Die Cast Model

What is a Die Cast Model? Die Cast (or Diecast, or Die-cast) is a term that refers to collectible models or toys produced by using the die casting method. Diecast models were first produced early in the 20th century. The models are made of metal, with plastic, rubber, or glass details. Wholly plastic models are made by a similar process of injection moulding, but the two are rarely confused. The metal used is either a lead alloy, or more commonly Zamak, an alloy of zinc with small quantities of aluminium and copper. Lead, as previously so widely used for cast metal toys, or iron are impurities that must be carefully avoided in this alloy, as they give rise to zinc pest. These alloys are also referred to casually as white metal or pot metal, although these terms are also confused with the lead model alloys. The most common die-cast toys are automobile scale models, aircraft, construction equipment, and trains, although almost anything can be produced by this method.


The first diecast models on the market were basic, consisting of a small car or van body with no interior. In the early days it was common for impurities in the alloy to result in zinc pest; the casting would distort or crack for no apparent reason. As a result, diecast models made before World War II are difficult to find in good condition. The later high-purity Zamak alloy avoided this problem.


Lesney began making diecast toys in 1947. Their popular Matchbox 1-75 series was so named because there were always 75 different vehicles in the line, each packaged in a small box designed to look like those used for matches. These toys became so popular that "Matchbox" was widely used as a generic term for any diecast model car, regardless of who the actual manufacturer was.


The popularity of diecast toys as collectibles developed in the 1950s, as their detail and quality increased. Consequently, more companies entered the field, including the Corgi brand, produced by Mettoy, which appeared in 1956 and pioneered the use of interiors in their models.


In 1968, Hot Wheels were introduced in the United States by Mattel, to address the complaint that they had no line of toys for boys to balance their line of Barbie dolls for girls. Because they looked fast and were fast, Hot Wheels quickly gained an important niche in the diecast toy market, becoming one of the world's top sellers and challenging the Matchbox 1-75 series in popularity.


During the 1960s various companies began to use diecast vehicles as promotional items for advertising. The idea that children can play a large part in a family's decision as to what products to buy came into wide circulation. In addition, by the 1980s it was apparent that many diecast vehicles were being purchased by adults as collectibles, not as toys for children. Companies such as McDonald's, Sears Roebuck, Kodak, and Texaco commissioned toymakers to produce promotional models featuring their names and logos, or licensed their use. One early example was an American Airlines London bus produced by Matchbox, an idea some other airlines quickly copied.


Beginning in the mid '70s trucks and other commercial vehicles took a lion's share of the diecast market. Matchbox started the trend when they re-launched their Models of Yesteryear range. They made a score of different versions of their Y-12 Ford Model T van, along with other trucks in colorful liveries such as Coca-Cola, Colman's Mustard, and Cerebos Salt. They also made promotional versions for Smith's Crisps and Harrods department store. Some models were made exclusively for certain markets and immediately became quite expensive elsewhere: Arnott's Biscuits and Sunlight Seife are examples.


Corgi copied this idea when they expanded the Corgi Classics line in the mid-'80s, producing more than 50 versions of a 1920s era Thornycroft van. Some collectors disparaged this development as "collecting paint," as the castings were identical; only the decorations were different. Other collectors created what they called the "10-Foot Rule" when the collecting of minor variations of the same vehicle got out of hand. The idea was that, if you couldn't differentiate between two versions of a model from 10 feet away, it wasn't worthwhile to collect both of them.


In the seventies, Japanese toymaker Popy created a line of die-cast toys based on the popular Super Robot anime series of the period. The line was named Chogokin, meaning "Super Alloy", after the futuristic metal robot Mazinger Z was said to be made of. The line was meant to give kids a sense of the weight of the super robots in the cartoons, in a similar manner to Popy's other line, Jumbo Machinder, and the name gave the children the idea that their toys were made of the same stuff as the "real" robots. The line proved popular, with some figures imported to the west. In the late nineties, Bandai created the Soul of Chogokin line of adult collector figures featuring metal parts, as a callback to the original Chogokin toys, and then the smaller but similar Super Robot Chogokin line.


Despite their popularity, many diecast manufacturers went belly-up in the 1980s. Meccano, Matchbox, and Corgi all went bankrupt within a three-year span, which essentially reflected the economic climate in the UK at that time. It had become virtually impossible to manufacture in England and compete on the world market. Matchbox was purchased by a Hong Kong conglomerate named Universal Holdings, which moved production from England to Macau. Later, Mattel bought Matchbox, essentially making Hot Wheels and the Matchbox 1-75 line sister brands. The two brands continue to sell under their own separate names.


Meanwhile, Corgi had been acquired by Mattel, which moved the office from Swansea, Wales to Leicester, England, and moved manufacturing to China. A new company called Oxford Diecast acquired the former Corgi factory in Swansea and commenced manufacture for themselves and Corgi. Matchbox also bought the Dinky Toys name, long after the Liverpool factory was closed. Manufacturing resumed in China. In a series of subsequent shifts, a group of Corgi executives bought back the Corgi Classics line from Mattel, and portions of the Matchbox line were sold to an Australian company named Tyco.


Effectively from the ashes of Matchbox's bankruptcy arose Lledo, a company created by former Matchbox partner Jack Odell. Odell believed that British collectibles for British collectors could still be profitably produced in England. Lledo took over part of the Matchbox factory in Enfield, and introduced their "Models of Days Gone" line of diecast vehicles in 1983. The first series of Days Gone models included re-makes of some of the most popular and respected first and second-generation Matchbox Models of Yesteryear. Lledo models were very popular collectibles in the '80s, leading to a period of diversification, but by the '90s they were eclipsed by other brands, and by 2002 Lledo went broke. Parts of their line were purchased by Corgi, which moved production to China.


Oxford Diecast developed a range of promotional stylised vehicles and maintained its manufacturing base in Swansea until 2000 when it relocated its production to a plant it owned in China. As such is was the last large scale producer of diecast models to manufacture in the UK, although it choose to own and build its own Chinese factory rather than outsource production entirely.


In addition to trucks, Corgi produced hundreds of versions of their 1/64 scale Routemaster bus in the '80s and '90s. Like other collecting and promotional model trends, it started as a trickle and soon became a flood. Many versions were made to be sold exclusively in the stores whose advertising appeared on the buses. Harrods, Selfridges, Gamley's, Hamley's, Army & Navy, Underwood's, and Beatties were among the British stores employing this idea. A South African chain called Dion was one of the few overseas firms to follow suit.


Then 1/76 scale buses became very popular in Britain in the late '80s and early '90s, with competing lines from Corgi and Gilbow Holdings fighting for the market. The 1/76 scale fits in with British 'OO' scale model trains.


By the 1990s NASCAR enjoyed increasing popularity in the USA, and a large number of racing-related Nascar diecast cars and trucks, painted in the colors of the different racing teams, appeared from various manufacturers. Racing Champions was a leading brand of such models, but there were many others. In addition to cars, trucks, buses, agricultural implements, and construction equipment, diecast aircraft and military models were popular. While Dinky had made such models decades earlier.


Popular Diecast Model Scales



  • 1/12 scale - Very large, highly detailed models; usually about 14 or 15 in (36 or 38 cm) long; mainly targeted at adult collectors. These models are generally much more expensive than the 1/18 models. Many diecast motorcycles are also produced in this scale.

  • 1/18 scale - Large, detailed models, usually about 7 or 8 in (18 or 20 cm) long; mostly targeted at adults. America is the main market for these, although some European and Australian companies also produce cars and even trucks in this scale.

  • 1/24 scale - This has long been a favoured scale in the USA, due to many construction kits and dealer promotional models being this size. Mebetoys of Italy had a large range of cheap 1/24 model cars. Franklin Mint and Trax also use this scale.

  • 1/32 scale - Intermediate size, most common for model tractors and other agricultural vehicles; Britains has used this scale for decades, and it is also used by Ertl and Siku. Vintage car models are also quite common in 1/32 scale.

  • 1/36 scale - Popularized by Corgi in the 1970s, a common scale for toy vehicles such as those from Maisto, Kinsmart and Welly

  • 1/34 scale - Used almost exclusively by First Gear Models of the USA for their large scale diecast trucks.

  • 1/43 scale - the most popular scale for model cars worldwide. This scale was made popular by Dinky in the 1930s as it was compatible with O gauge model railways. This scale is the most commonly used in Britain, Europe, Japan and Australia, but less so in the USA. In continental Europe 1/43 is often favoured for model trucks. It is also widely used for handbuilt models in resin and white metal.

  • 1/48 scale - Several companies produce diecast model aircraft in 1/48 scale, which is a popular scale for plastic construction kits. Some diecast military vehicles and model train accessories are also made in this scale.

  • 1/50 scale - The most widely used scale for trucks, buses and especially construction vehicles.

  • 1/55 scale - used mostly by Siku of Germany for its toy range of cars and trucks. The Disney-Pixar Cars Die-Cast Line by Mattel are nominally in this scale.

  • 1/60 scale - the scale of the immensely popular pre- and post-war military vehicles series by Dinky Toys, and still used by many military modellers.

  • 1/64 scale - popular for farm models and American model trucks. Matchbox, Hot Wheels, Johnny Lightning and model Nascar racers are nominally this size. However, in recent years, Japanese companies like Kyosho, Aoshima and CM's Corp have been producing ranges of highly-detailed 1/64 models, including racing cars and road cars, with CM's Corp mainly producing 1/64 rally model cars.

  • 1/72 scale - usually used for military die-cast armoured fighting vehicles due to compatibility with 1/72 plastic construction kits.

  • 1/76 scale - scale popular mainly in Britain, Australia and Hong Kong for highly detailed buses and lorries such as those by EFE and Corgi OOC, and Trax Models in Australia. A major growth in this scale was caused when Oxford Diecast entered the market with a range of over 90 different cars and commercial vehicles. These models were originally intended as OO scale model railway accessories, but became collectibles in their own right.

  • 1/87 scale - These are compatible with H0 scale model trains, and tend to be more popular in the USA and continental Europe. They are more commonly made of plastic, and German companies such as Herpa and Wiking produce wide ranges of highly-detailed models in this scale.

  • 1/148 scale - compatible with British N scale model trains, this scale has recently gained popularity in the UK due to its compact size and low priced models from Oxford Diecast.
