Scale model kit

A plastic model kit, (plamo in Eastern influenced parlance), is a consumer grade plastic scale model manufactured as a kit, primarily assembled by hobbyists, and intended primarily for display. A plastic model kit depicts various subjects, ranging from real life military and civilian vehicles to characters and machinery from original kit lines and pop fiction, especially from eastern pop culture. A kit varies in difficulty, ranging from a "snap together" model that assembles straight from the box, to a kit that requires special tools, paints, and plastic cements.

The most popular subjects of plastic models by far are vehicles such as aircraft, ships, automobiles, and armored vehicles such as tanks. The majority of models throughout its early history depict military vehicles, due to the wider variety of form and historical context compared to civilian vehicles. Other subjects include science fiction vehicles and mecha, real spacecraft, buildings, animals, human(oid) dolls/action figures, and characters from pop culture. While military, ship, and aircraft modelers prize accuracy above all, modelers of automobiles and science fiction themes may attempt to duplicate an existing subject, or may depict a completely imaginary subject. The creation of custom automobile models is related to the creation of actual custom cars and often an individual may have an interest in both, although the cost of customizing a real car is obviously enormously greater than that of customizing a model.

The first plastic models were injection molded in cellulose acetate (e. g. Frog Penguin and Varney Trains), but currently most plastic models are injection molded in polystyrene, and the parts are bonded together, usually with a plastic solvent based adhesive, although experienced modelers may also use epoxy, cyanoacrylate, and white glue where their particular properties would be advantageous. While often omitted by novice modellers, specially formulated paint is sold for application to plastic models. Complex markings such as aircraft insignia or automobile body decorative details and model identification badges are typically provided with kits as screen printed water slide decals. Recently, models requiring less skill, time, and/or effort have been marketed, targeted to younger or less skilled modelers as well as those who just wish to reduce the time and effort required to complete a model. One such trend has been to offer a fully detailed kit requiring normal assembly and gluing, but eliminate the often frustrating task of painting the kit by molding it out of colored plastic, or by supplying it pre painted and with decals applied. Often these kits are identical to another kit supplied in normal white or gray plastic except for the colored plastic or the prepainting, thus eliminating the large expense of creating another set of molds. Another trend which has become very extensive is to produce kits where the parts snap together, with no glue needed; sometimes the majority of the parts snap together with a few requiring glue. Often there is some simplification of detail as well; for instance, automotive kits without opening hoods and no engine detail, or sometimes opaque windows with no interior detail. These are often supplied in colored plastic, although smaller details would still require painting. Decals are usually not supplied with these but sometimes vinyl stickers are provided for insignia and similar details. Resin casting and vacuum forming are also used to produce models, or particular parts where the scale of production is not such as to support the investment required for injection molding. Plastic ship model kits typically provide thread in several sizes and colors for the rigging. Automobile kits typically contain vinyl tires, although sometimes these are molded from polystyrene as well, particularly in very inexpensive kits. Thin metal details produced by photoetching have become popular relatively recently, both as detailing parts manufactured and sold by small businesses, and as parts of a complete kit. Detail parts of other materials are sometimes included in kits or sold separately, such as metal tubing to simulate exhaust systems, or vinyl tubing to simulate hoses or wiring.

The first plastic models were manufactured at the end of 1936 by Frog in the UK, with a range of 1/72nd scale model kits called 'Penguin'. In the late 1940s several American companies such as Hawk, Varney, Empire, Renwal and Lindberg began to produce plastic models. Many manufacturers began production in the 1950s and gained ascendancy in the 1960s such as Aurora, Revell, AMT, and Monogram in America, Airfix in UK and Heller SA in France. Other manufacturers included; Matchbox (UK), Italeri, ESCI, (both Italian) Novo {ex Frog moulds} (former Soviet Union), and Fujimi, Nichimo and Bandai (Japan). American model companies who had been producing assembled promotional scale models of new automobiles each year for automobile dealers found a lucrative side business selling the unassembled parts of these "promos" to hobbyists to assemble, thus finding a new revenue stream for the injection molds which were so expensive to update each year. These early models were typically lower in detail than currently standard, with non opening hoods and no engines, and simplified or no detail on the chassis, which attached to the body with very visible screws. Within a short time, the kit business began to overshadow the production of promos, and the level of accuracy and detail was raised to satisfy the demands of the marketplace. In the 1960s, Tamiya manufactured aircraft kits in the peculiar (at the time) scale of 1/100. Although the range included famous aircraft such as the Boeing B 52 Stratofortress, McDonnell Douglas F 4 Phantom II, North American F 86 Sabre, Dassault Mirage III, Grumman A 6 Intruder and the LTV A 7 Corsair II, it never enjoyed the same success as 1/72 scale kits did. Soon, Tamiya stopped manufacturing 1/100 scale aircraft but re issued a small selection of them in 2004. Since the 1970s, Japanese firms such as Hasegawa and Tamiya, and since the 1990s also Chinese firms such as DML, AFV Club and Trumpeter have dominated the field and represent the highest level of technology. Brands from Russia, Central Europe, and Korea have also become prominent recently with companies like Academy Plastic Model. Many smaller companies have also produced plastic models, both in the past and currently. Prior to the rise of plastic models, shaped wood models were offered to model builders. These wood model kits often required extensive work to create results easily obtained by the plastic models. With the development of new technologies, modeling hobby can also be practiced in the virtual world. The Model Builder game, produced by Moonlit studio, available on Steam (service), consists of cutting, assembling, and painting airplanes, helicopters, tanks, cars, and others and making dioramas with them. Transferring the hobby to the game world allows novice modelers and people who do not have space, time, or money to buy multiple models to pursue their interests.

While injection molding is the predominant manufacturing process for plastic models, the high costs of equipment and making molds make it unsuitable for lower yield production. Thus, models of minor and obscure subjects are often manufactured using alternative processes. Vacuum forming is popular for aircraft models, though assembly is more difficult than for injection molded kits. Early manufacturers of vacuum formed model kits included Airmodel (the former DDR), Contrail, Airframe (Canada), Formaplane, and Rareplanes (UK). Resin casting, popular with smaller manufacturers, particularly aftermarket firms (but also producers of full kits), yields a greater degree of detail moulded in situ, but as the moulds used don't last as long, the price of such kits is considerably higher. In recent times, the latest releases from major manufacturers offer unprecedented detail that is a match for the finest resin kits, often including high quality mixed media (photo etched brass, turned aluminum) parts.

Many modellers build dioramas as landscaped scenes built around one or more models. They are most common for military vehicles such as tanks, but airfield scenes and 2 3 ships in formation are also popular. Conversions use a kit as a starting point, and modify it to be something else. For instance, kits of the USS Constitution ("Old Ironsides") are readily available, but the Constitution was just one of six sister ships, and an ambitious modeller will modify the kit, by sawing, filing, adding pieces, and so forth, to make a model of one of the others. Scratch building is the creation of a model "from scratch" rather than a manufactured kit. True scratchbuilt models consist of parts made by hand and do not incorporate parts from other kits. These are rare. When parts from other kits are included, the art is technically called "Kit Bashing." Most pieces referred to as "scratchbuilt" are actually a combination of kit bashing and scratchbuilding. Thus, it has become common for either term to be used loosely to refer to these more common hybrid models. Kitbashing is a modelling technique where parts from multiple model kits are combined to create a novel model form. For example, the effects crews on the various Star Trek TV shows frequently kitbashed multiple starship models to quickly create new classes of ship for use in background scenes where details would not be particularly obvious.
