With the improvement in technology manufacturing industries are on the verge of growth. Plastic injection molding is not left behind even as new technology is being invented in the manufacturing industry. This is a process which deals with the fabrication of plastic parts. Many products are manufactured by this process. These products differ in size, complexity, and their application.
For it to operate an injection molding machine is needed, raw material and a mold must be present. During this process, plastic is melted inside the machine and then injected into the mold. The material is cooled after which it solidifies as the final part product.
This process entails four main stages. The first stage is known as clamping. Before injecting the material into the mold, the two halves are first securely closed by the clamping unit. This unit is part of this machine. Each half is attached to the injection molding of this machine in which one half is allowed to slide. The clamping unit which is powered by hydraulic system pushes these parts together and exerts sufficient force to keep it closed during the injections of materials.
After clamping the material are injected into these molds. The materials entering the molds are usually in a molten state. To begin this stage, the raw materials which are in the form of pellets are fed into the machine. Heat and pressure are applied to them making them melt. The molten material is the injected into the molds. Pressure is created that packs and holds these materials into position. The amount of material injected into it is known as the shot. The taken while injecting the materials can be estimated from shot volume, injection pressure, and injection power.
Following injections is cooling of molten plastic. Cooling begins immediately the materials come into contact with the interior wall of this mold. The reason for this process is to allow for solidification of molten material into the desired shape and size. During cooling, shrinkage of the part is likely to take place. For this reason, it is necessary to properly pack the materials during the injection stage. This reduces the rate of shrinkage. It can now remain open until the desired cooling is obtained.
Lastly, is the ejection stage. After cooling, the cooled part is removed through the ejection system. This system is attached to the rear half of this mold. Force is applied to eject the part since while cooling; the part may shrink thereby adhering to it. To facilitate the ejection process, a mold release agent is sprayed onto the surface of mold cavity before the injection of this material.
This process is used to produce thin walled plastic parts for different applications. One of the common is plastic housing which is a thin walled enclosure. The housings are used in several products such as power tools, household appliances, automotive dashboards and consumer electronics.
On its benefits, accuracy is the outstanding; however, there are some other advantages. This process is accurate because it allows fabrication of any form of the part. Despite design restrictions of these molds, the finished parts are usually precise.
