Plastic Injection Moulds (PIM) is a common manufacturing procedure for creating a large number of identical parts by simply injecting melted material into a pre-determined mold, called mold. The substance used in the mold is selected, as per the specific requirements of the client and the desired shape and size of the part being produced. Commonly, injection molding is carried out using a host of various materials mostly including plastics, thermoplastics, epoxy etc. The plastic material is sometimes pre-manufactured within the injection mold to ensure that the correct type of plastic for the part is available, prior to the manufacture of the mould.
The most common plastic parts produced by this process are polystyrene pellets and flakes, which are shaped and cooled by means of pressurized hot air. Other popular plastic materials used in this process are thermoplastics, thermoset or polyurethane, acrylic and silicone gels. The term styrene is considered best suited for products wherein high strength is required, at a relatively low price. Thermoplastic is ideal for products that are to be used in a wide variety of applications, such as toys, medicines, industrial devices etc.
Plastic Injection Moulds are usually made in a large-scale factory with the help of large machines. These machines are capable of mixing, dispensing, melting and mixing the required plastic parts, after a series of templates having different thicknesses are manually drawn on computer software. After a series of templates are generated, the melted plastic material is poured into the moulds, depending upon the requirement. This whole process is then operated by trained personnel.
Plastic Injection Moulds can be used for various purposes. It can be used for the production of bottles and cups for beverages, food containers, bags, plates, dishes etc. In the food industry, it is extensively used for the manufacturing of baby bottles and containers, and other food items such as biscuits, cakes, biscuits rolls and pastries. The injection moulds are also used to manufacture paper products. Also, injection moulds are frequently used to manufacture artificial flowers and foliage.
Plastic Injection Moulds have revolutionized the art of manufacturing plastic parts. There is no need to design, create, produce, assemble or maintain a production line for a plastic product anymore. With the help of modern machines, manufacturers can quickly manufacture thousands of plastic parts. Moreover, the production cost of these plastic products has come down tremendously. Therefore, it has become possible to produce, manufacture and deliver products economically.
The plastic products manufactured with the help of injection moulds can be designed and produced easily using a few clicks of the mouse. The quality and production speed of the product can be precisely controlled. They are widely used for plastic parts because they are economical and can withstand high wear and tear. These injection moulds can also be used to produce various other products such as buttons, caps, wires, bolts, screws and many more. In fact, these are preferred by most of the businessmen because they are durable, reusable, quality and low cost.
