I/O cards and can fit in one rack unit or 2 or more shelves.

Different types to fit your needs

Depending on your needs or specifications when it comes to the safety of your electronic modules, you can choose from the following different types of rackmount chassis:

o 1U: This can fit in a single shelf on the rack. They are able to support single and dual processors since they are 1.75 inches high. They also have the lowest chassis profiles.

o 2U: This type can cover 2 shelves on your rack. They are capable of supporting quad processor systems and they also have twice the capacity of the 1U. Their depth is almost 24 inches and they are 3.5 inches high.

o 3U or 4U: If you need 3 to 4 shelves, then the 3U or 4U chassis is for you because they are perfect for cluster applications that require the use of many I/O cards, video cards, and high-speed networks.

Things to consider

Whether it is a 1U, 2U, or a 3U/4U, try to make sure that it is compatibility with your rackmount server. You also need to consider the kind of cluster application that you have before you buy one. Furthermore, choose a chassis that is made of aluminum or steel to ensure resistance to heat and extreme changes in temperature. Remember that a durable chassis can do more for the protection of your electrical modules especially during shipping and handling.

16 OctRackmount Cases – Which Rackmount Case Should You Buy?

Rackmount cases are made to fit into the standard 19-inch racks. They can be used to house any electronic modules like disc players and power units, and can be mounted vertically unto rails made of metal on each side of a shelf. Depending on the purpose, some cases can fill a whole unit while others either fit into half a unit only or even two or more. Because rack mount cases originated from mounting systems found in railroad signaling relays, some still call them relay racks. The 19-inch rack format however has remained to be constant even with the changes that have happened with the technology mounted within it. While usable for any purpose, the 19-inch rack is most widely used in the telecommunications, audio, entertainment, computing, and other related industries.

Kinds

Hard-mount rack case: A hard-mount rack case is placed on a rack unit with walls touching the case directly and are best for use with interconnected devices like several power modules needed by UPS systems.
Shock-mount rack case: A shock-mount rack case has a one-inch to two-inch layer of foam in between the rack walls and the case because they are designed to be used on sensitive equipment like optical drives and lead-acid battery modules.

Buying a rackmount case

When looking for rackmount case to buy, take careful consideration of the material that a rack mount case is made from. Depending on what you’ll be using it for, choose a rack mount case material that is best suited for your purpose. For example, if you’re using power modules, aluminum is a good choice as it has better cooling capacities compared to steel ones. You would need a rack mount case with better cooling capacities because power modules generate a lot of heat.

25 SepSafe and Effective Band Saw Cutting and Its Uses

Metalworking, woodworking, cutting plastic and other materials can be done through band saw cutting. This is because a band saw, which is a versatile power tool, can be adopted or designed to carry out these activities. To carry out metal cutting, the blade of the band saw used is either a carbon steel or a bimetal. Carbon steel tool blade, the cheaper option can equally be used on mild steel to cut it, when set to the appropriate speed. As for the more expensive bimetal blades, this can be used to cut hard materials, for example stainless steel. However, making use of a bimetal band saw may be the cheaper option in the long run, if used appropriately as it often outlasts a carbon steel blade of a band saw.

To cut wood, you can make use of carbon steel tool blades on your horizontal band saw or other band saws, which it can be used for (please confirm from sales guide or manual before using it this way). Some manuals that come with band saws designed for cutting wood inform users that they can equally cut metals too. This is often true, but such are soft metals like aluminum, copper, et al.

If you attempt this wood cutting band saw on a stainless steel, which is a denser metal, you will likely destroy the saw blade as a result of the heat generated. This is because a lot of wood cutting band saws possess blade speed that is inappropriate for cutting such metals; as they run faster than required for cutting harder metals.

A tooth pattern on band saws is another way these powerful tools are put to different uses for wood cutting or metal cutting. Without these differences in pattern the versatility of band saw cutting will be somewhat limited in its usage compared to what it can currently achieve.

There are general rules for tooth patterns. For band saws designed to cut wood, it is that fewer teeth per inch makes a faster, but rougher cut; while the direct opposite (possessing more teeth in every inch) will make a smoother, but then slower cut. And with metal cutting band saws, the general pattern rule is that working with thinner materials requires possessing more teeth per inch, while harder materials need fewer teeth.

Metal band saw cutting is done basically through the use of two machines, namely; horizontal band saw mentioned earlier in preceding paragraphs and vertical band saw. Wood cutting also employs the horizontal and vertical model of band saw machines. Horizontal band saw machines are often designed to accommodate one width blades, while vertical band saws can take blades that have various width sizes. Band saw cutting has developed over the years with more innovations expected in years to come.

24 SepAdvantages of PVC Wall Panels

Although these are great wall coverings, they can be expensive — and messy to install and remove. However, there is a solution: PVC wall panels.

PVC wall panels can be a great solution if you want to cover your bare walls quickly and easily — and have them look stylish, too. They’re available in just about any kind of “look” you want, from granite-look to woodgrain, even marble or onyx.

PVC stands for polyvinyl chloride, and is a plastic paneling solution that’s been molded to specific needs. It has several advantages over real woodgrain paneling, for example, or other wall coverings. PVC wall panel includes the following features:

Durability

Unlike real wood coverings or other natural materials, PVC wall panels are durable and very low maintenance. They resist fading and color changes, and unlike wood paneling, for example, they won’t absorb water or rot.

Ease of installation

PVC panels are easy to install. Most PVC paneling today is done as a “tongue in groove” setup, such that they can simply be stapled or nailed through recessed fastening so that the fasteners are concealed. You can also glue PVC wall panels onto walls instead of stapling or nailing. The paneling is lightweight and easy to handle, so that you don’t need special tools.

Variety

You can find PVC panels in just about any color, style, or look you want. That means you can fit wall paneling to just about any decor.

Easy maintenance

Unlike other wall coverings, you don’t have to do anything special to clean or maintain PVC panels. All you have to do is wipe them down with a damp cloth.

Insulation

It might surprise you to know that PVC wall panels are very insulating, too. This can provide a sort of extra insulation for your home beyond that you would normally think of.

Flame resistant

PVC wall panels have the highest fire rating for any interior finish, further ensuring the safety of your family.

Inexpensive

Although you’ll pay a little bit out of pocket for PVC wall paneling, the savings over time as opposed to other wall covering materials is significant. Because they’re very low maintenance, durable, fire resistant, and easy to clean, you can put them up once and enjoy them for years to come, with no muss, no fuss.

Easily changeable

Want to change the look in a room quickly? Instead of having to scrape and repaper (or repaint) a room every time you want a new look, you can simply take down wall panels and put new ones back up, quickly. It’s an easy way to change a look in a room, quickly and easily — no messy paint or paper scraping to deal with.

24 SepPlastic Extruders – Types and Specifications

What are Plastic Extruders?
Plastic extruders are used to create a wide range of items, including plastic tubing, trims, seals, plastic sheets and rods. Extruder is the machine for producing more or less continuous lengths of plastic sections out of a selected type of plastic resin. There are a number of extrusion techniques available such as co-extrusion, offset extrusion, oriented extrusion, overcoat extrusion, cold extrusion, ram extrusion and much more.

The essential elements for a thermoplastic extruder are a tubular barrel, usually electrically heated; a revolving screw, ram or plunger within the barrel; a hopper at one end from which the material to be extruded is fed to the screw, ram or plunger; a die at the opposite end for shaping the extruded mass.

Extruders may be divided into three general types:

* Single Screw Extruder

* Twin or Multiple Screw Extruders

* Ram Extruder

Single screw extruders and twin screw extruders are the most widely used extruders. The screw that is used to push the resin out of the die is the important component of a screw extruder. In the earlier days rubber screw were used but the rubber screw was not able to give enough amount of shear into the polymer. Therefore, screws were designed that would start deeper in the feed and gradually taper shallower in the metering section to apply more work on the polymer as it was going from the feed to the discharge.

Basic screw design
The screw is usually contained inside a tight fitting barrel driven by a variable speed motor and gearbox. It is a highly efficient device capable of processing several tons of plastic per hour, even in modestly sized extruders. The screw is divided into three division the feed section, the compressor and the metering section.

The feed section of the screw mechanism stores and delivers resin pellets from a gravity fed hopper into the jacketed screw to begin the plastic longitudinal movement. Screw threads move the plastic using axial rotation. Within the barrel, heaters help the plastic develop a tack to increase its friction against the barrel wall. Without this friction the plastic could not be conveyed forward and would merely rotate inside the screw.

In the transition or melt stage, the root diameter of the screw increases while the height of the flight decreases. The resin is melted here because of compression, shearing and heating produced in the barrel. Now the melt moves to the metering section, where the screw diameter remains constant. The melted plastic which is under high pressure now is pumped into the extruder die.

Barrier Screws
The resin is sometimes not completely melted in the basic extrusion screw. The barrier screw in designed to counter this problem. Additional flights are attached to the transition section so as to separate molten and solid plastic to different channels. As the solid pellet moves forward it melts due to shear against the wall and thus melts and flows into the liquid channel. Thus the solid channel narrow gradually and the liquid channel widens.

Mixing Screws
When mixing two different additives, a more efficient way is to mix extrusion materials with twin screw extruder. In this method two screw rotate with or against each other and have special mixing features, such as kneading blocks and forward and reverse capabilities. Some single screw systems can, however, be used for mixing.

Though general-purpose screws are available, different plastics require differently calibrated extrusion screws. The length-to-diameter ratio, pitch, length of each zone and helix angles of a screw must all be matched to the plastic type being used. The screw must also be designed to suit a specific type of die.

Extrusion screw design has been improving over the years, with new innovations and ideas that help in perpetually adjusting the process so as to meet the needs of specific applications.
