If you need to manufacture a large number of identical components, you will likely want to use a computer program to do so. A computer program eliminates all margins of error and helps you create multiple, identical objects with zero variation in design. However, there are a couple of different computer models that might interest you. The first is CNC or Computer Numerical Control. The second is 3D printing. Each offers unique benefits, but your individual project will likely determine which is best for you. Consider the following before making your decision.
How They Differ
The most obvious difference between CNC machining and 3D printing is the way they create objects. A CNC machine takes a raw block of material and sculpts it using routers, mills, grinders, and lathes. A 3D printer, on the other hand, starts with nothing. It uses filament material to create or print an object from scratch. Both work off of similar software and code that is easy to manipulate via computer screen. The interface is much like CAD, where you can easily manipulate variables with a click of the mouse.
Types of Materials Used
CNC machines and 3D printers vary greatly when it comes to the types of materials you can use. Since CNC machines sculpt all sorts of raw materials, you can use just about anything. Common materials used in CNC machining include, wood, acrylic, foam, wax, aluminum, copper, steel, and so forth. Printers of the 3D variety are limited when it comes to the types of material that can be used. Any material used has to fall into one of two categories: thermoplastic or resin. While you may be able to mix particles of metal and sawdust with the materials, you will not get a truly wooden or metal object.
Design Limitations of Each
CNC machines cannot usually create objects with small internal pieces whereas 3D printers can. When it comes to precision, CNC machines usually perform better. They can also create objects faster. It can take hours for a 3D printer to build an object from scratch. You can create the same object in a lot less time with a CNC machine.
CNC machines and 3D printers can be used for similar projects, but they are not created equally. The one that works best for your project depends largely on what type of project you want to complete and the raw materials you would like to use.

Block parties offer a great way for the neighborhood to come together and share a meal, but the mess left behind by the food and festivities can be a lot to deal with. Use this guide to help keep the block tidy and ensure proper sanitation throughout the event.
Rent A Dumpster
Rent a dumpster from your local dumpster rental service that everyone can use to dispose of trash and food waste. This will prevent you and your neighbors from filling up your residential trash cans, which can be a particular issue if your block party is held on a day that isn’t trash day. If you rent one dumpster, place it at the end of the block, or if you rent two, put one at either end for easy access. Arrange with the dumpster rental service to have them dropped off and picked up the same day so you can ensure the block is clear and ready for traffic at the end of the event.
Rent Recycling Containers
Whether you rent a recycling dumpster or a few recycling cans, these receptacles can help to keep garbage to a minimum and improve your overall impact on the environment. Be sure to have signs printed up to remind attendees at the party to place plastic cups and silverware, aluminum cans and cardboard in the recycling containers, and place the containers throughout the event space.
Rent Portable Toilets
You and the other homeowners on the block may not be keen on the idea of having everyone use the restrooms in your houses, so instead consider renting a few portable toilets and a portable hand washing station. These can be placed next to your dumpster to keep them away from the main party area. Just as with your dumpsters, be sure to call ahead to inquire about same-day pickup and drop off.
Put People In Charge Of Litter Duty
Assign shifts for cleaning up litter throughout the event. Everyone assigned to a shift should be in charge of picking up and throwing away any litter from the party left in the street. If all the people assigned stick to their duties, you should be left with a clean, clear street at the end of the party. To keep everything fair and organized, create a sign-up sheet ahead of time, and keep the shifts short so everyone can enjoy the party.
Work with your local dumpster rental like TCM Sweeping and Disposal and portable toilet rental companies to get the items you need to keep your block party clean and sanitary, and give everyone a more enjoyable experience at your event.
When you go to the store, you probably place your fruits and vegetables in the plastic produce bags. Those are great for transporting your produce home from the store. However, if you want your fresh fruits and vegetables to last longer, most of them should be taken out of the plastic bags as soon as you get home. Ethylene gas, which is a naturally occurring gas, can build up inside the bags. When that happens, you’ll notice that your food goes bad faster than it should. Here are four steps you can take to extend the shelf life of your fruits and vegetables.
Drag Out the Old Pantyhose
If you’re going to be storing your onions, don’t store them with the rest of your produce. Instead, put a pair of old pantyhose to good use. This simple method will help keep your onions fresh. Place one onion in the pantyhose. Tie a knot to secure the onion. Place another onion in the pantyhose and tie another knot. Continue filling the pantyhose with onions. Be sure to tie a knot after each onion. Once you have the onions secured, hang the pantyhose from the ceiling of your pantry or broom closet.
Flood Your Greens
If you’re tired of you’re lettuce wilting and turning to slime before you’ve had the chance to eat it, you’re probably storing it wrong. Take your lettuce out of the produce bag and place it in a plastic storage bowl. Fill the bowl with cold water and place the cover on the bowl. Your lettuce will stay fresh.
Clean Those Berries
Berries should be cleaned as soon as you get them home. Remove the berries from their containers and rinse them off with fresh water. Next, fill a spray bottle with water and add about 1 cup of vinegar. Spray your berries with the solution and allow them to sit for a few minutes. Rinse them with fresh water and place them in a storage container. Cover the container and place them in the refrigerator.
Freeze Your Herbs
If you’ve got herbs that you want to keep fresh, get them prepped and ready to go before you put them away. Dice your herbs like you would for your favorite recipes. Place the herbs in ice trays, filling each individual ice slot with herbs. Pour olive oil over the herbs and place the ice trays in your freezer. When you need your herbs, simply remove one of the pre-made herb cubes.
When it comes to keeping your fruits and vegetables fresh, you want to forego your plastic produce bags. The simple storage tips provided here will help your produce stay fresh longer. Be sure to recycle your produce bags the next time you go to the grocery store. To learn more, contact a company like KNF Corporation.
When your construction site needs to consistently stay organized, neat and easily accessible, the issue of how to do so can become a problem. Fortunately, there are a variety of storage bins that are both easy to use and ideal for the specific needs of construction sites. Therefore, it will be very helpful to learn the following information about your storage options.
#1-The Heavy Duty Bin
While a plastic bin could easily be sufficient for storing plastic and other lightweight items, you already know that the majority of your items will be heavy enough to warrant special considerations. One option is a heavy duty bin, and there are different choices you have available.
For instance, you can choose a bin made of fiberglass, which is sturdy and still does not weigh too much. By using a unit made of fiberglass, you will be minimizing the loads that your workers will be lifting and transporting. Alternatively, you can also use bins made of metals like chrome and steel. They are good when you need an extra big container for your construction products, but they are likely to be more expensive and heavier.
Once you know what material your new bins should be made of, you can determine how you want to store them. When space is an issue, stacking bins are a good choice. However, when choosing a new stacking bin, it is a good idea to look to the total weight that any one bin can safely maintain. If the bottom unit is acting as the support system for the bins above it, it is possible that it could crack under the extra weight, thus resulting in damage to the bins and the items being stored.
If that could be a problem, you may want to look into reinforced shelving units. They would allow each bin to be placed on to individual shelves. The shelves would then carry the burden of support, up to the pre-determined weight of the entire unit.
#3-Bins On Wheels
A third option to consider is the unit with steel casters. It is particularly helpful because it is so easy to move. However, you should make sure to also know the total weight that the unit is rated for. Even if it looks remarkably similar or identical to bins you are using somewhere else on the construction site, the steel casters may be able to support less weight than the bins themselves.
Fortunately, you are likely to find that the availability of different sizes for casters will vary. Therefore, you are sure to find the right bin with adequately rated casters to quickly move your construction materials from one area to the next.
In conclusion, construction sites have unique needs, given the weight and value of many of the items being stored throughout a project. When you need to assure that your valuable items can safely be stored and easily accessed from one day to the next, you should consider the storage bin options listed above. For more information, you can check out the sites of local storage bin retailers.
Saltwater fish farm owners have several challenges facing them when it comes to water pumps and maintaining the freshest aquatic environment for fish and other sea life like crustaceans. When your aquaculture environment becomes soiled with fish deposits, your stock will die off, leaving you with expensive profit losses. Learn more about the reasons you need to invest in a high quality water pumping system for your saltwater fish farm.
Saltwater Poses Special Challenges For Pumps
The pumps you use in your fish ponds must be high quality and designed for constant, long-term use in saltwater conditions. Saltwater will corrode metals fast, leading to rusting that can leave the average pump unworthy. Choosing pumps that are design to resist saltwater corrosion is smart and a great investment in your hatchery. If you invest in water pumps that are not designed for use in saltwater, you risk your system breaking down when the pump’s materials become corroded, causing backup that can be unhealthy and kill your fish stock.
The Medium In Saltwater Fish Hatcheries Is Thick
The waste from fish in your hatcheries can clog up a water pump not specially designed for it. When a water pump for a pond become clogged, the ammonium in the water that comes from fish waste becomes deadly to the the living fish. When your pumping system is unable to filter through thicker mediums like water contaminated with solid fish waste, it can become inoperable and cause your ponds to become stagnant with dirty water that will can kill your fish stock. Water pumps are available that are specifically designed for using in fish hatcheries and are able to pump thickened waste water.
Constant Use Can Cause A Lot Of Wear And Tear
Only the highest quality water pumps are good for fish hatcheries because of their needs for constant water pumping. If your pump is poorly made, it can stop working. When the pumps stops working in your ponds, the water can quickly become low quality and the fish cannot breathe in it. The highest level of oxygenated water is best for your stock fish to survive. The minimum flow recommended for water pumping systems is 500 gpm. If your pond is is large enough, you will need a system pumping at least 500 gpm day and night.
Running a successful fish farm depends a great deal on the efficiency of your water pumps. Take the time to lean more about the water pumps you can count on because the time you invest in doing so will be well worth it. For more information, contact companies like http://www.compressor-pump.com.
When most people think of cooling towers, they think of the hyperboloid towers that are responsible for cooling nuclear power plants. These massive towers are iconic symbols of the nuclear age, but they are not the only cooling towers in the world. In fact, cooling towers come in all shapes and sizes, not just the massive cones associated with nuclear power. Regardless of what size cooling towers your building or property has, these towers need to be kept clean. Here are cleaning methods for some common sizes of cooling towers and what you should expect when you hire outside cleaners to address your cleaning needs.
Pressure-Washing the Massive Towers
Massive cooling towers are so big that several hundred people could climb down inside them. Once inside, they are frequently comprised of several vertical and horizontal panels and fans. A tower of this size has to be shut down and purged before treatment and maintenance crews can climb down inside and clean them. Typically, a commercial pressure washer is the most effective because it blasts thermally-baked on dirt and debris from the internal panels of the towers. There may also be some devices you can buy (called “scrubbers”) that can help keep the towers somewhat clean in between service periods.
Rotary Cleaning Tall and Narrow Towers
While some cleaning technicians may still be able to sneak down inside these tall and narrow towers, it is often easier to just send a large rotary cleaning tool up or down inside the stacks. Of course, special scrubbers are more ideal for this type of cooling tower, since it helps eliminate the need for technicians to enter the towers and try to manipulate cleaning tools up inside the towers. The scrubbers themselves will need regular maintenance, but they reduce the number of visits your cooling towers will need from/with cleaning technicians.
Manual Scrubbing of Short, Stubby Packaged Cooling Towers
Packaged cooling towers are boxy in appearance, and they are typically used to cool small industrial or apartment buildings. They can be found on the roofs, where the steamed water escapes into the higher air. Usually, they are made of a hard plastic resin box with the cooling components just inside and the attached pipes are located outside this unit. Treatments and cleaning for these towers is almost always manual in nature because the towers can be dismantled and opened easily. After the parts are cleaned, the technician puts the parts back together and closes the main box of the tower back up again.
This is your first home and, while the previous owners took good care of it, you’re starting to uncover little problems. The toilet keeps running after it’s flushed until you jiggle the handle. This is a good way to get your “feet wet” with your first DIY project. Replacing the toilet flushing mechanism takes about an hour with simple household tools. Here is what you need to know to do this project and have your first DIY homeowner project scratched off of your list.
Supplies You’ll Need
Knowing When You’re In Over Your Head
A good homeowner knows when they have a problem that requires expert help. If you encounter any of the following problems, have a local plumber help with this project.
Many who are environmentally conscious practice recycling to support better use of our resources. Plastics are one of those frequently recycled products. You may wonder what actually happens to all those jugs, bottles and plastic containers you tote to the curb in your recycle tub.
One way that waste plastic is recycled back into circulation is through melting it down to produce new products. That process is called injection molding. To help you better appreciate recycling your plastic waste, here are the basics of the injection molding process.
Two Halves to a Mold
Injection molds are made of two metal plates, each making up one-half of a plastic product. These are separated into two pieces at a parting line. The A and B plates make up either the top and bottom of a product or two halves of a solid item. The parting line is important because this is where the mold is broken apart once the plastic has hardened into a new toy, tool, or other plastic product.
The Injection Mold Process
Fluid plastic resin is poured into the injection molds through a small opening called a sprue. The sprue is located in the A plate.
From the A plate the fluid resin moves throughout the mold through runners. Runners are like little tunnels that distribute the plastic evenly to the different part of the mold.
Within each of these cavities the resin flows around wall-like barriers, or protrusions called cores. The shape of these cores is what makes the shape of the final product.
The resin injected into the sprue, through the runners to fill up the cavities in the injection mold is called a shot. The amount of fluid plastic resin in each shot will equal the amount of final plastic that makes up whatever the new product is going to be.
If there is a hole or another type of opening in the part, there is a block in the cavity to stop the flow of resin. This concept is also used to separate two distinct cavities in the final plastic product.
Air pockets, which are not specific aspects of the product design to produce holes or gaps in the finished item, leak out slowly through little gaps in the plates called vents. While each side of the part is distinct, with a unique shape and specific holes or cavities, the parting line is placed in the best place on the product to simplify the release from the mold. This line is often very evident on household plastic products, along with a hidden little vent hole where the excess air was released.
Ejector pins are another way to remove the final products from the mold. These are usually in the B plate side of the item. Ejector pins are almost always used for any half of the product that moves. These can be spring loaded to essentially pop the bottom half of the mold out of the B plate.
While all this is pretty easy to visualize when you’re thinking about small plastic items like toys, tools, or other household things, there are massive injection molds that produce plastic products so large they need a forklift or crane to maneuver. But, even the largest plastic products use the same basic concept of injection molding we covered here. Only real difference is the size of every component and the amount of plastic resin required in the process.
So, from things as little as a plastic cap for your writing pen to huge wooden planks that are positioned to make docks in a shipyard, injection molds are used to produce all of them. Helps to fuel the motivation to recycle your plastics when you know how understand how vital this waste can be in the production of new things.
If you have a residential swimming pool that has been inundated by stormwater or wastewater or has been neglected and is green with algae, it will be necessary to clean your pool manually. Merely adding chlorine will not be able to clean a pool that is overgrown with green algae. Here are the steps to take to thoroughly clean a swimming pool that is green with algae:
After the above procedure, your pool should be clean, clear, and blue. If the water in your pool is still cloudy, you may need to repeat this process again to thoroughly clean it. Once you have destroyed all the green algae and vacuumed it out of the pool, you can return to a regular maintenance routine and schedule. It is a good idea to use an algaecide once a month (in proportions specified on the bottle) to make sure that all algae has been killed and does not return. With regular maintenance, you can have a blue swimming pool for your family and guests to enjoy. If you don’t feel comfortable cleaning your own pool, visit TigerFlocUS.com for more information.
If you have just been assigned to the task of ordering cartridge heaters for your factory, there are a few things you should know about these heating elements first. Not all cartridge heaters are the same, and to the untrained eye, they look like they are. Knowing how to tell one type of heating cartridge apart from another may mean the difference between igniting the furnace and causing a minor explosion. Here are more things you should know about cartridge heaters and why it is important to know them.
Cartridge Heaters Are Sold in Different Volts and Wattages
Does the furnace or machine in your factory require a cartridge that has twelve volts or one-hundred-twenty volts? The bigger and more powerful the machine, the more likely it will need more voltage to operate. If you purchase a gross of cartridge heaters that are the wrong voltage, not only will you not get the heat or the power that your company’s machinery needs, but you will also have to wait several days more to get the correct cartridges. That may cause multiple production delays or require that you shut down part of the factory because it is not adequately heated for employee comfort and well-being. Likewise, check the wattages on the cartridges that you are currently using and need to replace. Volts and wattages on cartridge heaters vary wildly and are combined to meet all kinds of power requirements.
Cartridge Tubes Are Made of All Kinds of Heat-Conducting Materials
Furnaces and machines that utilize cartridge heaters all need different types because the cartridge tubes are made of different heat-conducting materials. Some are porcelain, which can withstand much hotter temperature requirements because they are forged in kilns at thousand-plus degree temperatures. Others are made from an aluminum alloy that heats up quickly but should only be used in heaters and machines that do not get hotter than the melting point of aluminum. You want the correct cartridge heaters for the job so that the right amount of heat is created but continued heating does not melt, bend or fracture the cartridge tubes.
Most Catridge Heaters Will Need an Electrician for Installation
While you could buy quick-connect cartridge heaters that just snap in and out of their appointed positions, the fact remains that these quick-connect heaters do not come in all of the sizes, voltages, wattages and tube types you may need to order. The ones you do need will more than likely require the skills of an electrician or HVAC contractor to install since they are sold with open-ended wires that need to be cut, stripped, crimped and inserted into their corresponding electrical ports. Even though you have been assigned to purchase the cartridge heaters, it does not mean you need to know how to install them–leave that to the pros.
