Plastic Mold Injection Molding Is a Fast Growing Process

Plastic Mold Injection Molding is a fast growing process that has gained a lot of momentum in a very short span of time. There are various advantages of using plastic mould Injection Molding process. The major advantage is that it is very reliable and cost-effective. Also, this process produces smooth and finished products that require no further finishing. The equipments involved in plastic mold injection molding are very sophisticated and costly. They are known as injection molding machines. The machinery used are also heavy and some even weigh up to tons of kilogram. But only when these kinds of machines are used the final product turns out to be a quality product. This is so because the plastic molds are fed into these machines and they are heated until they become fluid. This signifies that the machines should bear up high temperature and thus comes the requirement of sophisticated equipments. The plastic mould when poured, takes the shape of the cavity or the mold used and get solidified or settled in it. After some time molded material is ejected out from the cavity. The same cavity can be used to make any number of molds. The mold can be of any preferred shape. The mold has two components namely the injection mold and the ejector mold. The melted plastic mold resin is transferred into the mold and the ejector mold helps in ejecting the plastic mold part after it is solidified in the mold without any damage using ejecting pins. The next procedure is the use of hydraulic or mechanical pressure. Air gets trapped inside the mold and this is done to release the air. This is known as the dwelling process. The air cavities are pushed to one corner of the mold when pressure is applied. Then the fluid is allowed to solidify and the mold is cooled. Finally the solidified plastic mold part is taken out from the mold either manually or automatically.
