There is a common method of manufacturing parts that are replicated at high volumes. Injection molding is used in the making of things like bottle caps, pocket combs, one-piece chairs and small tables. Certain storage containers and any other plastic product that is available in shops, all fall under this way of manufacturing.
The manufacturer that is termed the town of the plastic molds is based in Haungyan city. Their products are exported all over the world and are reputed to have excellent sales service. Once the customer has placed an order they will then make a sample of the requirements.
In 1861 the first marketable plastic was made by Alexander Parkes. He named these different materials after himself and in 1862 he gave a show at the International Exhibition in London describing what they could be transformed into. There was a major drawback once these materials were heated and put through the mold and allowed to cool, it was that they seemed to come out very dry and had a tendency to crack.
The injection unit is responsible for heating and injecting materials into the mold. The first part is called the hopper and this is a container where the raw plastic is added. This will have a bottom that is able to open where it can then feed the materials into the barrel.
The whole cycle is very short normally between two seconds to two minutes and consists of four stages. Before the material is injected into the mold it needs to be very securely closed by a clamping unit. Each mould it attached to the molding machine and the top half is allowed to move.
In 1872 John Hyatt and his brother were given the exclusive right to market the first injection machine, these were much simpler then the ones of today. It was very much like a large syringe using a plunger to introduce the plastic through a tube that was heated into a mold. It took a long time for this kind of industry to catch on but is now what produces our everyday products.
During the Second World War this industry expanded drastically as there was a huge demand for inexpensive and mass produced products. In the middle 1900s the first screw injection machine was made and this one allowed more control over the quickness and superiority of articles produced. The gas assisted process then came about and this permitted a more complex production of hollow articles.
After a certain amount of time the cooled part can be removed by the ejection system which is attached to the back end of the mold. It is then opened with a certain amount of force. This kind of molding is a quick and effective way of producing objects that are too be used frequently.
