Container Exchanger Evaluates Metal Bins Versus Gaylord Boxes
There are many benefits of metal bins including durability and reusability; some are collapsible making return shipments more cost effective. Some metal bins are very heavy-duty, so they can hold a lot of heavy product, like casted or machined metal parts. This product can then be stacked and stored in a relatively small space. Wire baskets are effective because they are affordable. Container Exchanger (www.containerexchanger.com) is dedicated to the sale and resale of reusable packaging and containers. The firm resells folding bulk containers, metal storage bins, plastic industrial totes, plastic pallets, and used gaylord boxes nationwide. When a company is finished using a returnable packaging fleet, Container Exchanger represents the seller and finds a buyer for the used bulk packaging. Sellers enjoy a high sales price for a better return on investment. Buyers save significantly in comparison to new packaging prices.
Dave Madden, President of Container Exchanger recently discussed the efficacy of reusable metal containers, noting that, “Automotive molders, automotive components, durable goods manufacturers, metal stamping, metal casting… really absolutely any industrial company that must store or ship intermediate product all benefit from reusable metal containers. In other words, you have sub-assemblies or large parts that are transported to an “internal” customer (a different part of the plant).” Madden provided several example such as the casted transmission housing gets put in a metal bin and is taken to machining and assembly line, or sub-assemblies that are transported to an external company en-masse.
“A light-duty wire basket is pretty cheap for the internal storage volume and they are often used to hold cardboard for recycling or transporting and storing light stamped parts or molded parts,” suggested Madden.
Price savings of Used Reusable metal bins are significant; used metal bins are often 30% – 50% of the cost of new (70% off the new cost). The only expendable bulk solution is a Gaylord box. These boxes sell for $20 each for a good box and one has to buy a pallet. A wire basket might run $80 used. Gaylord boxes might last 4 uses or so, whereas the wire basket would last 200+ (both estimates and depend on usage). The payback comes after only 13 uses. And if the basket lasted only 200 uses, there would be a savings of 1500% compared to using a Gaylord box.

Essential Jewellery Making Tools For Beginners
Like any other craft, jewellery making has a list of essential tools that will make your hobby much more enjoyable and your results much more professional. For the beginner it can be confusing as the huge selection of tools available range from the basic to the specialist. However, there are certain jewellery making tools that should have a place in everyone’s studio.
The first thing to look at is your surroundings. Tools don’t just include pliers and cutters – the definition also incorporates things such as adequate lighting, a suitable working area and good storage facilities. Ask any jewellery maker or craftsperson which is the most essential tool of all and they will all tell you the same thing: good lighting. Without adequate lighting you will find it harder to do fine work and you risk straining your eyes. If you have directional lighting make sure that it doesn’t come from behind you, as you will end up casting your own shadow across your work, making it difficult to see fine details.
Once you start making jewellery you will be surprised how quickly you start to accumulate equipment, so apart from having a good working area make sure you have plenty of storage facilities. Findings or bead storage boxes are ideal. They’re strong and compartmentalised, meaning there are plenty of separate sections to keep findings and beads stored safely.
There are three basic types of pliers used for jewellery making; round nose, snipe nose and crimping pliers. Round nose pliers (also known as rosary pliers) have rounded jaws that taper to a point. They are used for bending wire and for making loops, coils and spirals. Snipe nose pliers are semi-round with the inside of the jaws being flat. They are used for bending and wrapping wire, making loops and opening and closing jump rings. Crimping pliers have specially notched jaws that are used to fold and crimp metal crimp beads.
Wire cutters, preferably flushing cutting, are essential for making clean, precise cuts on wire, beading wire, eyepins and headpins. It may be tempting to use a pair of ordinary wire cutters to try and save money, but jewellery wire cutters are designed specifically for use with the different types of wire used in jewellery making. A pair of good wire cutters is an investment that will keep their sharp cutting edge for far longer than a cheaper alternative.
Because you are using tools, safety must be a consideration. A good pair of safety glasses is a wise investment and although you won’t need them for simple projects such as stringing beads, cutting wire can produce small chips that can damage the eyes very easily. You will also need to consider other safety measures if you are using glues and adhesives, so ensure that your working area is well ventilated. If you are using any heat (such as kilns or gas burners) then ensure that your jewellery making equipment includes a heatproof surface to stand hot objects on.
Finding a good supplier is your next task. There are plenty of jewellery equipment suppliers, so the first thing is to find one that has a reputation not just for supplying the hobby market, but for supplying the professionals as well. You can be certain that the equipment they supply will be of the highest standard. It is a case of paying for quality, but the bare essentials such as the three basic pliers and a pair of wire cutters will give you a good starting point. From then you can add equipment as you go along, including magnifying work lights, speciality pliers, reamers and, of course, plenty of books on jewellery making!

The Zinc-aluminium Die Casting Alloys
The zinc-aluminium die casting alloys
New high performing zinc-aluminium ZA casting alloys (zA-8, ZA-12, ZA-27) give superior mechanical properties which designers can apply utilizing die casting technology. In general the ZA alloys are stronger, harder and offer more creep resistance than standard zinc alloys and can be used where bearing properties are important.
Aluminium alloys with 0.5-0.9% Fe content have largely replaced 1350 EC alloy for making electrical circuits because the latter continuously suffered from gradual loosening at terminals, which led to overheating. This problem has been totally removed in new conductor alloys without sacrifice of conductivity.
To get economic benefit of weight advantage of aluminium wire should be capable of attaching securely to standard fixtures without special handling techniques. But EC wire on binding screw terminals tightened to a standard torque may become loose, when the wire heats due to being overloaded. The wire gets expanded more than the Cu-alloy fixture and creeps to relax the added stress.
On getting cool it contracts to a smaller dimension, whereby the area of contact is reduced and it permits oxide to form at interface. On a subsequent current overflow, the overheating increases which leads to further loosening of wire. EC wire annealed for adequate bend ability gets sub structurally loosened at 200°C and ultimately fails due to repetitions of these cycles.
The new alloys (800 series) of 0.5-0.9% Fe have much better microstructural stability and creep resistance and, therefore, they are not prone to these failures.
While annealed to the same ductility or bend ability, the high Fe alloys are double strong. This capability has been established by practical field use of many years in USA, Europe and South Africa after these alloys were introduced in 1968.
Better and latest alloys which not only provide high integrity to terminations but are suitable for magnet wire after normal hot annealing have been made after adding a third alloy to improve its performance examples are 0.5% Fe with 0.5% Co and 0.5% Fe with 0.2-0.4% Si.
Processing and microstructure:
In continuous casting a bar of 50cm2 is made at 16 m/min on a 2.5m diameter copper wheel. The quick solidification results in a 20 μm dendrite arm spacing and eutectic red cpacing of about 0.2 μm with a supersaturation of about 0.1% Fe. These very fine particles play a significant role in giving stability to substructure while being incapable of nucleating crystallization.
The presence of sub grains has been known in hot worked aluminiums but without quantitative determinations of the dimensions or the effects on properties. As the temperature rises from 200-450°C, the cold yield strength of the hot worked product decreases greatly from the strengthening made by 97.5% cold rolling.
As has been seen in many hot worked metals, the yield strength is inversely proportional to sub grain diameter. Because the temperature is less and strain rate is high in a given pass than those in the previous one, substructure “inherited” from i.e., carried forward from, the latter is altered by dislocations to the existing walls to raise their density and by formation of new walls to subdivide the sub grains lessening their size.
