    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...

  Aluminum Casting Fence  Across all of the manufacturing, the question “Which  aluminum casting method  should I use?” can only be solved by asking and answering further questions about the application at hand, the requirements of the project overall, and your needs as a customer. This is as true for aluminum casting methods as it is for any other process. The benefits and applications of using aluminum casting techniques for a project are vast, but there are several further choices to consider when deciding how to cast aluminum parts for your application. In this piece, we'll quickly summarize the differences between the available methods, and provide an easy guide to help you determine the right choice.   Aluminum Casting Methods: The Three Processes Three primary metal casting methods can be used to cast aluminum: die casting, permanent mold casting, and sand casting. The methodology behind each of these metal casting techniques is as follows: Sand casting: ...

    Cast Iron fireplaces  are more often than not associated with either the ostentatious, very ornate early Victorian Gothic revival period or the later more subdued architectural influences of the late Victorian and Edwardian period. Late Victorian and Edwardian style fireplaces are characterised by their elongated contemporary linear lines of their design heavily influenced by the work of the Arts and Crafts movement and the then contemporary alternative of curvier stylised flowers, stems and buds, and elegant lines epitomised by the Art Deco and Art–Nouveau design period. Original and reproduction cast iron fireplaces of this period are identifiable by their cast iron hoods raised geometrically sinuous flowers, or elegant sweeping lines, and tile inserts, reflecting a continuous, upwards, and organic movement and growth of natural forms of birds, butterflies dragon flies, flowers, foliage, and even the sun.   The popularisation of the cast-iron fireplace not only...

  The most important consideration in  aluminium casting  is the production volume. With the right casting method, your products will be of desired quality in terms of dimensional accuracy, surface quality, thermal and electrical conductivity, mechanical strength, costs of production and tooling, as well as delivery time. However, the annual production volume that can be made with each method is dependent on the requirements and the budget for your product – the production volumes mentioned here are rough estimates.   Small-volume production and prototyping Aluminium Sand casting is a method for low production volumes (1 to 5,000 units per year) as well as prototyping. In this method, molten aluminium is poured into a resin-bonded sand mould to produce castings of all sizes with low tooling costs. On one hand, depending on the type of product, this method might be the fastest method for casting it. On the other hand, the delivery time might be too long to respond to ...
