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.
The whole process is controlled by the item manager and after every step the process will be inspected. Anything that does not look right will result in the whole process starting from the beginning. The machines that are normally used are a drilling as well as a grinding machine.
Later another material was made and was called Celluliod. These were created from using compounds produced that reacted to nitric and sulfuric acids as well as a strong smelling compound known today as camphor. Dyes and other agents were also added.
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.
The material then enters the grooves of the screw and is pushed towards the mold as the screw rotates. The molten is injected quickly through a nozzle at the end of the barrel by pressure that has been building up. This pressure lets the material be packed and held in the mold.
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.
