Zamac
ZAMAK (or Zamac, formerly trademarked as MAZAK) is a family of alloys with a base metal of zinc and alloying elements of aluminium, magnesium, and copper. Zamak alloys are part of the zinc aluminum, zinc aluminium alloy family; they are distinguished from the other ZA alloys because of their constant 4% aluminium composition. The name ''zamak'' is an acronym of the German language, German names for the metals of which the alloys are composed: (zinc), , and (copper). The New Jersey Zinc Company developed zamak alloys in 1929. The most common zamak alloy is zamak 3. Besides that, zamak 2, zamak 5 and zamak 7 are also commercially used. These alloys are most commonly die cast. Zamak alloys (particularly #3 and #5) are frequently used in the spin casting industry. A large problem with early zinc die casting materials was zinc pest, owing to impurities in the alloys. Zamak avoided this by the use of 99.99% pure zinc metal, produced by New Jersey Zinc Company, New Jersey Zinc's us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chromate Conversion Coating
Chromate conversion coating or alodine coating is a type of conversion coating used to passivate steel, aluminium, zinc, cadmium, copper, silver, titanium, magnesium, and tin alloys. The coating serves as a corrosion inhibitor, as a primer to improve the adherence of paints and adhesives, as a decorative finish, or to preserve electrical conductivity. It also provides some resistance to abrasion and light chemical attack (such as dirty fingers) on soft metals. Chromate conversion coatings are commonly applied to items such as screws, hardware and tools. They usually impart a distinctively iridescent, greenish-yellow color to otherwise white or gray metals. The coating has a complex composition including chromium salts, and a complex structure. The process is sometimes called alodine coating, a term used specifically in reference to the trademarked Alodine process of Henkel Surface Technologies. Process Chromate conversion coatings are usually applied by immersing the part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pot Metal
Pot metal (or monkey metal) is an alloy of low-melting point metals that manufacturers use to make fast, inexpensive castings. The term "pot metal" came about due to the practice at automobile factories in the early 20th century of gathering up non-ferrous metal scraps from the manufacturing processes and melting them in one pot to form into cast products. Small amounts of iron often made it into the castings but never in significant quantity because too much iron would raise the melting point too high for simple casting operations. In stained glass, "pot metal" or pot metal glass refers to glass coloured with metal oxides while it is molten (in a pot), as opposed to other methods of colouring glass in sheet form. Metallurgy There is no metallurgical standard for pot metal. Common metals in pot metal include zinc, lead, copper, tin, magnesium, aluminium, iron, and cadmium. The primary advantage of pot metal is that it is quick and easy to cast. Because of its low melting temperat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hi-Point Firearms
Hi-Point Firearms, also known as Strassell's Machine, Inc (distributed by MKS Supply), is an American firearms manufacturer based in Mansfield, Ohio. All of their firearms are manufactured in several different locations in Ohio. Construction of products Pistols Hi-Point semi-automatic pistols are polymer framed handguns based on the blowback design. Different from other blowback design pistols such as the Walther PPK, the P-64, and the Astra 600 which use a heavy slide combined with a stiff recoil spring to hold the breech closed, these pistols use a heavier slide so they can use a softer recoil spring. When compared to breech-locking handguns of the same caliber and dimensions, the Hi-Point is rather top heavy. As with most blowback handguns, this pistol has fewer moving parts to clean and lubricate than its locked breech counterparts. While most semi-automatic pistols can be field stripped without the use of any tools, Hi-Point pistols require a small punch or a screwdriv ...

Smith & Wesson SD
The Smith & Wesson Sigma, was Smith & Wesson's first venture into using synthetic materials in pistol construction, using high-strength polymer material for the frame. The pistol is similar to a Glock safe-action pistol in both its design and operation, leading to controversy and speculation regarding the pistol's patents' legality. Description Created in 1994, the Sigma incorporates a pre-set striker firing mechanism. It is available in both .40 S&W cartridge and 9×19mm Parabellum, being one of the first pistols purpose-designed to handle the .40 S&W. Similarly styled sub-compact designs in .380 ACP and 9×19mm were also produced. A limited number of these pistols were also chambered in .357 SIG. Material used for the slide is zinc-aluminium alloy known as ZAMAK. Patent issue The Sigma series pistols were so similar to the competing Glock pistols that Glock sued Smith & Wesson for patent infringement. The case was settled out of court in 1997, with S&W agreeing to make altera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Facto Standard
A ''de facto'' standard is a custom or convention that has achieved a dominant position by public acceptance or market forces (for example, by early entrance to the market). is a Latin phrase (literally " in fact"), here meaning "in practice but not necessarily ordained by law" or "in practice or actuality, but not officially established". The term ''de facto'' standard is used in contrast with standards defined by organizations or set out in law (also known as ''de jure'' standards), or to express the dominant voluntary standard when there is more than one standard available for the same use. In social sciences a voluntary standard that is also a ''de facto'' standard is a typical solution to a coordination problem. The choice of a ''de facto'' standard tends to be stable in situations in which all parties can realize mutual gains, but only by making mutually consistent decisions. In contrast, an enforced de jure standard is a solution to the prisoner's problem. Examples ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange Peel (effect)
Orange peel is a certain kind of finish that may develop on painted and cast surfaces. The texture resembles the surface of the skin of an orange, hence the name "orange peel". Gloss paint sprayed on a smooth surface (such as the body of a car) should also dry into a smooth surface. However, various factors can cause it to dry into a bumpy surface. This is typically the result of improper painting technique, and is caused by the quick evaporation of thinner, incorrect spray gun setup (e.g., low air pressure or incorrect nozzle), spraying the paint at an angle other than perpendicular, or applying excessive paint. Such a texture can be smoothed out with ultra-fine sandpaper, but it can be prevented altogether by changing the painting technique or the materials used. In some situations, such as interior house paint, the orange peel texture is desirable. In this case, a texture paint is generally applied with a spray gun. The texture is then painted over with the appropriate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Injection Molding
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers that ...

Die (manufacturing)
A die is a specialized machine tool used in manufacturing industries to cut and/or form material to a desired shape or profile. Stamping dies are used with a press, as opposed to drawing dies (used in the manufacture of wire) and casting dies (used in molding) which are not. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology. Continuous-feed laser cutting may displace the analogous die-based process in the automotive industry, among others. Die stamping Blanking and piercing are two die cutting operations, and bending is an example of a die forming operation. Die forming Forming operations work by deforming materials like sheet metal or plastic using force (compression, tension, or both) and rely on the material's mechanical properties. Forming dies are typically made by tool and die makers and put into production after mounting into a press. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
