    People have been fascinated by metal fabrication for centuries. And from its beginnings in the seventh century B.C. to today, there have been massive innovations in the development of  metal stamping .   Metal Stamping History The first attempts at metal stamping were made on coins. Researchers believe that the first coins were created in the seventh century B.C. by the Lydians, people living in what is now present-day Turkey. To stamp the coins, the Lydians created a die and carved the metal with a heavy hammer. The coins were typically made from gold and silver.   This simple process remained largely unchanged until 1550 when a German silversmith named Marx Schwab created a screw process to stamp coins. As many as 12 men were needed to turn the screw press to give it enough pressure to form the metal.   During the industrial revolution, the manual screw turning process was replaced by steam power to drop a heavy weight on the die to stamp the desired ...

    Numerous factors influence the total cost of a finished casting, ranging from design to type of metal to the type of price quotation. Efficient purchasing of  iron castings  requires using a considerable amount of specialized information. With the generally increased emphasis on value analysis techniques, purchasing managers must evaluate the many important factors that directly influence the total cost of a component part. These are usually grouped under the general headings of quality, service, price and delivery. The relative importance of these considerations will be determined by each buyer. The agent must establish his or her own weighting system of these factors, based on the particular circumstances.   1. Casting Design Size, weight and complexity of a casting are generally the most important cost factors because they directly influence the materials and labor required for its production. Weight of the metal in a casting is also important, but it no ...

When deciding on a gate you need to consider many factors- opening size, security level, whether it should be horizontal slide , swing or vertical lift and even the material of the gate itself- aluminum or steel.   ❓  So, what is the difference between an aluminium and a steel gate ? ❓  Which is the best choice for your application ?   Aluminium Gates Aluminium Gate While aluminium has become popular for gates and fence due to its corrosion resistance and weight, steel is a stronger alternative. Aluminium is a lightweight, durable, and versatile material. It's not susceptible to corrosion, so aluminium fencing and gates will look great for years despite being exposed to the elements. The drawback to aluminium is that it can be easily bent, so it's not as effective for fencing and gates in premises that require tough barriers or security, such as industrial or commercial settings. It is best used for aesthetic purposes, such as residential garden, yard or pool fencing...

  Here's how the same  cast iron fireplace  tools have been refurbished twice and look as good as new.   You'll need: Chainmail Scrubber Lard Oil 1. Scrub the Rust When you're trying to restore a cast iron poker set, the first step of the process is to remove the rust. I treat this the same way I do with restoring cast iron pans. I begin by taking each piece and running it under hot water. I'll use chainmail to scrub the rusty spots on the poker set. Don't use soap on cast iron, only water. You can also throw the cast iron fireplace tools into a fire which is burning extremely hot. However, don't throw the broom in the fire because the fibers which make the broom will burn off. My preference is to scrub the rust with chainmail because it's feasible regardless of the time of year or the weather. If you decide to burn the cast iron to remove the dirt and rust, use extreme caution when handling the fire and also when handling the set which have been left to bur...
