Plastics are an integral part of our daily life. We are surrounded by plastic at home, in the office and everywhere in between. Whether it is jars or bottles in the kitchen, chairs and computer keyboards in the office or hubcaps on your car wheels, plastic seems omnipresent. There are 2 basic kinds of Plastics, namely thermoplastics and thermosetting plastic materials, depending on the polymers which are used to make it. The differences between the two kinds are that the former becomes pliable at high temperatures and sets when cooled, while the latter sets permanently. There are many ways of moulding plastic, like Extrusion moulding, Rotation moulding, Blow moulding, Compression moulding, Injection moulding, etc. Injection moulding can be used as a manufacturing process for both thermoplastic as well as thermosetting plastics.
The process is roughly as follows:
1. A product is designed by an engineer or industrial designer.
2. A mould-maker or tool maker prepares a mould from metal, usually steel or aluminum.
3. Material is fed into a heated barrel, mixed and then forced into the mould cavity where it cools and hardens into the shape of the cavity. Plastic Injection moulding is used in the manufacture of a wide range of parts right from paper clips to the bodies or panels of cars. It is ideal for manufacturing large volumes of an object and is the most commonly used method for parts manufacturing. Approximately 30% of all plastic products are made using the Injection moulding process. The advantages of this process are:
• High production rates
• Repeatable high tolerances
• The ability to use a wide range of materials
• Low labour cost
• Minimal scrap losses
• Little or no need to finish parts after moulding.
Some disadvantages of this process are:
• Expensive equipment investment
• Potentially high running costs
• The need to design moldable parts.
One of the most important tools in the moulding process is the injection mould itself. They are made using highly advanced technology. Since making a mould is not child’s play, it is not feasible for small businesses to invest in mould-making for themselves. The solution for them lies in outsourcing their requirements to companies that specialize in mould-making. These mould manufacturers will make a mould to the exact requirements specified, which the buyers can use to mass-produce toys, utensils, cell phone covers, bottle caps, or anything else that they want to. Or the mould-making company might make a mock mould to the exact specifications, execute the manufacturing process and present the ready-to-use part to their customer. The process of mould making is very intensive and requires highly skilled professionals to ensure that the mould is created perfectly. Only if the mould is perfect will the end-product be of the required high standards. These moulds are created using high precision tools and instruments, generally based on a 3D computer generated model, which is based on a blueprint provided. The process of making moulds is nowadays highly automated due to the high degree of precision required. If you are looking for high precision injection moulds, log on to: www.mould.co.kr.

Great Information Keonwoo, I was really not aware of all these things about plastic injection moulding. Thanks for providing its disadvantages also..
